A Safety Data Sheet, formerly called Material Safety Data Sheet, is a detailed information document prepared by the manufacture or importer of a hazardous chemical. It describes the physical and chemical properties of the product. SDS’s contain useful information such as toxicity, flash point, procedures for spills and leaks, storage guidelines, and exposure control. The information contained in the SDS is largely the same as the MSDS, except now the SDSs are required to be presented in a consistent user‐friendly, 16 section format. In addition, OSHA requires that SDS preparers provide specific minimum information as detailed in Appendix D of 29 CFR 1910 1200. Below is breakdown of the information to be contained in each section of the SDS.

  • Section 1 – Identification identifies the chemical on the SDS as well as the recommended uses. It also provides the essential contact information of the supplier.
  • Section 2 – Hazard(s) identification includes the hazards of the chemical and the appropriate warning information associated with those hazards.
  • Section 3 – Composition/information of ingredients identifies the ingredients(s) contained in the product indicated on the SDS, including impurities and stabilizing additives. This section includes information on substances, mixtures, and all chemicals where a trade secret is claimed
  • Section 4 – First‐aid measures describes the initial care that should be given by untrained responders to an individual who has been exposed to the chemical.
  • Section 5 – Fire‐fighting measures lists recommendations for fighting a fire caused by the chemical, including suitable extinguishing techniques, equipment, and chemical hazards from fire.
  • Section 6 – Accidental release measures provides recommendations on the appropriate response to spills, leaks, or releases, including containment and cleanup practices to prevent or minimize exposure to people, properties or the environment. It may also include recommendations distinguished between responses for large and small spills where the spill volume has a significant impact on the hazard.
  • Section 7 – Handling and storage provides guidance on the safe handling practices and conditions for safe storage of chemicals, including incompatibilities.
  • Section 8 – Exposure controls/personal protection indicates the exposure limits, engineering controls, and personal protective equipment (PPE) measures that can be used to minimize worker exposure.
  • Section 9 – Physical and chemical properties identifies physical and chemical properties associated with the substance or mixture such as odor, appearance, relative density, etc..
  • Section 10 – Stability and reactivity describes the reactivity hazards of the chemical and the chemical stability information. This section is broken into 3 parts: reactivity, chemical stability, and other.
  • Section 11 – Toxicological information identifies toxicological and health effects information or indicates that such data are not available. This includes routes of exposure, related symptoms, acute and chronic effects, and numerical measures of toxicity.
  • Section 12 – Ecological information provides information to evaluate the environmental impact of the chemical(s) if it were released to the environment.
  • Section 13 – Disposal considerations provides guidance on proper disposal practices, recycling or reclamation of the chemical(s) or its container, and safe handling practices. To minimize expose, this section should also refer the reader to Section 8 (Exposure Controls/Personal Protection) of the SDS.
  • Section 14 – Transportation information includes guidance on classification information for shipping and transporting of hazardous chemical(s) by road, air, rail or sea.
  • Section 15 – Regulatory information identifies the safety, health, and environmental regulations specific for the product that is not indicated anywhere else on the SDS.
  • Section 16 – Other information indicates when the SDS was prepared or when the last known revision was made. The SDS may also state where the changes have been made to the previous version. You may wish to contact the supplier for an explanation of the changes. Other useful information also may be included here.

It is important to note that the SDS has to be available upon request and/or it has to be on‐site when chemicals are in use. If you would like additional information on Safety Data Sheets and the information contained in the document(s) please refer to Occupational Safety and Health Administration website Until next time my friends, be prepared and stay safe.
