Protection Method Overview
Arm yourself with knowledge and get your products on the right path
It is essential to determine which protection method is right for your products. To choose your protection method, identify the intended and potential applications for your product. Understanding the area classification as well as divisions and zones will be key to helping identify the method of protection that is most suited to your needs. For additional technical information, download our Poster, Guide to Equipment Certification Requirements for Hazardous Locations.
The charts below provide an overview of all protection methods according to the Class of the environment as well as the region.
