What is C1D1?

The terms C1D1, CID1, Class I, Division 1 get thrown around quite a bit in the extraction industry, but what does it mean, and to what does it refer? Class I, Division 1 spaces are, as defined by NFPA 70:

“a Class I, Division 1 location shall be any location where one of the following conditions exists:

(1) An ignitable concentration of flammable gas or vapor can exist under normal operating conditions.

(2) An ignitable concentration of flammable gas or vapor can exist frequently because of repair or maintenance operations or because of leakage.

(3) Breakdown or faulty operation of equipment or processes might release an ignitable concentration of flammable gas or vapor and might also cause simultaneous failure of electrical equipment in such a way as to directly cause the electrical equipment to become a source of ignition.”

 

For typical hydrocarbon extraction processes, an ignitable concentration of flammable gas can be present under normal conditions. (opening the collection vessel, off gassing, depressurization) This is why a Class I, Division 1 space is required by AHJs in the vast majority of, if not all, regulated markets.

 

Sounds scary and technical, right? Not really.

 

Once you fully understand a problem you can create a solution to mitigate risks and reduce downside. The HAL Extraction Booth does just that.

Since there will be flammable concentrations;

You will need to dilute and evacuate that atmosphere.

We provide an efficient ventilation system, with multiple atmospheric concentrations dependent ventilation, that provides the safest Class I, Division 1 location for butane and propane extraction.

You will need explosion-proof components rated for a Class I, Division 1 environment.

All our components inside of the space are rated for use in this hazardous environment.

You will need to know what the flammable concentrations are at any given time.

We provide interior and exterior live read-outs of atmospheric concentrations.

You will need a system that analyses and reacts to those atmospheric conditions.

We provide a patent-pending solution that provides adaptive ventilation and reactive alarms to mitigate potential flammable atmospheric concentrations.

You will need a fire suppression system to put out a fire in the event of catastrophic failure.

Most industrial spaces already have a building wide water-based sprinkler system, and it is much more cost effective to drop in sprinklers from that system into the HAL Extraction Booth. If your facility does not have a water-based sprinkler system. We can coordinate the installation of an automatic stand-alone fire suppression system for an additional fee.

 

 

This is just another way that HAL Extraction is keeping people safe!
