Inhalation injury may occur during workplace accidents and residential fires, with the latter being far more common. In the UK in 2020, there were four cases of inhalation accidents in the work place, as measured by the Surveillance of Work-Related and Occupational Respiratory Disease (SWORD) group.[4]The Health and Occupation Research Network. Annual Report: the incidence of work-related ill-health as reported to The Health and Occupation Research (THOR) network by physicians in the Republic of Ireland between 2005 and 2020. May 2020 [internet publication].

In the US in 2019, there were 59 fatal and 3360 non-fatal injuries in private industry, the majority from chemical exposure.[5]US Bureau of Labor Statistics. Injuries, illnesses, and fatalities.

Public servants such as firefighters and police officers are estimated to have much higher rates of non-fatal inhalation injury, largely due to their role as first responders in fires.[7]Henneberger PK, Metayer C, Layne LA, et al. Nonfatal work-related inhalations: surveillance data from hospital emergency departments, 1995-1996. Am J Ind Med. 2000 Aug;38(2):140-8.

Inhalation injuries tend to occur in workplaces where the workforce is predominantly young and male, and the demographics of injury reflect this.
In 2019, people aged 50 to 54 years were at greatest risk for fire injury in the US (66.4 injuries per million population); children aged 5 to 9 years were at lowest risk (18.8 injuries per million population).[8]US Fire Administration. US fire deaths, fire death rates and risk of dying in a fire (2010 - 2019). May 2021 [internet publication].

Of a total of 3515 fire deaths, approximately 62% occurred in males (2164 deaths), compared with 38% in females (1351 deaths).[8]US Fire Administration. US fire deaths, fire death rates and risk of dying in a fire (2010 - 2019). May 2021 [internet publication].

African American males and American Indian males had the highest fire death rates per million population (19.1 and 18.7, respectively).[8]US Fire Administration. US fire deaths, fire death rates and risk of dying in a fire (2010 - 2019). May 2021 [internet publication].

The majority of fire-related deaths are believed to be due to respiratory system injury, a strong predictor of mortality among burn patients.[9]Colohan SM. Predicting prognosis in thermal burns with associated inhalational injury: a systematic review of prognostic factors in adult burn victims. J Burn Care Res. 2010 Jul-Aug;31(4):529-39.

While the US has had roughly 4000 fire-related deaths annually for several years, this marks a significant improvement from the 12,000 annual fire-related deaths circa 1980.
