2/ the ISO 45001 say to assess the OH&S opportunities, what does by mean of assess ,is it same when we say determine opportunities?
1/OH&S opportunities and other opportunities as per clause 188.8.131.52 is asking you to have a process to assess both of these types of opportunities. OH&S opportunities (clause 184.108.40.206 a) are any opportunities that may exist to improve your OH&S performance within your organization. This could include adapting work to make it safer, organizing work in way that reduces workplace injury or eliminating hazards that may exist in the workplace. An example would be replacing a cleaning chemical that is a known carcinogen with a safer chemical to clean parts in your facility.
Other opportunities (clause 220.127.116.11 b) come from outside of your organization such as changing legal compliance obligations or changes in external issues. An example of one of these other opportunities could be : if you find out that a supplier will not be able to provide you with a chemical that is critical for your product, and you can’t find th e chemical anywhere else. This could be an opportunity to find a safer chemical to replace the chemical that is being made obsolete.
In both cases, you assess these opportunities to decide which need to be addressed with planning actions (clause 6.1.4).
2/ To assess the opportunities is to decide what, if anything, needs to be done about them. You determine which opportunities exist, then you decide if you will do anything about the opportunity, and if so, you then plan to work towards achieving the opportunity.
As it relates to OH&S opportunities under 18.104.22.168, is this suppose to conincide with section 8 and the heirarch of controls --- and then circle back to 6.1.4 to execute a plan for improvement?
Plus, 22.214.171.124 is asking for a process - what would this process look like in a written format than auditor would want to see? ISO 31000 seems to lay out the risk assessment process in a much more user friendly manner that 45001 that jumps around and around.
The idea of the entire clause 6.1 is to assess the hazards, identify risks associated with the hazards (OH&S risks) as well as other strategic risks that could affect the OHSMS. Then you identify OH&S opportunities that could help the hazards as well as other strategic opportunities for the OHSMS. Following this you identify the legal requirements that could affect your OH&S and then plan to address all the previous items. This planning will include the controls needed for the hazards, and this is where the hierarchy of controls in section 8 is planned.
As for the risk assessment process ISO 45001 does not dictate how this is done as it may differ from industry to industry, and location in the world. Where you don’t have a direct legal requirement on how to assess risks you can certainly use ISO 31000 if you wish.
