“The morning after taking three months’ provisions aboard the vessel, the chief cook proceeded to fetch some meat from the refrigerated meat room. Upon opening the door, he was affected by the atmosphere of the meat room. His eyes and nose were severely irritated by the atmosphere and he immediately closed the door.

“The chief cook reported a ‘smell’ in the meat room to an officer who he encountered in the duty mess room. This officer subsequently entered the meat room to check for problems. After a period of 30 to 60 seconds he started to feel light headed and left the room.

“Further investigation by ship’s staff revealed the cause to be dry ice that had been packed with ice cream that had been received with the stores on the previous day. The remains of the dry ice were disposed of and themeat room thoroughly ventilated.

CHIRP Comment

There is continuing concern in the industry at the prevalence of accidents associated with entry into enclosed spaces. This incident illustrates that an apparently innocuous operation, in this case taking stores packed with dry ice into the meat room, could have led to a serious incident.
