PROGRAM AT WHEATON Preface Wheaton College, through the Business Services Office, has established a comprehensive, proactive program to protect the health and safety of faculty, staff, students and visitors. As part of our health and safety program, the College has developed a plan to demonstrate compliance with certain requirements of the Occupational Safety and Health Act s Occupational Exposures to Hazardous Chemicals in Laboratories, which applies to laboratories where hazardous chemicals are used. The standard 29 CFR 1910.1450 can be found at http://www.osha.gov/pls/oshaweb/owadisp.show_document?p_id=10106&p_table=standards. A summary of Required Elements for Safety Related Procedures in a Laboratory Facility is included at Appendix A. OSHA requires that employers comply with the standard in seven areas: Occupational exposure monitoring Preparation of a Chemical Hygiene Plan Employee information and training Medical surveillance Labeling and hazard identification Use of personal protective equipment Record keeping Wheaton defines a laboratory to include any setting where small quantities of chemicals are used for nonproduction, experimental purposes. This includes science laboratories and art studios at Wheaton. This document is the College s Chemical Hygiene Plan, or CHP. In addition to our faculty and staff, the CHP is available to all students in laboratory courses, fine art studios, and researchers at Wheaton College. Requests for copies and questions regarding the plan should be addressed to your Department Safety Officer (DSO) or to: Business Services Office Park Hall 205 Wheaton College 508-286-3438 Reviewed 11/09/10 Page 4 of 57

1.0 Introduction 1.1 Policy Wheaton College is firmly committed to protecting the health and safety of faculty, staff, students and visitors from the health and physical hazards in the laboratory through compliance with applicable standards, development and implementation of standardized procedures and the use of recognized prudent practices. An effective occupational health, safety, and accident prevention program is everyone s responsibility. At Wheaton, responsibility for adherence to the Laboratory Safety Policy will follow the regular lines of authority from management to the individual. It is management's responsibility to provide a safe place to work, to develop health and safety rules and guidelines, and to enforce these rules and guidelines. The faculty and staff of Wheaton College Science and Art Departments have the responsibility for implementing the provisions of this chemical hygiene program and practicing safe science and art. It is every laboratory and studio employees' responsibility to follow these rules and guidelines, and to report unsafe conditions to their immediate supervisor for corrective action. This plan recognizes that faculty and trained staff will adopt and tailor these policies, procedures and practices to their laboratory specific needs. Appendix B includes definitions for many of the terms used in this Plan, as defined by OSHA. 1.2 Coverage The standards set forth in this Chemical Hygiene Plan (CHP) are applicable to all laboratory and art studio employees. This includes faculty, staff, teaching assistants, research assistants, laboratory assistants, laboratory technicians and art assistants who are employed by Wheaton College. Laboratory health and safety policies, however, cover only duties and tasks performed by laboratory and art studio employees while physically situated at Wheaton facilities. The CHP does not specifically cover students enrolled at, but not employed by, Wheaton College, but it is strongly suggested that the faculty discuss the elements of the CHP with each student working in a laboratory or studio and communicate the expectation that students conform with all applicable Wheaton policies and procedures. 1.3 Organization, Roles and Responsibilities The Business Services Office administers environmental health and safety programs for the College. The Assistant Vice President of Business Services and Physical Plant serves as the organization s Chemical Hygiene Officer. The authority and responsibility for implementation of chemical hygiene policies at the operating level are delegated by the Business Services Office to the science and art departments. Designated Departmental Safety Officers (DSO s) collaborate and work with the Business Services office to facilitate compliance, disseminate information and promote safe work practices. To implement chemical hygiene policies, the assistance and cooperation of all laboratory and studio staff is necessary. The following descriptions outline key roles and responsibilities of all Wheaton College employees involved in implementation of this Plan. Reviewed 11/09/10 Page 5 of 57

1.3.1 Safety Committee Wheaton College has a Safety Committee comprised of representatives from numerous college departments including Chemistry, Biology, Psychobiology, Physics, Art, Public Safety, Business Services, Physical Plant, General Liability and Worker s Compensation insurance agents. This committee meets twice per year. Contact the Chemical Hygiene Officer for a current list of Safety Committee representatives. The Safety Committee is a team of faculty, staff, administration, and outside resources as necessary, who work collaboratively to achieve regulatory agency compliance, reduce risk exposures and recommend practice/process safety improvements when appropriate.

