  1. A worker is exposed to a chemical mixture containing two substances with additive effects. The combined exposure index (CEI) is calculated as:

    Answer: C1/TLV1 + C2/TLV2

    For additively acting chemicals, the combined exposure index is the sum of each component's concentration divided by its TLV; a sum >1 indicates overexposure.

  2. Which GHS pictogram indicates an acute toxicity hazard (oral, dermal, or inhalation)?

    Answer: Skull and crossbones

    The skull and crossbones pictogram is used for substances with severe acute toxicity (categories 1–3).

  3. Under RCRA, which characteristic makes a solid waste hazardous due to its potential to cause explosions or fire?

    Answer: Ignitability

    Ignitability is the RCRA characteristic applied to wastes that can readily catch fire, including flammable liquids with flash point <60°C.

  4. What does the term 'threshold limit value – short-term exposure limit' (TLV-STEL) represent?

    Answer: 15-minute concentration that should not be exceeded

    The TLV-STEL is the concentration to which workers can be exposed for up to 15 minutes without suffering irritation, chronic tissue damage, or narcosis.

  5. Which agency publishes the Emergency Response Guidebook (ERG) used by first responders at hazmat incidents?

    Answer: DOT/PHMSA

    The ERG is published by the US DOT's Pipeline and Hazardous Materials Safety Administration (PHMSA) in cooperation with Transport Canada and Mexico's SCT.

  6. A chemical's boiling point is 35°C (95°F). What is the primary hazard concern at room temperature (25°C)?

    Answer: High volatility producing significant vapor concentrations

    A boiling point near or below ambient temperature means the liquid will rapidly volatilize, generating high vapor concentrations that pose inhalation and flammability risks.

  7. Which containment method is most appropriate as the FIRST action when a small quantity of a corrosive liquid spills on a laboratory floor?

    Answer: Absorb with an appropriate inert material and contain the spill

    Containing and absorbing the spill with inert absorbent material (e.g., vermiculite, dry sand) prevents spreading before neutralization or disposal.
