2 Hazmat PPE s for FTFD 2 ABSTRACT This research was conducted to comprehensively determine the personal protective equipment for hazardous materials response appropriate for my department. The first consideration will need to be the basic mission of my department. Secondly, our policies that carry out this mission and reflected by standard operating guidelines would be reviewed. If there is a need to review and revise these policies, now is the time to do it. All training, equipment, PPE, and expectations are based on these S.O.G.s. We need to develop these S.O.G.s to the point where we are satisfied with them, then we may base all purchases on our expected operations. We must evaluate four factors. First, we need to determine the hostile environments we have the probability and possibility to encounter. This will allow us to make some judgments applicable to our jurisdiction, regarding capabilities and vulnerabilities. Our needs must be directed at the probabilities, and also allow for possibilities. We need to determine what tasks will need to be performed. What is our local department s capability? Our operations must be guided by policy guided by frequency of use, capabilities, training requirements, and efficiency. The tasks we perform will determine the protection needed. Mission Of The Department The following is our mission statement: INTRODUCTION The mission of the Ft. Thomas Fire Department is dedicated in serving the citizens to prevent loss of life, personal injury, and property damage through emergency response, current departmental training, fire Prevention, and community education. The department will provide emergency medical services at the level of advanced life support towards the health, safety, and well-being of the patient/s. The department will provide optimal services in an efficient manor to the needs of our community and recognized by our community and our peers as leaders in the event of an emergency. The department will set examples of professionalism regardless of rank or position and actively participate in community events. The department will assist neighboring fire departments through mutual aid agreements to the extent that the City of Ft. Thomas is not left in harms way. The mission says we will engage in emergency response to prevent loss of life, injury, and property damage. It also says we will provide medical care at the level of advanced life support. It says we will provide these optimal services in an efficient manner. It mentions participation in the mutual aid system. This tells us

3 Hazmat PPE s for FTFD 3 that we need to determine what needs we have, how we can most efficiently meet these needs, and that this may be with the assistance of an outside agency. Our needs are based on probability of incident type and the possibility of incident severity. This would require a judgment or a calculated risk analysis. Risk The overall risk is divided into accidental risk and intentional risk. One could consider that our accidental risk has not changed significantly since 9/11/01, and that our risk from intentional events has. However, to some extent the vigilance to safety in the hazardous materials industry has increased do to criminal threat considerations, and this has improved accidental safety to an undetermined degree. Our criminal risk of a harmful incident was formally self-assessed in City of Fort Thomas, Ky. Risk Assessment Needs Assessment Vulnerability Assessment Threat Assessment Desired Capabilities Current Capabilities Shortfalls or Gaps This part of our risk was divided into vulnerabilities and threats. Our needs are based on this overall risk and tells us where we need to be or desired capabilities. We measure where we are currently, and the difference between current and desired capabilities represents our shortfalls. The shortfalls represent resources that include PPE. The possibility of death, injury, or long term health hazards are all risks than need to be lowered or eliminated.

4 Hazmat PPE s for FTFD 4 These are methods to do this: 1 st choice- elimination of the risk, 2 nd choice- lowering of the frequency, 3 rd choice- elimination of the consequence, or 4 th choice - lowering of the consequencepriorities We do not always have the financial resources to provide for all needs immediately and we must prioritize. When looking at hazards, we may rate the problem per types of incidents. Then each type of incident would have certain common hazards. These hazards could be predicted to some degree in fixed facilities, but not in transportation incidents. This prevents us from relying on prediction of hazards to equip ourselves. We must be prepared using an all hazard approach. However, we can control what personnel s roles would be. This determines the hazard level.

5 Hazmat PPE s for FTFD 5 Expected Probable Hazards Our department is expected to perform on a Hazardous Materials Operations Level. This will not include offensive operations. Offensive operations will be conducted by regional hazardous materials personnel. NFPA 472 states that the operations level should be designated with competencies for various responsibilities. There are core competencies and there are mission specific competencies. The core competencies are analyzing the incident, planning the response, implementing the response, and evaluating the response. Mission specific competencies include technical decontamination, mass decontamination, product control, air monitoring and sampling, victim rescue and recovery operations, evidence preservation and sampling, and response to illicit laboratory incidents. After we more clearly define the roles that our department and that of the regional team play, we would be able to know the mission-specific competencies. Presently, the core competencies of the operations level match the role our department plays. The missionspecific competencies listed are performed by the regional team.

