Hazardous Environments:
Guidelines & Observations

EVT PRO Intrinsic Safe models have been designed 
and approved for either  CSA  or ATEX requirements

ALWAYS consult local agencies for approvals needed 
beyond what has been provided

ALWAYS consult plant personnel before testing to 
ensure compliance 

–

especially in areas where 

hazardous gases, liquids are in use.  

Secure all proper permits and approvals before 
testing;  obtain hot works permits 

Best engineering practices should be adhered to in 
hazardous environments such as the use of PPE, 
non-sparking tools, no flames, and other.  Consult 
local plant personnel.  

Seek out additional “specialized”  training when 

testing in hazardous environments 

This overview is not intended to serve as training 
on Hazardous environments rather to advise of its 
danger and the need for additional training, 
consulting and approvals.
