PPE, Product Control, and Decontamination Flashcards
Why is respiratory protection the most important part of firefighter PPE when it comes to dangerous goods?
Because the primary route of entry of dangerous goods into the body is inhalation.
What are the two primary types of SCBA?
Open-circuit and closed-circuit
True or false, only negetive pressure SCBA equipment is allowed a dangerous goods incidents.
False, only possitive pressure SCBA are allowed at dangerous goods incidents. There is not such thing as negetive pressure. The alternative to possitive pressure is pressure demand
List some advantages of an open-circuit SCBA.
- Independence
- Maneuverability
List some disadvantages of the open-circuit SCBA.
- Heavy
- Limited air supply that can limit available time to perform tasks.
- Facepiece can fog
True or false, you cannot use a SAR on fire incidents.
True, because the supply hose can be esily damaged.
What is an advantage of a SAR ovet an SCBA?
-It is lighter
What are the three kinds of Air Purifying Respirators?
- Particulate removing
- Vapor and gas removing
- Combination of particulate and vapor/gas removing
When should you not use APRs?
When you do not know what dangerous goods are in the atmosphere.
True or false, there are some APRs that are able to filter all types of dangerous goods.
False, even the combined particulate and vapor/gas APRs cannot filter out all dangerous goods or dangerous situations like low oxygen atmospheres.
True or false, you cannot use APRs in areas that are concidered IDLH.
True
Is structural fire fighting protective clothing able to protect the wearer from all dangerous goods hazards?
No, they are no able to prevent toxic chemicals from being absorbed through the material. Vapors, fumes and gases can also penetrate the clothing.
Name the one type of PPE that can protect against all the hazards and dangerous goods that fire fighters may encounter at incidents.
There is no piece of equipment that protects against all hazards.
What do you do with your PPE if it is exposed to a permeating substance?
You must discard it as it could cause long term exposure issues otherwise.
True or false, Level A PPE ensembles provide the most protection.
True
What is a TECP suit?
-Total encapsulation chemical protection
What is the difference between a Level A PPE ensemble and a Level B PPE ensemble?
They both have the same level of respiratory protection as Level A but it has lesser skin protection.
True or false, it is possible to have too much PPE for a given situation to the point where it can be dangerous to the wearer.
True
When entering the hot zone or an IDLH zone, what five questions must you ask yourself?
Radio Equipment Air Details of your assignment Yes to all the above queations.
What is the difference between contamination and exposure?
They are very different: Contamination means that something is rendered impure due to another substance being mixed with it, and exposure means that a dangerous good has entered or might have entered your body.
Why is it important to prevent contamination at a daangerous goods incident?
Because comtamination can cause reactions that increase the likelyhood of exposure.
True or false, you cannot kneel or sit down when you are wearing chemical protection clothing.
True, because they could tear
True or false, when doffing CPC, the assistant is only allowed to touch the interior of the CPC.
False, they are only allowed to touch the exterior. This helps prevent cross contamination.
What is a synonym for spill control?
Confinement
Is spill control an offensive or a defensive operation?
Defensive
True or false, gases and solids can be included in spill control.
True
What are the three primary tactics used in spill control/
- Building damsor dikes
- Catching the dangerous good in a container
- Chanelling the dangerous good into a location for collection.
List five methods of containing a spill of dust, vapors, and gases.
- Spraying a fine spray of water on it.
- A layer of earth
- Plastic sheet
- Salvage covers
- Foam blankets on liquids
How do you contain an airborn vapor?
Cover with vapor suppressing foam
How do you contain a dangerous goods surface liquid dispersing in a stream shape?
Dig a ditch to direct the dangerous liquid to a place where it can be removed.
How do you contain a dangerous goods surface liquid in a pool shape?
-Cover with an absirbent pillow.
How do you contain a dangerous goods surface liquid dispersing in an irregular shape?
-Spray slightly contaminated surfaces with water.
How do you contain a dangerous goods iquid dispersing in a river?
Place absorbent booms across the river
How do you contain a dangerous goods dust cloud?
Set up ventilation fans to disperse it
How do you contain a dangerous goods dust pile?
Cover with a tarp
How do you control an airborn gas spill?
Pray gas cloud with fog stream.
Describe the order in which CPC is donned
- CPC
- Work boots
- SCBA
- SCBA facepiece
- Secure CPC hood onto SCBA
- Hard hat
- Inne gloves
- Outer gloves
- Connect SCBA regulator to facepiece.
What is the difference between absorption and adsorption?
An absorbent takes a liquid inside of its inner pores and an adsorbent adheres materials to the outside.
Is charcoal an absorbent or adsorbent?
Both
True or false, negative pressure ventilation is more effective than possitive pressure ventilation on dangerous goods spills inside of a structure.
False
Which dangerous goods control technique may require government approval?
Dispersion
Where in the ERG can you find the information for which foam to use when dealing with a flammable or combustible liquid?
Orange pages
What is an emulsifier?
It is a foam that mixes with flammable liquids and seperates them into tiny droplets that are rendered nonflammable.
True or false, if a flammable liquid pool is more than 1.5 centimeters thick, emulsifiers will not be effective.
False, emulsifiers can be effective in liquid up to 2.5 centimeters.
True or false, all class B foams are allowed, with some special exeptions, are allowed to be used in both fire suppression and vapor suppression.
True
What is the only type of foam that can be directly plunge into a flammable liquid spill?
Fluoroprotein foams
Give the ratios that classify Low, Mid, and High-expansion foams.
<20:1
20:1 to 200:1
>200:1
What is the only action that operations level responders are allowed to perform for leak control?
Shutting off a valve to stop the leak
Where are cargo tank shut off devices typically located?
There is typically one behind the cab and one at the rear of the tank.
