CO2 monitoring in Las Vegas

CO2 monitoring in Las Vegas follows the Southern Nevada fire code: Clark County adopted the 2024 International Fire Code with the Southern Nevada amendments in December 2025 (Ordinance 5321), and the City of Las Vegas publishes the same amendments with its own. Those amendments tighten the CO2 rules in two specific ways, and we install to them.

Two Southern Nevada CO2 amendments to know

First, a construction permit is required to install or substantially modify a beverage dispensing system that uses CO2 above the amounts in the permit table, 875 cubic feet, or about 100 pounds. Second, the gas detection section for insulated CO2 systems is amended so the 30,000 ppm alarm also stops the flow of CO2 into the piping, on top of the 5,000 ppm supervisory alarm.

The Strip itself sits in unincorporated Clark County rather than the City of Las Vegas, so which jurisdiction reviews your system depends on your address. We confirm it before specifying anything.

Life safety

Fitting a CO2 alarm in Las Vegas venues

CO2 is heavier than air, so a CO2 alarm in Las Vegas cellars, keg rooms and back-of-house storage goes low, within about a foot of the floor where gas collects. The LogiCO2 MK9 shuts off the supply at 5,000 ppm and drives strobe and horn outputs, which matters in loud venues where a horn alone can go unheard.

A central unit links up to 12 sensors, so a resort outlet with several rooms is one system.

A CO2 detector in Las Vegas is not a CO detector

Many searches for a CO2 detector in Las Vegas are really for a home carbon monoxide alarm. A commercial CO2 sensor measures carbon dioxide in parts per million and controls a shutoff, which is what a fire inspector expects in a commercial gas room.

  • Sensors at floor level, placed by survey
  • Life-safety shutoff at 5,000 ppm
  • Strobe and horn outputs for loud venues
  • Permit and inspection documentation
  • Sensor servicing and replacement on the account

Monitoring in large venues and resort outlets

A resort food and beverage outlet often stores CO2 in one back-of-house room and pours it in several bars, with long lines running through service corridors and ceilings. The gas risk follows the lines, so the survey follows them too: storage rooms, keg rooms, any below-grade space a line passes through, and the places staff work alone.

In a loud bar a horn alone can go unheard, which is why the MK9's strobe output matters here. The visible alarm is part of the design, not an extra.

  • CO2 and keg storage rooms
  • Below-grade corridors carrying distribution lines
  • Walk-in coolers behind each bar
  • Rooms where staff change cylinders or work alone

Permit and inspection paperwork in Southern Nevada

Where a construction permit is required under the Southern Nevada amendments, the fire code official reviews the system before it is installed or substantially modified. We prepare the details that review needs: the CO2 quantity, storage location, equipment, sensor positions and heights, alarm thresholds and the shutoff arrangement.

Henderson and Pahrump took part in drafting the Southern Nevada amendments along with Clark County and the City of Las Vegas, which is why the CO2 rules look similar across the valley. Each jurisdiction still adopts and enforces them itself, so we confirm with yours.

Common questions

Under the Southern Nevada amendments, a construction permit is needed for beverage dispensing systems using CO2 above about 100 pounds (875 cubic feet). Your fire code official confirms what applies to your site.

The Strip is in unincorporated Clark County. Downtown and Fremont Street are in the City of Las Vegas. Both use the Southern Nevada amendments to the 2024 International Fire Code.

Yes. They drift and eventually need replacing, which we handle as a maintenance item.

Yes, both are in our Las Vegas service area. Each city enforces its own adoption of the fire code, so we confirm the local requirements before specifying.
