CEA Jobsite Safety Procedures 5 — Questions and Answers
Question 1: Which of the following materials is considered a slip, trip, and fall hazard on a jobsite?
- Properly stored tools in a toolbox
- Electrical cords running across a walkway (Correct answer)
- A ladder leaning against a wall at a 4:1 ratio
- A properly stacked pallet of materials
Correct answer: Electrical cords running across a walkway
Electrical cords crossing walkways create tripping hazards and must be covered or routed to avoid pedestrian paths.
Question 2: What does OSHA's 'multi-employer worksite' policy mean for electrical apprentices?
- All workers on site share one employer for legal purposes
- An apprentice can be cited for hazards their employer created even if another employer's workers are exposed (Correct answer)
- Only the general contractor is responsible for safety citations
- Each employer is responsible only for hazards unique to their trade
Correct answer: An apprentice can be cited for hazards their employer created even if another employer's workers are exposed
OSHA's multi-employer policy holds creating, exposing, correcting, and controlling employers each responsible for relevant hazards on a shared worksite.
Question 3: A worker needs to use a powder-actuated tool on a jobsite. What is required before operating this tool?
- A general contractor's written approval only
- Proof of training and a valid operator card for that tool (Correct answer)
- Wearing standard safety glasses only
- Completing a toolbox talk about the specific project
Correct answer: Proof of training and a valid operator card for that tool
Powder-actuated tools require operators to be trained and carry a valid card from the manufacturer for the specific tool model.
Question 4: What is the primary purpose of weekly 'toolbox talks' or 'safety briefings' on a jobsite?
- To review production goals for the coming week
- To reinforce safety awareness and address site-specific hazards (Correct answer)
- To document which workers arrived on time
- To assign work tasks for the day
Correct answer: To reinforce safety awareness and address site-specific hazards
Toolbox talks are short, focused safety meetings that reinforce safe practices and address hazards relevant to current work activities.
Question 5: Which of the following actions violates OSHA scaffold safety regulations on a construction site?
- Installing guardrails on all open sides above 10 feet
- Climbing the cross-braces of a tubular welded frame scaffold (Correct answer)
- Using a properly rated scaffold plank rated for the load
- Inspecting the scaffold before each work shift
Correct answer: Climbing the cross-braces of a tubular welded frame scaffold
OSHA prohibits climbing scaffold cross-braces; access must be through a proper ladder, stairway, or access frame.
Question 6: What is the maximum allowable angle for a portable straight ladder when in use?
- 60 degrees from horizontal (3:1 ratio)
- 75.5 degrees from horizontal (4:1 ratio) (Correct answer)
- 80 degrees from horizontal (5:1 ratio)
- 90 degrees (straight vertical)
Correct answer: 75.5 degrees from horizontal (4:1 ratio)
OSHA requires portable ladders to be positioned at a 4:1 ratio, meaning one foot out for every four feet of height, which equals approximately 75.5 degrees.
Question 7: If a worker receives a minor cut on the jobsite, what should happen to the blood-soiled materials (rags, bandages)?
- Dispose of them in the nearest trash can
- Leave them for the jobsite cleanup crew
- Treat them as potentially infectious and dispose of them per the site's bloodborne pathogen plan (Correct answer)
- Rinse and reuse if the cut was small
Correct answer: Treat them as potentially infectious and dispose of them per the site's bloodborne pathogen plan
OSHA's Bloodborne Pathogen Standard requires that blood-soiled materials be handled and disposed of as potentially infectious waste.
