What is the first thing you should check when entering a boiler room?

When entering a boiler room, the first thing to check is the water level. The water level is critical for the safe operation of a boiler; it ensures that there is enough water to prevent overheating and damage to the boiler. If the water level is too low, it can lead to serious safety hazards, including boiler failure or explosion, which can result in significant damage and endanger lives.

Monitoring the water level also helps in maintaining the proper steam pressure and temperature. Therefore, verifying the water level upon entering the boiler room is essential for assessing the boiler's operational safety and performance. This is a fundamental practice for any operator to ensure the boiler operates within safe parameters.