6 Hazmat PPE s for FTFD 6 Elements of a Personal Protection Program Personal protection equipment can obviously prevent harm, but also cause harm to the user. This harm can be caused by both incorrect use and malfunction of the equipment. Elements of a comprehensive program should include: 1. Hazard Assessment - This has been elaborated on earlier. It includes a hazard assessment of chemicals stored, transported, or used in the community. 2. Medical Monitoring of Personnel The entirety of evaluation of personnel s fitness for duty prior to use, and medical monitoring during and after emergency incidents. 3. Equipment Selection The is the focus of this report and considers the combination of:environment encountered i. Toxicity ii. Flammability b. Personnel Objective i. Offensive ii. Defensive c. Personnel that will use the equipment 4. Training Must have an effective training program 5. Inspection Equipment must be inspected at acceptance, at regular intervals prior to use while being stored, and just after use if reusable. 6. Maintenance - Equipment must be maintained as applicable per the manufacturer s guidelines. 7. Storage - Equipment must be stored per the manufacturer s guidelines in order to prevent damage and extend the useable life. 8. Respiratory Protection Program This program should exist in fire departments as SCBA are routinely in use. This includes:

7 Hazmat PPE s for FTFD 7 a. Policy that address factors affecting the mask seal such as facial hair, eyeglass use, chewing gum, or chewing tobacco. b. Medication use in addition to overall fitness for duty evaluation. Available Types of PPE The EPA, OSHA, and the NFPA all have standards applicable to levels of personal protection. Considering that each has a differing mission and role to play, and that they advocate for different stakeholders, this should guide us on which we will use to follow in defining out personal protection. Two of these are promulgate law, the Environmental Protection Agency, and the Occupational Safety and Health Administration. The EPA is primarily concerned with protecting the environment, and OSHA is primarily concerned with protecting the worker. However, these laws are defined by an administration of government that may be effected to some degree by political considerations. However, the standards are law. The National Fire Protection Association is a minimum standard written through a consensus derived from firefighters, construction industry, manufacturers, and other groups. These standards are not law. Many thousands of hazardous materials first responders are part of an association that advocates for safety. This association is called the International Association of Fire Fighters. This organization has developed training and lists the National Institute for Occupational Safety and Health as a source for its curriculum. This curriculum meets OSHA and NFPA standards. NIOSH was created by the same law in 1970 that OSHA was created from. OSHA creates regulations and enforces them. NIOSH conducts scientific research and makes recommendations for regulations. One can not assume that all recommendations are followed. NIOSH would seem to be THE place for the most up to date and stringent information for protection. The most specific protective information and protective material compatibility information comes from the manufacturer. This would appear to be the fox watching the hen house. However, the financial disincentive derived from legal liability from human injury and/or death drives these industries to thoroughly study their product and disseminate information to the public. However, the material safety data sheet

For example the MSDS for chlorine produced by BOC Gases, of Murray Hill, New Jersey specifies protection in this way: The responder then needs to take this information and then match up a personal protective complement that is sufficient.

A work uniform affording minimal protection: used for nuisance contamination only Optio n Hazard has been identified. Requires highest level of protection for skin, eyes, and respiratory based on either the measured (or potential for) high concentration of vapors, gases, or particulates; or high potential for splash, immersion, or exposure to unexpected vapors, gases, or particulates that are harmful to or capable of being absorbed through the skin. High degree of hazard to skin are known or suspected, & skin contact is possible. Operations in confined, poorly ventilated areas & absence of conditions requiring Level A have not yet been determined. Optio n Hazard requires high level of respiratory protection, but less skin protection. Less than 19.5 percent oxygen. Presence of incompletely identified vapors or gases is indicated by a direct reading organic vapor detection instrument, but vapors & gases are not suspected of containing high levels of chemicals harmful to skin or capable of being absorbed through skin. This involves atmospheres with IDLH concentrations that present severe inhalation hazards & that do not represent a severe skin hazard; or that do not meet the criteria for use of air purifying respirators. The atmospheric contaminants, liquid splashes, or other direct contact will not adversely affect or be absorbed through any exposed skin; The types of air contaminants have been identified, concentrations measured, and an air purifying respirator is available that can remove the contaminants; and All criteria for the use of air purifying respirators are met. No known hazard & no potential for splash, immersion, or unexpected inhalation of or contact with hazardous levels of any chemicals.
