As Ed pointed out OSHA has specific requirements for "certification" and /or "qualification". A major key for any employer is that they need to have on file & in written form documentation how, when and where they were qualified (certified). Generally this is a non issue - until an accident happens & OSHA comes into investigate - the ducks need to be lined up. Many employers "ain't got a clue" on this requirement or is it called risk(y) management.
