Avoid falling when stored in or knock against, because it may lead to damage of mask, helmet weaken shock absorption system function or damage to the surface protection coating. 

Prevention of occupational poisoning the use and maintenance of personal protective

The first step: According to exist in the form of poison and the main way into the human body , targeted for protection, personal protective equipment , including various types of respirators, safety glasses , goggles, protective visor , protective clothing , protective cap , protective skin protective gloves and painting classes and other supplies .

Step Two: If toxic substances enter the body through the respiratory tract , respiratory protection must be taken ; poisons absorbed through the skin , or operating in direct hand contact poison, should focus on skin protection , including the use of protective gloves and protective clothing ; if toxic irritation of the eyes , or practices lead to toxic spray hurt eyes, face , eyes should be taken , face protection.

The third step: in the workplace toxic substances , but also set the necessary sanitary facilities, such as toilet facilities , showers , changing rooms , etc., can be absorbed through the skin or on the local effects of toxicants great harm , but also with a skin and eye wash facilities .
Two . Use for their own personal protective equipment :

personal protective clothing choose us according to different occasions , the choice of the associated protective equipment and can not use, but according to the degree of occupational hazards and operating environment and other relevant factors , to make comprehensive choices, mainly from the following five aspects of how to select the appropriate their personal protective equipment .

( A ) the employer may respond to workplace occupational hazards identification, and workers may be exposed to a comprehensive assessment of the risks , in accordance with national regulations and standards requirements with a safe and effective personal protective equipment .

( 2 ) operating personnel using personal protective equipment shall meet the national standards, belonging to special labor protection supplies , to obtain special labor protection supplies safety certification mark , product packaging must be green LA certification mark.

( 3 ) use of personal protective equipment must be suitable for the user characteristics and operating environment requirements, to provide the necessary comfort and operating convenience.

( 4 ) various types of personal protective equipment when used in conjunction with each other can not interfere with each other .

( 5 ) without the use of effective , appropriate personal protective equipment is prohibited workers into high- hazard workplaces or rescue operations .

Equipped with personal protective equipment

personal protective clothing reserves each have the opportunity to participate at all levels of emergency treatment should reserve a certain amount of personal protective equipment , regular maintenance tasks to the scene of all staff are trained annually fit test . Regular or irregular organization drills. Filtration and adsorption ( tank ) should be at least more than the total number of C-level guards doubled , the choice of species should be able to cope with toxic substances that may be encountered amount needed , at least not less than 6 per class right, to replenish and updates.

   ( Two ) unexplained sudden public health incidents rescue package in dealing with individual protective equipment unexplained sudden public health incidents , at least two field staff to enter the scene , it should prepare two sets of rescue packages. Each should have the following equipment : ① closed airtight chemical protective clothing , ② portable gas operated full-face respirators , ③ chemical resistant gloves , ④ anti-chemical protective boots , ⑤ helmet , ⑥ portable gas analyzer .

   ( Three ) individual protective devices and the ability to respond to emergencies reserve is the basic guarantee of a public health emergency contingency plan clearly states the corresponding state of the individual protection requirements. According to the relevant laws and regulations, health administrative departments at all levels and disease control , medical treatment agencies to develop contingency plans, other public health emergencies occur the unit should also develop appropriate plans. In the plan -making process , to the tasks of the unit, and the presence of harmful factors , the development of a personal protection content contingency plans . Plans to deal with emergencies is to prevent a programmatic document , to have a strong operability in the plan , there should be a practical personal protection type, model , and enable mode . Public health emergencies have a greater chance occurrence , causative agent of emergencies caused by many kinds of emergencies in the actual investigation and handling of a variety of factors are often mixed . In the early stages of emergencies causative agent is not clear, thus increasing the protection of individuals handling emergencies difficulty . Disease control agencies and institutions in the Clinical Hospital after the occurrence of unexpected events bear rescue scene , investigation , and clinical management functions , so in all kinds of contingency plans in the individual protection work should have specific requirements, so disease control agencies at all levels , health supervision departments and clinical treatment units should have the corresponding reserves.

One , emergency field staff equipped with protective devices

   ( A ) the management and use of protective equipment training as an emergency response plan , equipped with personal protective equipment is only one part . On protective equipment management, and requires the use of protective equipment for staff training , etc., are also plans an indispensable component. Personal protective equipment only in the proper use and maintenance , based on to be fully protective effect. Protective equipment should be equipped with a tissue after use of the product for all users to accept training in the understanding of protective gear selection method , protection and use restrictions under the premise , to achieve a proper and workmanlike use . Personal Protective Equipment recommended various agencies at all levels should establish appropriate management mechanisms that regulate all aspects including the selection , purchasing, personnel selection , staffing, training in the use , maintenance, decontamination and disposal . When necessary, should also need to enter the dangerous field staff provide health checks , on the one hand to determine their ability to use protective equipment ( for SCBA and some air-purifying respirator for people with heart and lung function and physical requirements ) , and the other On the one hand timely detection of their health status , to facilitate early detection , early treatment.

