Read the first 7 Safety & Infection Control flashcards as text

  1. Which organization establishes the Permissible Exposure Limits (PELs) for hazardous chemicals in the workplace?

    Answer: OSHA

    OSHA (Occupational Safety and Health Administration) sets and enforces Permissible Exposure Limits for chemical hazards in the workplace.

  2. A specimen container arrives in the laboratory leaking. What is the correct action?

    Answer: Open in a biological safety cabinet and transfer to a new container

    Leaking specimens should be handled in a biosafety cabinet; the contents transferred to a new container, and the area decontaminated to prevent exposure.

  3. Which personal protective equipment is specifically required when working with volatile chemicals that produce toxic vapors?

    Answer: Chemical fume hood with appropriate respirator

    Volatile toxic chemicals must be handled inside a chemical fume hood, and an appropriate respirator should be used when working with them outside the hood.

  4. What is the purpose of the eyewash station in a clinical laboratory?

    Answer: To flush eyes for 15 minutes after a chemical or biohazardous splash

    Eyewash stations are designed to deliver a continuous flow of water for at least 15 minutes to flush chemical or biohazardous splashes from the eyes.

  5. Which of the following organisms is classified as a BSL-3 pathogen requiring enhanced respiratory precautions?

    Answer: Mycobacterium tuberculosis

    Mycobacterium tuberculosis is a BSL-3 pathogen because it is transmissible by aerosol and can cause potentially lethal pulmonary disease.

  6. In the laboratory, what does 'engineering control' refer to in the hierarchy of hazard controls?

    Answer: Modifying the work environment to reduce exposure, such as using a biosafety cabinet

    Engineering controls are physical changes to the workplace or equipment—like biosafety cabinets or fume hoods—that reduce or eliminate worker exposure to hazards.

  7. When autoclaving biohazardous waste, what minimum temperature and time are typically required to ensure sterilization?

    Answer: 121°C for 15 minutes

    Standard autoclave sterilization requires 121°C (250°F) at 15 psi steam pressure for a minimum of 15 minutes to achieve sterilization.
