Proper ventilation in boiler rooms is crucial primarily to ensure there is sufficient oxygen for combustion and to prevent the buildup of hazardous gases. Boilers rely on combustion to generate steam or hot water, and this process requires an adequate supply of oxygen. If the ventilation is insufficient, the combustion process may become inefficient, leading to incomplete combustion, which can produce carbon monoxide and other dangerous gases.

Furthermore, inadequate ventilation can create an unsafe environment by allowing harmful gases to accumulate, posing serious health risks to personnel working in or around the boiler room. Therefore, maintaining proper ventilation is essential for safety and efficiency, preventing hazardous conditions while also ensuring that the combustion process operates effectively.

This highlights the importance of oxygen levels and air quality in ensuring not just the performance of the boiler, but also the safety of the facility and its workers.