There are three types of standards in this Plan. 1. Wheaton Policies: These are general, over-arching policies that must be met by all laboratories and departments under all circumstances. These policies were developed collaboratively by the administration, faculty and staff. 2. Standard Operating Procedures or SOPs: These are specific actions that must be taken under specified circumstances. They are more specific than Wheaton policies. 3. Recommended Practices and Guidelines: These are recommended practices that should be followed, depending on the circumstances. These prudent practices provide sufficient flexibility for faculty and technical staff to modify practices to the unique needs of their labs and needs. The words should or may will distinguish these guidelines and recommended practices from the shalls and must language used in policies and procedures. Faculty, staff, students and visitors in the laboratories are expected to be familiar with these standards. The following information is presented to make clear what is a policy, what is a SOP and what is a best practice. All SOPs and recommended practices for handling hazardous chemicals are not found in this document. Each lab may augment this Plan with additional procedures and practices. While the safeguards should protect laboratory workers from unsafe conditions in most situations, there is no substitute for personal knowledge and vigilance when working with hazardous chemicals. Professional judgment is an essential component of practicing safe science and art in the laboratory. 2.1 General Laboratory Standards Policy SOPs Smoking, eating or drinking in laboratories or studios is forbidden. Before leaving the laboratory or studio dispose/disinfect PPE that was used, and wash your hands thoroughly. Avoid working in a lab or studio alone. If working alone is necessary, notify Public Safety of your location with arrival and departure times. Reviewed 11/09/10 Page 8 of 57

Best Practices Learn the location and operation of emergency equipment, blankets, and first aid supplies. Know what to do in case of an emergency. Be properly prepared to do the experiment. Read the written procedures in advance and understand what you are going to do. Act in a responsible manner at all times. No horseplay or fooling should occur in the labs or studios. 2.1.2 Handling Hazardous Chemicals in the Laboratory Policy SOPs Know the hazards of any chemical that you are handling and take all appropriate measures to reduce the risk of an exposure or accident. Use the minimal amount of a hazardous chemical necessary for your work. Keep the laboratory area clean and uncluttered. Good housekeeping is the key to an effective health and safety program in the lab. No work involving hazardous chemicals is to be conducted in a faulty hood or vented enclosure until the problem has been corrected. [Note: Refer to the definitions contained in 29 CFR 1910.1450 and 1910.1200 for hazard classes.] Read the label on the chemical container before you use the chemical. Be sure labels are clearly legible and facing forward on all containers. Keep the lid closed on all containers, except when pouring from or into the container. Do not return unused reagents to the reagent bottle. Common Hazard Classes Aerosol, flammable Carcinogen Chemicals with target organ effects Combustible Liquid Compressed gas Corrosive Explosive Gas, flammable Highly toxic agent Irritant Liquid, flammable Oxidizer Peroxide Reactive Reproductive agent Sensitizer Solid, flammable Toxin Reactions involving pressure build-up are prohibited in laboratory hoods without the appropriate relief equipment and shielding. Do not taste a chemical. Check odors only if instructed and determined safe to do so, by gently wafting some of the vapor towards your nose with your hand. Be sure your work area is adequately ventilated for your experiment. Work in the fume hood if necessary. Keep access open to emergency equipment and emergency EXITs. Do not leave contaminated or dirty glassware or tools in the work area. Dispose of broken glassware in "GLASS ONLY" containers. Dispose of sharps (e.g. scalpels, needles) in approved sharps containers. Place chemical hazardous waste into the satellite accumulation area (SAA) and follow all SAA regulations. Reviewed 11/09/10 Page 9 of 57

