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 ...
In 2014, the American Association of Poison Control Centers reported about 6,000 exposures to chlorine gas in the US in 2013, compared with 13,600 exposures to carbon monoxide, which was the most common poison gas exposure; [7] the year before they reported about 5,500 cases of chlorine gas poisoning compared with around 14,300 cases of carbon ...

[61] 95% of carbon monoxide poisoning deaths in Australia are due to gas space heaters. [62] [63] In many industrialized countries, carbon monoxide is the cause of more than 50% of fatal poisonings. [11] In the United States, approximately 200 people die each year from carbon monoxide poisoning associated with home fuel-burning heating ...
Nitrogen dioxide poisoning is the illness resulting from the toxic effect of nitrogen dioxide (NO 2). It usually occurs after the inhalation of the gas beyond the threshold limit value. [1] Nitrogen dioxide is reddish-brown with a very harsh smell at high concentrations, at lower concentrations it is colorless but may still have a harsh odour.
Cyanide poisoning inhibits aerobic respiration and therefore increases anaerobic glycolysis which causes a rise of lactate in the plasma. A lactate concentration above 10 mmol per liter is an indicator of cyanide poisoning, as defined by the presence of a blood cyanide concentration above 40 μmol per liter.
The annual meeting of member states of the global chemical weapons watchdog on Thursday called on countries to prevent the sale or transfer to Syria of raw materials and equipment that could be ...
Phosgene is an insidious poison as the odor may not be noticed and symptoms may be slow to appear. [31] At low concentrations, phosgene may have a pleasant odor of freshly mown hay or green corn, [32] but has also been described as sweet, like rotten banana peels.
