Bump Testing your Gas Detectors
This video discusses the importance of bump testing your gas detectors prior to use.

August 2015 Newsletter: Carbon Monoxide - Be Alarmed!
Cooler weather means furnaces are turned on, plant doors shut and a rise in carbon monoxide poisonings. Carbon monoxide (CO) is a colorless, tasteless and odorless gas this is virtually impossible to detect by the human senses. It is produced by incomplete combustion processes such furnaces, small gasoline powered engines and poorly tuned forklift propane and gasoline engines or from forest and structure fires. The toxic effects of low levels of CO include headaches, dizziness and nausea. At high levels (500 ppm and up), confusion, cyanosis, angina and asphyxiation can occur. In the lungs the CO molecules take the place of oxygen molecules and bind themselves to red blood cells (hemoglobin). This binding is very strong and does not allow oxygen molecules to attach, thus oxygen cannot be sent into the body. Asphyxiation quickly takes place.