Recommended Practices Use only chemicals for which the quality of the available ventilation system is appropriate, as indicated on the applicable MSDS. The DSO shall institute additional control measures and specific precautions for chemical handling, as appropriate. Clean work surfaces with an appropriate cleaner before leaving the laboratory. Appendix C includes recommendations for the handling of glassware in the laboratory. 2.1.3 Protective Equipment and Clothing Policy SOPs Protective equipment (e.g., safety glasses) and clothing must be worn during all operations that require chemical handling. The appropriate level of PPE shall be determined by knowledgeable laboratory personnel, including faculty and laboratory technicians and supervisors. Special goggles or glass must be worn when using lasers or ultraviolet light sources. Contact lenses, which offer no protection against eye injuries, are not to be worn in the laboratory or studio. Chemical splash-proof goggles must be worn when there is the potential that chemical splashes or flying particles may be produced, or if you are working with corrosive material or highly toxic materials. Face shields must be worn when handling very large quantities of hazardous chemicals. Gloves should be utilized when using hazardous chemicals. Check the glove chart in Appendix D to assure that adequate gloves are being used. Sandals, open-toed or open-heeled shoes are not allowed. Shoes that give adequate protection against spilled chemicals or broken glass should be worn in the laboratory or studio. Recommended Practices Safety glasses with side shields are the minimum eye protection that should be worn in the laboratory or studio at all times, whether or not you are actively engaged in experimental work or not. Laboratory coats or aprons are available and should be worn. Long hair should be tied back. Loose-fitting or floppy clothing should not be worn. 2.1.4 Laboratory Emergencies Policy The health and safety of laboratory workers is Wheaton s primary concern. In the event of an accident, injury or potential exposure, the following procedures shall be followed. [Note: See Section 3.0 for additional information about spills and emergency response in the laboratory.] SOP for Injuries in the Laboratory 1. If injured, contact Public Safety for assistance. 2. In an emergency, dial 911 for assistance. 3. Seek prompt medical attention at Sturdy Memorial Hospital or your personal physician. Reviewed 11/09/10 Page 10 of 57

4. Any work place injury requires notification to Human Resources and completion of an accident/incident form by the injured party. HR can assist you in receiving needed medical attention. 5. Notify your supervisor of the circumstances causing the injury and the treatment you receive. 6. Review the first aid section of the chemical MSDS, as necessary. Be aware of how to respond to an injury/exposure to the chemicals with which you are working. SOP for a Fire in the Laboratory: 1. Pull fire alarm, evacuate the area and notify Public Safety. 2. Fire extinguishers are for escape purposes only. 3. Burning Clothing: If an article of clothing catches fire, move directly to the safety shower, roll the person on the floor, or wrap with a fire blanket. Never run. Never direct a fire extinguisher at a person. Get prompt medical attention. 4. Burning Reagents: Extinguish all nearby burners. Small fires in flasks and beakers can usually be extinguished by covering the container. 5. Report all fires, accidents and injuries to Public Safety and your safety officer or department chair. Appendix E includes information with respect to Fire Classification and Fire Extinguishers. 2.2 Ordering Chemicals Policy SOPs Purchase the smallest practical amount of hazardous chemicals to minimize unnecessary storage and reduce the risks of injury or spillage. Know the projected use, hazards and the disposal requirements of any hazardous chemical prior to purchase. The purchase of highly hazardous chemicals -- such as RCRA p-listed acute wastes and peroxide formers -- by a laboratory must be approved by the faculty member responsible for the laboratory. Prepare the laboratory for the arrival of the substance (i.e., establish storage location, post appropriate signs, obtain and check personal protective equipment). Update the chemical database (type, amount, storage location, principle investigator or program coordinator). Recommended Practices Purchase chemicals in plastic containers or plastic coated bottles whenever possible. 2.3 Receipt and Distribution Policy Appropriate precautions will be taken by each department to ensure that hazardous chemicals delivered to the College will be safely received and handled by trained employees and that information (e.g., MSDS) about the chemicals will be retained. Notify Public Safety of any packages that are suspicious in nature or appear to present a hazard (known or unknown). Do not tamper with such packages. Reviewed 11/09/10 Page 11 of 57

