There has been confusion over the use of long link chain but, after lengthy discussions, a little lobbying and some deep thought, a group of interested parties has worked in consultation with the Health and Safety Executive, a code of practice has been produced to clarify the correct type, use and inspection regime.
Along with the code of practice, a shorter document, designed to travel with chain, perhaps attached to flight case lids, sets out a method statement for correct use and notes on inspection.
