Risk Analysis

Risk Analysis

To assess compliance to SANS 10147 –a legal requirement of the OHS Act

A SANS 10147 Risk Analysis is necessary on all Ammonia plants as follows:

  • new installation, and
  • every five years, and/or
  • after any alteration, incident or near hit incidents.

This document forms an integral part of a Major Hazardous Installation Report for the site and is a necessary for the issuing of a Certificate of Compliance for the plant.

  • A typical risk analysis would include the following: add
