Description

Protective clothing for firefighting water area rescue

technical field

The invention relates to protective equipment for firefighters, in particular to a protective clothing for firefighting and rescue.

Background technique

At present, China's fire brigade lacks special rescue clothing for water areas. Rescuers can only wear combat uniforms inside their life jackets when they rescue. Although the fire fighting uniforms are waterproof, they absorb water and have great water resistance, so they are not suitable for wearing when launching into the water for rescue operations. Some fire brigades do not have strict regulations on the clothes of rescuers in water areas. In summer, rescuers usually only wear shorts and life jackets to enter the water, and in winter they wear autumn clothes, long johns and life jackets to enter the water. Although wearing less clothing can reduce the resistance in the water. It is more comfortable to move around, but it is prone to abrasions, scratches, punctures, etc. More importantly, the body temperature of rescuers in cold water will drop rapidly, sometimes it is impossible to complete water operations, and even threaten the life and health of rescuers.

It is understood that heat preservation and lifesaving clothing products have appeared on the market, but most of them are special clothing for lifesaving and heat preservation for operators on ships and offshore operating platforms in cold waters and harsh environments. It is made of waterproof fabric and heat-preserving buoyant material, which integrates underwear, gloves, and oil-resistant boots to cover the whole body except the face, and has the functions of buoyancy, watertightness and natural heat preservation. But this thermal insulation immersion suit has a large weight (about 7.5kg), slow putting on and taking off speed, and inconvenient activities after wearing, and is not suitable for the needs of rescue operations in fire-fighting waters. Countries such as the United Kingdom, the United States, and Japan have always attached great importance to the research and development of protective clothing for water areas. In recent years, in a few developed countries, there have also been water sportsmen, policemen, journalists, and underwater construction workers who need to carry out activities in or on water due to work. A new type of thermal insulation clothing worn at the time. These new types of clothing have different functions and characteristics, but their fabrics, thermal insulation layer, waterproof accessories, and processing technology all have high technical content, so the price is very expensive (the market price is equivalent to about 20,000 yuan). It is understood that China's research in this field is still basically in a blank stage.

In addition, through the binding of the relevant magic belt and the fixing function of the fixed adjustment belt, the protective clothing can be well fixed on the firefighter, and the firefighter will not move in series when performing any action, which will affect the rescue of the firefighter.

At the same time, the sealing rings of the cuffs and the neck are sealed and matched with the fireman's wrist and neck respectively, forming a closed, waterproof and breathable cavity in the fire protective clothing. In this way, during rescue in water areas, the cavity will well wrap the firefighter's body to form protection, and also enable firefighters to prevent water from entering the protective clothing during rescue work in the entire water area. The hot air is discharged through the clothes, so that the body is always kept dry, which greatly improves the safety and comfort of working in water.

In the rescue of water areas, a large amount of heat generated by firefighters in the protective clothing will penetrate from the inside to the outside through the fabric of the protective clothing, and form air bubbles on the surface of the protective clothing to complete the discharge of heat; because the overall protective clothing is waterproof Breathable, so during the ventilation process, the heat generated by any part of the firefighter will directly penetrate from the corresponding part of the protective clothing, so the heat generated by the firefighter in the protective clothing will be discharged outside the protective clothing in time without accumulation. It can ensure the comfort of firefighters very well.

If firefighters need to dive for a short time during water rescue, they can open the one-way exhaust valve on the shoulder or arm of the protective clothing, so that the air between the clothing and the body can be quickly discharged.

In addition, during water rescue, the eye-catching color of the protective clothing and the reflective strips on it can make it easier for other personnel to find fire rescue personnel at night or in low visibility conditions, increasing safety.

When carrying out rescue in colder waters, firefighters can wear the corresponding thermal liner first, and then wear the protective clothing, so that a warm layer is formed between the protective clothing and firefighters, so that fire rescue personnel can work at a temperature of 5°C. After soaking in water for 1 hour, the body temperature will not drop by more than 2°C, which greatly increases the safety of rescuers.
