Firefighter PPE Flashcards
What is PPE?
Personal protective equipment
What is SCBA?
Self contained breathing apparatus.
What is a PASS device?
Protection and personal alert safety system.
What structural protective clothing is required by NFPA 1971?
Helmet, protective hood, protective coat and trousers, gloves & boots.
List two guidelines for proper care and maintenance of helmets.
Remove dirt and soot from the shell,Replace damaged helmets, replace scratched or cloudy face mask, inspect suspension system.
What are four common respiratory hazards associated with fires and other emergencies?
Oxygen deficiency, elevated temperatures, smoke, and toxic atmospheres.
What would be considered a oxygen deficient atmosphere?
An atmosphere containing less than 19.5% oxygen.
What is hypoxia?
A condition caused by a deficiency in the amount of oxygen reaching body tissues.
What is pulmonary edema?
Accumulation of fluid in the lungs.
Asphyxiation is?
A condition that causes death because of a deficient amount of oxygen and an excessive amount of carbon monoxide in the blood.
Name the four factors that are responsible for the types and amounts of toxic gases that are released in a fire.
Nature of the combustible, rate of heating, temperature of the involved gases, and oxygen concentrations.
What factors affect a firefighters’ ability to use respiratory protection effectively?
Physical, medical and mental.
What limitations of the protective breathing apparatus should a Firefighter be aware of?
Limitations include those of the wearer, the equipment and the air supply.
When should a Firefighter check their air supply? (5)
- At the beginning of your shift
- When donning the SCBA & opening the cylinder.
- while working/5-10 minute intervals
- during egress from the hazard zone
- when refilling or replacing a cylinder.
What are the four basic SCBA component assemblies?
- Harness assembly
- air cylinder assembly
- regulator assembly
- facepiece assembly
What is a harness assembly?
A rigid frame with straps that hold the air cylinder on a firefighters back.
What is an air cylinder assembly?
Includes cylinder, valve, pressure gauge and PASS device in some units.
What is regulator assembly?
Includes high pressure hose with low pressure alarm, bypass valve, and a pressure reducing device.
What is Facepiece assembly?
Includes facepiece lens, an exhalation valve and a low pressure hose if the regulator is sepperate.
What are PASS devices designed to do?
To alert others that a Firefighter has stopped moving and may be in distress.
What (5) checks should be made immediately prior to donning SCBA?
- Check to make sure cylinder is full.
- check remote and cylinder gauge to ensure they read within 100 psi of the same pressure.
- check harnesses assembly and facepiece to ensure all straps are fully extended.
- operate all valves to ensure they function properly and are left in the correct position.
- check your PASS device.
What should the daily/weekly check of protective breathing apparatus include? (8)
- Cylinder pressure (90% capacity minimum).
- All gauges
- Low pressure alarm
- All hose connections
- Facepiece
- Harness system
- All valves
- Built in PASS device
What actions are recommended should a firefighter become separated from team members?
- Use radio if you have one/ declare a mayday
- Follow department SOP
- stop and think
- how did you get where you are
- downstairs, upstairs
- left turns, right turns - Hold your breath and listen
- noise from other personnel
- hose and equipment operation
- sounds that indicate location of fire - Remember the different methods to find a way out
- follow hoseline out (trust your bros)
- crawl in a straight line
- crawl in one direction
- call out
- break window or breach wall to escape - Lastly, lie flat on the floor next to the wall so you will be easier to find if you feel you may lose consciousness
What is a hydrostatic test?
A testing method that uses water under pressure to check the integrity of pressure vessels.
Air supply duration will vary with the following . (7)
- Size of cylinder and beginning pressure.
- Firefighter conditioning
- Task being performed
- Level of training
- Operational environment
- Degree of stress
- Other variables
