By law, who is responsible for providing safety data sheets (SDSs)?

The responsibility for providing Safety Data Sheets (SDSs) primarily lies with manufacturers and importers of hazardous chemicals. According to regulatory standards such as the Occupational Safety and Health Administration (OSHA) Hazard Communication Standard (HCS) in the United States, these entities must ensure that:

1. SDSs are Prepared: Manufacturers and importers are required to develop and maintain SDSs for each hazardous chemical they produce or import.

2. Distribution Requirement: They must provide the SDSs to downstream users, such as employers, so that they can understand the hazards associated with the chemicals and how to handle them safely.

3. Updates: If there are any significant new information regarding hazards or handling procedures, manufacturers and importers must update the SDS to reflect these changes.

4. Accessibility: Employers are then responsible for maintaining copies of the SDSs and ensuring they are readily accessible to employees and anyone who may come into contact with hazardous materials in the workplace.

In summary, while the onus is on manufacturers and importers to create and distribute SDSs, employers also have a duty to ensure that these sheets are available and that their employees are informed about the chemicals they work with.
