  1. What is the minimum air pressure relationship required in the decontamination area relative to adjacent clean areas?

    Answer: Negative pressure

    Decontamination areas must maintain negative air pressure so contaminated air flows inward and does not migrate to clean or sterile areas.

  2. Which type of glove provides the best cut resistance when processing sharps in the decontamination area?

    Answer: Puncture-resistant utility gloves

    Puncture-resistant utility gloves (such as stainless-steel mesh or heavy-duty nitrile) are required for handling sharps during decontamination to reduce cut injuries.

  3. According to ANSI/AAMI ST79, what is the recommended minimum number of air exchanges per hour in the decontamination area?

    Answer: 10 air changes per hour

    ANSI/AAMI ST79 recommends a minimum of 10 air changes per hour in the decontamination area to dilute airborne contaminants.

  4. A CS technician notices a chemical spill of a high-level disinfectant. What is the FIRST action to take?

    Answer: Alert coworkers and don appropriate PPE before approaching

    The first priority is personal safety — alert others and don appropriate PPE (gloves, eye protection, gown) before approaching any chemical spill.

  5. Which label system uses pictograms and a 1–4 hazard rating on a diamond-shaped label for chemical hazards?

    Answer: NFPA 704 diamond

    The NFPA 704 system uses a four-colored diamond with numerical ratings (0–4) for health, flammability, instability, and special hazards.

  6. Which practice helps prevent musculoskeletal injury when lifting heavy instrument trays?

    Answer: Using leg muscles and keeping the back straight

    Proper lifting technique requires bending the knees, using leg muscles, and keeping the spine in a neutral position to protect the back.

  7. What should a CS technician do with a cracked or damaged sterilization container before sterilization?

    Answer: Remove it from service and report it for repair or replacement

    Cracked or damaged rigid containers must be removed from service immediately because structural defects compromise sterility maintenance and can cause injury.
