Carbon Dioxide (CO2) is a gas that is present in small quantities in the air we breathe. About 400 Parts Per Million (PPM). CO2 is widely used in the beverage and cannabis industries and can be extremely dangerous if not used properly. The latest revision of the International Fire Code (IFC 2015) requires any site using Carbon Dioxide to have a CO2 gas detection system. This code also requires a notification or alarm when the atmospheric CO2 concentration reaches 5,000ppm. Proper monitoring equipment is the only way to know if you have 400ppm or 10,000ppm.


Whether you are enriching a plant growing atmosphere with CO2, brewing beer, or have a restaurant, our team will help to keep you safe and compliant.


Call us today for assistance with system design or to evaluate your existing system for compliance with your local IFC 2015 based codes. 


Carbon Dioxide (CO₂) Safety and Compliance

  • Carbon Dioxide (CO₂) is naturally present in the air at concentrations around 400 parts per million (ppm). While essential in many industries—including breweries, restaurants, cannabis grow operations, food processing, and laboratories—CO₂ can become dangerous when stored or used in enclosed or poorly ventilated spaces.
  • Under the 2024 International Fire Code (IFC), any facility using or storing compressed CO₂ (especially in cylinders or bulk systems) must install continuous gas detection systems. These detectors must trigger visible and/or audible alarms when concentrations reach 5,000 ppm, in accordance with OSHA 29 CFR 1910.1000 exposure limits.
  • Depending on your system's volume and location, you may also be required to install: 
  • Mechanical ventilation or exhaust systems
  • Warning signage
  • Emergency shut-off switches
  • Automated system controls with interlocks
  • Additional requirements may apply based on NFPA 55 (2023 Edition) and CGA standards (P-1, G-6.5, and C-6.4), which outline best practices for system design, component integrity, inspections, and safe handling procedures.

Smart System Integration with SGS Safe Touch Pro™

At Safe Gas Systems, we offer SGS Safe Touch Pro™—a purpose-built control system that fully integrates:

  • CO₂ gas detection
  • Oxygen deficiency monitoring
  • Emergency exhaust fan activation
  • Warning strobes and alarms
  • Manual and automatic system shutdown controls
  • Fire alarm panel interfacing

These features not only simplify code compliance, but also enhance safety, improve system visibility, and allow for remote monitoring and response.

Code Inspections & Safety Audits 

We also provide on-site inspections and compliance audits to ensure your existing CO₂ systems meet the latest IFC, OSHA, CGA, and NFPA standards. Whether you're installing a new system or upgrading an existing one, our team ensures that every component—controls, sensors, ventilation, piping, and storage—is properly installed, labeled, and functional.
