Fire Zone Mapping
Equipment and/or areas within facilities can be identified and grouped into fire zones. These are areas where a pool or flash fire can be expected to occur and be contained by safety systems (passive fire barriers such as trenches and dikes, and active systems).
The following are some items that should be considered when establishing fire zones:
- Location of employees
- Fire, explosion, toxic health hazards of the processes and of the materials being handled
- Volume of material contained in the process, and how it is isolated during a fire
- Placement and effectiveness of active and passive fire protection
- Ability of employees to safely exit the fire zone, and access of firefighters and their equipment to the fire zone
- Possible fire hazards from adjacent hazards or zones
- Adequacy of a flare or atmospheric vent system to handle simultaneous relief from all PRDs within a fire zone
Fire zone drawings serve as an aid to clients in determining areas of the facility that already have or may need appropriate fire protection equipment (fireproofing, firewater monitors, adequate drainage, etc).
