  2. Acrylonitrile - Wikipedia

    en.wikipedia.org/wiki/Acrylonitrile

    Routes of exposure include inhalation, oral, and to a certain extent dermal uptake (tested with volunteer humans and in rat studies). [25] Repeated exposure causes skin sensitization and may cause central nervous system and liver damage. [24] There are two main excretion processes of acrylonitrile.

  3. 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.

  4. 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 .

  5. Acrylonitrile butadiene styrene - Wikipedia

    en.wikipedia.org/wiki/Acrylonitrile_butadiene...

    Acrylonitrile butadiene styrene (ABS) (chemical formula (C 8 H 8) x · (C 4 H 6) y · (C 3 H 3 N) z) is a common thermoplastic polymer. Its glass transition temperature is approximately 105 °C (221 °F). [4] ABS is amorphous and therefore has no true melting point. ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the ...

  6. Recommended exposure limit - Wikipedia

    en.wikipedia.org/wiki/Recommended_exposure_limit

    National Institute for Occupational Safety and Health (NIOSH) RELs are designed to protect the health and well-being of workers by recommending safe exposure levels. To really use these guidelines well, safety professionals need to understand the recommended exposure levels, how to measure them, and ways to make sure workers aren't exposed to harmful stuff.

  7. Recycling codes - Wikipedia

    en.wikipedia.org/wiki/Recycling_codes

    Recycling codes on products. Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process.The presence on an item of a recycling code, a chasing arrows logo, or a resin code, is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of.

  8. Polyacrylonitrile - Wikipedia

    en.wikipedia.org/wiki/Polyacrylonitrile

    Acrylonitrile is commonly employed as a comonomer with styrene, e.g. acrylonitrile, styrene and acrylate plastics. Labelling of items of clothing with acrylic (see acrylic fiber) means the polymer consists of at least 85% acrylonitrile as the monomer. A typical comonomer is vinyl acetate, which can be solution-spun readily to obtain fibers that ...

  9. IARC group 3 - Wikipedia

    en.wikipedia.org/wiki/IARC_Group_3

    Agents, mixtures and exposure circumstances that do not fall into any other group are also placed in this category. The IARC Monographs on which this list is based assess the hazard linked to the agents, they do not assess the cancer risk of the agents. [1] The list is up-to-date as of January 2024. [2]
