We recommend the ANSI standard for MSDSs. See http://www.schc.org/schcnewsite/pdf/revised_proposed_ANSI_400.1_std.pdf

I would recommend a written policy on the introduction of new chemicals into the workplace. The policy should address:

- Who is authorized to purchase chemicals, products, equipment that can introduce hazards to the workplace
- Who has authority to approve/disapprove new chemicals
- The criteria used to evaluate new chemicals, such as
hazards to health & environment
costs: PPE, engineering controls, waste disposal, storage, fire protection, etc.
regulatory requirements: OSHA, TSCA, CAA, CWA, RCRA, FIFRA, DOT, etc.
life cycle: potential for recycling, return to manufacturer, use and disposal by downstream users
- Amounts to be purchased
- How chemical compares to substitute chemicals (following above criteria)
- Pre-approval of chemicals used by contractors (consider not allowing any, unless purchased by your organization)
- What to do if chemicals are found or used on-site that did not go through this process
- Employee training on this procedure and chemical use, safety, disposal

Environmental Resource Center can develop a site-specific procedure for chemical procurement and management. Let me know if you'd like details on this service.
