CPT Safety Awareness & Compliance 3 — Questions and Answers
Question 1: Which type of fire extinguisher is appropriate for a Class C electrical fire in a production environment?
- CO2 or dry chemical extinguisher rated for Class C fires (Correct answer)
- Water extinguisher
- Class A foam extinguisher
- Class B sand bucket
Correct answer: CO2 or dry chemical extinguisher rated for Class C fires
Class C fires involve energized electrical equipment; CO2 and dry chemical extinguishers are non-conductive and safe to use, while water conducts electricity and is dangerous.
Question 2: Under OSHA's Bloodborne Pathogens Standard (29 CFR 1910.1030), which control is considered the primary means of preventing exposure?
- Engineering and work practice controls such as sharps disposal containers and hand-washing facilities (Correct answer)
- Wearing double gloves at all times
- Annual blood testing for all employees
- Posting warning signs in affected areas
Correct answer: Engineering and work practice controls such as sharps disposal containers and hand-washing facilities
OSHA's Bloodborne Pathogens Standard prioritizes engineering controls and safe work practices as the primary exposure prevention strategy, with PPE as a secondary layer.
Question 3: What does the acronym GHS stand for in the context of chemical safety?
- Globally Harmonized System of Classification and Labelling of Chemicals (Correct answer)
- General Hazard Safety Standard
- Government Health and Safety
- Graded Hazard Scoring System
Correct answer: Globally Harmonized System of Classification and Labelling of Chemicals
GHS stands for the Globally Harmonized System of Classification and Labelling of Chemicals, adopted by OSHA through the HazCom 2012 update.
Question 4: A production worker is required to enter a confined space with limited oxygen. What type of confined space classification applies?
- Permit-required confined space (Correct answer)
- Non-permit confined space
- Restricted access zone
- Controlled environment workspace
Correct answer: Permit-required confined space
A confined space with an atmospheric hazard such as oxygen deficiency is classified as a permit-required confined space under OSHA 29 CFR 1910.146.
Question 5: What is the OSHA permissible exposure limit (PEL) framework primarily designed to protect workers from?
- Health effects from exposure to airborne contaminants over an 8-hour workday (Correct answer)
- Noise levels exceeding 100 dB at any time
- Exposure to any chemical above zero concentration
- Repetitive motion injuries in assembly operations
Correct answer: Health effects from exposure to airborne contaminants over an 8-hour workday
PELs set legal limits on the concentration of airborne substances workers may be exposed to during an 8-hour time-weighted average workday.
Question 6: An employee slips on a wet floor and nearly falls but is not injured. This event should be recorded as a:
- Near-miss incident requiring investigation and documentation (Correct answer)
- Recordable OSHA injury on the 300 log
- Minor event with no documentation needed
- First-aid case only if medical attention was sought
Correct answer: Near-miss incident requiring investigation and documentation
Near-misses must be investigated and documented to identify hazards and prevent future injuries, even though no injury occurred.
Question 7: Which fall protection method is considered an engineering control rather than an administrative control?
- Installing guardrails along an elevated work platform (Correct answer)
- Requiring workers to buddy up near fall hazards
- Posting warning signs at platform edges
- Scheduling fall-hazard work during low-traffic hours
Correct answer: Installing guardrails along an elevated work platform
Guardrails are a physical barrier (engineering control) that passively prevents falls, while administrative controls rely on changing worker behavior or procedures.
