Carole,
 
The purpose of an MSDS is that it be read and that the hazards and precautions be understood as correct.
 
THEREFORE, IF THE PRECAUTIONS INCLUDE A STATEMENT THAT "THE EQUIPMENT HAD [SIC] TO BE EXPLOSION PROOF" THEN MAKE SURE THAT IT IS EXPLOSION PROOF. 
 
If others reply to your inquiry indicating that they ignore such information in an MSDS, you can be CERTAIN that sooner or later they will not be able to answer any email inquiries until they re-build their facilities that were destroyed in an explosion.

Good day everyone,

One of our researcher suddenly wants to use sodium azide in a chemical reaction.  I=92m aware of the risks associated with that chemical, but never used it as a chemist.  If you have any =93Thing to do or not do=94 experience or knowledge to share with us, we are very interested in reading them.

I read in the MSDS that the evacuation equipment had to be explosion-proof.  I can understand why, but is it the case in your institutions?

Thanking you in advance for your responses!

Carole
