Read the first 7 Emergency Procedures and Spill Response flashcards as text

  1. When a flammable liquid spill occurs, which action must be taken immediately to prevent fire or explosion?

    Answer: Eliminate all ignition sources in the area

    Flammable liquid vapors can ignite from any spark or open flame; eliminating ignition sources is the critical first step to prevent fire or explosion.

  2. In a chemical emergency involving an inhalation hazard, what is the correct first aid priority?

    Answer: Move affected persons to fresh air

    Removing the affected person from continued exposure by moving them to fresh air is the primary first aid step for inhalation injuries.

  3. What is the primary purpose of a spill kit in a WHMIS-compliant workplace?

    Answer: To provide materials needed to contain and clean up hazardous spills

    Spill kits contain absorbents, neutralizers, PPE, and disposal bags that allow workers to safely contain and clean up hazardous chemical spills.

  4. Under WHMIS, who bears primary responsibility for ensuring workers are trained in emergency response procedures for hazardous products?

    Answer: The employer

    WHMIS places the responsibility on employers to provide workers with training that includes emergency procedures for all hazardous products used in the workplace.

  5. When skin contact with a corrosive chemical occurs, what is the recommended first aid action?

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

    Flushing with water for at least 15 minutes dilutes and physically removes corrosive chemicals from skin, reducing the depth and severity of chemical burns.

  6. What information in the SDS helps workers determine whether a chemical spill requires calling emergency services?

    Answer: Section 2 – Hazard Identification and Section 6 – Accidental Release Measures

    Section 2 identifies the severity of hazards and Section 6 specifies emergency notification requirements, together determining whether external emergency services are needed.

  7. Which type of fire extinguisher should NOT be used on a flammable liquid (Class B) fire?

    Answer: Water extinguisher

    Water can spread burning flammable liquids, enlarging the fire; CO2, dry chemical, or foam extinguishers are appropriate for Class B fires.
