Material Safety Data Sheets (MSDS)
Information that can be found on MSDS
Material Safety Data Sheets (MSDSs) can be a valuable source of information on the hazardous properties of chemicals although some manufacturers product more useful MSDSs than others. The OSHA Hazard Communication Standard requires that manufacturers supply an MSDS with each chemical purchased. The standard also requires that MSDSs are maintained in the workplace for each hazardous chemical which they use.
MSDSs can be different from each other in format and somewhat in content, but they are required to contain at least the information listed below:
1. The name, address, and telephone number of the chemical manufacturer other responsible party who can provide additional information on the hazardous chemical and appropriate emergency procedures
2. The chemical and common name(s) of all ingredients which have been determined to be health hazards, and which comprise less than 1% (0.1% for carcinogens).
3. Physical and chemical characteristics of the hazardous chemical
4. The physical hazards of the chemical including the potential for fire, explosion, and reactivity
5. The health hazards of the chemical including signs and symptoms of exposure
6. The primary route(s) of entry
7. The OSHA permissible exposure limit (PEL), ACGIH threshold limit value (TLV), and any other exposure limit used or recommended
8. Whether the hazardous chemical is listed in the National Toxicology Program (NTP) Annual Report on Carcinogens or has been found to be a carcinogen in the International Agency for Research on Cancer (IARC) Monographs, or by OSHA.
9. Any generally applicable precautions for safe handling and use which are known to the chemical manufacturer.
10. Any generally applicable control measures
11. Emergency and first aid procedures
12. The date of preparation of the material safety data sheet
