1.1 Introduction It is a priority goal of Rochester Public Schools to promote a safe and healthy workplace with safe work practices. In accordance with this, the district has implemented this Machine Guarding Program to enhance the protection of students and staff from the hazards of dangerous equipment and machinery. Any part, function, or process which may cause injury must be properly safeguarded. When the operation of a machine or accidental contact with it can injure the operator or others in the vicinity, the hazards must be either controlled or eliminated. 1.2 Authority and Reference OSHA 29 CFR 1910.211 OSHA 29 CFR 1910.212 OSHA 29 CFR 1910.213 OSHA 29 CFR 1910.219 ANSI 01.1-1975 ANSI/ASME B11.19 AFOSH STD 127-12 Machinery and Machine Guarding General Requirements for all Machines Woodworking Machinery Requirements Mechanical Power Transmission Apparatus Safety Requirements for Woodworking Machinery Performance criteria for the design, construction, care, and operation of guarding when referenced by other B11 machine-tool safeguards.

1.4 Responsibility for Compliance Following are the responsibilities of the Health & Safety Coordinator in relation to machine guarding: Inventory all fixed equipment in Industrial Technology Classrooms (Wood Shop, Auto Shop, Metal Shop, and maintenance areas). Provide training to employees regarding machine safety and machine guarding including the hazards of machines and the importance of proper machine guards. Assist in the proper selection and maintenance of machine guards. Assist in machinery inspections as necessary. Following are the roles and responsibilities of the Industrial Technology Staff: Train assigned students on the specific machine operating rules in their areas. Monitor and inspect to ensure machine guards remain in place and function on a regular basis. Immediately correct or notify the Facilities Coordinator of machine guard deficiencies. Do not remove machine guards unless equipment has been locked and tagged. Do not operate equipment unless guards are in place and functional. Replace machine guards properly. Only trained and authorized employees will be allowed to remove machine guards. Ensure all new equipment meets the requirements of this program and the machine guarding requirements of OSHA, MDE, and/or ANSI best practice standards. Perform inspections of machinery that meet the following criteria: o The operator and machine are equipped with the safety accessories suitable for the hazards that may be encountered during the job. o The safety equipment is in working condition and in place. o The machine operator is properly trained. o Documentation of any problems, deficiencies, and ways to correct the problems associated with the machine. 5
1.5 Machinery Inventory See section in binder for list of Machinery and deficiencies noted. 1.6 Machine Guarding Requirements The following are the requirements of all machinery located within the Rochester Public School District. All machinery will meet or exceed the following requirements of this program: Guards will be affixed to the machine where possible and secured. Guards must prevent hands, arms, or any part of the operator s body from making contact with hazardous moving parts. A good safeguarding system eliminates the possibility of the operator or those nearby from placing parts of their bodies near hazardous moving parts. Guards will not create an accident hazard themselves. Guards should not create interference that would hamper the operators from performing their tasks comfortably. The point of operation that may expose an operator to injury or hazard must be guarded. Guards should be affixed to machinery in a manner that is not easy to remove or tamper with them. Guards and safety devices should be made of durable material that can withstand the conditions of normal use. All fan blades that are less than 7 feet above the floor or working level must be guarded with a guard that has openings no larger than ½ inch. All machinery designed for fixed location will be securely anchored to the floor or working surface to prevent walking or moving. Examples of such machinery include: drill presses, bench grinders, band saws, and circular saws. Guards should prevent objects from falling into moving parts resulting in the objects becoming projectiles. 1.7 General Color Coding Requirements The following are general requirements for color coding: Machines will be color coded with safety orange where there is an intermediate level of hazard. Examples include: hazardous parts of machines that may cut, crush, or otherwise injure. Guards and protective covers should be color-coded with safety yellow. This designates that dangerous parts of machinery or energized electrical components are contained inside the guard; therefore, caution must be exercised. Safety red shall be the basic color for the indication of danger and on devices used for emergency stopping of machinery. 6
1.8 General Safety/Housekeeping The following is a list of requirements pertaining to housekeeping issues that will be implemented in all industrial technology classrooms and maintenance areas: All floors and aisles will be kept in good repair and be free from obstructions such as protruding nails, splinters, holes, or other tripping hazards. Floors in working areas will also be kept clean to prevent slipping and will also be provided with an effective means to prevent employees or students from slipping. Aisle ways and passageways will be kept open and clean to maintain safe egress. All injuries will be reported regardless of severity. Injuries to instructors or staff must be documented through District Insurance on the First Report of Injury, and cases that are considered recordable cases must be documented on the OSHA 300 form. Injuries to students will also be reported regardless of severity and will be documented through site specific paperwork and kept on file at a minimum for the duration of the school year. No food is allowed in a technology education shop area. Eating, drinking, chewing gum, or applying cosmetics is not allowed in the shop area. Exposures will be minimized by using appropriate personal protective equipment and apparel (i.e. eye protection, machine guards, Tyvek aprons, or coveralls). Dust collection systems will be used in areas where woodworking machinery is being used. At minimum an 18-inch