C1D1, C1D2, and Surveillance: Everything Known About

When you work in an industry that constantly deals with fuel or hazardous materials, there is a strong likelihood that you’ve encountered terms like C1D1 and C1D2. For business owners and trained personnel in the United States, these terms are classifications of specific areas or environments set by the National Fire Association or NFPA. When either distinction is applied, the work environment must have special equipment to function normally, with examples including:

  • Appropriate safety equipment
  • Explosion-proof or protected cameras
  • Insulated and explosion-proof electronics
  • Specially designed outlets

By no means will the average electronic or security camera cut it in such an environment, and A1 Security Cameras provides only the best security cameras fit to work in C1D1 or C1D2 classified environments. We feature both explosion-proof and explosion-protected cameras that are sure to help add the best possible security to your business. Our experienced professionals are perfect for your security camera needs, whether it includes questions about products or system design help. Contact us today for more information!

What is C1D1?

In basic terms, C1D1 or class 1, division 1, is a classification that describes hazardous work environments where fire hazards exist and may or will lead to an explosion due to the regular presence of flammable materials like gases or vapors. Regular presence, in this case, includes environments where such hazardous materials are:

  • Regularly present
  • From malfunctioning or damaged equipment
  • Through the incorrect application of processes

As seen, C1D1 environments specifically include hazardous materials that can catch fire and lead to explosions on a regular basis. This means that all electrical equipment must be designed to prevent sparking or internally contain an adverse reaction if one were to occur.

What security cameras are used with C1D1?

Explosion-proof security cameras are used in locations that are classified as C1D1 hazardous areas. Similar to the surrounding electronics they would be installed with, such cameras are designed to explicitly not spark or ignite surrounding materials. If a spark or explosion does occur, the device effectively contains the resulting reaction. Furthermore, such cameras are specifically designed out of materials that either do not spark, resist or contain an internal explosion, and are rated to function in outdoor environments. While expensive, these security cameras are specifically designed to keep personnel and the surrounding equipment safe. They allow for the attainment of safety even when hazardous are present. A1 Security Cameras offers such devices by manufacturers like Axis, Hanwha Techwin, and Hikvision.

What security cameras are used with C1D2?

What is C1D2?

C1D2, or class 1, division 2, is a label that defines a location that regularly uses hazardous materials that are prone to be ignited but are kept explicitly in sealed containers or within the systems that use such materials. In such environments, the flammable or explosive materials are only in the open in the case of:

  • Accidents
  • Breakdowns
  • Leaks
  • Unintended consequence

As displayed, C1D2 lists environments where hazardous materials are not a regular feature in the open during normal processes. Furthermore, the volatile gasses or liquids are kept within systems or storage that features ventilation preventing ignition.

What security cameras are used with C1D2?

Depending on the environment, the best cameras for C1D2 environments are explosion-protected or explosion-proof security cameras. Such devices must be capable of containing an explosion or resulting fire internally while providing effective surveillance and integrating with the surrounding technology. In such an environment, there are options that may be wired or wireless, but we recommend that systems be hard-wired for better quality and defined as explosion-proof. Explosion-proof, as will be discussed below, is simply superior in keeping people safe but is more expensive and requires a more extensive installation process. A1 Security Cameras offers design help for home and business owners globally so you can implement the best possible security camera system.

Does Class 1 Div 2 require explosion-proof?

No, a class 1 division 2 environment does not necessarily require electronics of any kind that are considered explosion-proof. However, approved devices simply do not cause an explosion within the area if, in the case, there is a gas leak or will not ignite a fire when a leak occurs. Explosion-proof security cameras are typically the best way to implement surveillance while preventing sparks or ignitions from occurring. While explosion-protected devices may provide a suitable option for the specific environment, they will need to be approved by the appropriate official.

What is the difference between C1D1 and C1D2?

What is the difference between C1D1 and C1D2?

In the United States, C1D1 and C1D2 are based on classifications made by the National Fire Protection Association 70, better known as NFPA. In the case of the two classifications, a C1 or class 1 equals an area where the flammable substance present is vapors or gases. Alternatively, D1 and D2, also known as divisions, refer to whether the hazardous materials are present during normal circumstances. D1 means that the materials are present, D2 means the materials are stored safely with exposure being unusual.

In short, C1D1 means flammable vapors or gases are regularly present in the environment, while C1D2 means the same materials are not present openly in normal circumstances.

What is a C1D1 certification?

A C1D1 certification defines a device as appropriate for environments that regularly experience flammable gases or vapors during operation. Such electronic devices, like explosion-proof cameras, are designed to keep any sparks or ignition of surrounding gases internal. An example of this can be seen when such materials might enter into the internal environment of the camera. The camera will not outwardly explode but will contain it internally if one were to occur. While such an instance is not as expected, the safety measure will ultimately disable the camera or any electronic.

What is a C1D2 room?

A C1D2 room may be one that works explicitly with equipment using flammable gasses or vapors. Such spaces are regularly seen in industries that regularly use propane, petroleum, gas, and other combustible materials. As a result, it is not uncommon for C1D1 rooms to be surrounded by a C1D2 perimeter or space for safety.

Should I use explosion-proof or explosion-protected cameras?

Should I use explosion-proof or explosion-protected cameras?

For C1D1 or C1D2 environments, A1 Security Cameras will always suggest explosion-proof security cameras over explosion-protected. While both are available on our site, explosion-protected cameras are not built to benefit such hazard-prone areas where gases and vapors are present. Such devices are moreover designed to resist oncoming explosions but may not be insulated in a way that will protect them and the staff from a resulting explosion or fire. However, for either of these cameras and more, our team provides installations services for residents and business owners in Dallas Fort Worth, Texas.
