What You Need to Know About Class 1 Division 2 (C1D2) for Hazardous Locations

When equipping hazardous work areas with rugged tablets, understanding the importance of Class 1 Division 2 (C1D2) certification is crucial. This certification ensures that electronic devices used near flammable hazards adhere to safety standards that prevent explosions and ensure worker safety. But what exactly is C1D2, and how do you determine if your operation requires C1D2-certified tablets?

Explaining C1D2 Certification

C1D2 is a safety standard that identifies which technologies are safe for use in hazardous environments. It guarantees that in the event of a worst-case scenario, a certified device will not ignite any hazardous substances nearby.

Classification System Breakdown

The North American classification system details potential hazards into classes, divisions, groups, and temperature codes:

• Classes: Specify the types of hazardous materials in the environment.
  • Class 1: Flammable gases or vapors.
  • Class 2: Combustible dust.
  • Class 3: Fibers and flyings.
• Divisions: Indicate how frequently hazardous conditions are present.
  • Division 1: Hazards are present during normal operations.
  • Division 2: Hazards are present under abnormal conditions only.
• Groups: These are categorized from A to G and detail specific types of gases, vapors, and dusts in the environment.
• Temperature Codes: Indicate the maximum surface temperature a device can reach without causing ignition.

Safety Ratings within C1D2

Devices are either rated as non-incendive or intrinsically safe:

• Non-incendive devices are designed to not produce enough energy (heat or spark) to ignite under normal conditions.
• Intrinsically safe devices are engineered to prevent ignition even in abnormal or faulty conditions.

C1D2 Certification Requirements

C1D2 certification is essential in locations where explosive gases, vapors, dust, or fibers might be present. Typical environments requiring this certification include chemical plants, oil refineries, paint shops, flour silos, and other similar hazardous areas.

Choosing the Right Equipment

Selecting C1D2-certified equipment is paramount for maintaining safety and compliance in hazardous settings. Such equipment is specifically designed to prevent accidental ignitions from electrical sparks or excessive heat, ensuring that operations in volatile environments are conducted safely.

Investing in the right C1D2 certified devices not only helps protect your employees but also safeguards your operations against potential risks and liabilities, maintaining compliance with safety regulations and standards. When choosing devices for hazardous areas, it’s critical to consider their certification, operational parameters, and safety features to ensure they meet the stringent requirements needed for these challenging environments.
