Maintenance of fire service

1.take off after each use, check the condition of the fire service, focus on checking for wear.
2. if you want to remove residual dirt on the fireman equipment, with tap water and a mild soap, detergent if necessary.

Detergent used only in contaminated site, be careful, because detergents may damage the aluminized surface.
3. if the fire service has been and chemical exposure, or found to have a bubble phenomenon, you should clean the entire

aluminum surface. If oil or grease left on the fire service residue, then use a mild soap for cleaning.
4. fireproof clothing store before re sure to thoroughly dry, dry good is best not to fold.
5. if the surface of the fire service's thrown a small area is not very serious burn marks or wear and tear, you can use

aluminum gun repair. If there is damage to the external fire service, will have to replace the fire service.

Introduction of fire service

Fire service is referring to the United States NFPA1951-2001 Standards,Reference date The fire rescue service design and production of a new generation of fire rescue services. This firefighter gear has the following characteristics:
1 Shoulder, back, elbows, knees, hips and other parts are designed with reinforced layer, reinforcing area Total body area 40% Above;
2 Domestic first designed in cooperation with the fire department in Japan and exported to Japan disaster relief services;
3 360 Degree reflective design;
4 Permanent flame retardant, washable up 50 More times;
5 State Seismological Bureau rescue team used exclusively.

Fire helmet at all times and the evolution of

    Earlier HENGDA fire helmet is copper helmet . Its main function is to prevent brain bruise . 1800 in Berlin, Germany City firefighter wearing helmet atop the copper cone is pointed , you can fall in the above object distribution side . 50 years after the Paris firefighters helmet has a convex curved top bar empty room above objects can fall from decompression vent force, this helmet a great impact on the world. Firefighter helmet raised on China Palace train , also plays the same role that it had prevailed in the Qing Dynasty 200 years .
    19th century French also produced a helmet , body inside with leather lining made ​​of heavy falling dampening effect , lightweight helmet helmet than copper , but not as bright copper helmet , identifying poor performance in the field of fire .
    Later, in Berlin, Germany with a non-combustible fire brigade helmet plus fabric to edge after a software block above the combustion fall , let it fall into the firefighter 's neck, which has a trailing edge of the helmet by the Japanese Fire widely adoption.
    The United States is manufactured using fiberglass fire helmet , low cost , lightweight, have a variety of colors . U.S. fire brigade helmet with a white body color , red or yellow cap badge to identify good effect .
    With the development of firefighting practice needs and science and technology, more and more modern fire helmet , with a variety of functions , not only to protect the head, cephalic protection , higher strength , better impact resistance , but also lightweight and breathable. Timber mostly fiberglass -based, pay more attention to the bright color . Some also additional decorations, such as team logo , team numbers , and even additional light-emitting element . Some positions are still ear sound transmission components or additional ventilation devices.
    Interestingly, foreign fire dogs are wearing helmets when entering the scene to ensure the safety or identified ....

fire helmet use

        According to statistics , the number of injuries in the crash falling objects , 15% are due to improper use of a helmet . So you can not wear a helmet that protects the head from impact damage. In practical work should also be aware and do the following:
        ( 1 ) Any person who enters the production site or at the factory and outside engaged in the production and labor , must wear a helmet ( except for national or industry has special provisions ; special operations or labor , after taking measures to ensure that persons head from injury and after except for safety supervision department approval ) .
        ( 2 ) while wearing a helmet, the HENGDA fire helmet must be fastened with a guarantee under various state does not fall off ; helmet visors , must be consistent with the visual direction awry or may not be inclined to wear .
        ( 3 ) can not dismantle the cap member and the adjustment cap liner size , in order to maintain vertical spacing and horizontal spacing values ​​meet the requirements for the prevention of shocks peaked cause personal injury.
        ( 4 ) is strictly prohibited to put anything on top of the cap liner . Non-random changes in any organization helmet . Act as containers with helmet use is strictly prohibited . When the cushion helmet use is strictly prohibited .
        ( 5 ) helmet must have instructions and specify the use of premises for the rational use of operating personnel .
        ( 6 ) cap liner should be kept clean , clean, soapy water and when not rinse . After use can not be placed in acid , heat, sunlight, moisture and chemical solvents place.
        ( 7 ) the use of helmets suffered greater impact can not continue to be used.
        ( 8 ) If the cap shell , cap liner aging or damage , reducing the resistance to impact and penetration resistance performance , shall continue to be used to replace the cap.
        ( 9 ) can not be used as anti-static electrical helmet helmet use , in order to avoid the point . ,
        ( 10 ) helmet from the time of purchase date, year and a half with a valid plant cap . Plastic cap not exceeding two years , laminated fiberglass helmet cap and two and a half years rubber cap and cold cap , helmet to three and a half by car . These types of helmets over their useful life is generally prone to aging , the loss of the protective properties of the helmet .

