OAR 437-004-9710
Acrylonitrile

Definitions: Acrylonitrile or “AN” (Chemical formula CH2=CHCN, CAS 107-13-1) means acrylonitrile monomer and includes Liquid AN. Liquid AN means acrylonitrile monomer in liquid form, and liquid or semi-liquid polymer intermediates, including slurries, suspensions, emulsions, and solutions, made during the polymerization of AN.

(1)

The employer is responsible to determine, before work begins, if any task or activity assigned to workers will result in a potential exposure to acrylonitrile.

(2)

Work that exposes employees to acrylonitrile must comply with Division 2/Z, 1910.1045, Acrylonitrile.
NOTE: The Division 2 Acrylonitrile rule does not apply to exposures which result solely from the processing, use, and handling of the following materials:
ABS resins, SAN resins, nitrile barrier resins, solid nitrile elastomers, and acrylic and modacrylic fibers, when these listed materials are in the form of finished polymers, and products fabricated from such finished polymers;
Materials made from and/or containing AN for which objective data is reasonably relied upon to demonstrate that the material is not capable – under the expected conditions of processing, use, and handling which will cause the greatest possible release – of releasing AN in airborne concentrations in excess of 1 ppm as an 8-hour time-weighted average, or
Solid materials made from and/or containing AN which will not be heated above 170 degrees F. during handling, use, or processing.
