Goal: this task will increase the success of the goal to apply Cal/OSHA safety suggestions.
John Mitchell published this Cognitive Task at under Industry | Construction
Doers: 1 | Form: Cognitive Task | Phase: Engagement | Type: Pre-Event | Level: 1 | Code:
Start: Jan 25, 2020 | When: | Duration: 5 Minute(s)
  • The next Steps cover Cal/OSHA safety regulations for Explosion Hazards. Where appropriate, we have referenced the code from Title 8 of the California Code of Regulations.

    The topics we will cover in this isoBlog are:

    -Potential Hazards
    -Combustible Dust
    -Flammable Vapors

    After each of the next Steps, select the 'successful' response to indicate that you have read and understand the Step.

    Select 'successful' now and proceed.
  • Potential Hazards

    At times employees may be exposed to explosion hazards without their knowledge.

    In addition to substances (such as dynamite) that are designed specifically for the purpose of creating explosions, there are substances that will cause an explosion when present in certain concentrations and exposed to an ignition source.

    The Steps 3 through 4 will outline the Safety Orders (SOs) to control these hazards from occurring.
  • Combustible Dust

    -Combustible dust concentrations must be controlled at or below 25% of the Lower Explosive Limit (LEL) unless all ignition sources are eliminated or identified and specifically controlled

    -Accumulated and settled combustible dusts must be cleaned up to prevent a fire or explosion

    -Cleaning with compressed air and blowing combustible dust may be done only when other methods cannot be used, when possible sources of ignition have been eliminated, and when hoses and nozzles are grounded
  • Flammable Vapors:

    -Ventilation in enclosed places must be sufficient to prevent flammable vapor or gas concentrations from exceeding 25% of the Lower Explosive Limit (LEL)

    -No source of ignition is permitted indoors or outdoors where vapor or gas concentrations may reasonably be expected to exceed 25% of the LEL

    -Employers need to be aware that most flammable vapors are toxic even at a very low concentration and can cause adverse health effects. Employers must have control measures to keep employees safe

    Note: for more information, go to the 'unscheduled' tab above and schedule the isoBlog titled: 'Confined Spaces'.
  • How much did this isoBlog help you to understand the Cal/OSHA safety regulations for Explosion Hazards, including:
