How big an issue is accreditation overall in OHSAS 18001 certification?
This varies with client expectations, competitive pressures and cultural norms in the different countries. For those organizations requiring an accredited certificate, BSI offers them for OHSAS under the Dutch Accreditation Body RvA and is actively seeking accreditation by UKAS and ANAB/SCC for BS OHSAS 18001:2007.
