n the ship's domestic refrigerating system the compressor was cutting in and off frequently, temperatures were not being maintained and the chief engineer found that the Freon return line accumulator filter was choked and told us (2/E and 3/E) to clean the filter.
Also he mentioned that he had closed all the valves and sucked the gas from the accumulator to the compressor. So in a hurry we started slackening the bolts of the Accumulator-Filter. At the time there was a minor explosion and the high pressure Freon was released in to the the atmosphere of the restricted space. We received cold-burns (minor, fortunately) on our hands and shoulders and the skin color changed. Luckily our eyes not affected.
