Bump Testing Gas Detectors Should Be Second Nature

Nov 17, 2020· A bump test is a simple process where you expose sensors in a gas detector to an expected concentration of gas that is greater than the alarm set points. If everything is working as expected, the gas detector will go into alarm. Bump testing is the only way to ensure that a gas detector's sensors and alarms are working.

Why is hydrogen such a big issue for CO sensors? | GfG ...

The reason that CO sensors are potentially susceptible to hydrogen (H2) interference is the reaction that is used to detect gas. Hydrogen is actually part of the detection reaction. The relative response to hydrogen depends on the brand and model of sensor. Some commonly used CO sensors show a relative response to hydrogen as high as 60%.

NFPA - Carbon monoxide alarms

Often called the invisible killer, carbon monoxide is an odorless, colorless gas created when fuels (such as gasoline, wood, coal, natural gas, propane, oil, and methane) burn incompletely. In the home, heating and cooking equipment that burn fuel are potential sources of carbon monoxide. Vehicles or generators running in an attached garage can also produce dangerous levels of carbon monoxide.
