ITMC Safety Procedures 2 — Questions and Answers
Question 1: When performing maintenance on a hydraulic system under pressure, what must be done FIRST?
- Begin work immediately while pressure is manageable
- Depressurize and bleed the system before touching any components (Correct answer)
- Wear double gloves and proceed carefully
- Only depressurize if pressure exceeds 3000 PSI
Correct answer: Depressurize and bleed the system before touching any components
Hydraulic systems must be fully depressurized and bled before any maintenance to prevent injection injuries from high-pressure fluid.
Question 2: What does the hierarchy of hazard controls rank as the MOST effective method?
- Administrative controls
- Personal protective equipment
- Engineering controls
- Elimination of the hazard (Correct answer)
Correct answer: Elimination of the hazard
Elimination — physically removing the hazard — is ranked highest in the hierarchy because it completely removes the risk.
Question 3: A technician notices a frayed electrical cord on a piece of production equipment. The correct action is to:
- Wrap it with electrical tape and continue operations
- Tag it out and report it for repair before use (Correct answer)
- Cover it with a rubber mat to protect workers walking by
- Unplug the cord and leave the equipment unplugged without documentation
Correct answer: Tag it out and report it for repair before use
Frayed cords must be tagged out of service and reported for proper repair to prevent shock or fire hazards.
Question 4: Which class of fire extinguisher is appropriate for a fire involving energized electrical equipment?
- Class A
- Class B
- Class C (Correct answer)
- Class D
Correct answer: Class C
Class C extinguishers use non-conductive agents specifically rated for fires involving energized electrical equipment.
Question 5: What is the purpose of a Job Hazard Analysis (JHA) before beginning a maintenance task?
- To assign blame if an accident occurs
- To identify and control hazards associated with each step of the job (Correct answer)
- To document the time required to complete the task
- To satisfy insurance requirements only
Correct answer: To identify and control hazards associated with each step of the job
A JHA systematically identifies hazards in each job step so appropriate controls can be implemented before work begins.
Question 6: When working at heights above 4 feet in a general industry setting, OSHA requires:
- A spotter to watch from below
- Fall protection such as guardrails, safety nets, or personal fall arrest systems (Correct answer)
- Hard hats only
- No specific requirement unless height exceeds 10 feet
Correct answer: Fall protection such as guardrails, safety nets, or personal fall arrest systems
OSHA's general industry standard (29 CFR 1910) requires fall protection at elevations of 4 feet or more.
Question 7: A Safety Data Sheet (SDS) Section 8 provides information about:
- Physical and chemical properties of the substance
- Exposure controls and personal protective equipment requirements (Correct answer)
- First aid measures after exposure
- Regulatory information and classifications
Correct answer: Exposure controls and personal protective equipment requirements
SDS Section 8 covers exposure limits, engineering controls, and PPE requirements for safely handling the chemical.
