Suicide by carbon monoxide poisoning may be attempted by running the engine in an enclosed garage, or by piping the exhaust gas into the driver's compartment with a hose, but catalytic converters required for air quality regulations eliminate over 99% of carbon monoxide produced.
Idling automobiles with the exhaust pipe blocked by snow has led to the poisoning of car occupants. [83] Any perforation between the exhaust manifold and shroud can result in exhaust gases reaching the cabin. Generators and propulsion engines on boats, notably houseboats, have resulted in fatal carbon monoxide exposures. [84] [85]
Smoke inhalation is the breathing in of harmful fumes (produced as by-products of combusting substances) through the respiratory tract. [1] This can cause smoke inhalation injury (subtype of acute inhalation injury) which is damage to the respiratory tract caused by chemical and/or heat exposure, as well as possible systemic toxicity after smoke inhalation.
He was later pronounced dead, aged 27. The police ultimately ruled his death a suicide through the earlier text messages sent to his sister, after the discovery of charcoal briquette remnants in a frying pan at the scene. [12] [13] Du Yuwei, an ex-member of GNZ48, ended her life on 16 October 2018 using this method. [14]
A lot of the time they test you for CO2, which can be an indication of exposure,” he said. “What we would like to do is to develop a test that would prove that you have been exposed.”
Exposure to high level of nitrogen dioxide may lead to inflammation of the mucous membrane and the lower and upper respiratory tracts. [11] The symptoms of acute nitrogen dioxide poisoning is non-specific and have a semblance with ammonia gas poisoning, chlorine gas poisoning, and carbon monoxide poisoning.
This is the simplest and probably the most accurate method, but can only be used where the smoke concentration is slight, as the filter can quickly become blocked. [ 65 ] The ASTM smoke pump is a simple and widely used method of in-line capture where a measured volume of smoke is pulled through a filter paper and the dark spot so formed is ...
An asphyxiant gas, also known as a simple asphyxiant, is a nontoxic or minimally toxic gas which reduces or displaces the normal oxygen concentration in breathing air. ...
