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 2022, there were 49 fatal occupational inhalational injuries according to the US Bureau of Labor Statistics.[5]Bureau of Labor Statistics (US Department of Labor). National census of fatal occupational injuries in 2022. Dec 2023 [internet publication].

The rates of non-fatal occupational inhalational injuries are likely underestimated.[6]Hendricks KJ, Layne LA, Schleiff PL, et al. Surveillance of acute nonfatal occupational inhalation injuries treated in US hospital emergency departments, 2014-2017. Am J Ind Med. 2022 Aug;65(8):690-6.

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.

Approximately 6000-7000 inhalational injuries occur in firefighters every year, although this is likely an underestimate.[8]Kahn SA, Bader B, Flamm T, et al. Revisions in the national burn repository improve the rate of firefighter injury data capture. J Burn Care Res. 2019 Jun 21;40(4):412-5.

Inhalation injuries tend to occur in workplaces where the workforce is predominantly young and male, and the demographics of injury reflect this.
Overall, fire deaths increased from 2012 to 2022 from 10.5 deaths per million population to 13.3 deaths per million population; but this rate remains lower than in 2000 when there were 14.8 deaths per million population.[9]U.S Fire Administration. Fire death and injury risk. Apr 2025 [internet publication].

In 2022, people aged 85 years or older were at greatest risk for fire death in the US (relative risk 3.7); children aged 10-14 years were at lowest risk (relative risk 0.2).[9]U.S Fire Administration. Fire death and injury risk. Apr 2025 [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.[10]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.
