Read the first 7 Hazard Recognition and Control flashcards as text

  1. During a workplace inspection, a safety specialist identifies a chemical stored without a label. Under HazCom 2012, what information is NOT required on a shipped container label?

    Answer: Manufacturer's SDS revision date

    GHS container labels require signal words, pictograms, hazard statements, precautionary statements, and supplier identity—not the SDS revision date.

  2. Which method is used to quantitatively rank hazards by multiplying the likelihood of occurrence by the severity of consequences?

    Answer: Risk matrix scoring

    A risk matrix multiplies likelihood by severity to produce a risk score that helps prioritize hazard controls.

  3. A construction site has an open excavation 6 feet deep. OSHA requires which control to protect workers from cave-in?

    Answer: Sloping, shoring, or trench box protection system

    OSHA 29 CFR 1926.652 requires a protective system (sloping, shoring, or trench boxes) for excavations 5 feet or deeper.

  4. What type of hazard is produced when welding galvanized steel without ventilation?

    Answer: Chemical hazard from metal fume

    Welding galvanized steel releases zinc oxide fumes that can cause metal fume fever, a chemical inhalation hazard.

  5. Which leading indicator is MOST useful for proactively identifying hazards before incidents occur?

    Answer: Near-miss reporting frequency

    Near-miss reporting is a leading indicator that reveals hazardous conditions before they result in actual injuries.

  6. A safety specialist finds that a chemical process operates near its lower explosive limit (LEL). What control would BEST address this flammable atmosphere hazard?

    Answer: Install continuous LEL monitoring with automatic ventilation

    Continuous LEL monitoring with automatic ventilation provides real-time control by diluting flammable vapors before they reach dangerous concentrations.

  7. Under OSHA's Process Safety Management (PSM) standard, which chemical triggers PSM requirements at or above its threshold quantity?

    Answer: Chlorine

    Chlorine is listed as a PSM-covered chemical with a threshold quantity of 1,500 pounds under 29 CFR 1910.119.
