You may find that your OHP is maintaining sufficient records on your behalf, but you do need to clarify ownership such that you can maintain continuity and legal compliance if you change OHP.

I maintain the OH contract for my company and it's quite simple once you are on top of things. If you have a good OH supplier behind you it makes the whole difference. I keep a matrix (excel spreadsheet) with names, what tests, times scales etc. If any body comes back requiring additional surveillance or they trip an action level this is recorded in the matrix. The main bulk of the records are held by the OH supplier, it's easier to comply with the data protection act if you don't have to keep large amounts of personal data on site. I haven't ever had any issues by working in this fashion and if I ever need access to the records they are only a phone call away.

Indeed, we interviewed them prior to the contract being signed and also inspected their premises. I am happy that they are compliant. Everything that we keep on-site is kept under lock and key.
