Guidance on Training and Information: The HCS requires employers to inform employees about the requirements of the standard, operations where hazardous chemicals are present, location of the written HCS program, location of MSDSs, and the location of the hazardous chemical inventory (29 CFR 1910.1200(h)(2)). Employers are required to train employees in the methods used to detect the presence or release of a hazardous chemical, the physical and health hazards of the chemical, and control measures (including work practices, emergency procedures, and personal protective equipment) (29 CFR 1910.1200(h)(3)). Updated MSDSs and labels provide necessary baseline information for employee training regarding physical and health hazards, personal protective equipment, and emergency procedures. Chemical manufacturers, importers, and employers who use diacetyl or FFCD must evaluate those operations and tasks where these chemicals are present and provide the required information and training to employees. Employers should determine whether additional training is required. New hazard information discussed in this guidance, such as occurrences of fixed airways obstructive disease in employees exposed to diacetyl and FFCD, may warrant additional training.
