Layout safety design shall ensure effective separation of hazardous areas from safe areas in which personnel may normally work or gather in the event of an emergency, or where emergency equipment is located.
As far as is practicable, piping, flanges, valves and other equipment with the potential for gas / vapor release shall be positioned to avoid jet fire impinging on critical items, such as escape routes, or other pressure systems. Equipment that is potentially more susceptible to leak or damage than others are positioned to minimize the impact of an ignited leak.
Layout Safety Review (LSR) shall ensure availability of escape routes. This shall ensure that there is no impact on existing escape routes. Existing escape routes shall be reviewed for adequacy due to addition of new facilities under the project and as far as possible the existing escape routes shall be maintained and where not possible additional escape routes shall be developed to achieve the safety goal of ensuring that all personnel from all parts of plant, can escape from an incident to a place of relative safety.
