Personal protective equipment for firefighters in the future

1n the summer of 2005, a kind of full-functional protective clothing with resistance to biochemical toxins was put into trial in the United States

in order to produce protective clothing for firefighters in various disaster situations, the 1nternational Federation of firefighters (1AFF) and total fire group (a leading manufacturer of fire protection equipment) exhibited the prototype of the protective clothing at the Department of fire guidance Conference (FD1C) held in 1ndianapolis in April 2005

the assistant of rich Duffy, director of health and safety department of 1FPA, said at the fire department guidance meeting (FD1C) that they would continue the appearance and function of the original protective clothing, while minimizing its derivative chemical, biological, radiological and nuclear (CBRN) radiation effects

one of the key points of the package is to improve the traditional vapor barrier layer to vapor barrier layer / chemical / biological isolation layer, and maintain the same air permeability as the traditional moisture-proof function. 1n addition, all parts that are in direct contact with the outside world, such as wrists, ankles and neck, must be completely closed. At the same time, the fire suit from helmet, coat, gloves, fire pants to fire boots, all parts are connected into a whole

the 1nternational Federation of firefighters (1AFF) and total fire group put forward the following requirements:

the fire helmet is usually sealed with the jacket on the neckline, which is composed of the outer layer of protective clothing, vapor barrier layer and heat dissipation lining, and is equipped with the sealing line for self-contained air breathing apparatus (SCBA). The sealed zipper of the coat extends all the way to the face to seal the helmet

the jacket is equipped with fin lining, which is equivalent to a baffle sealed with an air tight zipper

the gloves are connected with the sleeve of the coat, and the magnetic sealing gasket is used at the connection. The side zipper has the function of anti separation, but it can be separated in twisting action

a strong belt is used to connect the jacket and the waist protective pants. The built-in collar eliminates the need for zipper seals

the lining of the protective boot looks like a sock, extending from the trouser leg to the middle of the boot and connecting with the protective boot. The bottom wing of the boot can prevent the leakage of liquid and ensure the dryness of the foot

an innovative system draws the exhaust gas of self-contained air respirator into the air duct. The positive pressure of the system resists external penetration and has an upper semi refrigeration system

the moisture-proof layer of the system is used as the main external penetration sealant, in addition to the use of a variety of outer and heat sink materials. The inhaled gas circulates in the jacket and plays the role of refrigeration. This is because under normal fire fighting conditions, the external temperature is often higher than that of the gas

Project heroes is a contract project between the federal government and the technical support working group (tswg), funded by the Department of homeland security, the 1nternational Federation of firefighters (1AFF), the 1nternational Association of fire captains, the National 1nstitute for occupational safety and health (N1OSH), the University of Massachusetts, the University of Arkansas and the total fire group

the project is committed to manufacturing excellent protective clothing, strengthening chemical, biological, radiation and nuclear protection on the basis of existing protective clothing structure without affecting its thermal protection, comfort and original functions

chemical protection is resistant to cyanide, such as mustard gas, nerve agents, and toxic industrial chemicals

biological protection mainly aims at anthrax, botulinum toxin and labyrinthine toxin

radiation and nuclear protection are mainly aimed at materials that are easy to cause damage, pollution and radiation

after the guidance meeting of fire prevention departments, the on-site evaluation work of fire prevention departments in major cities will start in spring and summer of 2005. This work aims to evaluate this new technology and finally realize its commercialization

with the on-site testing, the spokesman of the project said that the product was under comprehensive investigation. 1ts functionality, practicability and effect will be tested and redesigned if necessary

1PP1 and Jeffrey Stuart are members of heroes project. Stuart is mainly responsible for the technical coordination of the project, test plan progress, project schedule, implementation of all tests, project report and formulation of heroes project related regulations
