ISO 45001 Clause 8.1.3 Management of change states that the organization must establish processes for the implementation and control of planned temporary and permanent changes that impact OH and S performance . It also says this includes new products, services and processes , and changes to existing products, services and processes . That makes A true. It also supports B , because the clause is specifically about changes that impact the organization’s OH and S performance .

Statement E is also true. If the organization decides, after an emergency preparedness and response exercise, that it needs to change part of the OHSMS to improve OH and S performance, then that change has to be implemented in a controlled way under the organization’s management-of-change process. ISO 45001 links emergency preparedness with improvement and requires changes impacting OH and S performance to be controlled.

Why the others are false:

C is false because ISO 45001 does not limit management of change to planned changes only. It says the organization must also review the consequences of unintended changes and take action to mitigate adverse effects.

D is false because Clause 8.1.3 does not require retaining documented information of all changes . The clause requires establishing processes for implementation and control, but it does not state a blanket requirement to retain documented information for every change.

F is false because developments in knowledge and technology are explicitly included in management of change, not excluded.

G is false because changes are not limited to those identified by the organization itself; the clause also includes changes in legal and other requirements , and changes in knowledge or information about hazards and risks .

H is false because ISO 45001 explicitly says management of change applies to temporary and permanent planned changes.
