FF Chapter 26
| Question | Answer |
|---|---|
| Who certified SCBA’s | NIOSH |
| What makes an SCBA different from a SAR | The user carries the breathing air |
| What must be a facter of any Supplied air respirator used at a hazmat incident | Positive pressure |
| Why are SAR’s not used for firefighting | Potential damage to the airline from heat, fire, and debris |
| When can APR’s not be used | Oxygen deficient or enriched atmospheres IDLH atmospheres |
| What do particulate removing filters protect us from | Toxic dusts Mists Metal fumes Asbestos Some biological hazards |
| What are some air supply respirators limitations | Limited visibility Decreased communication Increased weight Decreased mobility Psychological stress |
| What standards as homeland security adopted for protective clothing used at Hazmat incidents | NIOSH and the NFPA |
| What is structural PPE’s characteristics when it comes to hazmat incidents | Not a substitute for chemical protective clothing Provide limited protection against many hazards Neither corrosive nor vapor right Liquids can soak through Acids/bases can dissolve/deteriorate ppe Gases/vapors can penetrate |
| Where are there gaps that do not create a tight seal with structural gear | Neck Wrists Waist Boot overlap |
| What is high temperature protective clothing designed to do | Protect the wearer from short term exposures to high temperatures |
| What PPE is used that allow for a person to be in total flame for a short period of time | Fire entry suits |
| What is chemical protective clothing designed to afford the wearer | Known decree of protection from a know exposure |
| How can chemical protective clothing contribute to heat disorders | Not impermeable to moisture limiting the transfer of heat from the body through natural evaporation |
| What are the two types of chemical protective clothing | Splash protective Vapor protective |
| What is liquid splash ppe designed for | Protect users from chemical liquid splashes |
| What are the two types of liquid splash protective clothing | Encapsulating or non-encapsulating |
| What are the two primary limitations to fully encapsulating liquid splash suits | Umpire mobility, vision, and communications Traps body heat |
| What are limitations to non-encapsulating liquid splash suits | Does not provide full body coverage Traps body heat |
| What level suit is vapor protective suits generally in | A |
| What must all emergency agencies that commonly use CPC must establish | Written chemical Protective clothing program and respiratory protection management program |
| What is permeation | Process that occurs when a chemical passes through a fabric on the molecular level |
| What is chemical degradation | When a materials characteristics are altered through contact with chemical substances |
| What agency established a set of chemical Protective ppe ensembles | EPA |
| What does a level a ensemble consist of | Highest chemical protection (vapor suit) Highest respiratory protection (SCBA/SAR) |
| What does a level b ppe ensemble consist of | Middle chemical protection (splash suit) Highest respiratory protection (SCBA/sar) |
| What ppe is work when the material is known and is not an idlh | Level c |
| What does a class D ensemble consist of | Lowest chemical protection (uniform) Lowest respiratory protection (none) |
| What comes with the higher level of PPE | Greater associatated risk |
| What are some general selection factors for ppe | Chemical/physical hazards Monitoring/detection readings Physical environments Exposure duration Compliance with regulations Clothing design Material chemical resistance Ease of Decon Interoperability with equipment |
| How does wearing ppe increase risk of heat disorders | Inhibits body’s ability to disperse heat and moisture which is magnified when performing strenuous work |
| What is the most serious heat disorder | Heat stroke |
| Why should you limit caffeine and alcohol intake | Can contribute to dehydration and heat stress |
| How can you prevent cold disorders | Avoiding cold beverages Rehabbing in a warm area Wearing work clothes Being active |
| Why can CPC add to psychological stress | Can be a confining experience Knowing chemicals involved and hazards |
| When should medical monitoring be conducted | Before and after entry |
| What should be included in an exposure record | Type Length Description of PPE Type of decon On scene and follow up medical treatment |
| What does increased comfort in ppe do | Reduce stress |
| What can reduced stress create when working in ppe | Increased proficiency |
| When should equipment be checked for any operation | Before entering the hot zone |
| When should a safety briefing be conducted | Before entering the hot zone |
| What should be included in a safety briefing | Hazards Incident status Tasks to be performed |
| What does exposure mean | A hazardous material has entered or potentially entered your body |
| Where should you don ppe | In the cold zone as close the the entry point as possible |
| What should be the last item removed when doffing | Respiratory protection |
| When should respiratory inspections be performed | After each use Daily Weekly Monthly Annually |
| What should happen after ppe is used at an incident | Any affiliated reports/documentation should be filled out required |
| What is the goal of spill control | Reduce the amount of contact a product makes with people, property, and the environments therefore reducing the harm it creates |
| Why should an IC seek advice from technical resources about equipment | Determine if materials will adversely affect the equipment |
| Why do responders treat absorbent as a hazardous material after use | It retains the properties of the material it absorbs |
| What is adsorption | Molecules of the material physically adhere to the adsorbent material |
| What is used as a temporary mitigation at radiological and biological events | Blanketing/covering |
| What is the goal of vapor suppression | Reduce emission of vapors to atmosphere |
| What must occur after the use of vapor dispersion | Water must be confined and analyzed |
| What should be done when choosing ventilation | Ensure compatibility of atmosphere and equipment Intrinsically safe equipment |
| What form of mechanical ventilation removed the most atmospheric contaminants | Positive pressure |
| What is the disadvantage of dispersion | Spreads material over a wide area |
| What is dilution most often used for | Decon |
| What is neutralization | Raising or lowering the ph of materials making them neutral |
| What is a risk of operating around flammable/combustible liquids | Absorb into ppe which can later ignite if exposed to an ignition source |
| Why should you not direct water at foam blankets | It destroys and washes away foam Blankets |
| What is leak control | Containing the product in its original or new container preventing it from escaping |
| When should a hazmat operations level responder take offensive actions at a hazmat scene | When gas, diesel, natural gas, or lpg is involved Received correct training and ppe |
| What type of tank does not have an emergency shirt off | Corrosive liquid tanks |
| When should responders shut a valve at a fixed facility or pipeline | When directed by facility operators |
| What kind of Decon is the removal of soot from the face, neck, hands and legs | Gross Decon |
| What is an advantage of gross Decon | Conducted in the field |
| What is a disadvantage of emergency Decon | All contaminants may not be removed Emergency Decon can harm the environment |
| When are exposure records required | When a responder has been exposed or potentially exposed to a hazardous material |
| What documents actions during the incident | Activity log |
