Title: Carbon Monoxide
Description: It is very important when running a vehicle in the street rod shop to take necessary safety precautions regarding carbon monoxide. Carbon monoxide is found in gasoline engine exhaust. It displaces oxygen in the bloodstream, which results in carbon monoxide poisoning.
The concentration of carbon monoxide in the air is measured in parts per million (ppm). This means that in one million parts of air, a certain number of the parts are carbon monoxide. The chart to the left shows how a person is affected when exposed to different levels (ppm) of carbon monoxide. The horizontal axis shows the duration of exposure in hours. The vertical axis shows the type of health effects that exposure to carbon monoxide can have on a person’s health. Each curve represents a different concentration of carbon monoxide. For example, if a person is exposed to a concentration of 100 ppm carbon monoxide for less than 1 hour, no symptoms are noticeable. If the time of exposure at this concentration is increased to 10 hours, the person will experience headaches and reduced mental ability. Also note that if the concentration level are much higher, say 300 ppm, vomiting, comas, and death can occur in a much shorter period of time.
Based on this information, it is critical that when running an engine in the shop, the exhaust of the engine should be ventilated to the outside so that there is no chance of carbon monoxide exposure.
Note that carbon monoxide is easy to detect in the shop. There are various low cost monitors that read the amount of carbon monoxide (ppm) in the air. Many also have audible alarms that sound when the danger level is reached.

The carbon monoxide alarm in the photo to the left, shows the carbon monoxide concentration in ppm and plugs directly into a 110 volt wall outlet.
