Posted By Merv Newman Michael, your risk assessment is going to cover eye, hand, foot and body protection in addition to exposure to fumes, heat, non ionising radiation, repetitive strain injury, manual handing, coshhh (exposure to chemical fumes during quenching)PUWR and, normally for farriers, risk of being kicked by a horse. This is the kind of situation we, in the safety industry would designate as a "challenge", or "a learning experience" I do hope this develops a good "thread" as it is an opportunity to compare "traditional" crafts with " modern" practice. I hope you are studying for a degree as I see "Masters" material here. Come on, you "practiitionners" and Fellows, what do you have to say ? Merv Newman