SOPs Each department shall identify a common location for receiving and distributing hazardous chemicals. Most departments will facilitate this through department assistants working with the faculty. For example, all Chemistry department chemicals will be received through Room 337 SC for distribution to the requesting Chemistry faculty. Do not accept any chemical whose container is not properly labeled or appears tampered with. Place a copy of new or updated MSDS in the appropriate department binder and forward a copy to the Business Services Office. All food, cosmetic, or drug samples that are to be used as laboratory study materials must be marked with a label stating that they are not for human consumption. Place biohazard labels on such samples when appropriate. Place all chemical containers which are to be delivered by hand within shock-resistant carrying containers or buckets. When transporting gas cylinders, use an appropriate hand truck, never drag or roll cylinder, leave valve cover cap on until cylinder is in place, and handle only one cylinder at a time, use appropriate storage restraints. Before moving containers out of the receiving area or the laboratory, check and tighten caps, taps, or other enclosures. Recommended Practices Collection of sample chemicals from suppliers is discouraged and should be avoided to prevent unwanted inventory or excessive waste disposal costs. This is of particular importance for small sample gas cylinders. Carts should be used when possible. The container and cart should not be left unattended. Whenever chemicals are transported outside the laboratory, the primary container should be placed in a secondary, non-breakable carrier container. 2.4 Chemical Storage Policy Hazardous chemicals shall be properly stored in the laboratory in such a manner to prevent accident and injury, reduce exposures and risks, and minimize the potential for a spill or release. SOPs The procedures listed below are not intended to be all-inclusive, but rather they are designed to serve as the baseline of prudent storage practices upon which more specific procedures, adopted for particular laboratory situations, can be added. Follow specific instructions for chemical storage available from the MSDS, the container label, and by contacting the DSO, as necessary. Ensure that all containers are in good condition and properly labeled. Inspect chemical storage areas at least annually and determine whether any materials should be removed from the shelf because of lack of usage, expiration date, deterioration, or container integrity. Discard such materials, as appropriate, in accordance with college waste disposal policies and practices. Reviewed 11/09/10 Page 12 of 57

Flammables must be stored in approved safety cabinets. The following limits for flammables in a laboratory are not to be exceeded: TOTAL* Class 1 All Classes On Benches 10 gal 20 gal In Lab 60 gal 120 gal Chemical Hygiene Plan Wheaton College *These limits are based upon a 1,500 square foot laboratory. Limits may be lower for smaller laboratory spaces or may be subject to modification by the Norton Fire Department. Use only explosion-proof refrigerators and freezers for storage of flammable liquids. Refrigerators and freezers that are used for chemical storage shall be marked with appropriate signage indicating that no food or drink shall be stored there. Store highly reactive or corrosive liquids in spill trays. Gas cylinders must be fully secured at all times and away from heat sources. Empty gas cylinders are to be stored in the closet off the Science Center loading dock. Full cylinders are to be stored in the marked area inside the loading dock. Store peroxides at the lowest possible temperature consistent with solubility or freezing point. (Liquid or solutions of peroxides should not be stored at or lower than the temperature at which the peroxide freezes or precipitates because peroxides in these forms are extremely sensitive to shock and heat.) Indicate the date of receipt and the date of opening on each container of peroxide forming chemicals. Do not store hazardous chemicals in alphabetical order. Separate hazardous chemicals in storage as follows. These categories can be further classified, as appropriate. Solids o oxidizers o flammable solids (e.g. red phosphorus, magnesium, lithium) o water reactives Liquids o acids o oxidizers o flammable/combustible o caustics Gases o toxic o oxidizers and inert o flammable Recommended Practices Storage on bench tops, or in hoods and sinks should be avoided. Lab sinks and surrounding areas should be kept free and clear of all hazardous chemicals. Ensure that all storage locations are dry and adequately ventilated if needed. Use spill trays, spill and shatter-proof containers, secondary containers, and proper receptacles as needed. Reviewed 11/09/10 Page 13 of 57

