Material Safety Data Sheets (MSDS)

must have the following information on them:

 

Product Identification

 

  Hazardous Ingredients

  Physical Data (m.p., b.p., color, odor, etc.)

  Fire and Explosion Data (flash pt., autoignition temp, etc.)

  Reactivity Data (including incompatibilities)

  Toxicological Properties (including toxic doses, exposure limits)

  Preventative Measures

  First Aid Measures

  Preparation Information: who is responsible for the MSDS

 

Other Requirements for an MSDS:

 

  No blanks - mark with N/A if information not available

  Required data in each category. (Provided by supplier)

  Other information of awareness - Update info when available

  Consistency - label and MSDS should say the same thing

 

If suppliers MSDS are not readily available, then employers may generate their own MSDS for

the substance. However, to keep everyone honest, the original supplier MSDS must be made

available for comparison.

 

The operative phrase for MSDS is that they must be READILY AVAILABLE to the employee for

consultation BEFORE using the controlled product. It does no good to have the MSDS locked in

a filing cabinet in the supervisor's office when some grad student wants to work at 2:00 a.m.

some Sunday morning.

 

  MSDS library kept in some central location - accessible

 

Note that MSDS must be updated at least every three years. Watch out for supplier MSDS

That are already outdated!

 

*You can also obtain the MSDS from different suppliers homepages as in the highlighted links

on the WHMIS training main menu.
