Has anyone heard of the HSE requirement to were snow chains on work boots or is it just a salesman trying to sell them?

Like DavidGault I've never heard/read that wearing snow chains/grippers is a HSE requirement. It's more likely to be an unfounded suggestion by one or more people selling such devices. However, as discussed in a number of past threads on this forum, it certainly makes sense for people to have and wear such devices when walking on surfaces affected by ice or hard compacted snow. I understand that postal workers are routinely provided with such devices and likewise some employees of some local authorities, e.g. home helps whose work includes walking between the homes of their clients and shopping for them. Please could anyone involved with postal workers, etc., confirm my understanding and perhaps expand on what such employees think of the devices? Also, such devices can help to minimise the risk of falls for everybody, not just people at work. Just think of the reduction in workload for A&E departments and hospitals, etc. (and savings to taxpayers) which could occur if more people wore gripper devices when appropriate. Though they're not especially trendy/fashionable items, forum users might think of gripper devices as worthwhile presents for relatives and friends, etc. Wintry conditions in the UK and Christmas will be back with us within 3 months!
