CO2 Safety Monitor Installation Tips

co2 gas safety monitor

Properly placing carbon dioxide gas monitoring alarms during installation cannot be underestimated. Serious thought should be put into planning the placement, electrical wiring, careful protection of devices as well as how to train employees about the devices and what to do if they go off. In every instance a risk assessment is the initial key to safety.

There are 2 parts to every CO2 monitor and safety alarm:

  1. CO2 sensor
  2. Remote display

Note that while both of these devices include audible and visual alarms, they need to be installed differently.

Installing the CO2 Sensor

Your site assessment should consider four factors to insure proper installation of the systems.

Prior to your site assessment we recommend that you inquire about and understand the local and state codes that may now require specific additions to monitors.  Adding strobe lights for additional visual notification is the most common addition.  Some jurisdictions are also requiring that monitors be tied to the fire alarm panel to trigger an automatic call to the local Fire Department to warn of a CO2 leak.  Meeting these new requirements is not optional,  You will be fined if these requirements are not met.

Different applications allow for different coverage areas.

Enclosed Beverage Systems - In these applications monitors cover approx. 1,250 sq. feet (length x width of the space). Typically, placement within 10 feet of the bulk CO2 storage tank, cylinders, and the BIB rack is sufficient. Larger spaces may require additional monitors. Enclosed rooms/spaces (closets, offices, bathrooms, and keg coolers) may require additional monitoring as gas can be trapped in these spaces because of the enclosure.

Purposefully Enriched Areas

Applications where CO2 is intentionally injected into a space (called enrichment) will allow for larger coverage areas. Indoor Agriculture usage will allow for larger coverage areas because of the continuous circulation of the environment. In these applications a gas detection monitor can effectively cover less than 2,000 sq. feet (length x width of the space). 

However, each installation should be considered individually to account for the particular layout and any varying or enclosed spaces within the footprint.

Where Should the Carbon Dioxide (CO2) Sensor be Mounted?

Once you know the approximate location of the sensors, the confined space, and how many you'll require, the next step is to determine where to mount them. 

Think of CO2 flowing like water. Water will fill a cup from the bottom upwards.  The same will happen in interior spaces like draft coolers, restaurants, breweries, and grow facilities. Because the CO2 gas is heavier than normal air it will flow down stairs or collect in low lying areas first. For this reason, the CO2 sensor unit should be mounted no higher than 12-18 inches (45-60 cm) above the floor.

The next consideration is power. While our CO2 Safety Monitors use a 110-220 VAC 50/60 Hz to 12VDC power, a 24 VDC hard-wired power option is available if normal wall power is not readily available. The important thing to remember is that the CO2 Sensor should be mounted in such a way that it cannot be accidentally damaged when moving boxes, crates or gas cylinders nearby. In addition, if using the power adapter insure that the plug is secured to the wall to insure staff does not accidentally or purposefully unplug the alarm.

Installing the CO2 Remote Display

Both the CO2 Sensor unit and remote display unit have audible and visual alarms. However, while the CO2 Sensor monitors in an enclosed area where a potential CO2 leak could occur, the Remote Display is designed to be mounted outside the space and to warn staff of a potential gas leak before entering the area. 

Remote displays are best mounted at eye level near the door frame of any door entering the enclosed area. They should be mounted on the same side as the door handle to insure they are not covered when the door is open. 

Our CO2 Safety Monitors have the ability to daisy-chain up to 3 remote displays to a single CO2 sensor unit. If their are more than 3 entry doors, a second CO2 sensor unit will be required.

Safety Signage

Once the CO2 Sensor Unit and Remote Display(s) are installed, you should also install safety signage at every door. The signage should be visible whether the door is opened or closed.

CO2 Safety Necessary Warning Signage

All our CO2 Safety Monitors come with the necessary safety signage. Shipping both English and Spanish versions you can also see the code or download copies of these signs to print here.

Note that the suggestions above are best practices gained from experience, but are not an endorsement of any specific location in your building. Every installation is different. If you have questions about your installation, contact your local building inspector.
