Your workplace is required to have Material Safety Data Sheets available for every single hazardous chemical or substance you use or encounter as a part of your job. In other words, they cannot be locked in an office or filing cabinet to which you do not have access. If you request your own personal copy of a Material Safety Data Sheet, your employer has 15 working days to provide it. If you do not know where the MSDSs for your area are kept, find out . Employer Responsibilities Employers must ensure that each employee has a basic knowledge of how to find information on an MSDS and how to properly make use of that information.
Information is provided for each hazardous chemical.
A non-mandatory MSDS form that meets the Hazard Communication Standard requirements has been issued and can be used as is or expanded as needed. An identity on the MSDS must be cross-referenced to the identity found on the label. For a hazardous chemical mixture that has been tested as a whole to determine its hazards, the chemical and common names of the ingredients that are associated with the hazards, and the common name of the mixture must be listed. If the chemical is a mixture that has not been tested as a whole the chemical and common names of all ingredients determined to be health hazards and comprising 1 percent or greater of the composition must be listed. Chemical and common names of carcinogens must be listed if they are present in the mixture at levels of 0.1 percent or greater.
