LOPA Fundamentals Training

Overview

Since its inception over 20 years ago, LOPA (Layer of Protection Analysis) has become the tool of choice for identifying and estimating Process Safety gaps in industry where hazards are present and need to be contained.

Our course, which has been delivered both in-house and in public, will be present the key tenets of the LOPA technique, demonstrating how to make your facility appropriately safe and profitable.
