Read the first 7 Asbestos Regulations & Prevention flashcards as text

  1. Which historical Navy regulation first established permissible exposure limits for asbestos aboard vessels?

    Answer: OPNAVINST 5100.23 (1987)

    OPNAVINST 5100.23, the Navy's occupational safety program instruction, established comprehensive asbestos controls and exposure limits for Navy personnel.

  2. What personal protective measure was required for Navy workers performing 'Class I' asbestos work — the removal of thermal system insulation?

    Answer: Full protective suit, gloves, and supplied-air respirator

    Class I asbestos work is the highest-risk category and demands full body protection including a supplied-air respirator and disposable coveralls.

  3. What is the primary purpose of a 'negative-pressure enclosure' during asbestos abatement aboard a Navy vessel?

    Answer: To contain asbestos fibers and prevent contamination of surrounding spaces

    Negative-pressure enclosures use exhaust fans with HEPA filtration to keep airborne fibers inside the work zone and prevent spread to adjacent areas.

  4. Under OSHA 29 CFR 1915 (Shipyard Employment), what is the 'excursion limit' for asbestos exposure over a 30-minute period?

    Answer: 1.0 f/cc

    OSHA's shipyard asbestos standard sets a short-term excursion limit of 1.0 fiber per cubic centimeter over any 30-minute sampling period.

  5. Which wetting method is required under OSHA and Navy standards to minimize airborne asbestos fibers during removal?

    Answer: Amended water (water with a surfactant) applied to keep material wet

    Amended water (water mixed with a wetting agent/surfactant) is required to keep asbestos material wet during removal, reducing fiber release.

  6. What is required before a Navy contractor can begin Class II asbestos work — disturbance of asbestos-containing floor or ceiling tiles?

    Answer: Competent person oversight and appropriate respiratory protection

    Class II work requires a competent person to oversee operations and workers must use appropriate respiratory protection based on exposure assessment.

  7. Which disposal method is mandated for asbestos waste removed from Navy ships under EPA regulations?

    Answer: Disposal at an EPA-approved asbestos waste disposal site in leak-tight containers

    EPA regulations require asbestos waste to be placed in leak-tight, labeled containers and disposed of only at approved waste sites that accept asbestos.
