The following Toxic and Combustible Gas Charts include data that are used as guidelines for establishing health and safety standards for various gases and vapors. Information, including TLV/TWA, IDLH and LEL values are used by ENMET to determine the appropriate range and alarm points for each gas. Relative Gas Densities are also given. Knowing the density of a gas or vapor, relative to air, is useful in deciding the best sampling location. It is important to know if the target gas will typically (excluding environmental factors of ventilation, wind, etc.) tend to rise, fall or mix uniformly in the area being monitored.
ENMET can design custom engineered gas and vapor detection systems for clients who need to monitor the contents of pipelines, ducts, process lines, storage tank headspaces, engine test cells, environmental chambers, and vehicle maintenance areas. Using diverse sensor technology such as infrared, photoization, catalytic combustion, metal oxide semiconductor (MOS), and electro-chemical, it is possible to design systems for explosive levels, CO2 and oxygen levels, VOC’s, refrigerants and chlorinated solvents, as well as common inorganic toxic gases such as CO, H2S, Cl2, NH3, NO, NO2, SO2, HCl, HF, and ozone.
Pressurized process lines can be flow-controlled to deliver a gas stream sample to our multi-sensor platform, the ProAir- 2200. Alternately, a internal sample pump panel, the GSM-60 can be used to extract a sample stream from duct work, headspaces, fuel storage areas, and environmental test chambers.
