CHMM Health and Safety Management 2 — Questions and Answers
Question 1: Under OSHA's Hazard Communication Standard (HazCom 2012), which section of a Safety Data Sheet (SDS) describes first-aid measures?
- Section 4 (Correct answer)
- Section 6
- Section 8
- Section 11
Correct answer: Section 4
SDS Section 4 is designated for first-aid measures under the GHS-aligned HazCom 2012 standard.
Question 2: A facility stores 15,000 lbs of a listed toxic substance above its EPCRA Section 302 threshold. Which action is required annually?
- Submit a Tier II emergency and hazardous chemical inventory report (Correct answer)
- File a RCRA Biennial Report
- Conduct an OSHA Process Safety Management audit
- Submit a TRI Form R report only
Correct answer: Submit a Tier II emergency and hazardous chemical inventory report
EPCRA Section 312 requires facilities exceeding threshold planning quantities to submit annual Tier II inventory reports to LEPC, SERC, and local fire department.
Question 3: Which industrial hygiene control hierarchy level is considered the MOST effective for reducing worker exposure to hazardous substances?
- Elimination (Correct answer)
- Engineering controls
- Administrative controls
- Personal protective equipment
Correct answer: Elimination
Elimination removes the hazard entirely and is the most effective control at the top of the hierarchy.
Question 4: An employee receives a whole-body radiation dose of 5 rem in a single calendar year from occupational exposure. This is:
- At the NRC annual occupational dose limit for whole-body exposure (Correct answer)
- Below the NRC limit but above the ALARA goal
- Above the NRC limit requiring immediate investigation
- An acceptable dose with no recordkeeping required
Correct answer: At the NRC annual occupational dose limit for whole-body exposure
NRC regulations (10 CFR 20) set the annual occupational whole-body dose limit at 5 rem (50 mSv), so 5 rem is exactly at the regulatory limit.
Question 5: When selecting respiratory protection for an IDLH atmosphere of unknown composition, which respirator is required by OSHA?
- Self-contained breathing apparatus (SCBA) in pressure-demand mode (Correct answer)
- Air-purifying respirator with combination cartridges
- Supplied-air respirator in continuous-flow mode
- Powered air-purifying respirator (PAPR) with P100 filters
Correct answer: Self-contained breathing apparatus (SCBA) in pressure-demand mode
OSHA 29 CFR 1910.134 mandates pressure-demand SCBA for IDLH atmospheres of unknown composition due to unknown contaminants.
Question 6: The Permissible Exposure Limit (PEL) for a substance is listed as a ceiling value. This means workers:
- Must never be exposed above that concentration at any time (Correct answer)
- May be exposed above that level for short excursion periods
- Are limited to an 8-hour time-weighted average at that level
- Can average exposures over a 15-minute sampling period
Correct answer: Must never be exposed above that concentration at any time
A ceiling PEL is an absolute concentration that must not be exceeded at any moment during the work shift.
Question 7: Which OSHA standard requires employers to develop and implement an Exposure Control Plan for bloodborne pathogens?
- 29 CFR 1910.1030 (Correct answer)
- 29 CFR 1910.119
- 29 CFR 1910.120
- 29 CFR 1910.1000
Correct answer: 29 CFR 1910.1030
29 CFR 1910.1030 (Bloodborne Pathogens standard) requires a written Exposure Control Plan to eliminate or minimize employee exposure.
