Which factor is NOT typically checked by a boiler operator upon entering the boiler room?

In the context of a boiler operator's duties when entering the boiler room, air quality is typically not one of the immediate factors that operators check. The primary focus upon entering the room is to ensure safe and efficient operation of the boiler itself. This involves monitoring critical parameters directly related to boiler function, such as water levels, which ensure that the boiler has sufficient water to operate safely; flame conditions, which confirm that combustion is occurring properly; and steam pressures, which are crucial for maintaining the desired output and safety protocols.

While air quality can be an important consideration for overall safety and working conditions, monitoring it is generally not an immediate priority compared to the mechanical and operational checks. Operators will more likely perform air quality assessments periodically or as part of safety protocols rather than as a routine check upon entering the boiler room.
