26.9.2 Storage and Handling
When not in use, portable magnetic 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 in clean, dry conditions which are free from injurious pollution or extremes of temperature. In particular it must be dry. Neodymium, used in most permanent magnets is extremely susceptible to corrosion.
They are stored off the ground and away from potential sources of damage. 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. 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 e.g. the face of the magnet.
When a magnetic lifter has been in storage and is to be taken into use, it should be checked by a suitably qualified and experienced person, see section 26.10.1 Pre-use inspection, for any signs of damage or deterioration before use. Any problems found should be reported to a competent person for resolution.
