Class 1 Division 2, or C1D2, is one of the most important factors to consider when looking for rugged tablets to use in hazardous industries. Any electronics being used in a potentially dangerous environment or around flammable hazards must be C1D2 certified to prevent dangerous explosions and ensure worker safety. But what exactly does C1D2 mean and how do you know if your operation needs certified tablets?

What is C1D2?

Simply put, C1D2 is part of a classification system that dictates the level of dangerous or explosive vapors, gas, dust, or fibers and what kind of technology is permissible and safe to use when they are present.

This system is divided into three different classes and two different divisions, based upon what kind of hazards are present and how often.

Class 1 - Flammable vapors or gases are the present hazard

Class 2 - Combustible dust is present

Class 3 - Easily ignitable fibers or flyings in air

The divisions signify how often those hazards are present:

Division 1 – Hazard is present during normal operating conditions. This can be caused due to frequent maintenance or equipment failure.

Division 2 – Hazard is present, but in closed canisters or systems, and are only exposed through system failures or ruptures.

These classes and divisions are paired, depending on what the hazard is and how often it’s present. For example, C1D1 represents hazardous gas that’s present during normal working conditions, while C1D2 is hazardous gases that are present but remain in a container or system under normal circumstances.

Where is the C1D2 Certification Needed?

The short answer is anywhere that potentially explosive gasses, vapors, dust, or fibers are present or potentially present. That would include chemical plants, oil/gas refineries, paint shops, cleaning facilities, mills, flour silos, mining, and loading facilities for flammable gases, liquids, and solids. For C1D2 specifically, the certification covers usage in areas where combustible gases such as Acetylene, Hydrogen, Ethylene, and Propane (Groups A-D) are present abnormally. This means under a worse-case scenario, a malfunctioning tablet will not ignite the substance around it causing a fire, explosion or other catastrophe.
