International Fire Code 5307 Carbon Dioxide (CO2)
The 2018 edition of the International Fire Code (IFC) now requires mechanical ventilation or an emergency alarm system when the quantity of CO2 exceeds 100 pounds.
- 5307.3.2 Emergency alarm system
- 5307.3.2 Gas detection system
Where ventilation is not provided in accordance with Section 5307.3.1, a gas detection system shall be provided in rooms or indoor areas and in below-grade outdoor locations with insulated carbon dioxide systems. Carbon dioxide sensors shall be provided within 12 inches (305 mm) of the floor in the area where the gas is expected to accumulate or other approved locations.
The system shall be designed as follows:
- Activates an audible and visible supervisory alarm at a normally attended location upon detection of a carbon dioxide
concentration of 5,000 ppm (0.5% by vol.). - Activates an audible and visible alarm within the room or immediate area where the system is installed upon detection of
a carbon dioxide concentration of 30,000 ppm (3% by vol.).
Although the 2018 IFC contains new language regarding CO2 systems please check with your local government units of the status of this code in your area.
