Read the first 7 Labels and Safety Data Sheets flashcards as text

  1. SDS Section 11 addresses toxicological information. Which route of exposure is described when a chemical causes harm after being breathed in?

    Answer: Inhalation

    Inhalation refers to exposure through breathing in vapors, dusts, mists, or gases, which then enter the body via the respiratory system.

  2. A worker notices that the label on a container has been partially torn off and key information is missing. What should the worker do?

    Answer: Re-label the container immediately with required information before using it

    WHMIS regulations require containers to have legible, complete labels at all times; a damaged label must be replaced before the product is used.

  3. Which SDS section contains information about the environmental fate of a chemical, such as whether it bioaccumulates in organisms?

    Answer: Section 12

    Section 12 (Ecological Information) covers environmental impact data including ecotoxicity, persistence, degradability, and bioaccumulation potential.

  4. In WHMIS 2015, what does the health hazard pictogram (a person silhouette with a starburst on the chest) indicate?

    Answer: Serious long-term health effects such as carcinogenicity or reproductive toxicity

    The health hazard pictogram (exclamation-burst figure) signals serious long-term or severe health effects including carcinogenicity, reproductive toxicity, and organ damage.

  5. An SDS lists the TWA (time-weighted average) for a solvent as 50 ppm. What does this value represent?

    Answer: The average airborne concentration a worker can be exposed to over an 8-hour workday without harmful effects

    The TWA is the average exposure level over an 8-hour workday that is considered safe for repeated daily exposure without adverse health effects.

  6. Which of the following scenarios requires an employer to provide a workplace label?

    Answer: A hazardous product decanted into an unlabeled portable container for a worker to use

    Any time a hazardous product is transferred into a different container, the new container must have a workplace label with the product name, hazard information, and safe handling instructions.

  7. SDS Section 16 (Other Information) typically includes which type of information?

    Answer: The date the SDS was prepared or last revised

    Section 16 commonly contains the date of preparation or last revision, a list of abbreviations used, and any other information the supplier considers relevant but that doesn't fit in other sections.
