6. Gas Types
IMPORTANT
REMEMBER SAFETY FIRST
Carbon Dioxide (CO2)
The purpose of CO2 is to provide a blanket of gas on the surface of the beer in the keg at a slightly
higher pressure than the equilibrium pressure. This prevents the CO2 percentage in the beer from
changing, which would alter the taste and appearance of the beer from that intended by the brewer.
Mixed Gases (CO2/N2)
These gases are a mixture of Carbon Dioxide and Nitrogen (N2) in varying proportions. They should be
used on high pressure systems to help prevent over carbonation. Stout mix is a 70%N2/30%CO2 mix
required to dispense Nitrogenised Beverages.
Cylinder Pressure
The pressure in a cylinder of C02 is approximately 5-6,000kPa (800psi)
The pressure in a cylinder of mixed gas approximately 12-13,000kPa (1700psi).
CAUTION
Always employ safe working procedures when handling Gas
and Gas Equipment.
7. AS5034 CO2 Safety Equipment
All cool rooms that have a CO2 system in them require a CO2 monitor and alarm. Our “Site Risk Assessment”
(Appendix D) will have highlighted and addressed any issues.
Carbon Dioxide (CO2)
DANGER
CO2 in a confined space can be lethal. In high enough
concentrations it can paralyse the respiratory centre, which
could result in death. Some symptoms of CO2 exposure can
be shortness of Breath, rapid heartbeat, nausea, and
dizziness.
Properties
NOTE
CO2 is a colourless, odourless and tasteless gas. It is non-
combustible and heavier than air. Because it is heavier than
air it will be concentrated and therefore most dangerous at
ground level.
