What The !@#$%^&* Is A MSDS?

How to Read and Interpret a Material Safety Data Sheet!

•Objective

  to concisely inform you about the hazards of materials you work with so that you can protect yourself and respond to an emergency acts as a “crystal ball” - if you study it, you will see the future

•Purpose

 the material’s physical properties or fast acting health effects that make it dangerous to handle   the level of protective gear you need the first aid treatment to be provided when you are exposed to a hazard  the preplanning needed for safely handling spills, fires, and day-to-day operations  how to respond to accidents

•A Material is Considered Hazardous If--

 specifically listed in the law, 29CFR Part 1910, Subpart Z, Toxic and Hazardous Substances (the Z list)  assigned a Threshold Limit Value (TLV) by the American Conference of Governmental Industrial Hygienists, Inc (ACGIH)

 determined to be cancer causing, corrosive, toxic, an irritant, a sensitizer, or has damaging effects on specific body organs

•The MSDS Format

   must be in English have a heading cover 16 different informational categories

•Heading

 name and address of the manufacturer  telephone numbers   transportation emergency number nontransportation information and emergency numbers
