Learn about CID1 and CID2 intrinsic safety certification and how Getac ANSI/UL certified tablets and laptops can help you work in hazardous environments.
“Class 1 Division 2” is a classification for dangerous environments where fire hazards such as flammable gases, vapors, or liquids exist. CID2 classifications were established by the National Fire Protection Association’s Publication 70 and clarify the different classes and divisions of hazardous sites. In CID2 conditions, devices and equipment that meet CID2 standards minimize the risk for spark, ignition, or explosion. These standards and ATEX certifications verify similar degrees of protection, with CID2 used most commonly in North America and ATEX used in Europe.
CID2 is not the only explosive atmosphere classification. The governing classification system includes three classes and two divisions differentiating the level of explosive or otherwise dangerous gases, vapors, and mists present.
A explosive environment’s class is determined by the type of hazardous material present in the air.
Class 1: Gases, Vapors, and Mists
Class 2: Combustible Dust
Class 3: Easily ignitable fibers, or flyings.
Division is decided by the consistency of hazards present in the environment.
Division 1: Hazards are present in the air during normal operating conditions.
Division 2: Hazards are present in the air for limited amounts of time during system failures or faults.
With this system, the difference between a CID1 and CID2 environment is whether explosive materials are present consistently (CID1) or if they are usually contained in closed canisters or systems, and only exposed during a system failure (CID2).

Flammable particulates can be found in many industries. Any industry that deals with chemicals or combustible materials should use CID2-certified devices to protect workers and business assets. Industries that require CID2 certification include chemical makers, oil and gas companies, mining operations, and industrial and automotive manufacturers.
CID2 certification can be done with the help of UL (Underwriters Laboratories), a safety science leader and non-profit testing organization that evaluates, tests, and certifies devices built for hazardous locations. Their testing standards ensure that any certified device follows the standards of UL, American National Standards Institute (ANSI), and CSA standards provide enhanced safety in certain workplaces.
If certified for use in a hazardous area, devices will be marked with a UL label. These labels include further subdivisions that certify the types of hazardous materials that devices are protected against, and their temperature classes.
