  1. Which chemical storage practice is most critical to preventing dangerous reactions between stored substances?

    Answer: Segregation by chemical compatibility

    Segregating chemicals by compatibility prevents dangerous reactions such as fires, explosions, or toxic gas generation when incompatible substances accidentally contact each other.

  2. Oxidizers must be stored separately from which class of chemicals to prevent fires and explosions?

    Answer: Flammables and combustibles

    Oxidizers supply oxygen that accelerates combustion, making their separation from flammables and combustibles essential to preventing fires and explosions.

  3. According to OSHA 1910.106, flammable liquids storage cabinets must limit internal temperature to a maximum of what during a 10-minute fire test?

    Answer: 325°F

    OSHA 1910.106 requires flammable liquids storage cabinets to maintain an internal temperature no greater than 325°F during the standard 10-minute fire exposure test.

  4. What is the maximum capacity allowed for a safety can used to store flammable liquids?

    Answer: 5 gallons

    OSHA standards limit safety cans to a maximum capacity of 5 gallons; these cans are also required to have self-closing lids and flash arrestors.

  5. The NFPA 704 'diamond' rating system is primarily designed to inform:

    Answer: Emergency responders about health, flammability, instability, and special hazards

    The NFPA 704 diamond provides color-coded numerical ratings (0-4) for health, flammability, and instability hazards plus special hazard notation, specifically to guide emergency responders at incident scenes.

  6. Chemical fume hoods are classified as which type of hazard control?

    Answer: Engineering control

    Fume hoods provide local exhaust ventilation, removing hazardous vapors and fumes from the worker's breathing zone through a physical engineering solution.

  7. Per ANSI Z358.1, emergency eyewash stations must be located within what travel time from a corrosive chemical hazard?

    Answer: 10 seconds

    ANSI Z358.1 requires emergency eyewash stations to be reachable within 10 seconds of travel (approximately 55 feet) from corrosive chemical hazards to minimize eye damage.
