Combine ISO 14001 and OHSAS 18001

If an organization wants to have one comprehensive management system covering Environmental and Health and Safety (EHS), there are many common requirements which do not need to be repeated.

Because they are very similar, you can effectively combine and integrate ISO 14001and OHSAS 18001.

It is often more efficient to combine the two systems (EMS and OHSMS) into one, sharing the common clauses and procedures. We have considered this when creating documentation packages to simplify the implementation for an organization.

Rather than have parallel (duplicate) Manuals and other documentation we note where the user can just incorporate the OH&S and EMS requirements to the EHS Manual, procedures and instructions.
