The PICO-GUARD is labeled “Class 1 / Division 1”. What does that mean?
The primary style of describing explosive environments in the U.S. is based on Class/Division/Groups, as described in Articles 500 and 505 of the National Electrical Code (NEC). Class refers to the types of fuels that may be present in an environment. The PICO-GUARD may be used in the presence of Class 1 types of fuels which include gases or vapors. Division refers to the possibility of ignitable concentrations of fuel being present in an environment. Division 1 means that the PICO-GUARD can be in an environment where ignitable concentrations of fuel may be present or likely to be present during normal operation, maintenance, or under fault conditions.
