The Safety Bulletin presents the results of a recent MAIB investigation, noting that CO2, a colourless and odourless gas, is highly asphyxiating: a 9% concentration causes unconsciousness within minutes and 17% concentration causes death in minutes.

The report issues a series of pointers to avoid CO2-related incidents, including servicing valves and regularly checking cylinder equipment. The MCA also suggests ensuring that pressure switches and alarms function correctly.
