Worked questions

2. A worker is seriously injured. What should company management do?

  • ARestart work before controlling the hazard
  • BBlame the worker without investigation
  • CAlter records before reporting
  • Report and correct the hazard

Why D is correct

Emergency care and ongoing hazard control are immediate priorities. Timely regulatory reporting and a fact-based root-cause investigation support prevention and compliance.

3. What should an emergency action plan establish before an incident?

  • AOnly equipment paint colors
  • BNo worker communication
  • COnly project profit targets
  • Alarms, evacuation, accountability, roles, and contacts

Why D is correct

Workers need clear actions for fire, medical, chemical, structural, and other emergencies. Planning and drills reduce confusion and support timely rescue and accountability.

4. When should an active trench receive competent-person inspection?

  • At required intervals and after events that could increase hazards
  • BOnly after collapse
  • COnly when the owner visits
  • DNever if soil looked stable on day one

Why A is correct

Rain, vibration, loading, utilities, and changing soil can rapidly alter trench safety. Required inspections and prompt correction must track actual conditions.

5. A solvent arrives with no readable label or safety data sheet, and employees have not been trained on it. What must occur before use?

  • Obtain hazard information, label it, and train exposed workers
  • BRemove the product label
  • CMix it with another chemical
  • DUse smell to determine safety

Why A is correct

The best answer is: Obtain hazard information, label it, and train exposed workers. Hazard communication provides identity, exposure, PPE, storage, incompatibility, spill, and first-aid information before workers handle a product. The new fact pattern changes the setting, not the governing rule or management control. The other choices either skip a required step, apply a different rule, or fail to address the stated risk.

6. After heavy rain, an excavation resumes without a competent person examining soil, water, access, and protective systems. What safety step was required?

  • AOnly after collapse
  • BOnly when the owner visits
  • At required intervals and after events that could increase hazards
  • DNever if soil looked stable on day one

Why C is correct

The best answer is: At required intervals and after events that could increase hazards. Rain, vibration, loading, utilities, and changing soil can rapidly alter trench safety. Required inspections and prompt correction must track actual conditions. The new fact pattern changes the setting, not the governing rule or management control. The other choices either skip a required step, apply a different rule, or fail to address the stated risk.

  • A new chemical arrives without a safety data sheet or worker instruction. What should happen before use?
  • A supervisor discovers an imminent fall hazard. What should occur first?
  • A task is moved near a roof edge after the daily plan. What should occur?
  • A worker must enter equipment believed de-energized. What confirms the safe condition?
  • A worker presses STOP before entering guarded machinery. Is that sufficient?
  • A worker shows confusion and collapse during hot work. What is the priority?
  • How should required personal protective equipment be selected?
  • Is PPE the only control an employer should consider for a serious hazard?
  • May a general contractor assume subcontractors alone are responsible for every site hazard?
  • What is the purpose of an Injury and Illness Prevention Program?
  • When should employees receive safety instruction?
  • Workers need respirators for a hazardous exposure. Is handing out disposable masks sufficient?
  • A contractor has verbal safety rules but no assigned responsibilities, inspection process, correction tracking, or training records. Which required program is deficient?
  • A disconnect is open, but a worker does not lock out sources or test for voltage before touching conductors. What establishes a safe de-energized condition?
  • A machine operator presses the normal stop button and reaches past a guard while stored pneumatic energy remains. Is pressing STOP sufficient protection?

  • A superintendent sees an employee working beside an unprotected opening that presents imminent fall exposure. What is the first response?
  • An employee suffers a qualifying serious injury at a jobsite. Beyond emergency care, what employer actions are required?
  • During high-heat work, an employee becomes confused and collapses. What action takes priority over routine cooling breaks?
  • Employees face airborne exposure requiring respirators, but the employer supplies dust masks without evaluation, fit testing, or medical clearance. Is that enough?
  • On a multiemployer site, a general contractor knows about an exposed opening but assumes only the affected subcontractor has duties. Is that assumption sound?
  • The company buys identical gloves and eye protection for every task without assessing exposure or fit. How should PPE be selected?
  • The daily plan covered interior work, but the crew is reassigned beside an open roof edge. What must happen before the new task begins?
