View Rule

The existing OSHA regulations in Subpart Q (Welding, Cutting and Brazing) address both physical (safety) and chemical (health) hazards that are associated with welding. Examples of safety and health risks in such operations include exposure to welding fumes (chromium, cadmium, manganese), fire hazards, arc flash, eye injury, etc. OSHA is concerned that the current approach to chemical exposures, which relies upon several individual PELs, may be inadequate to address the true health risk associated with this complex chemical mixture. Additionally, the OSHA standards relies upon, and incorporates by reference, outdated ANSI standards issued in the 1960s, which are likely inadequate to address safety issues. This project is in accordance with Executive Order 13563, which is intended to facilitate the review of existing regulations that may be outmoded, ineffective, insufficient, or excessively burdensome, and to modify, streamline, expand, or repeal them.  OSHA is withdrawing this entry from the agenda at this time due to resource constraints and other priorities.
