Operators of designated upper tier major hazard facilities must establish and implement a Safety Management System (SMS). Operators of designated lower tier major hazard facilities must prepare a Major Accident Prevention Policy (MAPP) and implement it using a SMS.

We have produced guidance to help operators of major hazard facilities build an effective Safety Management System and operators of lower tier major hazard facilities prepare and implement a Major Accident Prevention Policy.

An SMS is a comprehensive system used by the operator to ensure safe operation of the major hazard facility.

A health and safety policy is the core of an SMS. It sets out a clear high-level statement detailing your explicit commitment to preventing incidents, and includes broad aims, and performance targets. It establishes the framework, contributing to a high-quality safety culture at your facility.
