Fire helmet

Gradually, more fire helmet hat shell top a named "stiffener" design, in order to increase helmet stiffness. So, once after falling object of fire, not only the helmet is not easy to hit a smashing, and impact of blocking and more on a floor, in other words, at least can reduce the number of firefighters concussion.

The appearance of the helmet, also have developed the brim of a helmet.

Before no brim type helmet is to head all packages in the fire helmet, benefit is the center of gravity, helmet closer integration with the head, but all will head wrapped in a helmet, also increase the weight of the helmet, is not conducive to heat dissipation of the head, and the protection range of the back of his neck. If he does not wear internal communication devices such as attachments, also for firefighters make communications difficult.

Imagine, if the firemen in the fire ground call for reinforcements, the need to take off the helmet to use such as intercom equipment, in addition to not convenient, more important, this time is one thousand incident, consequence is unimaginable.
