Question 1
When placing a lockout/tagout (LOTO) on a system, how many locks should be
applied?
• A) One lock per shift
• B) As many locks as there are personnel working on the system
• C) One lock per system
• D) Two locks per crew member
Rationale: LOTO requires each individual working on the system to apply their own
personal lock to ensure the system cannot be re-energized while any worker remains in
a hazardous area.
Question 2
A ladder used for electrical work must have which characteristic?
, • A) Aluminum construction for durability
• B) Non-conductive rails
• C) Steel-reinforced rungs
• D) Rubber feet only
Rationale: When using a ladder for electrical work, the rails must be non-conductive to
prevent electrocution hazards.
Question 3
A ladder must be able to support how many times the weight of the expected
load?
• A) 2.0 times
• B) 3.0 times
• C) 3.3 times
• D) 4.0 times
Rationale: Ladders must be rated to support 3.3 times the expected load weight for
safety margins.
Question 4
It is acceptable to enter a confined space without an attendant, provided all other
precautions and PPE are taken.
• A) True
• B) False
,Rationale: A confined space entry ALWAYS requires an attendant outside the space,
regardless of other precautions taken.
Question 5

• A) Only upon initial hiring
• B) Only when new chemicals are introduced
• C) When they might be exposed to the chemical OR when new chemicals
have been added to the workplace
• D) Annually regardless of exposure
Rationale: Training must be provided whenever an employee may be exposed to a
hazardous chemical AND when new hazardous chemicals are introduced to the
workplace.
Question 6
Toxic chemicals are hazardous in a confined space when which limit is exceeded?
• A) IDLH (Immediately Dangerous to Life or Health)
• B) PEL (Permissible Exposure Limit)
• C) TLV (Threshold Limit Value)
• D) STEL (Short-Term Exposure Limit)
Rationale: The Permissible Exposure Limit (PEL) is the regulatory standard; exceeding
PEL indicates a hazardous condition in confined spaces.
, Question 7
When using an aerial lift, which of the following are required?
• A) Tie off with a lanyard
• B) Wear a hard hat
• C) Have received appropriate training
• D) All of the above
Rationale: All three safety requirements—tie-off with lanyard, hard hat, and proper
training—are mandatory when operating an aerial lift.
Question 8
A defective air pressure gauge on the supply air of a dry pipe system is classified
as:
• A) Critical deficiency
• B) Non-critical deficiency
• C) Impaired system
• D) Minor observation
Rationale: A defective air pressure gauge on a dry pipe system's supply air is
considered a critical deficiency because it prevents proper monitoring of system
pressure.
