Fundamentals of Class I, Division 1 - Hazardous Areas! 

Some locations are deemed “hazardous” due to the presence of explosive atmospheres. In order to ensure the safe installation of electrical products in these environments, they must comply with Standards that address their safety, and they must be certified as being in compliance.
The Class-division system is used in North America to distinguish hazardous areas and the degree of hazard present. Electrical devices must still be installed and used within these environments! They must be protected against becoming a source of ignition!
