What this exam covers
5 real sample questions
How often must portable fire extinguishers receive a more thorough maintenance check (beyond the monthly visual inspection)?
A. Every week
B. Annually
C. Every 5 years only
D. Only after use
Show answer and reasoning

Correct answer: B. Annually

  • A: A weekly interval is far more frequent than what the standard specifies for the maintenance check.
  • C: This interval corresponds to some hydrostatic testing cycles, not the annual maintenance check requirement.
  • D: Maintenance checks are required on a recurring annual basis, not only triggered by use.
Source: 29 CFR 1910.157(e)(3)
What does 29 CFR 1910.157 primarily regulate?
A. The placement, use, maintenance, and testing of portable fire extinguishers in the workplace
B. The design and installation of fixed sprinkler systems
C. The construction of fire-rated walls and doors
D. The transportation of flammable liquids on public roads
Show answer and reasoning

Correct answer: A. The placement, use, maintenance, and testing of portable fire extinguishers in the workplace

  • B: Fixed automatic sprinkler systems are addressed by a different standard, not the portable fire extinguisher rule.
  • C: Fire-rated building construction elements are not covered by this standard.
  • D: Transportation of flammable liquids falls under DOT hazardous materials regulations, not this OSHA standard.
Source: 29 CFR 1910.157(a)
An employer that develops and implements an emergency action plan requiring total and immediate evacuation of employees and does not permit any employee to fight fires is exempt from which portion of the extinguisher standard?
A. All requirements of the standard, with no exceptions whatsoever
B. All requirements except the portable fire extinguisher hydrostatic testing requirements
C. Only the training requirements, but not maintenance
D. Only the mounting and marking requirements
Show answer and reasoning

Correct answer: B. All requirements except the portable fire extinguisher hydrostatic testing requirements

  • A: The exemption is not absolute; hydrostatic testing obligations still apply if extinguishers remain in the workplace.
  • C: The exemption is broader than just training; it covers most of the standard except hydrostatic testing, not a training-only carve-out.
  • D: Mounting and marking are not the specific carve-out identified by the standard for this exemption.
Source: 29 CFR 1910.157(b)(1)
For the total-evacuation exemption in 1910.157(b) to apply, what must the employer's emergency action plan require of employees?
A. Immediate and total evacuation, with no employees expected to fight incipient stage fires
B. That all employees receive fire brigade training before evacuating
C. That only management personnel evacuate first
D. That employees fight the fire until the fire department arrives, then evacuate
Show answer and reasoning

Correct answer: A. Immediate and total evacuation, with no employees expected to fight incipient stage fires

  • B: Requiring fire brigade training for all employees contradicts a pure evacuation-only policy and is not the condition for this exemption.
  • C: A staggered evacuation order for management only does not meet the plan requirement for this exemption.
  • D: The exemption specifically requires that employees not be expected to fight fires, which contradicts fighting the fire before evacuating.
Source: 29 CFR 1910.157(b)
What is the general requirement for how portable fire extinguishers must be mounted and located in the workplace?
A. They must be mounted, located, and identified so they are readily accessible without obstruction
B. They may be stored in a locked cabinet with the key held only by the safety manager
C. They must be kept in a central storage room away from work areas to prevent tampering
D. They may be placed anywhere as long as one exists somewhere in the building
Show answer and reasoning

Correct answer: A. They must be mounted, located, and identified so they are readily accessible without obstruction

  • B: Locking extinguishers away with restricted key access defeats the readily-accessible requirement of the standard.
  • C: Centralized storage away from work areas would fail the accessibility and travel-distance requirements.
  • D: The standard requires specific accessibility and travel-distance criteria, not just any presence somewhere in the building.
