ACS CP ACS CP Chemical Regulations & Compliance 1 — Questions and Answers
Question 1: Under TSCA (Toxic Substances Control Act), which section requires chemical manufacturers to notify EPA before manufacturing or importing a new chemical substance?
- Section 4 - Testing Requirements
- Section 5 - Manufacturing and Processing Notices (PMN) (Correct answer)
- Section 6 - Regulation of Hazardous Chemical Substances
- Section 8 - Reporting and Record-keeping
Correct answer: Section 5 - Manufacturing and Processing Notices (PMN)
TSCA Section 5 requires submission of a Pre-Manufacture Notice (PMN) to EPA at least 90 days before a new chemical substance is manufactured or imported in the US.
Question 2: The GHS (Globally Harmonized System) hazard communication standard uses how many signal words on labels?
- One (either 'Danger' or 'Warning') (Correct answer)
- Three ('Danger,' 'Warning,' 'Caution')
- Four ('Extreme,' 'High,' 'Moderate,' 'Low')
- Two ('Hazardous' and 'Not Hazardous')
Correct answer: One (either 'Danger' or 'Warning')
GHS uses only two signal words: 'Danger' for more severe hazards and 'Warning' for less severe hazards — never both on the same label.
Question 3: EPA's Risk Management Program (RMP) under Clean Air Act Section 112(r) requires facilities to:
- Obtain permits for all air emissions above de minimis thresholds
- Develop and submit a risk management plan for processes with regulated substances above threshold quantities (Correct answer)
- Install continuous emission monitoring systems on all process vents
- Register all hazardous chemicals with the National Response Center
Correct answer: Develop and submit a risk management plan for processes with regulated substances above threshold quantities
RMP requires facilities with regulated substances above threshold quantities to develop an accident prevention program and submit a Risk Management Plan to the EPA.
Question 4: REACH regulation (Registration, Evaluation, Authorisation and Restriction of Chemicals) is enforced in:
- United States only
- European Union member states (Correct answer)
- All UN member nations
- OECD member countries
Correct answer: European Union member states
REACH is the primary EU chemicals regulation that requires registration of chemical substances manufactured or imported into the EU in quantities ≥1 tonne/year with ECHA.
Question 5: In the US, the Hazard Communication Standard (HazCom 2012) aligned with GHS requires SDS to have how many sections?
- 8 sections
- 12 sections
- 16 sections (Correct answer)
- 24 sections
Correct answer: 16 sections
HazCom 2012 (aligned with GHS) requires Safety Data Sheets to follow the 16-section format standardized by OSHA, replacing the former variable MSDS format.
Question 6: The DOT hazardous materials placard system identifies the hazard class of a shipment using:
- EPA waste codes (D, F, K, P, U series)
- UN hazard class numbers (1-9) displayed on diamond-shaped placards (Correct answer)
- NFPA 704 diamond ratings for health, flammability, reactivity
- CAS registry numbers printed on the transport vehicle
Correct answer: UN hazard class numbers (1-9) displayed on diamond-shaped placards
DOT uses diamond-shaped placards displaying UN hazard class numbers (1=explosives through 9=miscellaneous) and UN identification numbers to communicate hazards during transport.
