FIREFIGHTER HAZMAT OPS PRACTICE
SCRIPT UPDATED 2026 TESTED SOLUTIONS
⫸ Tankers/tenders are primarily used to transport water to the scene and
have a capacity of:
1) 500 gallons.
2) 750 gallons.
3) 300 gallons.
4) 1,000 gallons or more. Answer: 1,000 gallons or more.
⫸ All personnel and equipment exposed to hazardous materials are
considered:
1) contaminated.
2) a chronic hazard.
3) auto-exposed.
4) toxic. Answer: contaminated.
⫸ The bypass valve on a self-contained breathing apparatus is used:
1) during hazardous materials incidents.
2) in emergency situations involving a malfunctioning regulator.
3) to clear the mask of unwanted condensation.
4) to cool the facepiece when high heat is encountered. Answer: in
emergency situations involving a malfunctioning regulator.
,⫸ The procedure for doffing personal protective clothing is:
1) optional.
2) mandated by the National Fire Protection Association.
3) simply a reversal of the donning procedure.
4) required for fire department readiness certification. Answer: simply a
reversal of the donning procedure.
⫸ Which is an acceptable action when overhauling after a vehicle fire?
1) Use a cutting tool to remove the hood and trunk.
2) If the firefighter suspects the fire was incendiary, call for an
investigator.
3) Remove the tires from the vehicle.
4) Coat the entire vehicle in foam and reapply foam every 15 minutes.
Answer: If the firefighter suspects the fire was incendiary, call for an
investigator.
⫸ The process of maintaining continuous possession and control of
evidence from the time of discovery until it is presented in court is:
1) chain of custody.
2) chain of investigation.
3) the investigative process.
4) the scientific method. Answer: chain of custody.
, ⫸ A reaction that is associated with over-pressurization of closed
containers and occurs at a rate of one second or less is called a:
1) rapid relief.
2) Boiling Liquid Expanding Vapor Explosion.
3) crack.
4) low pressure release. Answer: Boiling Liquid Expanding Vapor
Explosion.
⫸ A typical natural gas service includes, in addition to the shut-off
valve, a gas meter and a:
1) remotely monitored valve position sensor.
2) remotely monitored fire sensor.
3) pressure-reducing valve.
4) key mount. Answer: pressure-reducing valve.
⫸ The pressure remaining in a hose or water main while water is
flowing is:
1) friction loss.
2) residual pressure.
3) static pressure.
4) elevation pressure. Answer: residual pressure.
⫸ What limitations of self-contained breathing apparatus (SCBA) use
can be attributed to the psychological boundaries of the user?
