Carbon Monoxide Poisoning Attorneys

Firepower for
serious
CO cases.

Carbon monoxide cases are rare, severe, and technically complex. Most injury lawyers will never handle a single one. At Cannon Law, we've litigated them many times — in multiple states — and we understand both the science and the law.

Why Cannon Law

We've handled CO cases most lawyers have never seen.

Unlike everyday car accidents, carbon monoxide cases are relatively rare — and severe. When injuries are this serious, you don't want an attorney learning on the job.

Deep CO Case Experience

We've litigated carbon monoxide cases in multiple states. That means we've already confronted the issues that arise in these cases — the medical disputes, the liability arguments, the technical evidence — and know how to handle them.

We Understand the Science

Our team understands CO pharmacokinetics — how the gas behaves in the body, how COHb levels are measured and interpreted, and how to reconstruct exposure timelines. That technical depth translates to stronger cases.

Trial-Ready from Day One

We build every case as if it's going to trial. That preparation is why defendants take our cases seriously — and why our CO settlements have reached seven figures.

You Choose the Strategy

It's your case. We'll give you our honest assessment of whether settlement or continued litigation is in your best interest, and then follow your lead. We're ready for either.

Where We Practice

Northern Colorado to coast to coast.

Carbon monoxide cases are not limited by geography. Our CO practice brings clients from across the country to work with a team that has the experience to handle these cases.

Primary

Colorado

Our home state. We're licensed in Colorado state courts and the U.S. District Court for the District of Colorado and the Tenth Circuit Court of Appeals. Fort Collins and Loveland are our home base, and we handle cases statewide.

Secondary

Wyoming

We have an active and ongoing Wyoming practice, licensed in state courts and the U.S. District Court for the District of Wyoming. Wyoming CO cases are handled with the same depth as our Colorado cases.

Nationwide

Other States

If you have a serious CO poisoning case in another state, contact us. We work with local counsel in other jurisdictions on cases where our technical expertise can make a difference. Good cases don't stop at state lines.

Types of Cases We Handle

Where CO poisoning happens.

Carbon monoxide poisoning can happen in many settings. Here are the situations we see most often.

🏠

Rental Homes

Landlords are legally required to provide safe, habitable housing — including working heating systems and CO detectors. When they defer maintenance to protect profits, tenants pay the price. We've litigated against large and small residential landlords.

🏨

Hotels & Vacation Rentals

Hotels face financial pressure to cut maintenance costs. Vacation rentals often lack formal maintenance programs entirely. Due to the size of hotel heating systems, CO can accumulate rapidly — and many hotels are not required to have detectors in every room.

🔧

Faulty HVAC Installation

Even in your own home, CO exposure can happen if a heating system is installed or maintained incorrectly by an unqualified technician. When a contractor's negligence causes injury, you may have a claim against them.

🏗️

Workplace Exposure

Generators, engines, and other equipment on job sites emit CO. When these are used in enclosed or poorly ventilated spaces, dangerous levels can build quickly. If workplace CO exposure injured you, you may have claims beyond workers' compensation.

🚗

Vehicle CO Exposure

Vehicle exhaust contains CO. Running a car in an enclosed garage — even briefly — can produce dangerous levels. Defective exhaust systems can also expose vehicle occupants to CO. We handle vehicle-related CO exposure claims.

🏊

Pool & Outdoor Equipment

Pool heaters and other large outdoor equipment can generate high concentrations of CO when they malfunction. Because these areas are typically unregulated for CO detection, exposure may not be identified until symptoms appear.

Our Technical Edge

We understand what the blood tests actually mean.

Carbon monoxide is a colorless, odorless gas. When you breathe it in, CO molecules bind to your hemoglobin — forming carboxyhemoglobin (COHb) — blocking your blood from carrying oxygen to your brain and organs.

The challenge in CO cases is that COHb levels drop rapidly once a person is removed from exposure and given oxygen. By the time blood is drawn in an emergency room, the level may not reflect peak exposure at all.

Our team understands the pharmacokinetics of CO — including how to back-extrapolate COHb levels to reconstruct what the exposure looked like at its worst. This technical knowledge matters when defendants argue that medical records don't show serious exposure.

We work with the right experts and know the questions to ask. That's the kind of depth that makes a difference in complex CO litigation.

COHb Level Reference

What Blood CO Levels Mean

1–3%
Normal (non-smoker)
10%
Headache, dizziness
20%
Throbbing headache, fatigue
30%
Confusion, severe symptoms
40–50%
Loss of consciousness
60%+
Fatal in many cases
Important: COHb levels fall rapidly after oxygen therapy. A "normal" reading at the ER does not mean there was no serious exposure. This is a critical issue in many CO cases — and one we know how to address.
Know the Signs

CO poisoning symptoms are easy to mistake for something else.

Carbon monoxide is invisible and odorless. Symptoms often resemble the flu or fatigue — and can come on gradually with lower-level, longer exposure.

Headache
Dizziness
Nausea or vomiting
Confusion
Shortness of breath
Blurred vision
Weakness or fatigue
Loss of consciousness

Longer-term or lower-level exposure can also cause memory problems, personality changes, and symptoms that persist long after the exposure ends.

If you experienced symptoms like these in a rental, hotel, vacation rental, or workplace — and those symptoms improved when you left — carbon monoxide may be the cause. Contact us for a free evaluation.

Our Track Record

Results we've delivered
for CO clients.

These are real cases we've handled. Every case is different, and we cannot promise a specific outcome in yours. But our track record shows we have the skills to take on complex CO cases and fight them to conclusion.

$2,000,000+
CO Poisoning — Rental Property

Pre-Cannon Law offer: $0. After nearly two years of litigation, two defendants agreed to pay policy limits totaling $2 million. A third claim was resolved separately.

$1,450,000
CO Poisoning — Rental Property

Pre-Cannon Law offer: $0. We litigated this case against four separate defendants and recovered $1.45 million for our client.

$400,000
Gas Poisoning — Apartment

Our client was poisoned in her apartment. Even though the gas wasn't CO, our experience with these cases was essential to ensuring she was compensated fairly.

Past results are not a guarantee of future outcomes. Every case is unique. Client may be responsible for costs in some circumstances. These results were obtained through settlement during litigation.

What to Expect

What happens when you contact us.

We keep things simple and transparent. Here's what the process looks like from your first call to resolution.

Free Case Evaluation

You talk to an attorney — not a paralegal or intake coordinator. We'll listen to what happened, ask questions, and give you an honest assessment of your situation. No pressure to hire us.

We Investigate

If we take your case, we move quickly to preserve evidence — maintenance records, inspection reports, detector logs, and building records. In CO cases, this evidence can disappear fast.

Build the Case

We work with medical and technical experts to document your injuries, understand the exposure timeline, and identify every responsible party. CO cases often involve multiple defendants.

You Choose the Strategy

We'll give you our honest recommendation: settle or litigate. Then we follow your decision. We're ready for either — including taking your case all the way through trial and appeal if that's what it takes.

Firepower when you need it.
