Read the first 7 Laser Safety & Protocols flashcards as text

  1. Which ANSI standard governs laser safety in the United States for medical and cosmetic laser use?

    Answer: ANSI Z136.3

    ANSI Z136.3 specifically covers the safe use of lasers in health care facilities, including medical and cosmetic applications.

  2. What does the term 'Nominal Hazard Zone' (NHZ) define in laser safety?

    Answer: The area within which the beam irradiance exceeds the Maximum Permissible Exposure

    The NHZ is the space within which the level of direct, reflected, or scattered laser radiation exceeds the applicable MPE, requiring protective measures.

  3. A client reports increased photosensitivity due to a medication. What is the most appropriate course of action before proceeding with laser hair removal?

    Answer: Consult with the prescribing physician and reschedule if needed

    Photosensitizing medications can increase the risk of burns and adverse reactions, so physician clearance should be obtained before treatment.

  4. Which type of fire extinguisher is recommended for use in a laser treatment room?

    Answer: CO2 or dry chemical extinguisher

    CO2 or dry chemical extinguishers are appropriate for electrical and laser-related fires and do not damage equipment with water.

  5. What is the primary purpose of the Laser Safety Officer (LSO) in a clinical setting?

    Answer: To establish, implement, and enforce laser safety protocols

    The LSO is responsible for establishing and enforcing laser safety programs, including training, hazard evaluations, and protocol compliance.

  6. At what Fitzpatrick skin type does the risk of post-inflammatory hyperpigmentation (PIH) from laser treatment significantly increase?

    Answer: Fitzpatrick Type V-VI

    Darker skin types (V and VI) have more melanin, making them more susceptible to PIH and burns from laser treatments.

  7. What does 'duty cycle' refer to in the context of pulsed laser systems?

    Answer: The ratio of pulse-on time to the total period of the pulse cycle

    Duty cycle is the fraction of time a pulsed laser is 'on' during one complete pulse cycle, expressed as a percentage.
