Accurate Simulation Scientific Verification
HEX desires to bring a better life for us and keeps evolving to verify HEX Dynamic Evacuation System in a more scientific way. It increases the building safety and reduces the causalities in fire effectively.
Precise Simulation
HEX applies the high-standard technology of the U.S. NIST to verify the Dynamic Exit Signs function. It builds the real field (including the firefighting devices) using the modeling technique of 10cm Level-of-Detail (LOD), which is used to conduct safety performance verification of fire production and simulate the fire evacuation. So far it has simulated many large fields and analyzed the data and results. It has successfully proven that the integration of a smart evacuation system can increase the people’s response ability and accelerate the evacuation effectively.

Import Scientific Evidence
After nearly forty years of efforts, global scientists finally make effective analysis on smoke in a fire. Moreover, it summarizes the FED (Fractional Effective Dose) values from a lot of biological experiments for the mixture of CO, HCN and HCL. The FED value indicates the minimum dose of gas mixture that may cause human injury in case of inhalation. If the smoke with FED value larger than 1 is inhaled, it may cause a fatality rate of over 50%. After years of experiments, it was determined to be the crucial point at which humans may be incapacitated during a fire.
FED Fatality Rate Curve: For the FED value of the two exits on both sides, the value has exceeded 1.0 on the left exit since the 304th second, indicating that the fatality rate is over 50%
FED Fatality Rate Curve: For the FED value of the two exits on both sides, the value has exceeded 1.0 on the left exit since the 304th second, indicating that the fatality rate is over 50%
HEX simulates the fire and the FED travel route of smoke and poisonous gases, and with the aid of weighted calculation of moving distance, it guides one to the safest and shortest evacuation route for each unit. Through HEX Dynamic Exit Signs, it conveys the information to people, so people won’t go into the dangerous areas in their state of panic.
