Fixed vs. Handheld CO2 Detectors

portable co2 detector fixed co2 detector

Carbon Dioxide (CO2) is a unique, multifaceted gas that is absolutely critical in applications you love like dispensed soda or draught beer, as well as in some not so well know applications like waste water treatment, incubation, and even fire suppression.

However, while CO2 is extremely useful, the gas is hazardous and requires proper monitoring devices be installed or utilized by those who work around stored or produced Carbon Dioxide to eliminate potential injuries from occurring. 

Every day, CO2Meter receives dozens of customer inquiries in regards to CO2 safety devices.  One of the first questions our technical sales team tries to determine is whether a fixed CO2 detector or a portable CO2 detector is really best for the customers overall requirements, industry, and needs. 

It is always important to remember, that regardless of your environment or application, CO2 is an odorless, tasteless, and colorless gas that can only be detected by using devices that are designed to accurately measure the concentration of the gas. 

While some industry veterans will tell you they "feel a tingle" or "get an acidic taste in their mouth" when CO2 levels are elevated a typical employee, guest, or family member needs protection and proper monitoring to warn them of hazardous conditions.

According to The Occupational Safety Hazard Administration (OSHA), the initial alarm/warning for CO2 exposure is 5,000 ppm Time Weighted Average (essentially an average of all the readings over a rolling 8 hr. period).

CO2 concentrations higher than 5,000 ppm can lead to adverse health effects, injury and even death.

Standard industrial practices are for anyone handling CO2, whether it be in the form of dry ice, cylinders, or in bulk distribution to always be aware of proper CO2 safety precautions to prevent injury.  Every company has their own policies and procedures to help drive employee education, awareness, and performance.

There are two different types of gas detection monitoring devices available, fixed or wall mount CO2 detectors or portable/handheld CO2 detectors. 

Fixed/Wall Mount CO2 Detectors

CO2Meter offers Fixed/Wall Mount CO2 Detectors that are  designed to monitor and protect workers near stored or created carbon dioxide (CO2). Businesses that typically utilize fixed CO2 detectors include restaurants, beverage dispensing areas, cultivation facilities, industrial environments, and safety industries. What makes up a Fixed/Wall Mount CO2 Detector is that these devices are static, usually hard-wired and installed directly near the CO2 source. 

An accurate and reliable Fixed/Wall Mount CO2 Detector, like the CM-7000 CO2 Multi Sensor System will feature both audible and visual alarms, relays to trigger third party systems like a fire panel. alarm levels that conform to OSHA and fire code standards, and clearly mounted signage describing the potential hazard.

As a helpful reminder, CO2Meter recommends installing Fixed/Wall Mount CO2 Detectors sensing units at least 12 inches from floor level near the CO2 source and the display unit at eye level upon entry to the space. (i.e. For breweries a main CO2 source point would be the draught beer cooler. The sensing unit would be inside the keg cooler near the source itself at 12 in. from the floor, and the main display unit would be installed at eye level outside of the keg cooler to alert individuals prior to entering the room if local CO2 exposure limits are heightened.)

Portable/Handheld CO2 Detectors

In addition to Fixed/Wall Mount CO2 Detectors, CO2Meter also offers Portable/Handheld CO2 Detectors for those individuals who would work in and around hazardous areas and are looking for a portable, "on-the-go" detector.

Individuals who utilize Portable/Handheld CO2 Detectors typically stand by these devices due to their ability to alert individuals immediately upn entering an unsafe area. Applications that use Portable/Handheld CO2 Detectors include breweries, gas distribution, cultivation facilities, draft technicians, gas creation sites, and safety environments.

When you look at purchasing a Portable/Handheld CO2 Detector, the majority of these devices will provide the user with precise CO2 readings, audible/visual/vibrating alarms, a rugged design, data logging capabilities, protective IP54 housing and rechargeable Li-ion batteries for longterm use. 

It is important to always remember with Portable or Handheld CO2 Detectors that the user places these at their belt level as CO2 is heavier than air and will settle at the floor first, where keeping the device below head height is critical. 

Let's Discuss Applications

CO2Meter Restaurant and Food Applications     

Restaurants & Food

Any restaurant serving dispensed carbonated beverages is at risk. Every soda you drink or beer you pour contains a low percentage of beverage grade carbon dioxide that is mixed into the drink at specific levels.

