Mandatory documents in ISO 45001

Answer:
The use of the word “shall” in the requirement is indicating that you need to perform this function or activity, but this does not indicate that the ISO 45001:2018 standard requires you to document anything. Many processes which are required do not need to be documented, or have documented records. It is the use of the term “documented information” which indicates that there is a mandatory documentation requirement from the standard. Where the standard does not use the term “documented information”, but many companies include this in their OHSMS, we have included this in the document about mandatory documents of ISO 45001.
There is no one best way to document what is requi red in the OHSMS, so the best advice is to determine what will work best for you to be able to locate the information when needed. For larger companies, there is a good documentation structure discussed in the link below.
