Why it matters
Most carbon monoxide poisonings are never diagnosed. They look like flu, a migraine, a bad week. By the time someone connects the headaches to the furnace, the evidence has often been repaired, aired out or thrown away.
Colorless. Odorless.
No warning a person can sense. A detector is the only way to know, and many homes and hotel rooms still don’t have one.
Damage that arrives late
Memory loss, poor concentration and mood changes can appear weeks after exposure, long after the leak is fixed.
Cases won on detail
Blood tests, alarm records, fire reports and inspections decide outcomes. Knowing what to keep, early, changes everything.
The instrument
A silent alarm is not a safe home.
Carbon monoxide is measured in parts per million. Alarms certified to UL 2034 sound only after exposure at these levels for a set time, so harmful long-term exposure can go on for months without a sound.

News & insights
The news, with expert context.
“Is this a safe distance?” A generator photo sparks urgent warnings
After several days without electricity, one homeowner asked online whether their portable generator was far enough from the house.
Rob’s view — at least 20 feet from the house, never in a garage, exhaust pointing away from doors and windows. Make sure the generator is serviceable, and if it is rented, make sure it has a safety tag.
How often should you test, replace and maintain a carbon monoxide detector?
Rob’s view — test monthly, and replace on the date printed on the alarm. If there is no date printed on the alarm, write the date on it with a permanent marker. The alarm will last the life of its battery: when it starts beeping (between 5 and 7 years), it’s time to replace it. CO alarms are not expensive, but will potentially save your life for the cost of just a few cents a month.
Five treated for carbon monoxide poisoning at a DC parking garage
Rob’s view — enclosed garages need working ventilation and CO monitoring, not just open doors.
By state
A carbon monoxide lawyer in every state.
Detector requirements, landlord duties and time limits differ by state. Choose yours to start a review with it filled in.
No state matches that search.
Do I have a carbon monoxide poisoning case?
You may, if someone else was responsible for the source — a landlord, hotel, employer or manufacturer — and you were harmed. The free review helps you find out in about five minutes.
How can carbon monoxide poisoning be proved?
Medical records, a carboxyhemoglobin blood test, alarm readings, fire department or utility reports and inspection findings all help. We explain what to collect and keep.
My symptoms started weeks later. Can I still claim?
Delayed effects on memory, concentration and mood are well documented. A late diagnosis does not rule out a claim.
How long do I have?
Time limits depend on your state and the type of case, and some are short. Start the review as soon as you can so the deadline can be checked.
What does it cost?
Nothing. The review is free and confidential, with no obligation to go ahead.
