Gas leaks in boiler rooms pose a significant threat to both property and lives. These leaks can lead to catastrophic explosions or fires if not promptly detected and addressed. Automatic gas shut-off systems are a critical component of boiler room safety, providing an effective means of preventing gas leaks and mitigating their potential consequences.

How and Why Gas Leaks Form in a Boiler Room:

Gas leaks in boiler rooms can occur due to various factors, including faulty equipment, deteriorating piping, or human error during maintenance or installation. Additionally, natural gas, commonly used in boiler systems, is odorless and colorless, making leaks difficult to detect without specialized equipment. As gas leaks are formed, the potential for ignition increases, posing a severe risk to anyone in the vicinity.

The Dangers of Gas Leaks

Gas leaks in boiler rooms pose serious risks, including explosions, fires, and carbon monoxide poisoning. Past incidents, such as the 2010 Kleen Energy Plant explosion in Connecticut, serve as stark reminders of the devastating consequences of gas leaks in industrial settings. These incidents result in loss of life, extensive property damage, and significant financial repercussions.

What is a Carbon Monoxide Boiler Interlock?:

A carbon monoxide boiler interlock, such as the Mini Merlin CO Interlock from AGS, is a safety device designed to detect the presence of carbon monoxide in boiler rooms and automatically shut off gas supply to the boiler. By swiftly responding to CO leaks, these interlock systems prevent gas buildup and reduce the risk of fire or explosion.


Gas leak prevention is paramount in boiler rooms to safeguard lives and property. Automatic gas shut-off systems, like the Mini Merlin CO Interlock from AGS, provide an essential layer of protection against the dangers of gas leaks. By investing in reliable safety equipment and implementing proactive safety measures, boiler room operators can minimize the risk of catastrophic incidents and ensure a safe working environment for all.
