Material Safety Data Sheet (MSDS)

Document that informs industrial purchasers and users of hazardous chemicals of the reasonably foreseeable physical and chemical hazards that may arise from the use of those chemicals. Most materials packaged for consumer use are exempt from the requirements of the Hazard Communication Standard (HCS). The MSDS should include precautions for normal use, handling, storage, disposal, and spill cleanup. The HCS requires that accurate information be provided on the MSDSs. This applies as much to “overwarning” on the MSDS and label, as well as the absence of information (“underwarning”).

Materiality

A fact, or statement, is material to a contract of insurance if knowledge of that fact would affect the decision of the underwriter to enter into the contract. If the fact would cause a change of any kind in the premium, the conditions of the policy, the perils insured, the persons insured, or in any other way, the policy is subject to being declared void.