Store caustic or corrosive materials near the floor to minimize danger of bottles falling from the shelf. Store bottles of chemicals > 500 ml (especially corrosives and solvents) no higher than 5 feet. Organic acids should be stored separately from strong oxidizing agents to prevent interaction of vapors and corrosion of storage cabinets. Reference material for storage of hazardous materials can be found either on the MSDS or in Prudent Practices in the Laboratory, published by the National Research Council. 2.5 Specific Procedures for Handling Certain Hazardous Chemicals Policy All laboratory workers handling the following hazardous chemicals or chemicals with the following hazards -- shall follow prescribed procedures identified in Appendix F to minimize the risks to workers, students, and visitors. o Corrosives o Peroxides o Mercury o Formaldehyde o Compressed Gases o Flammables o Pyrophoric Materials 3.0 Emergency Preparedness and Response in the Laboratory 3.1 Emergency/Contingency Planning Laboratory employees shall be trained and prepared to respond to several types of emergencies commonly encountered in the laboratory environment. These emergencies may include: Spills of hazardous and non-hazardous chemicals Accidents and injuries, especially those which may result in exposure to hazardous chemicals Fires Electric shock. Responses to these emergencies may include: Evacuation Spill clean-up First aid Fire-fighting (incipient only) for escape purposes. The following sections describe prudent emergency response practices, and outline the policy of Wheaton College on emergency response issues. Preparation for potential emergency situations is the centerpiece of effective emergency preparedness. Reviewed 11/09/10 Page 14 of 57

3.2 Spill Response General In the event of a large spill (e.g., more than one (1) liter of a moderately hazardous substance), the Public Safety department should first be notified. The Public Safety Department will then take the appropriate action, by calling for assistance and contacting appropriate personnel. If an emergency occurs, affected employees and students shall evacuate the workplace and shall not be permitted to assist in handling the emergency. The primary consideration during any hazardous spill response is to avoid exposure and to prevent ignition of flammable material. Secondary considerations include preventing material from going down a drain or sewer, minimizing property damage, and reducing downtime. Each laboratory worker should be familiar with these procedures and trained in their implementation. Appropriate personal protective equipment and other safety equipment should be available and all lab personnel should be familiar with its location and intended use. Initial Procedures for Large Spill Response A. Avoid personal exposure to the substance. o Do not walk into or touch any spilled material. o Avoid breathing any gases, vapors, fumes, or smoke. o If the substance is unknown, leave the area and obtain help. o Do not assume that a hazardous material is harmless just because you cannot smell it. B. Isolate the hazard area and deny entry. o Without entering the immediate hazard area, move and keep people away from the spill. Lock down the lab or room where the spill occurred, if safe to do so. o If the material is a gas or volatile liquid, evacuate the surrounding areas. Pull the fire alarm and exit the building. o In the surrounding area, post warning signs. o Only qualified personnel with the proper protective equipment and clothing shall be allowed in the spill area. C. Obtain help. o Call Public Safety at x3333. o Contact the DSO and Department Chair. o Immediately report all spills to the laboratory management who will in turn coordinate any additional notification requirements. o Contact emergency medical support immediately in the event of any actual or suspected injury or exposure to the hazardous material. Inform medical responders of the material involved. D. If possible, identify the material as soon as possible without risking personal exposure. o If the material cannot be identified as hazardous or non-hazardous, it must be treated as hazardous. o Check the MSDS for hazard data as well as special protection information and handling precautions. o Contact outside expertise (e.g., CHEMTREC @ 1-800-424-9300, manufacturer) for identification if necessary. Reviewed 11/09/10 Page 15 of 57

