The Cromwell ER1 helmet is made of thermoplastic (high temperature resistant PVC). Visor and glasses - polycarbonate.

Clothing rescuers operating in the conditions of flying and falling objects of a collapsing object, works as follows.

Protective jacket 1 for rescuers also protects a person in the winter season from sudden blows from flying and falling objects of a collapsing object. The implementation of the frame racks 2 elastic allows you to mitigate the impact, protective shells 3 prevent injury to the skin of the lifeguard.

The ER1 helmet can also be used by paramedics, lifeguards on the water and civil defense - it is equipped with goggles and an accessory for optional ear protection. In addition, this helmet can be made for use in a helicopter (not by pilots), coastguards and airborne marine rescuers, etc. When developing the helmet, international anthropometric data were used for men and women - members of the fire and rescue teams. These data include differences of many ethnic groups, which makes this helmet convenient for use in all countries by representatives of any nationalities.

Using the proposed device will significantly increase the safety of rescuers in the conditions of flying and falling objects of a collapsing object.
