WALMART MAINTENANCE Safety and Compliance 5 — Questions and Answers
Question 1: Under OSHA's fall protection standard, at what height above a lower level must maintenance workers use fall protection in general industry?
- 4 feet (Correct answer)
- 6 feet
- 8 feet
- 10 feet
Correct answer: 4 feet
OSHA's general industry standard (29 CFR 1910.23) requires fall protection when workers are exposed to fall hazards of 4 feet or more.
Question 2: A maintenance team discovers a chemical spill of an unknown substance. What is the FIRST step?
- Begin cleanup using available rags
- Identify the substance using the SDS before taking any action
- Evacuate the area and call hazmat or a qualified responder (Correct answer)
- Dilute the spill with water immediately
Correct answer: Evacuate the area and call hazmat or a qualified responder
An unknown chemical spill requires immediate area evacuation and notification of a qualified hazmat responder before any cleanup attempt.
Question 3: Which of the following best describes the purpose of a job hazard analysis (JHA)?
- To document completed maintenance tasks
- To identify and mitigate hazards before starting a job (Correct answer)
- To assign blame after an incident
- To calculate the cost of safety equipment
Correct answer: To identify and mitigate hazards before starting a job
A JHA is a proactive process that breaks a job into steps, identifies hazards at each step, and determines controls to eliminate or reduce those hazards.
Question 4: What is the correct response if a maintenance employee is exposed to a bloodborne pathogen (e.g., from a needlestick)?
- Wash the wound, report immediately, and seek medical evaluation (Correct answer)
- Apply a bandage and continue working
- Fill out an incident report at end of shift
- Disinfect with bleach and monitor symptoms at home
Correct answer: Wash the wound, report immediately, and seek medical evaluation
Immediate wound washing, prompt reporting, and medical evaluation (which may include post-exposure prophylaxis) are required under OSHA's Bloodborne Pathogen Standard.
Question 5: Which of the following actions violates proper scaffold safety during a maintenance repair at height?
- Using a guardrail on all open sides
- Standing on a plank that overhangs the end support by 14 inches (Correct answer)
- Tying off the scaffold to the building structure
- Inspecting the scaffold before each work shift
Correct answer: Standing on a plank that overhangs the end support by 14 inches
Planks should overhang end supports by no more than 12 inches to prevent tipping; a 14-inch overhang exceeds OSHA's safe limit.
Question 6: Walmart's maintenance compliance requires that refrigerant handling comply with which federal regulation?
- OSHA 29 CFR 1910.119
- EPA Section 608 of the Clean Air Act (Correct answer)
- NFPA 72
- DOT 49 CFR Part 173
Correct answer: EPA Section 608 of the Clean Air Act
EPA Section 608 prohibits venting refrigerants and requires certified technicians to recover, recycle, or reclaim refrigerants during service or disposal.
Question 7: If a fire extinguisher in the maintenance shop shows a pressure gauge in the red (low) zone, the correct action is to:
- Shake the extinguisher to redistribute the agent
- Tag it out of service and replace or recharge it immediately (Correct answer)
- Use it anyway since it may still have partial charge
- Report it at the next weekly safety meeting
Correct answer: Tag it out of service and replace or recharge it immediately
A fire extinguisher with a gauge in the red zone is undercharged and unreliable; it must be removed from service and replaced or recharged before further use.