While CO2 creates that sensational fizz all customers know and enjoy employees who work in and around the systems need to be protected. Many parts of the CO2 system can leak causing dangerous levels of CO2.

One area of potential hazard is the syrup pumps that drive the mixture of CO2, water, and syrup - these should be vented to the exterior of the building but often are not. Empty syrup bags or leaks in the pumps can drive CO2 levels above 5,000 ppm within a few moments!

In order to properly protect employees and customers facilities should install CO2 monitors that can be placed in an area that is most likely to experience a CO2 leak and ensure rapid detection to mitigate any hazards from occurring.

CO2Meter Breweries and Wineries Applications    

Breweries & Wineries

In the process of alcohol fermentation in brewing and wine making, large amounts of CO2 are generated.  A byproduct of years consuming sugar and turning it in to alcohol is CO2.

It is important to ensure that during purging or cleaning of tanks that precautions are taken to ensure employee safety. OSHA and Brewers Association offer proper procedures for confined space entry that should be followed as well as having "lockout - Tag-out" procedures in place.  Whether monitoring for spacial concentration rises or personal monitor CO2 mitigation is a primary concern for these employees and facilities.

Aside from the importance of fermentation and brite tank areas, another concern area in brewery applications are the walk-in draft coolers. Coolers are designed to be airtight to keep cold air in. However, the cooler can then trap CO2 leaks from loose tavern heads or splits hoses releasing deadly levels of CO2.

Without proper fixed/wall mount co2 detectors or portable handheld co2 detectors, an employee could easily be overcome by CO2 gas in the walk-in cooler, grain silo or mash tun areas. 

CO2Meter Agriculture Application 

Agriculture

In regards to agriculture applications, many inquiries stem from the use of Carbon Dioxide (CO2) in the grow rooms or cultivation facilities.  Studies have shown that facilities that enrich their growing environments with CO2 see a 20%-30% increase in plant yields.

These growers are essentially accelerating the photosynthetic process by utilizing CO2. However, like the walk-in draft coolers, these grow rooms are nearly airtight to ensure gas (and other elements) aren't wasted.

These confined spaces can trap the gas and create elevated concentrations that are hazardous.  Notifying occupants in the rooms and those about to enter the rooms of a hazard is critical to safety protocols. Fixed/Wall Mount CO2 Detectors should always be installed and in place to prevent potential injury from occurring in the grow space. 

 

 CO2Meter Fire Suppression Application 

Fire Suppression

When you think of CO2 and Fire Suppression you likely think of fire extinguishers. Your typical home or office fire extinguisher vaporizes CO2 under enormous pressure to create the "fog" you see.

That CO2 "fog" displaces the oxygen around the fire eliminating the source of the fire to "breath".

Large facilities with equipment that could be damaged by using a typical water sprinkler system also utilize CO2 as a fire suppressant but on a much larger scale. Dozens of CO2 cylinders under more than 300 psi are released to "flood" a space with CO2 and eliminate oxygen. 

These systems need to be maintained and tested for effectiveness regularly including providing full reporting and analysis to local fire officials for validation.

CO2Meter has designed and manufactures the only device that can help fire suppression testers meet the NFPA 12 standard.

In addition, CO2Meter also provides a Portable/Handheld CO2 Detector - Multi Gas Sampling Data Logger which is designed to simultaneously measure multiple gas concentrations through sampling methods and can be used in fire suppression testing and application. 

What Can You Do?

Ultimately, the first thing that you need to do to ensure your safety and the safety of others is to be notified of a leak before it gets out of hand, by proper detection from a CO2 Fixed Wall Mount, Desktop or Handheld Personal Safety Device.

Many industries decide to use both Fixed/Wall Mount CO2 Detectors, as well as Portable/Handheld CO2 detectors in order to ensure maximum prevention from CO2 exposure and ultimate safety precautions.

By ensuring your workers are properly educated and have the proper CO2 monitors available, you can mitigate any potential risks or hazards from occurring in your establishment.

Always remember, no matter where you work, live, or play, you should always be aware of the levels of atmospheric CO2 around you and understand the safety procedures to prevent injury from occurring.
