Carbon Monoxide (CO) - A Danger Invisible to the Human Senses

Matt Shaw

Gas Chemical Details

Carbon Monoxide is a colourless, odourless gas, to the human senses it is completely invisible. Carbon Monoxide is a highly toxic gas.  It is termed a toxic (blood) asphyxiant, meaning it reduces the oxygen transport properties of the blood.  Low ppm doses of Carbon Monoxide can cause headaches and dizziness, if the victim is removed to fresh air no permanent damage will result. High concentrations however, can saturate a person's blood in a matter of minutes and quickly lead to respiratory arrest or death.

Carbon Dioxide (CO2) - A Greater Hazard Than Often Considered

Matt Shaw

Gas Chemical Details

Despite the fact Carbon Dioxide is naturally present in the atmosphere (about 400ppm) and we exhale it when breathing, CO2 is one of the most frequently overlooked toxic gases. Both colourless and odourless, CO2 in high concentrations poses an extremely dangerous hazard.

Oxygen (O2): All you need to know about the gas you need to live

Matt Shaw

Gas Chemical Details

Oxygen, the most abundant element in the earth’s crust is of great interest due to the fact that it’s essential in the respiratory processes of most living cells. It is found in both the air we breathe and the water we drink.

Chlorine Gas Calibration - Challenges for Gas Detection Instruments

Greg Shires

The process of gas calibration involves the testing and comparison of a gas detection device against some fixed reference value. The process includes using an accurate gas mixture as a reference and comparing it with the values provided by the instrument being tested. The cylinder mixture or device that produces the assigned correct value is known as the standard and it plays a vital role in all gas calibration.
