About 80% of the fire deaths are attributed to suffocation by toxic gas and heat. An individual's possibility of survival decreases 7%-10% every minute he/she is trapped in a fire. How to help victims escape quickly from the fire, while connect firefighters for rapid rescue is the problem we want to solve. Bright direction is a fire escape system, as well as a mask with direction indication, smoke-proof function. Victims can find the escape route in a short time with the mask that isolates the toxic gases contained in heavy smoke in a fire. Firefighters can find out the number of victims trapped in the fire and find escape routes through the APP-connected instruction cabinet that tells the number of mask in use, to determine whether to send more rescue workers, or which entrance to enter for search for more victims.