Depending on the career choices helmet colors

Depending on the career choices helmet color , miners helmets with black , apparently do not meet safety ergonomic principles , because the mine lighting is poor, the black miners hat in the chiaroscuro obvious, easy to blurred vision and accidents.

    1 should choose qualified products
    Helmets must be produced according to the national standard GB2811, manufactured products through quality inspection departments should meet the standard requirements in order to issue the product certification. When purchasing a  HENGDA fire helmet, you should see whether it holds the production license and valid , whether Lao flag (LA).
    2 Select the appropriate species
    ( 1 ) helmet performance options based on : Each helmet has certain technical performance and its scope of application. For example, in low-temperature operating environment and select a helmet , you should choose low-temperature -resistant plastic helmet ( after environmental testing cold -20 ℃ ± 2 ℃ , shock absorbing properties and puncture resistance still meet the standard requirements ) and cold helmet ; at high temperatures high-temperature operating environment should choose plastic or fiberglass helmet helmet ( treated 50 ℃ ± 2 ℃ high temperature , shock absorbing properties and puncture resistance still meet the standard requirements ) ; contact with the grid in the power industry , electrical equipment should be selected with electricity insulation helmet ; operating in explosive environments should choose antistatic properties ( resistance of less than 1 × 109Ω) helmet .
    ( 2 ) According to the specifications, size selection.
    ( 3 ) the choice of style , big -brimmed hat and a large tongue cap applies to open-air operations , this HENGDA fire helmets has the role of anti- sun and rain . Small -brimmed hat for indoor , tunnels, culverts, roadway , forests, small-scale scaffolding superior activity , prone to collisions narrow brim places .
    ( 4 ) colors on the helmet , safety should follow the principle of psychology . International more common yellow with black stripe , is caused by warning signs, red is a restriction, prohibition signs ; blue display from the role . Therefore, the use of helmets ordinary jobs to adopt white , yellow, light green is appropriate. Miners helmets , coal habit with black color, which may be due to coal dust is black tarnish helmet can not see, but other colors are very easy to detect. But the miners with black helmet , obviously does not meet the safety ergonomic principles , because the mine lighting is poor, the black miners hat in the chiaroscuro obvious, easy to blurred vision and accidents.
    It should be in bright colors, easy to find cause alarm. Now miners cap color besides black , there are other colors, and stick reflective material on the helmet or light emitting material in order to attract attention in the dark lighting. Some departments use different color helmet to distinguish job title , such as security management personnel wearing a green and white cross marked helmets , maintenance personnel wearing orange helmets. Forest harvesting operations in space , red or orange helmet eye-catching , easy to be found. Radioactive operating environment is usually purple , brown helmet . Explosive workplace , the use of red helmets.

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.

The permeability and fire protective clothing

1. The concept of the permeability

The permeability is in unit time per unit area through clothing to describe the quality of the layer of water vapor. Fire protective clothing, for example, the speed of water vapor molecules penetrate clothing layer depends on the firefighters skin and water vapor concentration between fire fighter clothing outside air (or humidity), but also influenced by fabric physical resistance. Fireman moisture difference depends on exercise intensity (intensity, the greater the is, the more of the sweat) and climate environment. Fabrics resistance is a kind of performance of the material and its thickness used. In general, the thicker the fire protective clothing, the stronger the thermal protective performance, and clothing permeability is worse.

2. The structure and permeability of fire protective clothing

Fire protective clothing is by the outer layer, waterproof breathable layer, insulating layer, comfortable multilayer composite fabric. Among them: the outer fabric has high flame retardant and thermal properties, defense flame and high temperature; Waterproof breathable layer between the outer layer and insulating layer, can rise to prevent water to permeate insulating layer and the effect of discharge water vapor; Insulating layer with high temperature resistant heat insulation effect, make the firefighters from high temperature and radiant heat; Comfortable layer main effect is to make the firefighters wearing more comfortable. Multilayer structure to make fire protective clothing has good flame retardant, heat insulation, radiant heat penetration resistance and other properties, but at the same time permeability decrease fire protective clothing, and with the increase of the weight of the fire protective clothing, make more biological heat generated in the firefighters. The excess heat makes the body's temperature to rise, to the health of the firefighters.
