What types of injuries can improper SCBA use lead to?

Improper use of SCBA can lead to serious respiratory issues, such as respiratory distress, because an SCBA is designed to provide clean air in environments where contamination may exist. If the SCBA is not fitted correctly or is malfunctioning, the user may inhale toxic substances, resulting in respiratory problems. Hearing loss could stem from loud environments frequently encountered during emergency operations, combined with the potential for improper use of communication devices. Heat exhaustion is also a risk since wearing SCBA involves additional weight and insulation, which can hinder the body's ability to regulate temperature during physically demanding tasks, especially in hot conditions.

The option correctly identifies a range of potential complications that can arise specifically from improper use of SCBA, highlighting the importance of training and proper equipment handling for safety in hazardous environments. Other options discuss injuries that may occur in different contexts, but they do not directly relate to the functions and risks associated with the use of SCBA. For instance, muscle strains and joint pain usually result from physical exertion without the primary concerns being the breathing apparatus itself. Similarly, skin irritations and fractures relate to different hazards that might not be linked to SCBA use. Therefore, understanding the specific risks linked to SCBA can help in ensuring safety and functionality during firefighting and
