Carbon Dioxide (CO2)
Carbon Dioxide (CO2)
Carbon Dioxide is a colourless, odourless gas which is a natural component of the air we breathe, yet is toxic in higher concentrations. It is heavier than air.
Increased levels of Carbon Dioxide results in progressive physiological effects (see below) resulting in life threatening situations in high concentrations. It can also deplete the Oxygen content of air, resulting in a risk of asphyxiation. Carbon Dioxide in its dry form is commonly called ‘Dry Ice’

Safety Gas Detection manufactures Carbon Dioxide detection systems which detect the presence of low levels of Carbon Dioxide, and give a Carbon Dioxide Alarm.
