Which of the following is a safety concern associated with a compressor used in supplied air systems?

A critical safety concern associated with compressors used in supplied air systems is the need for a carbon monoxide alarm. This is because compressors, especially those that are gasoline or diesel-powered, can potentially introduce carbon monoxide into the breathable air supply. Carbon monoxide is a colorless and odorless gas that can lead to serious health issues or even death if inhaled in sufficient quantities. Implementing a carbon monoxide alarm ensures that any presence of this hazardous gas is detected promptly, allowing for immediate corrective actions to be taken. This safeguard is essential in maintaining the safety and health of workers who rely on supplied air systems in environments where pollutants may be present.

While backup power sources, portability, and the ability to handle extreme temperatures may also be important considerations for a compressor's functionality and performance, the direct link between carbon monoxide exposure and safety makes the presence of a carbon monoxide alarm a top priority in this context.