E. Do not attempt clean-up until further direction is given from qualified personnel. Spills Involving Contamination of Personnel Chemical Hygiene Plan Wheaton College If any harmful chemical comes into contact with your skin: Wash thoroughly, using the eyewash and/or shower as necessary. Call for help as soon as possible. Inform a co-worker and have him/her notify supervisory personnel. Refer to the applicable MSDS. Discard any protective clothing that has been contaminated. When possible, complete an injury/incident report with HR. Obtain medical treatment as needed. 3.3 Spill Cleanup (e.g., mercury, fine powder) 3.3.1. Procedures for spill cleanup (incidental spills only) In the event of an incidental spill, the following procedures should be followed to clean up the spill. These procedures are for incidental spills only small spills that can be safely cleaned up in the immediate work area. Large spills should be responded to and cleaned up by professionals (who will be contacted by Public Safety and/or Business Services). Chemical spill kits are located in each satellite accumulation area and in Rooms 337, 317 SC and the Science Center Main Accumulation Area (SC MAA). Responses to incidental releases of hazardous substances where the substances can be quickly absorbed, neutralized, or otherwise controlled at the time of release by employees in the immediate release area are not considered emergency responses. If the spill is more than 1 liter of a moderately hazardous material, do not attempt cleanup and immediately notify the appropriate authorities. The cleanup procedure for a spill will depend on the location and nature of the spill; different chemicals will require different response tactics rising from the nature of the hazard. For example, procedures for cleaning up a solid differ from those of a liquid spill. Also, the type and amount of equipment required will depend on the chemical spilled. A corrosive liquid acid will be treated differently than cleanup of a spill of flammable liquid. If evacuation of the area is necessary, pull the fire alarm and evacuate the area. Upon reaching a safe destination call the emergency telephone number. For all spills, wear appropriate protective clothing for protection during cleanup procedures. A co-worker assistant, also dressed in appropriate protective clothing, must be present during the cleanup of the spill. 3.3.2 Mercury Spills Use the mercury spill kit provided to each department to clean up spills. Extra kits are available in the SC MAA. Wear plastic shoe covers if mercury has been spilled on floor. Thoroughly wash hands, arms, and face after clean-up is complete. Dispose of the waste in accordance with college regulations. Use plastic waste containers when possible. Do not place elemental mercury waste in drains. Reviewed 11/09/10 Page 16 of 57

3.3.3 Finely Divided Solids Spills (Dusts, Fibers, Powders, etc.) Extremely toxic dusts should be collected by using HEPA filter vacuum cleaners. Examples: elemental beryllium, cadmium, arsenic and their compounds, and barium, thallium and mercury compounds. (Wheaton College does not own a HEPA vacuum, therefore an outside contractor will be called in to perform this type of service.) Oxidizing solids such as nitrates, permanganates, perchlorates, etc., should NOT be dumped with combustible materials such as paper. Decontaminate the contaminated area with an appropriate cleaning agent. 3.3.4 Others Incidental Liquid Spills (1 liter or less of non-highly toxic chemicals): o Consult the MSDS for the chemical for specific cleanup and disposal techniques. o If the spilled material is hazardous, dispose of absorbed material as hazardous waste. o Clean the affected area with soap and water. Incidental Solid Spills: o Do not dry sweep. o Cover the solid material with wet paper towels (using water or appropriate, compatible solvent, scoops, and gloves). Avoid spreading the compound as much as possible. o Carefully pick up the material. o Consult the MSDS for the chemical for more specific cleanup and disposal techniques. o If the spilled material is hazardous, dispose of absorbed material as hazardous waste. o Clean the affected area with soap and water. 3.4 Accidents and Injuries Response All accidents and injuries shall be reported to the DSO or Department Chair and Human Resources, where you will be required to complete a Med-Fax Report. Be sure to report exposures to any hazardous chemicals as well as obvious injuries. All accidents and injuries should also be reported to Public Safety (who will notify the Business Services Office). These reports support follow-up and subsequent medical care, and initiate the necessary documentation and investigation procedures. Treatment It shall be the duty of each employee to see that he or she receives proper first aid treatment for all minor injuries at the time of the accident or injury. In an emergency, dial 911 for immediate emergency medical response. Sturdy Memorial Hospital on Park Street in Attleboro is the health facility to which the College refers all employees for treatment. If your initial medical treatment is at another facility, you may also be required to go for a scheduled appointment at Sturdy Memorial Hospital. After this first appointment with Sturdy Memorial Hospital you may continue treatment with the ISCC (worker s compensation insurance provider organization) or select a doctor of your own. Our worker s compensation insurance company is responsible for payment of reasonable and necessary medical services as outlined in the worker s compensation act, as long as you follow the above procedure. Of special note, you cannot be charged co-payments or fees from any doctor you see for a workrelated injury. Reviewed 11/09/10 Page 17 of 57

