According to the Iceberg Theory of accident costs, if a construction company spends $10,000 on direct medical costs and compensation for an injured worker, what is the most likely impact on the company's indirect costs?
Indirect costs will be roughly equal to the direct costs.
Indirect costs will likely far exceed the direct costs.
Indirect costs are negligible and usually covered by insurance.
Indirect costs only apply if the equipment was damaged.
A worker removes a machine guard to speed up a cutting process because the deadline is approaching. According to the Domino Theory of Accident Causation, this specific action represents:

Management claims that safety slows down production. Based on OSH principles regarding efficiency and morale, what is the strongest counter-argument?
Safety allows workers to take more breaks.
A safe workplace reduces lost time claims and improves overall workforce efficiency and quality output.
Safety is required by law, so productivity is secondary.
Safety equipment makes workers look more professional.
A mobile crane is set up on a construction site. To ensure maximum stability before lifting a load, what is the critical requirement regarding the outriggers?
They must be extended at least 50%.
They must be fully extended and set upon firm, level ground.
They are optional if the load is light.
They should be placed on wooden blocks regardless of ground condition.
A rigger is preparing to lift a heavy steel beam. He notices the load is not centered under the hook. If he proceeds with the lift, what is the immediate physical consequence?
The crane will immediately overturn.
The load will swing to center itself under the lift point when suspended, potentially striking workers.
The hoist line will snap immediately.
The load will remain stationary but the motor will overheat.
During a crane operation, the signalman loses radio contact with the operator. What is the correct and immediate procedure?
The operator should continue the lift if they have a clear line of sight.
The signalman should run toward the cab to shout instructions.
All operations must stop until communication is re-established.
The operator should switch to autonomous mode.
You are inspecting a wire rope sling and notice several wires are broken. According to standard rejection criteria, when must the rope be removed from service?

When the manufacturer's tag is slightly faded but legible.
Why is the "Absolute Limit of Approach" critical when operating cranes near power lines?

Guardrails are optional if workers are skilled.
A worker is using a fall arrest system. He attaches his lanyard to a PVC electrical conduit pipe running along the ceiling. Why is this unsafe?
The pipe might scratch the lanyard hook.
Electrical conduits are not structural members and cannot support the force of a fall (approx. 5000 lbs).
The lanyard is too short for ceiling attachment.
The pipe is slippery.
When using a full-body harness, why is the shock-absorbing lanyard critical?
It allows the worker to bounce back up after a fall.
It extends the reach of the worker.
It reduces the arresting force on the worker's body during a fall.
It acts as a retrieval rope for rescue.
A scaffold is being erected. To ensure the stability of the platform boards, how much should the wood planks extend beyond the end supports?
They should be flush with the support.
They should extend at least 6 inches but not more than 12 inches (unless cleated).
They should extend 3 feet to allow for a walkway.
They do not need to extend; they should be nailed down immediately.

After the accident has occurred.
After listing the basic steps of the job.
Before selecting the job to be analyzed.
Only when the DOLE inspector arrives.
You are conducting a Risk Assessment (HIRAC). You identify a hazard with a "High" probability of occurrence and a "High" severity of injury. How should this risk be prioritized?
It can be addressed next month.
It requires immediate attention and control measures.
