1. When placing a Lockout-Tagout (LOTO) on a system, how many locks should be applied?
a. One lock per system.
b. As many locks as there are personnel working on the system.
c. Two locks for redundancy.
d. No locks are required if a tag is used.
Answer: b
Rationale: Each worker must apply their own lock to ensure their safety while working on the system.
This prevents accidental re-energization while someone is still working.
2. A ladder must be able to support ____ times the weight of the expected load.
a. 2.5
b. 3.3
c. 4.0
d. 5.0
Answer: b
Rationale: OSHA standards require that ladders support at least 3.3 times the maximum intended load
to ensure safety.
3. It is acceptable to enter into a confined space without an attendant, but only if all other precautions
and PPE are taken.
a. True
b. False
Answer: b
Rationale: OSHA requires an attendant for confined space entry to monitor the entrant and initiate
rescue if necessary. PPE alone is not sufficient.
4. A defective air pressure gauge on the supply air of a dry pipe system is considered a _____.
,ESTUDY
a. Minor deficiency
b. Critical deficiency
c. Non-critical deficiency
d. Cosmetic issue
Answer: b
Rationale: A defective air pressure gauge can lead to improper system operation, making it a critical
deficiency that requires immediate attention.
5. When taking a sprinkler system out of service, which of the following are approved sources of a
temporary water supply?
a. A hose from a fire hydrant to the FDC.
b. A portable tank and pump.
c. A standby fire department pumper.
d. All of the above.
Answer: d
Rationale: All these options are approved temporary water supplies to maintain fire protection while
the system is impaired.
6. When using a ladder for electrical work, _______.
a. The rails must be non-conductive.
b. The ladder must be metal for durability.
c. The ladder must be painted.
d. The ladder must be grounded.
Answer: a
Rationale: Non-conductive rails prevent electrical shock when working near live electrical components.
7. When using an aerial lift, you must:
a. Tie off with a lanyard.
b. Wear a hard hat.
c. Have received appropriate training.
d. All of the above.
Answer: d
Rationale: All these precautions are required to ensure safety while operating an aerial lift.

8. When an employee may be exposed to hazardous chemicals, when must training be given?
a. When they might be exposed to said chemical.
b. When new chemicals have been added to the workplace.
c. Both a and b.
d. Only during initial hiring.
Answer: c
Rationale: OSHA requires training both when exposure is possible and when new chemicals are
introduced to the workplace.
9. Toxic chemicals will be hazardous in a confined space when the ______ is exceeded.
a. LEL (Lower Explosive Limit)
b. PEL (Permissible Exposure Limit)
c. UEL (Upper Explosive Limit)
d. IDLH (Immediately Dangerous to Life or Health)
Answer: b
Rationale: The PEL is the maximum allowable concentration of a toxic substance in the air, as defined by
OSHA.
10. A hydropneumatic pump is used to check for air leaks on a dry pipe system.
a. True
b. False
Answer: b
Rationale: A hydropneumatic pump is used to pressurize the system, but air leaks are typically checked
using an air compressor and monitoring the pressure drop.
11. When shutting down a system for impairment, you must hang a tag at _______.
a. The system control valve only.
b. The FDC only.
c. Both the system control valve and the FDC.
d. The nearest fire alarm panel.
, ESTUDY
Answer: c
Rationale: Tags must be placed at both the system control valve and the FDC to ensure all personnel are
aware of the impairment.
12. Prior to entering a confined space, oxygen must be tested to be between ______.
a. 18% and 22%
b. 19.5% and 23.5%
c. 20% and 25%
d. 21% and 24%
Answer: b
Rationale: OSHA defines safe oxygen levels as between 19.5% and 23.5% for confined space entry.
13. Before opening a fire pump controller and measuring voltage and amps, you must be trained in
______.
a. NFPA 70E, arc flash, and the proper PPE.
b. Basic electrical theory.
c. Fire pump operation only.
d. None of the above.
Answer: a
Rationale: NFPA 70E training is required to safely work on electrical equipment, including understanding
arc flash hazards and proper PPE.
14. When testing antifreeze solutions, what tools are recommended?
a. Refractometer or hydrometer.
b. Thermometer only.
c. Pressure gauge.
d. pH meter.
Answer: a
Rationale: A refractometer or hydrometer is used to measure the concentration of antifreeze solutions
accurately.
