Clause 6.1.2 is titled “Hazard identification and assessment of risks and opportunities”, and is separated into several subsections. Clause 22.214.171.124 is about hazard identification and talks about identifying the hazards present in the processes of your organization. Clause 126.96.36.199 is about assessing risks of the OH&S management system, both related to the hazards and all other risks. Clause 188.8.131.52 is about assessing opportunities of the OH&S management system. These are linked together under one clause not because there is a relationship between hazards an opportunities.
Clause 6.1.4 identifies planning activities to be put in place for clause 184.108.40.206 and 220.127.116.11. The link in this clause is due to the link of risks in clause 18.104.22.168 (against the hazards as well as the overall risks of the organization) that need to be planned for. The standar d is not saying the hazards could become an opportunity.
