The air in the bottle of the TEMSC is to allow the boat to clear the immediate area in a battened down condition so as to be free from toxics or harmful gases. Provided the boat is correctly battened down and sealed the air will last for a period of 10 minutes and will tend to pressurise the inside of the craft. This is expected to provide enough time for the boat to head upwind into a clean atmosphere.
