Carbon Monoxide Safety Tips for Businesses

August 2, 2026

Mammoth Takeaways

  • Carbon Monoxide Detection: Essential for detecting the invisible and odorless gas that poses severe health risks, including dizziness, nausea, and potentially fatal poisoning.
  • Common Sources in Businesses: Heating systems, gas-powered equipment, motor vehicles near buildings, and cooking appliances are significant sources of CO in commercial settings.
  • Prevention Measures: Installing CO detectors, regular maintenance of fuel-burning equipment, ensuring proper ventilation, and employee training are crucial steps in protecting against CO poisoning.

Imagine a silent, invisible threat lurking in your workplace—a gas that could put everyone at risk with no one knowing. That’s carbon monoxide.

So, why should you be concerned about it in your business? And why is a detector essential?

Below we’re going to cover the what’s, how’s, and why’s of carbon monoxide detection and safety.

What is Carbon Monoxide, and Why is it Dangerous?

Carbon monoxide is an invisible and odorless gas that is produced by the burning of carbon-based fuels. These fuels include wood, coal, propane and more.

Since this gas is odorless and colorless, it’s impossible to detect without the help of technology. But why is it important to know that there is carbon monoxide present in the air?

Carbon monoxide works by binding to blood cells and depriving the body of oxygen. Because of this, carbon monoxide (CO) can have severe negative effects on humans and animals. With long enough exposure and high enough concentrations, carbon monoxide poisoning can be fatal. It has garnered the name “silent killer” due to the fact that the odorless gas has taken lives while people sleep unaware.

Negative effects can manifest in the form of dizziness, confusion, nausea, and cognitive impairment. If you or anyone is experiencing these symptoms, be sure to check that your carbon monoxide detector is working, or have your area checked by a professional for your safety.

Sources of Carbon Monoxide in Businesses

Since the only way to detect this potentially lethal gas is by using technology, it’s important to have your business properly equipped. Several sources of carbon monoxide may exist in your business.

Common CO Sources in a Business

Heating Systems

Especially if you’re located in cold climate areas, you likely have a heating system somewhere in your building. Many heating systems function by burning oil or gas to produce heat. The heat is transported through vents to raise the building’s temperature.

When the equipment works as intended, there should be no carbon monoxide or byproduct escaping the machine during operation. If there’s a leak or machine damage, CO could enter the room or, even worse, the ventilation system.

It’s important to note that other heating devices, such as gas space heaters, also produce this deadly gas and should never be used indoors without proper ventilation. Always air on the side of caution when it comes to safely heating your business.

There are electric heating devices available for purchase and installation, and these units do not create carbon monoxide. One drawback is the additional pull on electricity and the increased cost.

Gas-powered Equipment

Some industries use gas powered equipment such as forklifts, generators, lawn mowers, or similar machines. The engines of these devices create CO, and if the system is malfunctioning, it can add unsafe levels to the environment. In a contained space like a building, this gas can build and create a health hazard.

Any motorized equipment should be routinely inspected for faults to reduce the chance of contamination.

Motor Vehicles In or Near the Building

Idling cars, trucks, and delivery vehicles near entryways, docks, and windows can also be a cause for concern. Non-electric cars produce a lot of exhaust when operating and if that exhaust is drawn into an enclosed space, it can build and become a problem. Keep cars away from openings and vents, and install adequate ventilation in the building.

Industrial Equipment

Iindustries can sometimes employ large kilns, ovens, stoves, and other carbon-burning appliances in their manufacturing process. It’s extremely important to regularly check and maintain this equipment for the safety of those in the building.

Water Heater

Like the heating systems mentioned earlier, water heaters pose a similar risk for the same reasons. Malfunctioning equipment can cause inefficient burning and produce an excess of carbon monoxide.

Cooking Appliances

In kitchens and cooking areas, ovens and grills may be gas-powered. These appliances can spring leaks, which is an extreme hazard due not only to carbon monoxide but also because of exposure to the use of open flames as well. Gasses used in culinary applications and, in fact, most applications contain an additive (mercaptan) that has the scent of rotten eggs. If you smell this chemical in any kitchen area, it’s possible that there is a gas leak from the stove or other appliance.

Risks of Carbon Monoxide Poisoning for Businesses

Carbon monoxide poisoning can lead to serious health consequences for employees and visitors, including headaches, dizziness, confusion, unconsciousness, and, in severe cases, death. For businesses, CO incidents can cause operational disruptions, legal liabilities, and damage to reputation. Nobody benefits from being hurt by carbon monoxide.

Importance of Preventing Carbon Monoxide Poisoning in the Workplace

Preventing CO poisoning is necessary to protect the health and safety of employees and clients. It also helps businesses avoid potential legal issues and maintain a safe working environment, which can enhance productivity and morale. It’s important to protect all of your assets.

Actions to Take When a Carbon Monoxide Alarm Goes Off

In the event of a carbon monoxide alarm being triggered, specific measures should be taken. It’s important to follow these steps to ensure the safety and well-being of your employees and patrons:

  1. Evacuate Immediately: Get everyone out of the building and away from the threat. Prolonged exposure can do more damage.
  2. Call Emergency Services: Contact 911 or your local emergency number. Inform them of your concerns about a gas leak at your location.
  3. Do Not Re-enter: Stay outside until emergency responders declare the building safe. Professionals will have proper tools to test for carbon monoxide.
  4. Seek Medical Attention: Anyone showing symptoms of CO poisoning should get medical help immediately.
  5. Repair Any Malfunctions or Faulty Equipment: If the source of the leak is found to be a malfunctioning system or improper ventilation, it is imperative that the problem is fixed immediately before allowing people into the building.

Recognizing the Symptoms of Carbon Monoxide Poisoning

Although briefly mentioned, it’s important to become acquainted with the symptoms of carbon monoxide poisoning. If you, your employees, or customers are experiencing any or many of these symptoms, it’s critical to call licensed professionals and check for carbon monoxide hazards.

Common Symptoms:

  • Headache
  • Dizziness
  • Weakness
  • Nausea or vomiting
  • Shortness of breath
  • Confusion
  • Loss of consciousness

Although other conditions or events could cause these symptoms, it’s a good idea to first check for CO with an abundance of caution.

Protecting the Workplace and Employees from Carbon Monoxide Poisoning

  • Install CO Detectors: Place detectors in key areas such as near fuel-burning appliances and in common areas. Devices should be placed where alarms are easily audible.
  • Regular Maintenance: Ensure all fuel-burning equipment is regularly serviced and maintained.
  • Ventilation: Keep areas well-ventilated to prevent CO buildup.
  • Employee Training: Educate employees about CO risks and emergency procedures.

Installing and Maintaining Carbon Monoxide Detectors in the Workplace

For the best carbon monoxide (CO) safety in commercial places, it’s important to follow some key steps. First, pick detectors made for commercial use and make sure they are reliable. Proper placement is important, so put detectors near places where CO might come from and in common areas to cover the most space.

Test the detectors every month to make sure they are working properly. Also, change the batteries when needed, usually every six months, to keep them working without downtime. Lastly, get a professional to inspect the entire system once a year to make sure everything is in top shape.
