Differences between OHSAS 18001:1999 and BS OHSAS 18001:2007
The second edition of this OHSAS standard is focused on clarification of the first edition, and special attention is drawn to regulations of ISO 9001, ISO 14001, and other standards and publications related to health and safety, in order to boost compliance of these standards to the benefit of all users.
Draft of this OHSAS standard is made in compliance with the rules that have been set forth in ISO/IEC Instructions, Part 2.
The second edition shall cancel and supersede the first edition (OHSAS 18001:1999), which has been technically revised.
Principal changes in relation to the previous editions are as follows:
- The importance of "health" has now been given greater emphasis.
- OHSAS 18001 now refers to itself as a standard, not a specification, or document, as in the earlier edition. This reflects the increasing adoption of OHSAS 18001 as the basis for national standards on occupational health and safety management systems.
- The "Plan-Do-Check-Act" model diagram is only given in the Introduction, in its entirety, and not also as sectional diagrams at the start of each major clause.
- Reference publications in Clause 2 have been limited to purely international documents.
- New definitions have been added, and existing definitions revised.
- Significant improvement in alignment with ISO 14001:2004 throughout the standard; and improved compatibility with ISO 9001:2000.
- Term "allowed risk" is replaced by the term "acceptable risk" (see 3.1)
- Term "accident" is replaced by the term "incident" (see 3.9)
- Definition of the term "danger" does not refer any more to "damages of assets or damages of the working environment" (see 3.6).
It is now considered that such a "damage" does not refer directly to occupational health and safety management, which is the intention of this OHSAS standard, but that it belongs to the area of assets management. Instead, the risk of that "damage" that exerts influence on the occupational health and safety should be established by the process of evaluation of risks of the corresponding organization and controlled by application of corresponding risk controls.
- Sub-clauses 4.3.3 and 4.3.4 are merged into one sub-clause, in compliance with ISO 14001:2004
- A new requirement has been introduced for the consideration of the hierarchy of controls as part of OH&S planning (see 4.3.1).
- Management of change is now more explicitly addressed (see 4.3.1 and 4.4.6).
- A new clause on the "Evaluation of compliance" has been introduced (see 4.5.2).
- New requirements have been introduced for participation and consultation (see 220.127.116.11).
- New requirements have been introduced for the investigation of incidents (see 18.104.22.168).
The intention of this edition is not to include all necessary provisions of the contract. Users shall be responsible for its proper application.
Compliance with OHSAS Standard does not grant anybody the right to exemption of legal commitments.
