Hazardous Locations

Today’s rugged devices are used in many different industries and workflows around the world, including hazardous locations laden with flammable gases and flammable vapors. Yet, even across the most industrial sectors, there are inherently different levels of risk involved with each worker’s use of tough mobile computers in explosive environments. Whether you're in mining, oil and gas, the military or even warehousing, you likely encounter dust, gas or high-heat elements that increase the risk of explosions when they make contact with electrical equipment. That means safety must be a priority when introducing any ruggedized computer, including rugged tablets, into hazardous locations – even when workers' safety training and skill are top-notch.

Class1/Div.2(C1/D2) or Class1/Zone2(C1Z2) and ATEX Compliant Tablets for Hazardous Locations (Hazloc)

Do you know if your rugged mobile PC is C1D2/C1Z2 or ATEX compliant for explosive environments?

When eliminating – not just minimizing – risk is non-negotiable in hazardous locations, it's critical that you invest in either a C1D2/C1Z2- or ATEX-compliant rugged tablet PC and a partner that can demonstrate the safety of its tough mobile computer technology. Zebra offers both.

We understand that the best way to safely harness the advantages of rugged mobile computers in Hazardous Locations (Hazloc) is to employ ruggedized tablets that are either C1D2/C1Z2-compliant or ATEX-compliant, depending on your regional operating standards. That's because C1D2/C1Z2- and ATEX-compliant tablets are engineered with "intrinsic safety" techniques applicable to both "live use" and rugged tablet failure situations in explosive locations.

Whether you want to:

  • Streamline Oil & Gas infrastructure inspections
  • Improve plant safety and integrity across petrochemical manufacturing
  • Automate asset management at mining sites

You will always want – and need – a tough mobile tablet that boasts the highest level of Hazloc safety. That means you'll always want and need a C1D2/C1Z2-compliant or ATEX-compliant tablet. Don't settle for less when mobile worker safety is mandatory in potentially explosive environments.

Understanding Hazardous Location (Hazloc) Testing for Rugged Computers

There are two widely accepted explosive atmosphere or hazardous location standards for rugged computers used in hazardous environments worldwide: C1D2 (and its newer C1Z2 counterpart) and ATEX.

CID2/C1Z2 is an ANSI/ISA North American certification for hazardous locations. This standard identifies three types of hazardous locations categorized by Class I (gases, vapors and liquids), Class II (dusts) and Class III (fibers and flyings). It also identifies two divisions that indicate the level of explosive elements anticipated in each work location: Division 1 (or Zone 1) means that an explosive environment may be present during normal operating conditions. Division 2 (or Zone 2) means that explosive environment may be present only during a fault condition and for a limited time.

The ATEX Certification is based on the requirements of two European directives – Directive 99/92/EC (also known as ATEX Workplace Directive) and Directive 94/9/EC (the ATEX Equipment Directive). Derived from the French title of the latter – Appareils destinés à être utilisés en ATmosphères EXplosives – ATEX directives describe what equipment and work environment is allowed in explosive environments.

Both C1D2 and ATEX standards are commonly recognized in most regions of the world and both offer comparable levels of rugged mobile work protection in hazardous locations.
