Hazard Zone / Class FAQ
Q: Can I use a piece of equipment approved for use in a Division 1 hazardous location in a Division 2 hazardous location?
A: Yes. If equipment has been approved for use in a Division 1 hazardous location, it can be used in a Division 2 hazardous location, providing it is in the same class and group.
Q: Can equipment approved for a Class I hazardous location be used in a Class II hazardous location?
A: No. Equipment approved for use in Class I hazardous locations cannot be used in Class II hazardous locations.
Q: Are Divisions and Zones equivalent to one another?
