When Can You Take Legal Action Against a Business for Carbon Monoxide Poisoning?

Randy Rozek • June 27, 2025

Carbon monoxide poisoning is a serious and potentially fatal condition caused by exposure to high levels of carbon monoxide gas, an odorless, colorless substance produced by burning fuel. This gas can accumulate in enclosed spaces, posing a severe risk to individuals who inhale it. When businesses fail to maintain safe environments and customers or employees suffer from carbon monoxide poisoning as a result, victims may have legal grounds to take action. Here's when and how you might be able to sue a business for carbon monoxide poisoning.


Understanding Carbon Monoxide Poisoning


Carbon monoxide is produced by combustion engines, heaters, furnaces, fireplaces, and other fuel-burning appliances. When these appliances are improperly installed, poorly maintained, or inadequately ventilated, CO can build up and lead to poisoning. Symptoms of CO poisoning include headaches, dizziness, nausea, confusion, loss of consciousness, and in severe cases, death.


In many commercial settings such as hotels, restaurants, offices, rental properties, and factories, business owners are legally obligated to ensure their premises are safe. That includes proper maintenance of appliances, regular inspections, and the installation of carbon monoxide detectors in accordance with local laws.


Legal Grounds for a Carbon Monoxide Lawsuit


There are several legal theories under which a victim of carbon monoxide poisoning can take action against a business:


1. Negligence


To sue for negligence, the victim must prove four elements:


  • Duty of care: The business had a legal responsibility to maintain a safe environment.

  • Breach of duty: The business failed to uphold this duty (e.g., not servicing a furnace or installing CO detectors).

  • Causation: The business's breach caused the CO poisoning.

  • Damages: The victim suffered harm, such as medical expenses, lost wages, or pain and suffering.

For example, if a hotel failed to detect a faulty heater that emitted CO, and guests became sick, the hotel could be found negligent.


2. Premises Liability


This legal principle holds property owners and occupiers responsible for accidents and injuries that occur on their property due to unsafe conditions. If a business knew or should have known about a CO risk and did nothing to address it, they could be held liable under premises liability laws.


3. Product Liability


If the poisoning was due to a defective appliance or detector, victims may have a claim against the manufacturer or installer. This type of lawsuit could be based on design defects, manufacturing defects, or failure to warn users about potential dangers.


Who Can Be Held Responsible?


Depending on the circumstances, multiple parties may share liability:


  • Business owners or operators

  • Landlords or property managers

  • Maintenance or HVAC contractors

  • Manufacturers or distributors of faulty equipment


An attorney can help determine which parties are potentially liable based on the facts of the case.


What Compensation Can Victims Receive?


Victims of carbon monoxide poisoning may be entitled to compensation for:


  • Medical expenses (immediate and long-term)

  • Lost income or diminished earning capacity

  • Pain and suffering

  • Emotional distress

  • Permanent disability

  • Wrongful death (if a family member dies from CO poisoning)


When to Contact a Lawyer


If you or a loved one has suffered from carbon monoxide poisoning and suspect a business is at fault, consult a personal injury attorney as soon as possible. Carbon monoxide cases can be complex, requiring expert witnesses, medical evidence, and proof of negligence or misconduct. Early legal action ensures vital evidence is preserved and deadlines for filing a lawsuit (statutes of limitations) are met.
