Safety and Health Flashcards

Two firefighters must enter an Immediately Dangerous to Life or Health (IDLH) atmosphere. What does the OSHA "two-in, two-out" rule require?

Answer: At least two trained firefighters must remain outside and ready to perform rescue

The two-in, two-out rule requires at least two firefighters outside in standby/rescue capacity while two operate inside an IDLH atmosphere.

What is the primary purpose of a Personal Alert Safety System (PASS) device?

Answer: To sound an alarm if a firefighter becomes motionless

A PASS device emits a loud alarm when a firefighter stops moving for a set period, helping locate a downed member.

During overhaul, why should firefighters continue wearing SCBA even after visible flames are out?

Answer: Toxic gases like carbon monoxide and hydrogen cyanide remain present

Smoldering materials release invisible toxic gases such as CO and HCN, so respiratory protection is still needed during overhaul.

What is rehabilitation ("rehab") at an emergency incident primarily designed to do?

Answer: Rest, rehydrate, and monitor firefighters to prevent injury and exhaustion

Rehab provides rest, hydration, nourishment, and medical monitoring to keep firefighters from overexertion and heat stress.

A firefighter's low-air alarm on the SCBA activates during interior operations. What is the correct action?

Answer: Immediately begin exiting to a safe area with the crew

A low-air alarm signals the firefighter should exit promptly while breathable air remains.

What does the acronym RIT (or RIC) refer to on the fireground?

Answer: A team standing by to rescue trapped or downed firefighters

A Rapid Intervention Team/Crew is dedicated to rescuing firefighters who become trapped, lost, or injured.

Why is proper hydration emphasized for firefighters even in cold weather?

Answer: Heavy PPE causes significant fluid loss regardless of outside temperature

Encapsulating turnout gear traps heat and causes sweating and dehydration even in cold conditions.
