  2. Flame spread - Wikipedia

    en.wikipedia.org/wiki/Flame_spread

    This test method measures flame growth on the underside of a horizontal test specimen, using the Steiner tunnel test. The result is derivation of a Flame Spread Index (FSI), [2] which is a non-dimensional number which is placed on a relative scale in which asbestos-cement board has a value of 0, and red oak wood has 100.

  3. Asbestos abatement - Wikipedia

    en.wikipedia.org/wiki/Asbestos_abatement

    In construction, asbestos abatement is a set of procedures designed to control the release of asbestos fibers from asbestos-containing materials. [1] Asbestos abatement is utilized during general construction in areas containing asbestos materials, particularly when those materials are being removed, encapsulated, or repaired.

  4. Asbestos - Wikipedia

    en.wikipedia.org/wiki/Asbestos

    Asbestos (/ æ s ˈ b ɛ s t ə s, æ z-,-t ɒ s / ass-BES-təs, az-, -⁠toss) [1] is a group of naturally occurring, toxic, carcinogenic and fibrous silicate minerals.There are six types, all of which are composed of long and thin fibrous crystals, each fibre (particulate with length substantially greater than width) [2] being composed of many microscopic "fibrils" that can be released into ...

  6. Occupational exposure banding - Wikipedia

    en.wikipedia.org/wiki/Occupational_exposure_banding

    The Hierarchy of Occupational Exposure Limits, of which occupational exposure banding is a member. Occupational exposure banding, also known as hazard banding, is a process intended to quickly and accurately assign chemicals into specific categories (bands), each corresponding to a range of exposure concentrations designed to protect worker health.

  7. Toxicity characteristic leaching procedure - Wikipedia

    en.wikipedia.org/wiki/Toxicity_characteristic...

    Toxicity characteristic leaching procedure (TCLP) is a soil sample extraction method for chemical analysis employed as an analytical method to simulate leaching through a landfill. The testing methodology is used to determine if a waste is characteristically hazardous, i.e., classified as one of the "D" listed wastes by the U.S. Environmental ...

  8. Smoke-developed index - Wikipedia

    en.wikipedia.org/wiki/Smoke-developed_index

    Like the Flame Spread Index, it is based on an arbitrary scale in which asbestos-cement board has a value of 0, and red oak wood has 100. The SDI is measured using a horizontal test specimen, according to the Steiner tunnel test protocol. The ASTM standard E84 defines a standard test method for surface flame spread and smoke density ...

  9. Occupational exposure limit - Wikipedia

    en.wikipedia.org/wiki/Occupational_exposure_limit

    An occupational exposure limit is an upper limit on the acceptable concentration of a hazardous substance in workplace air for a particular material or class of materials. It is typically set by competent national authorities and enforced by legislation to protect occupational safety and health.
