"This document addresses the risks to persons in occupied buildings within ASU and HYCO facility boundaries associated with pressure energy.
Pressure energy can be generated from ignition of flammable material that has been released into congested or confined area, and the sudden failure of pressure vessels.
This document is intended to provide guidance on determining the risk to persons in:
- new permanent or portable occupied buildings on ASU and HYCO facilities;
- existing occupied buildings from a new ASU plant, HYCO plant, or major modification added to an existing facility;
- an occupied building from a relocated ASU plant, HYCO plant; and
- a relocated occupied building.
It is also intended to provide guidance on how to address hazards from neighbouring facilities during the design of new ASU and HYCO plants.
The provisions of this document are effective as soon as hazardous materials are introduced into the ASU or HYCO facility.
While this publication is intended to provide an overview of the processes and evaluations used to determine safe location of occupied buildings, it is not intended to be a strict, prescriptive requirement.
As individual company processes, risk targets, facility layouts, and safety procedures vary, each facility should be evaluated individually to ensure safe location of occupied buildings.
Risk management and process safety assessment are complex subjects. Technology for determining the location of occupied facility buildings is still evolving.
Some aspects of this technology require the application of technical judgment as well as proven scientific methodologies.
It is the intention that this document be used by qualified personnel. Qualified personnel are those who have sufficient training and experience in hazard identification and risk assessment.
The publication is part of the programme to develop Globally Harmonised publications amongst Regional Gas Associations."