Public Safety will notify the Business Services Office whenever facility damage, injury or spills requiring external resources occur. Wheaton College requires that the following be recorded: o All occupational illness o Fatalities o Injuries resulting in one or more lost workdays o Restriction of work or motion o Injuries resulting in loss of consciousness o Injuries resulting in transfer to another job o Medical treatment including first aid. No deficient accident report will be accepted by the College. The report will be returned to the originator whenever: o The report does not provide an accurate account of what happened. o Basic causes are not identified; only symptoms are cited. o Remedial action plan is incomplete. Follow up conversations with the College Injury Review Committee may be necessary. Accident Review Procedures Accident investigation of any accidents or close calls is key to accident prevention. When conducting an investigation, follow these guidelines: o Be objective. o Define faulty situations, practices or processes. o Be thorough. o Once the deficiencies have been examined and analyzed and their potential assessed, the supervisor must select the alternatives which control the causal factors. The Business Services Office and Human Resources will review accident report forms and may discuss the incident with the injured party, DSO and CHC as needed. Upon determination of route cause, an action plan and/or recommendation will be given to correct and prevent a re-occurrence of the incident. The findings and corrective measures may be shared with other members of the institution to promote a more healthful work place. Reviewed 11/09/10 Page 18 of 57

Human Resources will report the following incidents directly to OSHA within 48 hours: o Fatalities o Hospitalization of three or more employees. It is the responsibility of the employee and department head to insure that required accident report forms are completed, and proper College authorities are notified. Emergency Number Call the Public Safety Department at x3333 (available 24 hours) and provide the nature of emergency and exact location. Dial 911 for Norton Emergency Services, if time is of the essence. 3.5 Emergency Medical Response Definition A medical emergency is a medical condition which requires immediate professional medical attention. The injured person or their supervisor shall contact Public Safety who will summon EMS for transport to a hospital or dial 911. Procedures When a medical emergency occurs, the employee involved, or the person discovering the situation, should immediately: 1. Call for help to bring others in the immediate area to assistance. 2. Call the Public Safety Department. o Give the exact location of the emergency, the nature of the emergency, and the name and condition of the employee(s) involved. o Do not hang up before the Public Safety Department does. This ensures that the officers have whatever information is needed to respond effectively. 3. Upon determination that the location is safe, stay with the victim and administer first aid or other support, as required. If an exposure to toxic materials has taken place, obtain information about the health and safety procedures specific for that chemical. This information can be obtained from the departments MSDS notebook or the Department Safety Officer. 4. Give pertinent information to the ambulance personnel. Give a copy of the appropriate MSDS to the ambulance personnel. If the victim was exposed to hazardous materials, give the emergency personnel as much information as possible about the toxicity and nature of the material to which the person has been exposed. 5. Notify the Department Chair, Human Resources and Business Services Office as soon as possible. 6. The employee reporting the emergency must provide all necessary information about the incident within 24 hours so that appropriate accident reports and response plans can be completed. First aid For serious personal injury, first aid should be administered by trained personnel. Public Safety officers are trained in first aid and cardiopulmonary resuscitation and can respond to any location on campus within three minutes. Reviewed 11/09/10 Page 19 of 57

