  1. Under OSHA's Hazard Communication Standard (HazCom 2012), how many sections are required on a Safety Data Sheet (SDS)?

    Answer: 16

    GHS-aligned SDSs must contain exactly 16 sections as specified by OSHA's HazCom 2012 standard.

  2. A chemist discovers that a stored chemical has exceeded its peroxide formation threshold. What is the FIRST action to take?

    Answer: Isolate the container and contact EHS before moving it

    Peroxide-forming chemicals that exceed safe thresholds are shock-sensitive and must be isolated in place while EHS is notified before any attempt to move them.

  3. Which engineering control is considered the most effective in the hierarchy of controls for chemical exposure?

    Answer: Elimination or substitution

    Elimination or substitution sits at the top of the hierarchy of controls because it removes the hazard entirely rather than managing exposure to it.

  4. When disposing of a mixture containing both a listed hazardous waste and a non-hazardous solvent, how is the entire mixture classified under RCRA?

    Answer: Hazardous, due to the mixture rule

    Under RCRA's mixture rule, any mixture containing a listed hazardous waste is itself classified as hazardous waste regardless of the proportions.

  5. What does the NFPA 704 blue quadrant on a chemical placard indicate?

    Answer: Health hazard

    The blue (left) quadrant of the NFPA 704 diamond represents health hazard, rated from 0 (minimal) to 4 (deadly).

  6. A chemical fume hood sash should be kept at or below the working height mark primarily to:

    Answer: Ensure adequate face velocity to protect the user

    Keeping the sash at or below the marked height maintains the minimum face velocity (typically 80–100 fpm) required to protect the user from vapor inhalation.

  7. Which document formally authorizes a laboratory to handle select agents and toxins regulated by the CDC/USDA?

    Answer: Select Agent Registration Certificate

    The CDC/USDA Select Agent Program requires facilities to obtain a Select Agent Registration Certificate before possessing, using, or transferring regulated select agents.
