Commercial kitchens bustle with activity, resonating with the sizzle of pans and the enticing aroma of cooking. Yet, amid this culinary chaos, a silent threat lurks – carbon monoxide (CO). This blog explores the origins of carbon monoxide in commercial kitchens, the hazards it presents, and the pivotal role of carbon monoxide detection systems. Additionally, it examines how CGS (Canadian Gas Safety) combats this danger with innovative solutions.

How Carbon Monoxide is Produced in Commercial Kitchens:

Carbon monoxide emerges as a byproduct of incomplete combustion from carbon-based fuels like natural gas or propane, commonly utilized in kitchen appliances such as stoves, ovens, and grills. Insufficient ventilation and inadequate equipment maintenance can foster carbon monoxide accumulation in the atmosphere. Exposure to elevated levels of carbon monoxide can induce symptoms ranging from headaches and dizziness to unconsciousness and potentially fatal outcomes. Staff in commercial kitchens, who spend extended periods in these environments, face heightened vulnerability to carbon monoxide poisoning.

The Importance of Carbon Monoxide Detection:

Detecting carbon monoxide is critical to safeguarding kitchen staff and customers alike. Early detection facilitates prompt intervention, mitigating health risks and ensuring adherence to safety protocols.

The CGS Solution:

CGS offers a suite of carbon monoxide detection and ventilation interlock systems tailored specifically for commercial kitchens. One notable example is the Merlin 1500S, which serves as an interlock between the ventilation system and the gas solenoid valve. This system ensures that the gas solenoid remains closed unless the ventilation system operates effectively, thus minimizing the potential for carbon monoxide buildup. In the event of elevated CO levels, the Merlin 1500S triggers visual and audible alarms while automatically shutting down the gas supply.

The CGS product line includes features like fan interlocking, compatibility with gas detectors, integration with remote emergency shut-off buttons, and straightforward installation and calibration procedures. The Merlin 1500S is backed by a comprehensive 3-year warranty, providing users with peace of mind.


Protecting kitchen staff and patrons from carbon monoxide hazards is paramount in commercial kitchen environments. With advanced solutions from CGS, such as the Merlin 1500S, we can ensure proactive measures are in place to mitigate risks effectively.
