Parents deserve to know whether their children are being exposed to carbon monoxide.

Pregnant mothers deserve to know their unborn babies are protected.

Older adults deserve protection from an invisible gas that can make health problems worse and cause serious harm — or even death.

Please sign this petition to help update carbon monoxide alarm standards and protect children, pregnant women, older adults, pets, and people with health conditions.

Every year, families across America trust carbon monoxide (CO) alarms to protect them from an invisible, odorless, deadly gas.

Most families believe that if their CO alarm is silent, their home is safe.

But CO alarms operate under UL 2034, a voluntary standard that limits what manufacturers can make alarms do.

UL 2034 was developed more than 30 years ago using research from the 1960s that did not fully consider how CO exposure affects children, unborn babies, older adults, pets, and people with health conditions.

Under UL 2034, CO alarms:

• Cannot show or alert you to CO levels below 30 parts per million (ppm).
• Are required to stay silent for hours after CO exposure begins.
• Are required to sound only after CO levels stay above 70 ppm for up to 4 hours.

That means families can be breathing CO while their alarm shows nothing and never sounds a warning.

 

 

And this is not just a home safety issue. CO exposure can happen in schools, daycares, hotels, offices, restaurants, gyms, and other public buildings families visit every day.

Families deserve earlier warning — and that is why we are asking for your signature.

New Research Raises Serious Concerns

In January 2026, the Fire Protection Research Foundation published a major review of CO alarm standards, exposure, and health effects.

The review found that children, pregnant women, unborn babies, older adults, and people with health conditions are especially at risk from CO exposure.

The report explains that:

• Children can absorb CO faster than adults.
• CO crosses the placenta, and the fetus can absorb twice as much CO as the pregnant mother.
• CO can harm the brain, heart, and developing body even when exposure is not recognized right away.

Americans Are About To See This Problem FirsthandIn July 2026, Good Morning America will spotlight this issue nationally with a demonstration showing how CO alarms function when exposed to CO inside a controlled test chamber.

Viewers will see something many Americans do not realize: a home can contain CO even when the alarm on the wall remains silent.

The technology to detect and show lower levels of CO already exists today.

We Are Calling For Common-Sense Updates

Safety leaders and standards partners are already in a position to help move this issue forward.

We respectfully urge them to work together with urgency to speed up the following updates to CO alarm standards:

• Earlier warning for CO exposure
• More accurate digital CO displays
• Better protection for children, pregnant women, older adults, pets, and people with health conditions
• Alerts and instructions that are easier to understand
• Current CO alarms save lives, and every home should have working CO alarms today.

But families deserve modern protection and standards that keep up with science and technology.

Please sign this petition to help update CO alarm standards and protect families nationwide.

Because when it comes to an invisible poisonous gas, earlier detection can save lives.
