Most OSHA PELs are 8-hour time-weighted averages (TWA), although there are also Ceiling and Peak limits, and many chemicals include a skin designation to warn against skin contact. (4) The chemical formula for hydrochloric acid is HCl, and its molecular weight is 36.47 g/mol. BEIs represent the levels of determinants that are most likely to be observed in specimens collected from healthy workers who have been exposed to chemicals in the same extent as workers with inhalation exposure at the TLV. OSHA's Hazard Communication Standard (HCS) is designed to ensure that information about chemical and toxic substance hazards in the workplace and associated protective measures is disseminated to workers. Provides references that aid in recognizing hazards associated with chemical hazards and toxic substances. What Is the Chemical Composition of Vinegar? Respiratory protection is required to be used if engineering or work practice controls are infeasible or while engineering controls are being implemented.
