Read the first 7 Safe Handling and Exposure flashcards as text

  1. A worker notices the WHMIS label on a drum is damaged and unreadable. What should the worker do?

    Answer: Stop using the product and report it to the supervisor for re-labeling

    Under WHMIS, products with damaged or missing labels must not be used until properly re-labeled based on the SDS.

  2. Section 8 of a WHMIS-compliant SDS covers exposure controls and personal protection. Which of the following would you expect to find there?

    Answer: Recommended glove material, respirator type, and occupational exposure limits

    SDS Section 8 specifies exposure controls (OELs) and recommended PPE such as gloves, eye protection, and respiratory equipment.

  3. During a chemical splash emergency, a WHMIS-trained worker should FIRST:

    Answer: Flush the affected area with large amounts of water for at least 15-20 minutes

    Immediate flushing with water for 15-20 minutes is the primary first aid response for chemical splashes to skin or eyes.

  4. A product's SDS indicates it has a Short-Term Exposure Limit (STEL) of 100 ppm. This means:

    Answer: Exposure at 100 ppm must not exceed 15 minutes, with limited occurrences per shift

    A STEL defines the maximum concentration allowed for short-duration exposures, typically no more than 15 minutes, with limited frequency.

  5. Which WHMIS hazard class specifically addresses materials that can cause cancer after repeated or prolonged exposure?

    Answer: Carcinogenicity (Health Hazard Class)

    Carcinogenicity is a WHMIS health hazard class for substances that can cause cancer following repeated or prolonged exposure.

  6. Proper storage of incompatible hazardous products under WHMIS requires:

    Answer: Segregating them so that accidental mixing cannot occur

    Incompatible chemicals must be stored separately to prevent dangerous reactions such as fire, explosion, or toxic gas generation.

  7. A worker spills a small amount of a toxic liquid on the floor. The SDS indicates it requires specific absorbent material. The worker should:

    Answer: Use the SDS-recommended absorbent material, contain the spill, and dispose of it per the SDS instructions

    SDS Section 6 specifies the correct spill cleanup materials and disposal method to prevent secondary exposure and environmental harm.
