Portable carbon dioxide (CO2) safety monitors are useful tools in breweries, restaurants or any business that uses tanks or cylinders of stored CO2. While this gas is a necessity, it can also be hazardous to employees or customers if not treated carefully.
After consulting with various partners, customers, and industry professionals in the field, we chose the top 5 portable CO2 safety monitors that are deemed the "best" in the industry. We looked at critical features such as safety indicators, ease of use, durability, battery life, customization, and of course cost.
Why use a Portable CO2 Safety Monitor?
The main importance when it comes to CO2 safety is that carbon dioxide is colorless, odorless, and tasteless. Unless you have a safety monitor installed or on hand, you may never know the gas is present until its too late.
Many incident reviews and case studies have shown the severe health effects of CO2 exposure including the following:
- Inhalation - Inhaling high concentrations of CO2 can affect respiratory functions as CO2 displaces oxygen in the air. High levels of CO2 can cause nausea, vomiting, convulsions, fatigue, loss of consciousness and even death. These symptoms can occur almost instantaneously.
- Skin/Eye Contact - Due to its low temperature in a liquid state, direct contact of liquid CO2 with the human body dangerous. It can cause irritation and damage. Wearing proper PPE including eye protection is required when working with liquid CO2.
While working in and around CO2 gases in the brewery, many industry leaders rely on Personal CO2 Safety Monitors to ensure safety and accurately monitor gas levels on the go.
CO2 Safety in the Workplace
It is always important to be aware of what effects CO2 can have on an individual's health. How can an employee ensure they are safe and their establishment protected?
As a brewer or industry worker, you occasionally can spend time cleaning, servicing, or performing maintenance inside fermenters, grain silos, bib racks, mash tuns, kettles, draft coolers, and more.
When working in and around these areas it is important to follow specified safety protocols, always wear appropriate protective equipment, ensure CO2 safety monitors are in place, and educate those around you on the proper safety precautions.
