Which of the following is NOT a typical firefighter injury?

Vision impairment is not typically categorized as a common injury sustained by firefighters during their operations. Firefighters frequently face a range of injuries related to the physically demanding and hazardous nature of their job. This includes sprains and strains, which can occur due to the heavy lifting and strenuous activities involved in firefighting. Burns are a well-known risk due to exposure to flames and heat. Cardiac arrest is also represented among firefighter health concerns because of the intense physical exertion and stress encountered in emergency situations.

In contrast, while vision impairment can occur due to various reasons, it is not an inherent risk of firefighting in the same manner as the other options. The focus of firefighter injuries generally revolves around acute physical trauma rather than gradual deterioration of vision, marking vision impairment as less typical in the context of immediate firefighting injuries.
