What is the C1D2 Rating?

When selecting industrial computers for hazardous environments, safety and reliability are paramount. One important standard used to assess the safety of electronic equipment in these settings is the C1D2 rating, short for Class 1, Division 2. This rating helps define whether a device can be safely used in environments that may contain dangerous gases, vapors, or liquids that could cause explosions.

Understanding this rating and choosing the right equipment—like Tangent’s explosion-proof computers—can be crucial to ensuring operational safety.

The C1D2 rating comes from the National Electric Code (NEC) and is specifically used to classify hazardous locations. Let’s break down the components of this rating:

  • Class 1 (C1): This classification applies to environments where flammable gases, vapors, or liquids are present. It signifies that the area is at risk of explosion if these elements come into contact with electrical devices.
  • Division 2 (D2): Division 2 further refines the classification to areas where these hazardous substances are not normally present in ignitable concentrations under normal operating conditions, but might exist due to accidental leaks or system malfunctions.

In other words, C1D2-rated devices are designed to operate safely in areas where hazardous materials are present occasionally or during abnormal conditions. The equipment used must prevent ignition even if these volatile substances leak into the environment.

Industries dealing with flammable substances need equipment that can withstand exposure to potentially dangerous environments. Examples include:

Refineries, pipelines, and drilling operations often work with volatile chemicals and gases.

Manufacturing processes may involve flammable solvents or gases.

Chemical plants frequently handle combustible materials in their production lines.

Certain manufacturing steps may involve the use of combustible dust, vapors, or alcohol-based substances.

Choosing the right industrial computer is critical for safety and productivity in hazardous environments. Tangent’s explosion-proof computers stand out as an excellent selection for industries requiring C1D2-rated devices. Here’s why:

Tangent’s explosion-proof computers are specifically engineered for environments where ignitable gases or liquids could be present.
