List of mandatory documents required by OHSAS 18001

Note: In 2018 OHSAS 18001 was replaced with the new standard for Occupational Health & Safety Management System called ISO 45001. To learn which documents are required by this latest OH&S ISO standard, read the article List of mandatory documents required by ISO 45001.

Many companies go overboard with documentation in the belief that they need to document every single process that is in place in their organization, without realizing that this is not necessary to meet the requirements of the OHSAS 18001 standard. In the standard, there are several mandatory processes, but these are not required to be documented procedures. Also identified are many records that need to be maintained, which are generated by the processes of the Occupational Health & Safety Management System (OH&SMS).

Which documents are a must in OHSAS 18001?


Here are the documents you need to produce if you want to be compliant with OHSAS 18001:

These are the documents and records that are required to be maintained for the OHSAS 18001 Occupational Health & Safety Management System, but you should also maintain any other records that you have identified as necessary to ensure your management system can function, be maintained, and improve over time.

OHSAS 18001: List of mandatory documents

Commonly used non-mandatory documents

No system exists using only the mandatory documents. There are numerous non-mandatory documents that can be used for OHSAS 18001 implementation. However, I find these non-mandatory documents to be most commonly used:

While OHSAS 18001 does not require that you document all of the procedures, one rule of thumb when deciding if you want to document a process is this: if your organization needs a written document to ensure consistency between employees, then you should do so. In many cases this is the best way to ensure that your Occupational Health and Safety Management System is reliably implemented.

Documentation is important, but keep it simple

Documentation in the Occupational Health & Safety Management System is important to ensure that critical processes, where you need to make sure that all employees consistently do the same thing, are understood and repeatable. In order to make this work, it is wise to have these processes as uncomplicated as possible and presented in the simplest manner to make them easy to understand; often, using a graphical flow chart can suffice to relay all the relevant information quickly and easily. The less complicated the documentation, the easier it will be to ensure that all employees can deliver repeatable outcomes. In the long run, the old adage is often right: “The simpler the better.”
