If a fire breaks out in a building, finding the right way of escape in a short time is most crucial. As such, the Bleep Handle comes in useful in this emergency situation. Because of an air hole that is set in the centre of a Bleep Handle doorknob, convection occurs through the hole when one side of the door is on fire, which would naturally let out a sound to warn people of a fire in a room, or warn them against going in the direction of the sound. As a closed room is burning, oxygen is being consumed very quickly because of combustion. Soon, a huge difference in pressure between the two sides of the door can cause a ‘firestorm’ if one were to open the door. With the Bleep Handle installed, people can identify the conditions of a particular room before they enter, and this guards against a potentially dangerous situation.
