To put this in perspective, the Centers for Disease Control (CDC) notes that CO concentrations reach the Immediately Dangerous to Life and Health (IDLH) concentration of 1,200 parts per million (ppm) in only 7 minutes when a small 5 horsepower gasoline engine is run in a 10,000 cubic foot room.
Persons affected by CO display a lack of reasoning caused by reduced oxygen to the brain that can impair function and make them less likely to discern the danger in the environment.
Limiting Carbon Monoxide Exposure from Patrol Vehicles
While many risks of carbon monoxide (CO) exposure stem from mechanical issues, there are a series of best practices regarding limiting CO exposure that should be considered when operating a motor vehicle.
In general, police officers should avoid:
- Operating a vehicle with a defective exhaust system.
- Operating a vehicle with a defective emission system or poorly tuned engine.
- Driving a vehicle with the trunk lid or rear tailgate open.
- Driving a vehicle with holes in the car body.
- Warming up a vehicle in a garage, even with the outside garage door open.
- Operating vehicles in a garage, carwash, or any enclosed building.
Additionally, an exhaust hood must be sealed tightly and vented to outside, as well as being of sufficient capacity to remove all fumes.
Risks Specific to Defective Exhaust Systems and Vehicle Upfitting
Even a properly tuned gasoline engine will produce more than 30,000 parts per million (ppm) of carbon monoxide in the exhaust stream before the catalytic converter. Engines that are poorly maintained, have a poor design, or are defective can result in exhaust leaks.
- An exhaust leak can allow escape of carbon monoxide before it is converted to non-toxic CO2 in the catalytic converter.
- The carbon monoxide leaking from the exhaust system can enter the vehicle through holes in the body or open windows or doors.
NOTE: Many police departments outsource vehicle upfitting to a third party. If new holes created through the firewall to run wires for lights are not sealed properly, carbon monoxide can leak into the cab, putting officers at risk for CO exposure.
If you are experiencing issues with carbon monoxide stemming from your patrol vehicle, you should immediately contact your supervisor so the vehicle can be inspected, and if needed, repaired..
A service technician can inspect your vehicle to diagnose and correct any problems due to faulty parts, improper maintenance, or other issues.
