What is the difference between Haz-Com and Chemical Hygiene?

Lab Safety Advisor, September 19, 2005

The Hazard Communication Standard was published in 1987 and applies to all industries.  It requires that all employees have a right to know what hazards they are working with and how to protect themselves from those hazards.  OSHA realized that laboratories had lots of hazardous chemicals but in small quantities and that the Haz-Com standard was overkill.  Therefore a special standard, Chemical Hygiene, took effect January of 1991.   The main differences include only listing chemicals with more than 1% of a hazard substance in them.  Also, chemicals that come in a "kit" do not have to be included in the chemical inventory.
