Who is responsible for obtaining and maintaining the Safety Data Sheets (SDS) for hazardous chemicals used at a job site?

Explanation

Section 5194(g) puts it on the employer: maintain a safety data sheet in the workplace for each hazardous chemical in use, and ensure that it is readily accessible during each work shift to employees when they are in their work area. The manufacturer does have a duty of its own - to develop the sheet and provide it with the first shipment and again after a significant revision - but it runs to the purchaser, not to the worker on the scaffold. A general contractor coordinating a multi-employer site must make its own sheets available to the other employers and tell them where they are kept, under (e)(2), and that does not absorb each subcontractor's duty for its own chemicals. And a sheet sitting in a supplier's warehouse is not accessible in the work area.
