SSP Occupational Health & Hazard Control 5 — Questions and Answers
Question 1: Under OSHA's Hazard Communication Standard, which label element communicates the relative severity of a hazard using a pictogram with a diamond shape?
- Signal word
- GHS hazard pictogram (Correct answer)
- Precautionary statement
- Product identifier
Correct answer: GHS hazard pictogram
GHS hazard pictograms are standardized symbols within a red diamond border that communicate specific physical, health, or environmental hazards.
Question 2: A safety practitioner discovers a worker using a respirator that has never been fit-tested. Under OSHA 29 CFR 1910.134, what must the employer do before the worker uses the respirator again?
- Issue a written waiver documenting the oversight
- Conduct fit testing with the specific respirator model the worker will use (Correct answer)
- Upgrade the worker to a supplied-air respirator to avoid fit-test requirements
- Provide refresher training and allow continued use
Correct answer: Conduct fit testing with the specific respirator model the worker will use
OSHA requires fit testing with the specific make, model, and size of tight-fitting respirator the employee will wear before initial use.
Question 3: Which OSHA recordkeeping form is used to record the summary of work-related injuries and illnesses that must be posted annually?
- OSHA Form 300
- OSHA Form 300A (Correct answer)
- OSHA Form 301
- OSHA Form 302
Correct answer: OSHA Form 300A
OSHA Form 300A is the Summary of Work-Related Injuries and Illnesses that must be posted from February 1 through April 30 each year.
Question 4: What is the recommended action when an oxygen-deficient atmosphere (below 19.5% O2) is detected in a confined space?
- Increase ventilation and re-test before entry
- Enter immediately with a supplied-air respirator
- Do not enter; evacuate area and contact confined space rescue team (Correct answer)
- Use an air-purifying respirator rated for oxygen deficiency
Correct answer: Do not enter; evacuate area and contact confined space rescue team
An oxygen-deficient atmosphere is immediately dangerous to life and requires non-entry until the atmosphere is made safe or proper supplied-air and rescue support is in place.
Question 5: Which term describes the ability of a chemical to cause cancer in humans or animals?
- Teratogenicity
- Mutagenicity
- Carcinogenicity (Correct answer)
- Neurotoxicity
Correct answer: Carcinogenicity
Carcinogenicity refers to a substance's ability to initiate or promote cancer development in living tissue.
Question 6: During a workplace inspection, a safety practitioner observes workers stacking materials against an emergency exit door. Under OSHA 29 CFR 1910.37, this is a violation because:
- Exit routes must be at least 10 feet wide at all times
- Exit routes must remain unobstructed and free of materials at all times (Correct answer)
- Emergency exits must open outward and cannot be blocked from the inside
- Stacked materials create a tripping hazard under the general duty clause only
Correct answer: Exit routes must remain unobstructed and free of materials at all times
OSHA 29 CFR 1910.37 requires exit routes to be kept free of obstructions and properly maintained to allow swift egress during an emergency.
Question 7: A facilities manager wants to reduce employee exposure to silica dust during concrete cutting. Ordering the contractors to use wet methods represents which level of the hierarchy of controls?
- Elimination
- Substitution
- Engineering controls (Correct answer)
- Administrative controls
Correct answer: Engineering controls
Wet methods suppress airborne dust at the source using water, which is an engineering control that modifies the work environment to reduce exposure.
