Read the first 7 Safety Data Sheets (SDS) flashcards as text

  1. Which SDS section contains physical and chemical properties such as appearance, odor, pH, and boiling point?

    Answer: Section 9

    Section 9 (Physical and Chemical Properties) lists measurable characteristics including color, odor, pH, melting/boiling points, and flash point.

  2. Flash point, as listed in SDS Section 9, is defined as:

    Answer: The lowest temperature at which a liquid produces enough vapor to ignite momentarily near an ignition source

    Flash point is the minimum temperature at which a liquid releases enough vapor to briefly ignite when an ignition source is present.

  3. Section 10 of an SDS addresses:

    Answer: Stability and reactivity, including conditions to avoid

    Section 10 (Stability and Reactivity) describes chemical stability, hazardous decomposition products, and conditions or materials that may cause dangerous reactions.

  4. Acute and chronic health effects from chemical exposure are documented in which SDS section?

    Answer: Section 11 – Toxicological Information

    Section 11 (Toxicological Information) details routes of exposure, symptoms, acute vs. chronic health effects, and carcinogenicity data.

  5. An LC50 value listed in Section 11 of an SDS refers to:

    Answer: The lethal concentration that kills 50% of a test population via inhalation

    LC50 (Lethal Concentration 50) is the airborne concentration of a substance that kills 50% of exposed test animals, used to measure inhalation toxicity.

  6. Section 12 of an SDS (Ecological Information) is important because it:

    Answer: Describes impacts on the environment such as aquatic toxicity and persistence

    Section 12 covers environmental fate and effects, including aquatic toxicity, bioaccumulation potential, and persistence/degradability.

  7. Autoignition temperature, listed in SDS Section 9, is the temperature at which a substance:

    Answer: Ignites spontaneously without an external ignition source

    Autoignition temperature is the minimum temperature at which a substance will spontaneously ignite in air without any spark or flame present.
