As the weather cools, and people begin turning up the heat indoors, it’s important to be aware of the dangers of carbon monoxide, especially if you live in an apartment building. In places like New York City, it’s no surprise that the majority of people rent. According to the Wall Street Journal, 64 percent of the NYC population rented as of 2013.

According to the National Conference of State Legislators, over 10,000 people suffer carbon monoxide poisoning every year, and carbon monoxide poisoning kills more than 500 people annually.

Like most states, New York has strict rules regarding ventilation and carbon monoxide detectors. The New York City code requires carbon monoxide detectors in all new and existing one- and two-family homes, hotels, apartment buildings, nursing home, schools, and dormitories. Furthermore, there must be a carbon monoxide detector within 15 feet of the main entrance to every sleeping room. In 2014, New York State lawmakers passed a bill that also requires all restaurants and commercial buildings in the state to install carbon monoxide detectors.

Known as Steve Nelson’s law, the bill was proposed in memory of a Long Island restaurant worker who died when he was exposed to toxic levels of carbon monoxide due to a defective water heater flue pipe in the restaurant’s basement. The carbon monoxide levels were so high, even some of the emergency personnel who responded to the scene became ill. Under the new law, every commercial building and restaurant in New York must install carbon monoxide detectors by June 2015.

Why Carbon Monoxide Is So Dangerous

Because carbon monoxide is colorless, tasteless, and odorless, it is often called the “silent killer.” The gas is produced any time you burn fuel in small appliances, such as generators, gas grills, fireplaces, gas stoves, and furnaces. Carbon monoxide is also produced in the exhaust of vehicles. Too much of the gas can lead to serious health problems and even death.

The symptoms of carbon monoxide poisoning include headache, dizziness, nausea, vomiting, chest pain, confusion, and vomiting. Carbon monoxide can also cause a person to feel drowsy and eventually fall asleep, which is why it is so dangerous to leave a vehicle running in a garage or other enclosed space.

Many new homes and apartment buildings have a carbon monoxide detection system integrated into the smoke alarm system. If your home or apartment does not have a carbon monoxide detector, you can purchase one (or several, depending on the size of your home) at a variety of stores for under $20. It’s a small investment for something that could very well save your life.

Introduction

Carbon monoxide poisoning is the second most common cause of non-medicinal poisonings death. According to the CDC, over 10,000 are poisoned by carbon monoxide needing medical treatment each year and more than 438 people in the U.S. die annually from carbon monoxide poisoning.

>With the number of illnesses and death caused by high levels of carbon monoxide (CO) in homes and buildings, state legislatures have begun adopting laws mandating the use of carbon monoxide detectors. The mandate varies from every enclosed room being required to have detectors, to every room that has a smoke alarm to have a detector, with only day-care centers and group homes needing detectors.

As of March 2018, a majority of states have enacted statutes regarding carbon monoxide (CO) detectors, and another 11 have promulgated regulations on CO detectors. Alaska requires detectors approved by the state fire marshal be installed in all dwellings. Connecticut requires them in all new construction, as does New Hampshire, Oregon, Pennsylvania, Rhode Island, Utah, Vermont, Washington and West Virginia. Florida also requires them in new construction, and in every room with a boiler. Minnesota passed a law requiring detectors in motor boats.

CO Detectors in Homes

27 states and the District of Columbia require carbon monoxide detectors in private dwellings via state statute: Alaska, California, Colorado, Connecticut, District of Columbia, Florida, Georgia (via adoption of the International Residential Code), Illinois, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Nebraska, New Hampshire, New Jersey, New York, North Carolina, Oregon, Pennsylvania, Rhode Island, Tennessee, Utah, Vermont, Washington, West Virginia and Wisconsin. Certain states limit the installation to buildings with fossil-fuel burning devices, others only require the device be installed upon the sale of the property or unit.
Another 11 states require carbon monoxide detectors in private dwellings regulatorily through the adoption of the International Residential Code or via an amendment to their state’s building code: Alabama, Georgia, Idaho, Kentucky, Louisiana, New Mexico, North Dakota, Oklahoma, South Carolina, Virginia, and Wyoming.

CO Detectors in Schools

California, Connecticut, Illinois, Maine and Maryland require carbon monoxide (CO) detectors in school buildings.

CO Detectors in Hotels and Motels

Fourteen states require the installation of carbon monoxide detectors in hotels and motels under the statute.
Three of those states (New Jersey, Vermont and Wisconsin) have complementary administrative regulations.
Two states (Kansas and Washington) have requirements through administrative regulations alone.
