Procedure is defined in ISO 45001 as “a specified way to carry out an activity or a process”.
The standard further explains that procedures may be documented or not. The procedure is essential for organizations so to avoid variations in their processes and standardize the way of doing a work or an activity.
When we say procedure is a standard way of doing a work or a process it means that the specific way has been validated by the organization as best for the purpose of delivering intended results.
See the list of mandatory documents required by ISO 45001, where documented procedures can be developed.
Thus the concept of procedure is important for occupational health and safety system since in many processes safe way of doing the work or activity should be defined by the organization as a procedure which can or cannot be documented depending on the reality of the organization i.e. the understanding, capability, and skill of the labor and the expertise involved in doing the processes.
