The Dangers of CO2 for Restaurant and Bar Employees

In order to make carbonated beverages carbonated, CO2 must be infused into the liquid. Carbonated beverage machines are installed in just about every restaurant and bar across America. Most customers don't think anything about them; they are everywhere. But for restaurant and bar managers and employees, the dangers and risks associated with working closely with carbonated beverage machines are a reality.

Carbon dioxide (CO2) is a gas that is toxic to humans in concentrations as low as 0.5%, and a leak in one of these carbonated beverage systems exposes those nearby to toxic fumes. Carbon dioxide is odorless and colorless and can go undetected until adverse effects begin taking place. Leaks can occur due to improper installation, a faulty system, and simple user error. In order to be sure that leaks of CO2 do not go undetected, it is important and often mandated by OSHA for all restaurant and bar establishments to have a CO2 detector. Without awareness of a leak, employees are at risk of succumbing to CO2 poisoning, which induces symptoms like headaches, deeper breathing, and increased heart rates. If the person is not removed from the area with a high concentration of CO2, symptoms will reach the point of unconsciousness and then death, all of which are caused by the simple inhalation of CO2.

Physiological Effect of CO2 Inhalation

Because CO2 is colorless and odorless, symptoms of inhalation can occur for seemingly no reason. The effects of CO2 inhalation may at first be attributed to something else and the victim may have no idea of the seriousness of the issue. When a person begins to inhale CO2 instead of oxygen, rapid breathing and headaches can begin to occur. The body will try to breathe faster so that it can take in more oxygen when it realizes it is being deprived of oxygen. But, that will cause the person to inhale even more CO2, which can cause headaches due to low oxygen levels. If the brain is deprived of oxygen for long enough, the body will pass out to cease all other functions besides focusing on breathing. At this point, the person is unable to move away from the CO2 source and someone else needs to remove them to prevent death. If the person is completely starved of oxygen, they will die of asphyxiation.

Are Your Workplaces Safe?

These are very real dangers that employees of restaurants and bars can potentially be exposed to while at work. But, there are ways to ensure your workplace is a safe place to be. One of the main ways to do this is by installing CO2 monitors. CO2 monitors work like smoke detectors. We keep smoke detectors and carbon monoxide (CO) detectors in our homes because these gases are dangerous to us, and we want to be warned of their presence before it is too late. Similarly, restaurants and bars should have CO2 detectors/monitors because that is the gas most likely to cause problems. Without any sort of CO2 monitor or detector in an establishment where carbonated beverage machines are used, the employees could be at risk.

Analox CO2 Safety Monitors Overview

Whether you need to install a CO2 monitor for the first time or you are looking for an upgrade to your current model, the Analox CO2 safety monitors are the place to start your search. Analox models are the industry leaders when it comes to any type of CO2 monitor. They have been tried and tested in all situations to be sure they are accurate and offer enough warning time for employees to rectify the situation and/or retreat from the contaminated area before any harm is done. Analox CO2 safety monitors are highly versatile and customizable, as well. They can be used to create and build a system of monitors or can be used standalone. Standards around the world, including National Boiler Inspection Code (NBIC), OSHA, NFPA55, and IFC, mandate that employees and members of the public are not exposed to potentially dangerous levels of CO2 as it's a highly toxic gas in relatively small quantities.

Popular Products

  • Analox A50 - This model of CO2 monitor is a wall mounted monitor best suited for a single point of monitoring that should be mounted near the location where a potential CO2 leak could occur. Should high levels of CO2 be detected, an audible and visual alarm will go off to warn employees and customers. For instances where an audible alarm may be difficult to hear, flashing LED lights will also warn anyone near the contaminated area of high levels of CO2. In addition to the standard model, the Analox A50 is also available in a dual monitor for both CO2 and nitrogen. If your building is at risk of a nitrogen leak as well, this detector is the perfect all in one. This monitor is ideal for places where these gases are stored or piped. Most commonly, this monitor is found in fast food restaurants, cafes, cider barns, breweries, craft breweries, wineries, kitchens, nuclear power plants, night clubs, swimming pools, sports stadiums, and spas and leisure centers. Besides keeping employees and customers safe, the monitor is in compliance with regulations from EH40, OSHA, NBIC, NFPA55, IFC and TUV that require employees and customers not be exposed to potentially dangerous levels of CO2.
  • Analox Ax60 - The Analox Ax60 is one of their most widely used products. It can be found in McDonald's restaurants across the world, to give you an idea of its widespread use. The unit is wall mountable and designed specifically for the beverage and hospitality industries, which require CO2 monitoring in multiple site locations. It is ideal for fast food restaurants and pub cellars. The Analox Ax60 comes with a central display unit and can be connected with multiple sensors and monitors. Sensors can and should be placed in high impact areas where CO2 accumulation is most likely to occur. They should be placed at low levels near the floor since CO2 is heavier than air. If high levels of CO2 are detected, a warning, both audible and visual, will go off to warn employees and customers alike. An alarm will sound but, for noisy areas, a flashing LED will also go off to ensure everyone in the vicinity is aware of the threat. Besides keeping employees and customers safe, the monitor is in compliance with regulations from EH40, NBIC, OSHA, NFPA55, IFC and TUV that require employees and customers not be exposed to potentially dangerous levels of CO2.
  • Aspida - The Aspida CO2 monitor is a portable detector that can be used wherever needed throughout the building. It is designed to be a personal CO2 detector that can be worn on the body, but it also has the ability to be wall mounted as a backup CO2 monitor when one is needed. The unit is compact yet robust and able to detect CO2 with accurate precision. The Aspida is equipped with an audio/visual warning system to alert the user of high levels of CO2 in the area. It is available as a sole CO2 monitor, but like the Analox A50, can also be purchased as a dual monitor for both CO2 and nitrogen. The Aspida is both affordable and easy to use, making it one of the most popular CO2 monitors for employees on the go. It is best suited for beverage gas delivery drivers and technicians to ensure they are not exposed to high levels of CO2 while in their trucks or during the transfer of the units from the truck to the final destination. Besides keeping employees and customers safe, the monitor is in compliance with regulations from EH40, NBIC, OSHA, NFPA55, IFC and TUV that require employees and customers not be exposed to potentially dangerous levels of CO2.

    Although the Analox A50 is rated IP65, NEMA 4 and is splash proof, in some areas, especially if high pressure hosing is used, water can be forced in to the CO2 sensor resulting in damage and false alarms. To protect against this, we recommend fitting a splash guard, the use of this water deflector does not affect the response time of the Analox A50.
