Isn't the magic 32 kg figure a legal requirement from Health and Safety
- think about it. It's the same virtually every where in the world so what would be the body that sets a law that applies all over the world?
Basically it's a number which has become internationally recognised - but 33 could be OK or 31 could cause injury, it depends on the conditions. If they allowed a baggage handler to lift say 35 and he injured himself, then under
UK law they could be prosecuted (by the state) and sued (by the handler) since the consensus of professional advice was 32. Same may be true under the laws of other countries. Where it gets interesting is if he lifted 35 and got away with it, under UK law even if it came to the attention of the HSE nothing would be done,
BUT if handlers started having a lot of injuries at 30 (maybe because of straining to fit it in to the shape of an aircraft hold) the HSE may start to take it seriously since actual events would have proved the previous advice to be doubtful. The Daily Mail, Lord Young and others would like to think that UK H&S law sets very specific standards for everything - it doesn't, the entire H&S at Work Act would quite easily slip into an envelope big enough for the average tour operator brochure.
there's two other things that need to be considered about maximum bag weight. First, the aircraft hold door size and floor loading standard - at some point a bag would be banned by the aircraft manufacturer even if the airline provided extra handlers and a fork lift truck!
And how do you get it to the airport? Have you ever tried to lift 32kg out of the boot of a car or on and off a train??? Until you check it in it's your problem!
