CWLP Safety Procedures 4 — Questions and Answers
Question 1: What is the purpose of a Job Hazard Analysis (JHA) in warehouse operations?
- To calculate the cost of employee benefits
- To identify, assess, and control hazards associated with specific job tasks (Correct answer)
- To schedule preventive maintenance on equipment
- To document employee performance reviews
Correct answer: To identify, assess, and control hazards associated with specific job tasks
A JHA systematically breaks down a job into steps, identifies hazards at each step, and establishes controls to eliminate or reduce those hazards.
Question 2: A warehouse uses ammonia-based refrigeration systems. Workers must be trained on which type of emergency response plan?
- HAZWOPER 8-hour refresher only
- Process Safety Management (PSM) and Emergency Action Plan procedures (Correct answer)
- Standard first aid and CPR only
- General fire prevention plan training
Correct answer: Process Safety Management (PSM) and Emergency Action Plan procedures
Ammonia is a highly hazardous chemical subject to OSHA's PSM standard (29 CFR 1910.119), requiring specific emergency response plans and worker training.
Question 3: What is the minimum aisle width required by OSHA for powered industrial truck traffic in warehouse aisles?
- At least 1 foot wider than the widest load being moved
- At least 3 feet wider than the widest vehicle or load (Correct answer)
- Exactly 8 feet regardless of vehicle size
- No minimum — determined by the warehouse layout
Correct answer: At least 3 feet wider than the widest vehicle or load
OSHA 29 CFR 1910.178(e) requires aisles used by powered industrial trucks to be at least 3 feet wider than the largest equipment or load.
Question 4: What does 'MSDS' stand for in older warehouse safety documentation, and what replaced it?
- Material Safety Data Sheet, replaced by Safety Data Sheet (SDS) under GHS (Correct answer)
- Management Safety Documentation System, replaced by incident reports
- Mechanical System Design Specification, replaced by equipment manuals
- Multi-Site Distribution Standard, replaced by ISO 9001
Correct answer: Material Safety Data Sheet, replaced by Safety Data Sheet (SDS) under GHS
MSDS (Material Safety Data Sheet) was replaced by SDS (Safety Data Sheet) when OSHA aligned with the Globally Harmonized System (GHS) in 2012.
Question 5: Which condition would make it UNSAFE to use a metal storage rack in a warehouse?
- The rack is painted a non-standard color
- A vertical upright shows a visible bend or impact damage (Correct answer)
- The rack holds mixed SKUs on the same level
- The manufacturer's label is partially worn
Correct answer: A vertical upright shows a visible bend or impact damage
Bent or impact-damaged uprights compromise the structural integrity of the entire rack system and must be removed from service immediately.
Question 6: In the context of warehouse safety, what is the HIERARCHY OF CONTROLS, listed from most to least effective?
- PPE → Administrative controls → Engineering controls → Substitution → Elimination
- Elimination → Substitution → Engineering controls → Administrative controls → PPE (Correct answer)
- Administrative controls → PPE → Engineering controls → Elimination → Substitution
- Substitution → PPE → Elimination → Administrative controls → Engineering controls
Correct answer: Elimination → Substitution → Engineering controls → Administrative controls → PPE
The hierarchy runs from elimination (most effective, removes the hazard) through substitution, engineering controls, administrative controls, to PPE (least effective alone).
Question 7: A dock leveler is found to be stuck in the raised position with a trailer still at the dock. What is the correct procedure?
- Manually push the leveler down using a forklift
- Tag the dock out of service and notify maintenance before any truck loading/unloading (Correct answer)
- Unload the trailer quickly before the leveler fails completely
- Have workers jump between the trailer and dock floor
Correct answer: Tag the dock out of service and notify maintenance before any truck loading/unloading
A malfunctioning dock leveler is a serious fall and crush hazard — the dock must be taken out of service and repaired before operations resume.
