What are the protective functions of fire helmets?

Fire helmet is a kind of head protection equipment used in fire environment, which is different from ordinary helmets. According to the special environmental requirements of fire fighting and disaster relief, fire helmets must not only have the protective performance of ordinary helmets, but also be able to prevent the impact, corrosion, thermal radiation and fire of sharp objects. Some firefighting helmets are also equipped with air breathing apparatus and wireless communication systems to try to help firefighters put out the fire as soon as possible.

What are the protective functions of fire helmets

Fire helmets are used in the field of fire protection, and various hazards at the fire site should be considered, such as falling objects on the head, high temperature fire, smoke and oxygen deficiency, and unclear roads.

1. Anti-collision

The main reason is to prevent objects falling from height. The fire often fell from the air and hit the firefighter's head. It is likely to be life-threatening. Therefore, the utility model has excellent impact protection performance. It has a high-strength shell, high-density foam, wide-width cushioning cross straps and cap hoop I, uniform force cushioning net and cap IV. The impact intensity and local impact on the skull should be reduced as much as possible.

2. High temperature resistance

Due to the high temperature at the fire site, firefighters need to be fully armed to extinguish the fire. However, fire helmets need to protect the head, back and neck, which cannot be considered by firefighters. The fire helmet is a half helmet with a mask and shawl. The outer shell is made of flame-retardant reinforced polyamide fiber, the cap ring is made of plastic steel, the face screen is made of high-temperature resistant PC composite material, and the shawl is made of a double-layer structure of protective clothing fabric and heat radiation protection coating, which has excellent high temperature resistance. 3. Reflective

As there is smoke at the fire site, the fire helmet should be designed with obvious reflective signs or installed with lights. Fluorescent identification signs can help people trapped in the fire scene to find firefighters, and it is convenient for firefighters to find and contact each other in the dark or at night.

4. Absorb sweat

The high temperature at the fire site made the firefighters sweat. The top of the fire helmet is composed of a uniform net and a multi-stage adjustable cap ring. The soft and high-quality lightweight sheepskin material is used in contact with the skin, which can not only absorb sweat and breathe, but also is more comfortable to wear, avoiding skin allergies in hot and humid conditions.
