Read the first 6 Custodial and Maintenance Operations flashcards as text

  1. According to standard chemical safety practice, what should a custodian do before using an unfamiliar cleaning product?

    Answer: Read the product label and its Safety Data Sheet (SDS)

    OSHA hazard communication standards require that workers consult the label and Safety Data Sheet, which list proper use, dilution, personal protective equipment, and first-aid measures before handling any chemical.

  2. Why should ammonia-based cleaners never be mixed with chlorine bleach?

    Answer: The mixture releases toxic chloramine gas

    Combining ammonia and bleach produces chloramine vapors, which can cause serious respiratory harm or death in enclosed spaces, making this one of the most important chemical-safety rules in custodial work.

  3. What is the correct way to lift a heavy box of supplies from the floor?

    Answer: Bend at the knees, keep the back straight, and hold the load close to the body

    Safe lifting technique uses the leg muscles by bending at the knees, keeping the back straight, and holding the load close to the body's center of gravity, which minimizes back injury risk.

  4. A custodian must mop a hallway while students are still passing through the building. What is the most important first step?

    Answer: Place visible wet-floor warning signs around the work area

    Posting wet-floor signage before mopping warns pedestrians of the slip hazard and is the standard required safety practice for wet work in occupied buildings.

  5. A cleaning concentrate calls for a 1:64 dilution. How much concentrate is needed to make 2 gallons (256 ounces) of solution?

    Answer: 4 ounces

    A 1:64 ratio means 1 part concentrate per 64 parts total solution, so 256 ounces ÷ 64 = 4 ounces of concentrate.

  6. Which practice best prevents the spread of germs when cleaning classroom desks and door handles?

    Answer: Cleaning surfaces first, then applying disinfectant and letting it remain wet for the labeled dwell time

    Disinfectants only work when applied to a pre-cleaned surface and left wet for the contact (dwell) time stated on the label; wiping immediately or skipping cleaning leaves pathogens behind.