clearance must be maintained between storage materials and the height of fire sprinkler heads or 24 inches between the materials and the ceiling if no sprinkler system is installed. Storage of materials must not create a hazard. Overhead storage must be stable and secure. Large objects with heavy weights will not be stored overhead. In cases where large heavy objects need to be stored overhead, staff and students will be required to wear head protection. Do not exceed weight limits of shelving units and mezzanine areas. At minimum, a space of 36 inches will be maintained for access to all electrical boxes and utility controls. Tools, equipment, and machinery may not be altered for use other than that for which they are intended by the manufacturer. Instructors, employees, and students will know the location of and maintain the accessibility to all safety equipment. Any liquid spills will be cleaned up immediately with the proper clean up material. Students and staff must read all labels and material safety data sheets (MSDS) prior to clean up. Vacuums will be used to keep work areas clean and free of debris. Compressed air must not be used to clean dirt and dust from equipment, clothing, or skin. Only tools, equipment, and machinery that are properly maintained and adjusted may be used. Tools will not have paint or tape on them to hide cracks or defects. Defective tools will not be used. They will be destroyed and disposed of immediately to prevent further use. 7
1.9 Clothing and Safe Dress Requirements The following precautions pertain to acceptable clothing and safe dress procedures to be implemented in the technology education classrooms. Instructors are responsible for ensuring that students are informed as to the requirements for wearing apparel that is suitable for the type of shop activities that will be performed and the hazards involved. Individuals working with machinery or in other hazardous operations will wear clothing that is well fitted with no loose or flowing articles. Shirts must be tucked in and short sleeves are considered the best for preventing these articles from being caught in rotating or moving parts of machinery. Instructors or individuals who have long hair and who work around machinery with moving or rotating parts must wear adequate hair-covering to prevent hair from possible entanglement in the machine. Jewelry such as rings, pendants, necklaces, dangling earrings, and watches will not be worn when working with machinery that has moveable or rotating parts. Shoes are to be well fitted with good soles and heels and of a style that completely covers the foot. Open-toed shoes such as sandals or lightweight shoes will not be allowed in any of the shop areas during shop activities. 1.10 Personal Protective Equipment Engineering and administrative controls that eliminate the hazards of these machines and do not rely on the operator s behavior to maintain a safe working environment are considered the best and most reliable means of safeguarding. Therefore, engineering controls are considered the best choice for controlling or eliminating these hazards. However, in cases when engineering controls are not available or cannot control or eliminate the hazard of the machine, operators will be required to wear protective clothing or personal protective equipment. The individual must always consider the following: Appropriate protective equipment for a particular hazard(s). Keep maintained, in good and clean condition. Properly stored when not in use to prevent damage and loss. Destroy and replace immediately whenever equipment is damaged or considered no longer adequate for use. Replace immediately if equipment is lost. Course instructors and the safety department will have the primary responsibility for implementation of the PPE program related to the shops. This includes the following: Conducting a hazard assessment in their areas to determine what types of PPE to use and what the hazards are. Purchasing the necessary equipment and signage. 8
Ensuring that all individuals who work with any type of hazardous machinery are trained on that machine and the proper care, cleaning, and maintenance of the PPE. Ensuring that all individuals who work around or in the area of hazardous machinery wear the appropriate PPE. Replace or repair all defective PPE immediately. It is important to remember that in some cases protective clothing and equipment may create an additional hazard to the user. For example, a protective glove could get caught in movable parts of a machine, or a respirator or face shield could hinder the vision of the wearer. 1.11 Emergency Medical Procedure In the event an employee or student is injured due to a mechanical hazard, that employee or student is to immediately seek medical attention. Emergency medical attention will be obtained by the following means, depending on the severity of the injury: Contacting the building nurse Dial 911 Seeking medical or first aid attention at the medical facility closest to the site of the accident. 1.12 Training Employees and students will be trained on all machinery or equipment they will be using. Only trained personnel or those undergoing supervised on-the-job training will be allowed to operate shop machinery or equipment. All other individuals will be trained in the proper operation, safety procedures, hazard recognition, and emergency shutdown processes for each piece of machinery or equipment they might use prior to its use. The operator training programs will be tailored specifically to an employee s or student s work area. At a minimum, the training program will include the following: The nature of the hazard for each piece of machinery or equipment. Proper operation and shut down for each piece of machinery or equipment. Safety procedures for machinery that requires special set-ups for each tool. How work will be performed in a safe manner. In addition to this, training will require the employees to demonstrate their proficiency and knowledge on the skills required to operate each piece of machinery safely. The supervisor/instructor must determine that each employee or student knows and understands the features of the equipment, all applicable safety rules, and is skilled in the operation of the equipment. All training will be documented the Machine Guarding binder, which will be retained for a minimum of three years. 9
