2. Chlorine gas poisoning - Wikipedia

   en.wikipedia.org/wiki/Chlorine_gas_poisoning

   Chlorine gas poisoning is an illness resulting from the effects of exposure to chlorine beyond the threshold limit value. Acute chlorine gas poisoning primarily affects the respiratory system , causing difficulty breathing, cough, irritation of the eyes, nose, and throat, and sometimes skin irritation .

3. List of highly toxic gases - Wikipedia

   en.wikipedia.org/wiki/List_of_highly_toxic_gases

   Highly Toxic: a gas that has a LC 50 in air of 200 ppm or less. [2] NFPA 704: Materials that, under emergency conditions, can cause serious or permanent injury are given a Health Hazard rating of 3. Their acute inhalation toxicity corresponds to those vapors or gases having LC 50 values greater than 1,000 ppm but less than or equal to 3,000 ppm ...

4. Chloroform - Wikipedia

   en.wikipedia.org/wiki/Chloroform

   The chloroform molecule can be viewed as a methane molecule with three hydrogen atoms replaced with three chlorine atoms, leaving a single hydrogen atom. The name "chloroform" is a portmanteau of terchloride (tertiary chloride, a trichloride) and formyle, an obsolete name for the methylylidene radical (CH) derived from formic acid. [citation ...

6. Gas detector - Wikipedia

   en.wikipedia.org/wiki/Gas_detector

   A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals. Gas detectors can be used to detect combustible, flammable and toxic gases, and oxygen depletion.

7. Chemical cartridge - Wikipedia

   en.wikipedia.org/wiki/Chemical_cartridge

   Combined, or multi-gas canisters and cartridges protect from harmful gases by using multiple sorbents or catalysts. An example is ASZM-TEDA Carbon canister used in CBRN masks by the US Army . This is a form of activated carbon saturated with copper, zinc, silver, and molybdenum compounds, as well as with triethylenediamine (TEDA).

8. 1,1,1-Trichloroethane - Wikipedia

   en.wikipedia.org/wiki/1,1,1-Trichloroethane

   The organic compound 1,1,1-trichloroethane, also known as methyl chloroform and chlorothene, is a chloroalkane with the chemical formula CH 3 CCl 3. It is an isomer of 1,1,2-trichloroethane . A colourless and sweet-smelling liquid, it was once produced industrially in large quantities for use as a solvent . [ 5 ]

9. Phosgene - Wikipedia

   en.wikipedia.org/wiki/Phosgene

   The odor detection threshold for phosgene is 0.4 ppm, four times the threshold limit value (time weighted average). Its high toxicity arises from the action of the phosgene on the −OH , −NH 2 and −SH groups of the proteins in pulmonary alveoli (the site of gas exchange), respectively forming ester, amide and thioester functional groups in ...
