Vehicles

Most of us are exposed to carbon monoxide (CO) from gas-powered vehicles every day. We tend to hear about this type of exposure mostly in relation to outdoor air pollution. However, there are a number of ways CO can quickly progress from being a low level environmental concern to being an immediate threat to life. CO is an invisible, odorless and non-irritating gas that is present at extremely high levels in car exhaust and can kill within minutes. CO can poison the air both inside and outside of a vehicle, and even the air in a home (drivers of keyless ignition vehicles should be especially aware of this danger). Most vehicles do not come equipped with CO detection, which means there are no warnings when CO reaches dangerous levels and the engine will not shut off on its own. Here are some important things to know and ways to stay safe.

BE IDLE AWARE

Be aware inside your car:

Be aware outside your car:

 

KEYLESS IGNITION VEHICLES

Keyless vehicles pose a particular danger with regard to CO.  Most of these vehicles were manufactured without critical safeguards in place to protect people from scenarios in which the vehicle can inadvertently be left running or inadvertently be switched on while in an attached garage.  If this happens, deadly levels of CO from the car’s exhaust can fill a home.  Although car exhaust has an odor, CO does not – it is undetectable without the aid of a CO alarm (recommended to be on every level of a home and near all sleeping areas) .  Many people have been injured or killed in this way.  Exposure to high levels of CO can quickly result in incapacitation and/or unconsciousness preventing escape to fresh air.

What can you to do to stay safe?

  • Install CO alarms in your home
  • Understand how your keyless ignition works (see video below) and be alert to the limitations of your vehicle’s ability to safeguard you
