CO₂ Monitoring System Requirements in Arizona – What You Need to Know in 2025

If your Arizona business uses carbon dioxide (CO₂) tanks — whether for beverage dispensing, cryogenics, or brewing — updated compliance with CO₂ safety monitoring systems is essential. At Global Systems United, we specialize in designing, installing, and servicing CO₂ monitoring systems that meet the latest Arizona Fire Code requirements.

We proudly serve businesses throughout Phoenix, Tucson, Mesa, Chandler, Scottsdale, Glendale, Gilbert, Tempe, Peoria, Surprise, Avondale, Goodyear, Flagstaff, Yuma, Prescott, Sierra Vista, Casa Grande, Lake Havasu City, Queen Creek, and Maricopa.

Why CO₂ Monitoring Systems Are Critical
Carbon dioxide is odorless and invisible — but in enclosed areas, it can reach dangerous levels quickly. That’s why the 2022 and 2024 International Fire Code (IFC) updates — enforced throughout Arizona — require continuous CO₂ monitoring with alarms and ventilation triggers.

Industries affected:
Restaurants and Fast-Casual Chains
Breweries and Bars
Cannabis Extraction Labs
Medical and Dental Gas Supply
Beverage Distributors
Food Production Facilities

Arizona CO₂ Requirements at a Glance
Threshold: Monitoring required if CO₂ storage exceeds 100 lbs.
Alarms: Trigger at 5,000 ppm (warning) and 30,000 ppm (evacuation)
Display: Digital readout visible outside storage area
Placement: Sensors 12–18 inches above floor near CO₂ source
Alarms: Audible/visual alarm required in occupied spaces
Ventilation: Must activate automatically at high CO₂ levels

Fire departments across Phoenix, Tempe, and Scottsdale have been particularly strict in enforcing these standards. Our team understands what each AHJ looks for and helps you pass inspection the first time.
