CESCO Toxic Substances & Chemical Management (TSCA) 2 — Questions and Answers
Question 1: OSHA's Hazard Communication Standard (HazCom) is aligned with which internationally recognized chemical classification system?
- Globally Harmonized System (GHS) (Correct answer)
- International Chemical Registry (ICR)
- Universal Hazard Protocol (UHP)
- Chemical Abstract Service (CAS)
Correct answer: Globally Harmonized System (GHS)
OSHA's HazCom 2012 standard aligned U.S. requirements with the United Nations Globally Harmonized System (GHS) for classifying and labeling chemicals.
Question 2: Safety Data Sheets (SDS) required under HazCom must contain how many standardized sections?
- 16 (Correct answer)
- 12
- 10
- 18
Correct answer: 16
GHS-aligned SDS documents must contain exactly 16 sections covering identification, hazards, composition, first aid, firefighting, handling, storage, and other information.
Question 3: Under the EPA's Risk Management Program (RMP), facilities storing threshold quantities of regulated substances must submit an RMP plan to which agency?
- EPA (Correct answer)
- OSHA
- DHS
- DOT
Correct answer: EPA
RMP plans are submitted to the EPA under Clean Air Act Section 112(r), though OSHA's PSM standard covers the workplace safety side of the same facilities.
Question 4: The EPA's Toxic Release Inventory (TRI) program requires facilities to report annual releases of listed toxic chemicals under which law?
- EPCRA Section 313 (Correct answer)
- CERCLA Section 103
- RCRA Section 3002
- TSCA Section 8
Correct answer: EPCRA Section 313
TRI reporting is required under Section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA), with reports due July 1 each year.
Question 5: Which federal regulation governs the transportation of hazardous materials in commerce, including proper classification, packaging, and labeling?
- DOT Hazardous Materials Regulations (49 CFR Parts 100-185) (Correct answer)
- EPA RCRA Manifest System
- OSHA Process Safety Management (29 CFR 1910.119)
- TSCA Inventory Rules
Correct answer: DOT Hazardous Materials Regulations (49 CFR Parts 100-185)
The DOT Hazardous Materials Regulations (HMR) in 49 CFR Parts 100–185 govern the safe transportation of hazardous materials by all modes of transport.
Question 6: Under OSHA's Process Safety Management (PSM) standard, what is the threshold quantity of flammable liquids that triggers full PSM coverage?
- 10,000 pounds (Correct answer)
- 5,000 pounds
- 1,000 pounds
- 25,000 pounds
Correct answer: 10,000 pounds
OSHA PSM (29 CFR 1910.119) applies to flammable liquids and gases at or above 10,000 pounds threshold quantity when stored above their normal boiling point.
