Beer Carbonation

Safety Procedures

The brewer should only use pressure-rated vessels for carbonation/nitrogenation and must know the maximum working pressure of the tanks. Pressure-rated tanks are certified by the American Society of Mechanical Engineers (ASME) certifying its ability to withstand normal operation pressures. Tanks are equipped with pressure relief valves as a precaution against over-pressurization. Relief valves should always be mounted directly to the highest point on the tank. It is very important that no beer or foam come in contact with the relief valve, as contact can affect the operation of the relief valve, causing it to fail to blow off at the set pressure. Pressure relief valves should be inspected and tested on a regular basis, and they should be regularly cleaned to avoid buildup that can lead to malfunction. To avoid buildup from beer or beer foam, never fill tanks completely.
