• The Hazard Communication Standard (HAZCOM) also known as the “Right to Know” Act, stipulates that every employee in the workplace has a right to know what the properties and hazards are of any chemical that is used in their workplace.  The Standard also addresses chemical labeling and storage.  Another cornerstone of the Standard is that each chemical must have a uniform “Material Safety Data Sheet (MSDS)” that provides the characteristics of the chemical. 


    You can find an outline of the 16 different sections of the MSDS here (Chemical Labels-HMIS). Other information pertinent to chemical safety can be found in these handouts in English and Spanish (Chemical Labels-NFPA, Chemicals Spanish). The present labeling format for chemicals used is primarily the NFPA (National Fire Protection Association) (Chemical English) and HMIS (Hazard Management Identification System) (MSDS English) systems.

  • In March of 2012, the final rules were published to implement the Global Harmonization System (GHS) for classification and labeling of chemicals in the workplace.  Under the rule, all employees must be trained by December 1, 2013 on the components of GHS.  The final rule requires chemical product manufacturers to adopt the updated standard by June 1, 2015 and chemical product distributors by December 1, 2015.
