The federal Occupational Safety and Health Administration (OSHA) Hazard Communication Standard requires manufacturers or distributors of hazardous materials to assess the physical and health hazards of the chemical or product. This information must be included in the Material Safety Data Sheet (MSDS), which must be provided to the purchaser of the product with at least the initial shipment of the chemical. Per the Hazard Communication Standard, MSDSs must be obtained and maintained for every chemical used in the workplace. The Laboratory Standard requires laboratories to keep Material Safety Data Sheets (MSDSs) that are received from the manufacturer. The MSDSs must be accessible to all personnel during their work hours.
