材料：
An aircraft lift on board RFA Argus was loaded beyond its safe working load of 18.4 tonnes．There were no injuries to any personnel，or material damage to the ship or its equipment．
During a planned stay in port，500 compressed CO2 cylinders were required to be landed．These were normally stowed on a lower deck and needed to be transferred to the weather deck before being taken ashore．Before the vessel&39;s arrival in port，the planned operation was discussed between various officers and senior ratings，one of whom was to supervise final discharge of the cylinders from the ship．
Once in port，a senior rating gave instructions to three juniors to transfer a number of cylinders to the weather deck．He then left them alone to load the cylinders onto the platform. of an aircraft lift．The cylinders weighed 19.95 tonnes，which was greater than they had been instructed to load．In addition to this excess weight they added a fork lift truck weighing 5.5 tonnes．The lift was then raised．
When it reached the weather deck，the lift was unable to stow at the correct level．When investigated it was discovered that the load of both CO2 bottles and the fork lift truck was greater than its safe working load（SWL）and this had prevented the locking cleats at the flight deck（weather deck）engaging．
