27.9.2 Storage and Handling
When not in use, vacuum lifters should be returned to proper storage. The general requirements are as recommended in section 1.7.2 Storage and Handling of this code and it is additionally recommended that:
They are stored off the ground in clean, dry conditions which are free from injurious pollution or extremes of temperature. It must be borne in mind that they can be heavy.
Equipment that is returned to stores in dirty condition should be cleaned and dried. In particular the vacuum pads should be cleaned and protected from contamination whilst in storage. Powerful solvents or cleaning agents should not be used and neither should direct heat. Surfaces liable to corrosion should be lightly oiled or otherwise protected.
When a vacuum lifter has been in storage and is to be taken into use, it should be checked by a suitably qualified and experienced person for any signs of damage or deterioration before use. Any problems found should be reported to a competent person for resolution.
Storage conditions should not be subject to extremes of temperature and must above all else be dry.
It is important that during use and storage between lifts, the vacuum lifting pads are kept clean as grit and other debris may damage the pads and impair their efficiency. A convenient way to facilitate this is to use a stand which holds the pads clear of the ground.