If the location is determined safe and if a victim is down, do not leave them or the immediate area. Yell for help or call from a nearby phone. Stay with the victim until assistance arrives. Remain in the area after help arrives to answer questions and provide assistance, if requested. Minor first aid cases (minor cuts, bruises, burns, etc.) will be handled at Sturdy Memorial Hospital, as previously outlined. Bring victims suffering from over-inhalation of gases, vapors or dust to fresh air and check the MSDS for next steps. All cases will be sent to the hospital. For skin and eye overexposure to corrosive chemicals or irritants, the first few seconds after contact are critical and immediate flushing of the eye may prevent permanent damage. Wash eyes and skin continuously with large amounts of water for 15 minutes. Remove contaminated clothing. All cases will be transported to the hospital. Victims of electric shock will be transported by EMS to the hospital. 3.6 Fires/Explosions/Evacuations Response If you discover a fire or witness an explosion: o Turn on the alarm. Manual alarm stations are located throughout the building at each exit doorway, or dial the Public Safety Department. o When contacting the Public Safety Department, give the exact location of the fire or explosion and your name. Do not hang up until all relevant information has been provided. o Evacuate the building and proceed to a safe area. Fire extinguishers Each laboratory employee must assure that functional A/B/C and carbon dioxide fire extinguishers are accessible in his/her work area at all times. If this is not the case, the supervisor must be notified immediately. Whenever a fire extinguisher is used, it must be exchanged for a fully charged, sealed extinguisher. A/B/C extinguishers are effective on virtually every type of fire including paper, wood, solvent, oil, electrical, organic, etc. Contact the Grounds Department to report defective, missing or extinguishers needing to be recharged. Extinguishers are to be used for escape purposes. General evacuation Become familiar with the locations of the two closest exits in case of an evacuation. For a quick and orderly evacuation of a building, all personnel must familiarize themselves with the exits and the alternate exits in the area of their work station/office, etc. When the fire alarm signal sounds, proceed immediately to the nearest exit in an orderly fashion. Do not stop or return to laboratories, desks, washrooms, etc. to pick up personal items. When the alarm sounds, leave the building. If possible, shut down any other equipment that is left running which would cause additional problems. Also close office doors and windows if time permits. Do not use an elevator. Do not enter a building until the "all clear" has been given by designated campus staff or the fire department. All evacuated personnel are to meet at a pre-designated department safe site to be accounted for and if necessary assisted. If your department needs assistance determining a site please contact Public Safety or Business Services. Reviewed 11/09/10 Page 20 of 57

All department heads are to account for the people in their respective departments to ensure that everyone has left the building. 4.0 Control Measures 4.1 Hazard Identification, Characterization, and Control Control measures to reduce employee exposure to hazardous chemicals should be implemented, where feasible and appropriate, to ensure that laboratory and studio employees' exposures to OSHA regulated substances do not exceed the permissible exposure limits specified in 29 CFR part 1910, subpart Z. At Wheaton College, the faculty-scientist, laboratory instructor, laboratory staff, art studio faculty and art studio staff shall identify chemical hazards and detect the release of hazardous chemicals using methods and observations appropriate for the chemical and scientific process in use. All members of the Science and Art departments will be vigilant in promotion of safety and in the control of hazardous chemicals. In addition, laboratories and studios shall keep up-to-date chemical inventories and collections of Material Safety Data Sheets (MSDS) for purposes of hazard identification and communication. This information will be coordinated with the Business Services Department for central record keeping. 4.2 Review of Chemicals Each faculty member and/or principle investigator should attempt to use the least hazardous chemicals in their respective laboratories. Each faculty member shall review the chemicals to be purchased in their respective laboratories and studios. Purchase of any highly hazardous substances must be pre-approved. Review of chemical need is to be performed by the faculty member, the DSO and the Department Chair. If they determine that the purchase of the chemical is warranted, they will set guidelines for the selection of controls (engineering controls, personal protective equipment, special hygiene practices, etc.) based on the level of physical and chemical hazard risk. Following purchase approval, the DSO and departmental Chemical Hygiene Committee can implement the selected control measures. Whenever tasks involve work with particularly hazardous substances -- including select carcinogens, reproductive toxins and/or substances with high acute toxicity -- specific consideration shall be given to the following provisions for additional employee protection: specification of designated area(s) use of containment equipment such as fume hoods procedures for safe removal of contaminated waste decontamination procedures. Selection of suitable control options for additional employee protection shall be based on the professional and technical judgment of the departmental faculty, in consultation with the departmental chemical hygiene committee and DSO, as requested. Business services will be consulted as appropriate. Control measures should be documented in a department standard operating procedure. Reviewed 11/09/10 Page 21 of 57
