SANS 10147 Audit
A regular plant audit is required to assess compliance to SANS 10147 and its sub-sections annexure G & H – a legal requirement of the OHS Act.
All Ammonia plants require to have an up to date SANS 10147 Audit which should be amended as follows:
- Every new installation, and
- Reassessed every three years, and/or
- After any alteration, incident or near miss incident.
This document forms an integral part of any Major Hazard Installation Report for the site and is a necessary requirement for plant assessment and the issuing of the mandatory Certificate of Compliance.
