Quantified evacuation route, timing, and capacity analysis
Emergency evacuation studies validate evacuation routes, timing, and capacity against credible major accident scenarios. Particularly critical for high-occupancy or constrained sites — using Pathfinder simulation and quantified hazard envelopes.
A structured, facilitated process — from scope definition through close-out — producing defensible, actionable outputs.
Define evacuation scenarios from credible-worst-case hazard footprints — fire, toxic, explosion, security; specify evacuation distance per FERA radiation / overpressure / toxic contour and AEGL-2/3 thresholds; align with COMAH / OSHA / EPA RMP.
Build occupancy profile per shift, area, and special population (mobility-impaired, contractors, visitors); align with facility siting study output and API RP 752 / 753 / 756 occupancy assumptions.
Design primary / alternate evacuation routes per NFPA 101 / IBC egress requirements — width, capacity, redundancy, weather protection; specify primary / alternate / off-site muster points outside credible hazard footprint.
Model evacuation time per Pathfinder / EVACNET / building thunder — pre-movement time (alarm response), travel time, mustering, accounting; benchmark against ASET (Available Safe Egress Time) per fire growth curve.
Design PA / siren / digital signage per NFPA 72 / EN 54-23; specify alarm zoning per evacuation phase (immediate vs phased); design intuitive signage per ISO 7010 / EN ISO 16069 photoluminescent path-marking.
Validate evacuation design via drill — measure actual evacuation time, identify bottlenecks, observe special-population assistance; specify improvement actions per ICS / NIMS AAR framework; align with COMAH / OSHA drill frequency.
