Chlorine Cl2 Gas Detection & Gas Detectors
Chlorine (Cl2) is a naturally occurring, highly reactive gas found in various industrial settings where it is used for production and disinfectant. The name Chlorine is derived from chloros, meaning green, referring to the color of the gas. It is 2.5 times as heavy as air, has an intensely disagreeable suffocating odor and is very poisonous.
Typical applications where dangerous levels of Chlorine (Cl2) might occur and benefit from a Chlorine gas detector are:
- Chlorine manufacturers
- Manufacturers using Chlorine in organic and inorganic synthesis (solvents, antifreeze, polymers, pesticides, refrigerants, rocket fuel)
- Metal manufacturing
- Areas using chlorine as a disinfectant (drinking water, sewage, swimming pools)
- Pulp and Paper production
- Pharmaceuticals and cosmetics manufacturing
Chlorine irritates the respiratory system in extremely low levels.
Exposure Limits (Source: OSHA)
Following are Chlorine exposure limits that industries should be aware of when researching Chlorine gas detectors and gas detection systems.
|OSHA PEL (General Industry)||1 ppm (ceiling)|
|OSHA PEL (Maritime)||1 ppm TWA|
|ACGIH TLV||0.5 ppm TWA, 1.0 ppm STEL|
|NIOSH REL||0.5 ppm TWA, 1.0 ppm STEL|
|NIOSH IDLH||10 ppm|
- TWA = Time Weighted Average exposure concentration for a normal 8-hour workday and 40-hour workweek
- STEL = Short Term Exposure Limit (Usually a 15-minute time-weighted average exposure that should not be exceeded at any time during a workday
- NIOSH (National Institute for Occupational Safety and Health)
- REL = Recommended Exposure Limit
- IDLH = Immediately Dangerous to Life or Health Concentration
- OSHA (Occupational Safety and Health Administration)
- PEL = Permissible Exposure Limit
- ACGIH (American Conference of Government Industrial Hygienists)
- TLV = Threshold Limit Value
Sierra Monitor has several different Chlorine gas detectors dependent upon the application.
