Carbon Monoxide Poisoning

Carbon monoxide (CO) is a poisonous, colorless, odorless and tasteless gas. Although it has no detectable odor, CO is often mixed with other gases that do have an odor. So, you can inhale carbon monoxide right along with gases that you can smell and not even know that CO is present. CO is a common industrial hazard resulting from the incomplete burning of material containing carbon such as ...

Kohlenstoffmonoxid – Wikipedia

Kohlenstoffmonoxid (fachsprachlich Kohlenstoffmonooxid, gebräuchlich Kohlenmonoxid) ist eine chemische Verbindung aus Kohlenstoff und Sauerstoff mit der Summenformel CO. Kohlenstoffmonoxid ist ein farb-, geruch- und geschmackloses sowie toxisches Gas. Es entsteht unter anderem bei der unvollständigen Verbrennung von kohlenstoffhaltigen Stoffen bei unzureichender Sauerstoffzufuhr.

1 Sources and Effects of Carbon Monoxide Emissions | The ...

CO may be a good indicator gas for other pollutants that are emitted at the same time but are not widely measured. The concentrations and spatial distributions of the copollutant species are generally not as well known as for CO. In particular, little data are available about exposure to air toxics present in the ambient environment. CO could be especially useful as an indicator of mobile ...

Carbon monoxide - Wikipedia

Carbon monoxide (chemical formula CO) is a colorless, odorless, tasteless, flammable gas that is slightly less dense than monoxide consists of one carbon atom and one oxygen atom. It is the simplest molecule of the oxocarbon family. In coordination complexes the carbon monoxide ligand is called carbonyl.. Thermal combustion is the most common source of carbon monoxide, however …

Introduction to Electrochemical (EC) Gas Sensors

2O → CO 2+ 2H+ +2e-Counter Electrode: ½O 2 + 2H+ + 2e-→ H 2O Overall: CO + ½O 2 → CO 2 Because the electrodes have a finite catalytic activity (which can change with time and temperature) it is necessary to limit the rate of diffusion of target gas into the sensor (using a barrier) to ensure the gas is efficiently reacted. This barrier takes the form of a small hole or capillary in the ...

CO and CO2 – What’s the difference? |

The molecular weight of CO is , where the molecular weight of CO2 is This means that the CO2 gas is much more dense than CO. CO2 will collect near floor level while CO will collect closer to the ceiling. OSHA lists danger levels for CO beginning at 35 ppm, and for CO2 starting at a 5,000 ppm time-weighted average.

How does a gas detector work? | Martek Marine

08/03/2019· Gas detectors use a sensor to measure the concentration of particular gases in the atmosphere. The sensor serves as a reference point and scale, producing a measurable electric current when a chemical reaction caused by a specific gas occurs. The sensor will monitor these currents and alarm the user when the presence of gas approaches an amount that is hazardous.
