OSHA stands for the Occupational Safety and Health Administration, an agency of the U.S. Department of Labor. It sets and enforces workplace safety and health standards and provides training, outreach, education and assistance. It is not the same body as EU-OSHA, the European Agency for Safety and Health at Work.
In cable and electronics work, handling and storing some materials counts as a hazardous process. NASA-STD-8739.6B points to 29 CFR Part 1910, Subpart I (Personal Protective Equipment) and Subpart Z (Toxic and Hazardous Substances) for controls such as exhaust ventilation, fume extraction and employer-provided eye protection, gloves and respirators. State and local rules may also apply, and outside the U.S. OSHA usually reaches a supplier only through a contract flow-down.
