EMP Health & Safety Protocols 2 — Questions and Answers
Question 1: Under OSHA's Lockout/Tagout (LOTO) standard, which step must be performed FIRST before applying lockout devices to energy-isolating equipment?
- Apply the lockout device
- Notify affected employees
- Release stored residual energy
- Identify all energy sources (Correct answer)
Correct answer: Identify all energy sources
OSHA 1910.147 requires identifying all hazardous energy sources before any isolation or lockout devices are applied.
Question 2: Which NFPA standard specifically governs electrical safety in the workplace and defines Arc Flash boundaries?
- NFPA 101
- NFPA 70E (Correct answer)
- NFPA 72
- NFPA 13
Correct answer: NFPA 70E
NFPA 70E, Standard for Electrical Safety in the Workplace, establishes arc flash boundaries and PPE requirements.
Question 3: An energy manager discovers that a boiler room lacks a clearly marked emergency shutoff. This is primarily a violation of which safety principle?
- Hierarchy of controls
- Emergency action planning (Correct answer)
- Housekeeping standards
- Permit-required confined space rules
Correct answer: Emergency action planning
OSHA's Emergency Action Plan requirements (29 CFR 1910.38) mandate clearly identified emergency shutoffs for energy systems.
Question 4: What is the primary purpose of a Job Hazard Analysis (JHA) in energy management operations?
- Calculate energy cost savings
- Document equipment maintenance schedules
- Identify and mitigate task-specific hazards before work begins (Correct answer)
- Establish baseline energy consumption data
Correct answer: Identify and mitigate task-specific hazards before work begins
A JHA systematically identifies hazards associated with each step of a task so controls can be implemented before the work starts.
Question 5: Which PPE category is required when working within the Arc Flash Boundary but outside the Restricted Approach Boundary?
- Category 1 (4 cal/cm²) (Correct answer)
- Category 2 (8 cal/cm²)
- Category 3 (25 cal/cm²)
- Category 4 (40 cal/cm²)
Correct answer: Category 1 (4 cal/cm²)
Category 1 PPE with minimum 4 cal/cm² arc rating is required for work within the Arc Flash Boundary at lower incident energy levels.
Question 6: When conducting a compressed gas cylinder inspection in a mechanical room, which defect would immediately require removing the cylinder from service?
- Minor surface rust on the body
- Cylinder stored without a cap
- A bulge or dent in the cylinder wall (Correct answer)
- Label showing last inspection was 2 years ago
Correct answer: A bulge or dent in the cylinder wall
Physical deformation such as bulges or dents indicates structural compromise, making the cylinder an imminent explosion hazard.
Question 7: In a permit-required confined space entry for inspecting a large HVAC duct, who holds ultimate authority to cancel the entry permit if conditions change?
- The entrant inside the space
- The entry supervisor (Correct answer)
- The attendant stationed outside
- The facility safety officer
Correct answer: The entry supervisor
Under OSHA 29 CFR 1910.146, the entry supervisor has the authority and responsibility to cancel the permit if conditions become unsafe.
