The Occupational Safety and Health Administration (OSHA) mandates that each product used in a printing operation containing a hazardous ingredient must be accompanied by a Material Safety Data Sheet (MSDS). The MSDS was initially designed to convey important safety hazard information and measures to protect persons who may come in contact with a product, including employees, fire fighters, etc. Current and revised MSDSs must be kept on file for all products and are to be accessible to employees. Obsolete MSDS must be kept on file at a facility for 30 years.
The MSDS can also serve to provide important environmental compliance information, such volatile organic compound (VOC) content, Hazardous Air Pollutant (HAP) content, hazardous chemical ingredients and their CAS numbers for Section 313 Toxic Release Inventory reporting, flash point, product density, and vapor pressure. This information is required for hazardous air pollutant (HAPs) and VOC emission calculations, as well as other annual record keeping and reporting requirements, such as Superfund Amendments and Reauthorization Act (SARA) 311 and 312 reporting.
There is currently no required format for a MSDS, but the most common is the OSHA Form 174 that contains 9 different sections. Other formats may illustrate the same required information, but in an alternative location on the sheet. Each section of OSHA Form 174 is listed below and environmental information or description is provided where applicable.
