Under OSHA's Hazard Communication Standard (29 CFR 1910.1200), how many sections must a GHS-compliant Safety Data Sheet (SDS) contain?
Answer: 16
GHS-aligned SDSs are standardized to exactly 16 sections, covering everything from chemical identification through disposal considerations.
On an NFPA 704 diamond, the red quadrant communicates which type of hazard?
Answer: Flammability hazard
In the NFPA 704 system, red = flammability, blue = health, yellow = reactivity, and white = special notices.
Under RCRA, a facility generating between 100 and 1,000 kg of hazardous waste per month is classified as a:
Answer: Small Quantity Generator
Small Quantity Generators (SQGs) produce 100–1,000 kg/month and face intermediate regulatory requirements between VSQGs and LQGs.
DOT hazard class 3 is assigned to which category of dangerous goods?
Answer: Flammable liquids
DOT Class 3 is specifically designated for flammable and combustible liquids such as gasoline and acetone.
The Lower Explosive Limit (LEL) is defined as the minimum concentration of flammable vapor in air at which:
Answer: Ignition from an external source can cause an explosion
Below the LEL the mixture is too lean to ignite; at the LEL and above, an ignition source can cause a fire or explosion.
Which section of a GHS-compliant SDS is dedicated to first-aid measures?
Answer: Section 4
SDS Section 4 is standardized under GHS to contain first-aid measures, including routes of exposure and symptoms.
The primary purpose of secondary containment in chemical storage areas is to:
Answer: Contain spills and prevent environmental contamination
Secondary containment acts as a backup barrier to capture spills or leaks from primary containers before they spread and contaminate the environment.
