The smoke alarm is required as a control for which of the following?

The smoke alarm serves as a critical device for monitoring combustion processes and air quality, making it a vital control mechanism in relation to combustion and air pollution. When a smoke alarm detects smoke particles in the air—an indication of incomplete combustion or potential fire—it signals an alarm that can alert occupants to take action. This early warning system helps to ensure safety by indicating that conditions may be hazardous due to possible combustion issues, which could lead to air pollution if not addressed.

While fire prevention is certainly a crucial aspect of safety protocols, smoke alarms specifically focus on detecting the byproducts of combustion, which ties directly to the concept of combustion and its impact on air quality. Pressure regulation and fuel efficiency are important in burner operations but do not directly pertain to the primary function of smoke alarms.
