Fire Risk Assessment

Fire hazard and risk assessment services quantitatively and qualitatively evaluate fire and explosion risks in industrial facilities. Through QRA, fire and explosion scenario analysis, CFD-based fire and smoke modeling, and explosion and dispersion simulation, potential impacts and safety performance are verified. The results support risk mitigation strategies, safety separation distances, hazardous area classification, emergency planning, insurance risk assessments, and performance-based design approvals.

Hazard & Risk Assessment

Hazard & Risk Assessment is a fire safety engineering service that quantitatively and qualitatively analyzes inherent fire and explosion hazards in industrial facilities to prevent potential incidents and minimize operational risks. We perform Quantitative Risk Assessment (QRA), Hazard Analysis, and fire/explosion scenario modeling in accordance with international standards including NFPA, FM Global, and ISO. Utilizing advanced engineering methodologies, our analysis includes explosion overpressure calculations, thermal radiation impact analysis, toxic gas dispersion modeling, and Consequence Analysis to predict damage zones and impact ranges. Through worst-case scenarios and alternative scenarios, we develop comprehensive risk profiles for critical facilities.

Our assessment services cover a wide range of industrial facilities including petrochemical, refinery, manufacturing, logistics, power generation, and energy storage facilities. Based on assessment findings, we provide practical and actionable risk mitigation measures including fire and explosion protection system design improvements, safety separation distance determination, hazardous area classification review, and emergency response planning.

Additionally, we support clients in responding to risk assessments from industrial property insurers such as FM Global and Allianz, enabling the achievement of Highly Protected Risk (HPR) status and improved property protection ratings, resulting in reduced insurance premiums while simultaneously enhancing facility safety.

Fire and Smoke Modeling/Simulation

Fire and Smoke Modeling/Simulation is an advanced engineering service that predicts and analyzes fire and smoke behavior through computer simulation to quantitatively verify the fire safety performance of buildings and industrial facilities.

Utilizing internationally validated CFD (Computational Fluid Dynamics)-based fire simulation programs such as FDS (Fire Dynamics Simulator) and PyroSim, we precisely predict fire growth rates, Heat Release Rate (HRR), smoke spread patterns, temperature distribution, visibility reduction, and toxic gas concentrations. This enables scenario-based risk evaluation and calculation of ASET (Available Safe Egress Time) required for occupant safety.

In Performance-based Design projects, these simulations are used to verify smoke control system performance, evaluate evacuation safety, and establish fire spread mitigation strategies. They are essential tools for optimizing fire safety design in facilities with complex spatial configurations such as large atriums, underground spaces, tunnels, and industrial plants.

Simulation results are integrated with evacuation modeling to perform comprehensive safety assessments and serve as supporting documentation for performance-based design reviews by fire authorities and permitting agencies.

Explosion and Dispersion Modeling

Explosion and Dispersion Modeling is a specialized engineering service that predicts and analyzes explosion hazards from flammable gases and vapors, as well as atmospheric dispersion of hazardous materials, through simulation to establish explosion protection and emergency response plans for industrial facilities.

Using internationally recognized specialized software such as FLACS (Flame Acceleration Simulator) and PHAST (Process Hazard Analysis Software Tool), we model various explosion scenarios including Vapor Cloud Explosion (VCE), Dust Explosion, and BLEVE (Boiling Liquid Expanding Vapor Explosion). We quantitatively calculate explosion overpressure, fragment projection distances, and thermal radiation impact zones to assess potential structural damage and casualty risks.

Additionally, we perform atmospheric Dispersion Modeling for toxic gas and flammable material release scenarios, predicting dispersion ranges and concentration distributions based on meteorological conditions such as wind direction, wind speed, and atmospheric stability. This provides quantitative data essential for Process Safety Management (PSM), off-site consequence analysis, emergency response zone designation, and safety separation distance determination.

For high-hazard industrial facilities including petrochemical plants, LNG/LPG storage facilities, hydrogen energy installations, and battery manufacturing plants, we support the development of practical safety measures such as explosion protection design, pressure relief device capacity sizing, and explosion suppression system design.
