What are the second and third most common causes of injury-related deaths in firefighting?

The answer is supported by the understanding that in firefighting, the risks posed by being struck by an object and asphyxiation or burns are significant contributors to injury-related deaths. Firefighters often work in hazardous environments where falling debris can lead to being struck, particularly during structural firefighting where building integrity may be compromised. Furthermore, asphyxiation can occur due to smoke inhalation, which is a common danger during firefighting operations. Burns are also a critical risk, as contact with flames or hot materials is inherent to the job.

Thus, being struck by an object ranks as a common cause of injury-related fatalities due to the physical dangers present at fire scenes. Additionally, the risks of asphyxiation or burns combine the two key dangers firefighters face during operations, making this combination particularly crucial in discussing injury-related fatalities in the firefighting profession. The presence of smoke and toxic gases exacerbates the risks, leading to both asphyxiation and burn injuries.

In contrast, other potential answers may represent less common causes or focus on different types of dangers that do not hold the same prevalence in firefighting fatalities.
