HAZARDOUS MATERIALS SECTION 3 HAZMAT

AHJ's LERP's should provide what information? - answer-AHJ's LERP's should provide guidance on how each department works with other specialists and agencies on specific emergency. Approach from Uphill and Upwind, actions should be calculated and deliberate, and monitoring equipment used bu Hazmat technicians can help access hazards associated; are all examples of what? - answer-Safety Precautions to be observed when approaching and working at hazmat/WMD incidents. Approach suit. Talk about the important details. - answer--Designed for short term entry into flaming enviroments -Not designed for extended stays -Provides level D protection Describe Absorption. - answer-Like a sponge soaking up water, it soaks up and retains a liquid hazmat by using absorbent materials. Does not change the hazmat, and many absorbents are inexpensive and readily available Used in wet or dry decor and effect on flat surfaces Material is considered hazardous waste once absorbed. Disposal problematic and expensive. Swells and becomes Heavy Ex. Clay, Kitty Litter, Dirt, Sawdust, Comercial Boom, Vermiculite, polyolefin type fibers Describe Adsorption. - answer-The molecules of the liquid hazardous material physically adhere to the adsorbent material. Produces heat and can cause combustion Recommended for shallow liquid spills and can be very expensive. Ex. Activated charcoal, silica or aluminum gel, and fullers earth. During critical or emergency situations the responder will always follow the guidance of the ______ and _____ for approved communications equipment and communication policies and procedures. - answer-AHJ LERPs and SOPs Entry suits. Talk about the important details. - answer--Designed for direct fame contact -NOT designed for extended stays -Provides level D protection -Not fire fighters How does adsorption differ from absorption? - answer-Adsorption differs from absorption in that the molecules of the liquid hazardous material physically adhere to the adsorbent material. This process produces heat and can cause combustion. It is important to make sure that the adsorbent used is compatible with the hazardous material in order to avoid potentially dangerous reaction. Law Enforcement Officials. Important information. - answer--Typically wear ballistic protection and no respirator -PPE may be assigned in emergency situations (ex: terrorist attack) Liquid-splash clothing. Talk about the important details. - answer--Tested for 7 specific chemicals and does not protect from vapors (Liquids only) -This type of protective clothing provides both Level B and C protection Once the IAP is established, who will spell out PPE requirements? - answer-Site Safety Plan Operation level responders involved in technical decontamination must do so under the guidance of what? - answer-A Hazmat technician, SOPs or an allied profession Operations level responders always operate under who? - answer-The guidance of the competence level of a hazmat technician, an allied professional, an emergency response plan, or Standard Operating Procedure. Proximity suits. Talk about the important details. - answer--For short term entry into flaming environments -NOT designed for extended stays -Provides level D protection -Breathing apparatus Responders must be familiar with the AHJ procedures for implementing technical decontamination within the incident command system including what? - answer-Decontamination team positions, roles and responsibites Station/Work Uniform. Important points. - answer--Provides level D protection -Affords little to no protection against chemical vapors, gases, or liquids -No respiratory protection Structural Firefighting Protective Clothing. What are the important points? - answer--Used for firefighting operations -Minimal protection -Numerous limitations when used during hazardous material incidents -Most familiar to responders -Provides level D protection The operation of approved communication equipment and normal communication policies and standard procedures should be outlined in what? - answer-The AUJ LERPs. True or False All responders involved in decontamination operations must wear appropriate PPE for performing emergency decontamination operations. - answer-TRUE TRUE or FALSE If responders are adequately protected, only the garments they are wearing or the equipment they are using in the hotline will be contaminated. - answer-TRUE TRUE or FALSE It is important for responders to remember all contaminants must be removed prior to PPE removal. - answer-TRUE This can be done through decontamination TRUE or FALSE There are single combination or ensemble of protective equipment that can protect against all hazards. - answer-FALSE There is NO single combination or ensemble of protective equipment that can protect against all hazards. Types of tools and equipment approved for emergency decontamination tools and equipment can vary depending on what? - answer-The AHJ Vapor-protective clothing. Talk about the important details. - answer--Tested for 21 specific chemicals -Protects against gases and vapors -Highest label of protection and provides Level A protection What allows the responder to stay at a distance from material release and what must they know? - answer-Facility remote valve shutoffs, Must know the hazards of materials and appropriate PPE What are some limitations of respiratory protection? - answer-Claustrophobia and poor aerobic exercise will limit the responder's ability to respond HazMat incidents. What are some skin contact hazards? - answer-Burns, rashes, and absorption of toxic substances through the skin or eyes. What are the components of an incident action plan (IAP)? - answer--Strategies -Tatics -Developed based upon the problem -Current situation summary -Resources needed -Hazard statement -Risk assessment -Site safety plan -Communication plan (including back-up communication) What are the dangers that operation responders must be aware of while working in PPE? - answer-Heat released injuries, and suit degradation What are the indicators and signs of material degradation of the chemical protective clothing? - answer-Stiffness or excess pliability Any tears, cuts, or abrasions Any damage to zippers or other closures Degradation, Penetration(through an opening), Permeation(through a garment) What are the limitations of wearing PPE? - answer--Heat related stress -Psychological issues What are the operations level mission specific responsibilities? - answer--Are not a hazardous materials response team member -Are not trained in the use of specialized protective clothing -Are not trained in the use of specialized control equipment. What are the OSHA guidelines for spill control tactics? - answer-Control, Confinement, Containment and Extinguishment What are the physical factors that can change how responders wear PPE? - answer--Physical condition -Poor agility -Facial features -Stamina What are the three high temperature protective clothing? - answer--Approach suit -Proximity suits -Entry suits What are the two processes to decontaminate and clean up hazardous materials? - answer--Absorption -Adsoprtion What are the two types of chemical-protective clothing (CPC)? - answer--Liquid splash -protective clothing -Vapor-protective clothing What are tools and equipment for technical decontamination? - answer-Hand lines/water, shovels, spill blockers, adsorbent pads, tarps, salvage covers, plastic sheeting What are used during emergency situations? - answer-Pre-established emergency ra
