CHMM Occupational Health And Safety 2 — Questions and Answers
Question 1: Under OSHA's Hazard Communication Standard (HazCom 2012), how many sections must a Safety Data Sheet contain?
- 12 sections
- 16 sections (Correct answer)
- 10 sections
- 18 sections
Correct answer: 16 sections
GHS-aligned SDSs must contain exactly 16 sections covering hazard identification, composition, first aid, firefighting, handling, and more.
Question 2: Which OSHA standard specifically governs employee exposure to bloodborne pathogens in the workplace?
- 29 CFR 1910.120
- 29 CFR 1910.1030 (Correct answer)
- 29 CFR 1910.134
- 29 CFR 1910.146
Correct answer: 29 CFR 1910.1030
29 CFR 1910.1030 is OSHA's Bloodborne Pathogens Standard, requiring exposure control plans, PPE, and hepatitis B vaccination offers.
Question 3: A worker is exposed to a chemical at 200 ppm for 4 hours and 100 ppm for 4 hours. Using TWA calculation, what is the 8-hour TWA?
- 150 ppm (Correct answer)
- 175 ppm
- 300 ppm
- 100 ppm
Correct answer: 150 ppm
TWA = (200×4 + 100×4) / 8 = (800+400)/8 = 150 ppm.
Question 4: Which type of air-purifying respirator is MOST appropriate for protection against organic vapors at concentrations below IDLH?
- HEPA filter respirator
- Powered air-purifying respirator with P100 filters
- Half-face respirator with OV cartridges (Correct answer)
- Supplied-air respirator
Correct answer: Half-face respirator with OV cartridges
A half-face air-purifying respirator with organic vapor (OV) cartridges is designed specifically to adsorb organic vapor contaminants below IDLH levels.
Question 5: Under OSHA's Process Safety Management (PSM) standard, what is the threshold quantity for flammable liquids and gases that triggers coverage?
- 5,000 lbs
- 10,000 lbs (Correct answer)
- 15,000 lbs
- 25,000 lbs
Correct answer: 10,000 lbs
29 CFR 1910.119 sets the threshold quantity for flammable liquids and gases at 10,000 lbs for PSM applicability.
Question 6: What does the term 'permissible exposure limit' (PEL) represent under OSHA regulations?
- A recommended advisory guideline with no legal force
- The legally enforceable maximum airborne concentration for an 8-hour workday (Correct answer)
- The concentration immediately dangerous to life and health
- A short-term exposure limit for 15-minute exposures
Correct answer: The legally enforceable maximum airborne concentration for an 8-hour workday
PELs are legally enforceable OSHA standards specifying the maximum allowable airborne chemical concentration during an 8-hour workday.
Question 7: Which medical surveillance requirement applies to workers regularly exposed to inorganic lead above the action level?
- Annual chest X-ray and pulmonary function test
- Blood lead level (BLL) monitoring and biological exposure index testing (Correct answer)
- Urinalysis and liver enzyme panels quarterly
- Audiometric testing and vision screening
Correct answer: Blood lead level (BLL) monitoring and biological exposure index testing
OSHA's lead standard (29 CFR 1910.1025) requires blood lead level monitoring and medical removal protection when BLLs exceed trigger thresholds.
