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]
Intentional traffic collisions may be a chosen method of suicide where speed limits are high enough to produce fatal deceleration. [2] Modern cars have high rates of acceleration and can easily reach very high speeds in short distances, while most cannot protect occupants in frontal impact collisions exceeding 70 km/h (43 mph).

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.
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.”
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
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]
Depending on the type and amount of irritant gas inhaled, victims can experience symptoms ranging from minor respiratory discomfort to acute airway and lung injury and even death. A common response cascade to a variety of irritant gases includes inflammation , edema and epithelial sloughing , which if left untreated can result in scar formation ...
Days after a massive fire erupted under the 10 Freeway in downtown Los Angeles, the resulting closure has exacerbated traffic in nearby neighborhoods such as Boyle Heights.
