As The Gas Detection Experts, Critical Environment Technologies (CET) want to make your life easier when it comes to figuring out what gas detection system you need for your project. Each project is different, even if it’s the same type of application.
Parking garages for example differ in size, placement of columns, walls and other obstacles, and entrances, exits and ventilation equipment vary in type and location. These variables impact how many sensors are required, where they need to be installed, whether zoning is required and the possible need for additional hardware like relays, analog outputs, power supplies, etc.

Chlorine gas, also known as bertholite, can pose serious, even deadly, health hazards. The gas reacts with water in the lungs to form hydrochloric acid, which destroys living tissue. Chlorine has been used as a weapon during times of war. Its first documented use was on April 22, 1915 during World War I. In more recent times, the gas was reportedly used in Middle East conflicts in the 1990s and 2000s.
