Precision Safety and Compliance 3 — Questions and Answers
Question 1: What is the purpose of Lockout/Tagout (LOTO) procedures?
- To prevent the accidental energization of equipment during maintenance (Correct answer)
- To secure physical access doors to the facility
- To lock employee lockers during work hours
- To tag equipment that needs to be replaced
Correct answer: To prevent the accidental energization of equipment during maintenance
LOTO procedures ensure that hazardous energy sources are isolated and de-energized before employees perform maintenance or service on equipment.
Question 2: Which of the following best describes the 'hierarchy of controls' in workplace safety?
- Elimination, substitution, engineering controls, administrative controls, PPE (Correct answer)
- PPE, administrative controls, engineering controls, substitution, elimination
- Administrative controls, PPE, engineering controls, substitution, elimination
- Engineering controls, elimination, substitution, PPE, administrative controls
Correct answer: Elimination, substitution, engineering controls, administrative controls, PPE
The hierarchy of controls ranks hazard reduction strategies from most to least effective, starting with eliminating the hazard entirely and ending with PPE as the last resort.
Question 3: A confined space that contains a hazardous atmosphere or engulfment risk is classified as:
- A permit-required confined space (Correct answer)
- A standard confined space
- A restricted access zone
- A Class II confined space
Correct answer: A permit-required confined space
OSHA defines a permit-required confined space as one that has the potential to contain serious hazards, requiring a written permit before entry.
Question 4: How often must fire extinguishers in a workplace be inspected?
- Monthly visual inspection and annual maintenance (Correct answer)
- Only when a fire occurs
- Quarterly inspection and biennial maintenance
- Weekly inspection and monthly maintenance
Correct answer: Monthly visual inspection and annual maintenance
OSHA requires monthly visual inspections of fire extinguishers and annual maintenance checks by a qualified service provider.
Question 5: What does 'right-to-know' legislation primarily guarantee workers?
- Access to information about hazardous substances in their workplace (Correct answer)
- The right to refuse all overtime work
- The right to know their exact salary
- Access to coworkers' disciplinary records
Correct answer: Access to information about hazardous substances in their workplace
Right-to-know laws, reinforced by OSHA's HazCom Standard, guarantee workers access to information about hazardous chemicals they may encounter on the job.
Question 6: Which action should a worker take FIRST upon discovering a chemical spill?

- Immediately begin cleanup without protective gear to act quickly
- Call the media to report the incident
- Wait for a supervisor to arrive before taking any action
Correct answer: Alert coworkers and evacuate the area if the spill is uncontrollable
The first priority in a chemical spill is worker safety — alerting others and evacuating if the spill cannot be safely controlled prevents exposure injuries.

- 8 hours (Correct answer)
- 24 hours
- 48 hours