   ( Two ) clinical emergency personnel protective device is equipped with multiple clinical emergency personnel should be equipped with C-level personal protection devices. For the treatment of victims of the contamination has been out of the emergency personnel , even if the victim carried insufficient inflicting poison threatening situations , also need to reach C-level protection standards . Levels of hospital emergency department or outpatient receives not only in the field of pollution has been removed by the patient , but also to seek treatment without receiving their decontamination treatment of the patient. Therefore, the hospital emergency department have a dedicated space to suspicious patients with decontamination of pollutants , while also equipped with a small amount of Class B protective clothing . Note that , C-level protective masks used filter element is the need to regularly updated over time can not play an effective protection. Protection of each of the filter element at different times, and poison this kind, concentration , and other relevant activities of the user . Right as emergency response operations use respiratory protective equipment, in order to ensure maximum protection performance , it is recommended to use as a disposable filter element generally , replaceable visor should be safe decontamination after repeated use is permitted .

   ( Three ) public emergency field personnel protective equipment with public emergency occurs, the first to enter the scene of the rescue personnel are police or firefighters generally . The former ( police ) present in our country is not equipped with dedicated anti-chemical personal protective equipment , so their responsibility is to the observed situation to give the latter ( firefighters ) . In case of fire , firefighters routine use of the " cut fire " or " from fire ," the device is intended to fire and to increase the heat resistance , in other harmful gases , liquid leakage , or in chemical fires, but also to take measures to control leakage , plugging leaks vent. Therefore, the fire agencies in addition to a certain amount of equipment, respiratory protection should also be equipped with a systemic protective equipment for its on-site with the fastest speed to complete rescue the injured, the task of controlling hazards .

Fire protective clothing standards

Fire protective clothing (hereinafter referred to as protective clothing) refers to the firefighters during fire fighting to protect their jobs and are usually dressed in clothes.

Performance requirements

Firefighters personal protective equipment and protective clothing standards of ordinary

Clothing protective equipment mainly refers to avoid firefighters subjected to high temperatures, drugs and other harmful environmental damage clothing, helmets, boots, hats, glasses and so on. There are fire-fighting suits, insulated clothing, avoid the fire service, disaster relief and clothing.

First, the battle suit and its supporting apparatus

Fire fighting services are firefighters put out the fire into the general fire fighting to protect themselves while wearing protective clothing, suitable for the fire "normal" state of use. Fire fighting services sub eighty-five style to the 1997 ceremony. Currently fire squadron equipped mostly eighty-five type fire fighting services, the clothing is divided into winter clothing, Xiafu, fireproof and waterproof clothing long fire suits four types, suitable for general fire fighting, does not apply near the fire and rescue operations help. 97 combat clothing is the latest successful research as a fire fighting service, with fire, flame, heat insulation, anti-virus and other functions, suitable for fire fighting and rescue work part.

1, fire on the human body

Burns, radiation, steam burns, frostbite, fatigue

2, fire fighter clothing work status

"Normal" state corresponds eleven firefighters operation in the face of the fire with water, or leaving the fire state a certain distance, the radiation heat flux 1.5kw/m2 below the temperature at below 60 ℃.

"Dangerous" state - the equivalent outside the room in a burning, or burning in a small building outside of the case with its radiant heat flux 1.5kw/m2 ~ 13.6kw/m2, temperature at 60 ℃ ~ 300 ℃ range.

"Critical" state - equivalent to similar violent burning in the vicinity of the crashed plane, or the occurrence of flashover situation encountered, the radiant heat flux 13.6kw/m2 ~ 200kw/m2, the temperature of 300 ℃ ~ 1100 ℃ range.

3, fire fighting services should have the protection and the associated measurement method

(1) Flame retardant (vertical burning test)

The 12-inch long strips of cloth placed in a propane flame to burn after 12 seconds, remove and measure the flame continued burning time, fire-retardant cloth carbonization time and length.

(2) Thermal Protective Performance (TPP)

① Thermal Protective Performance (TPP) Test: the fabric is placed convection and radiant heat source, the time required for recording two burns.

Time X heat source heat = TPP value

② TPP test method

TPP test is a 6 square inches of fabric placed on the total energy 2cal/cm2.sec thermal convection and radiant heat source, and then recording the time required to achieve the second degree burns, TPP value that is multiplied by the time cal/cm2. sec value. And vertical burning test different, TPP test can tell us simulate human skin through a variety of different fabrics to achieve two burns the amount of energy to be absorbed, ie the higher the value of the TPP fabric for the body exposed to high temperatures and the heat of the flame under the protection of the higher, the unit value of the TPP is the most direct thermal protective performance body connection.

③ hot human instrument thermal protection test (Thermo-man?)

To further simulate the actual extent of the flame burns the body, used to test the actual set of clothes in a simulated fire conditions, the degree of protection offered by the clothes. With this test, we can predict the body burns suffered two and three degrees, the body burns degrees lower, the greater the chance of survival.

Human body model test is to contain 122 temperature testers made from special glass-epoxy six inches high mannequin wearing fireproof suits, and make it the exposure to 12 propane flamethrower set synthetic 2cal / cm2.sec heat, the computer according to the temperature testers from 122 collected data to simulate human skin may be affected by the two and three degree burns and location.

4, protective performance

1) with a permanent protective function;
2) does not melt and does not have the function of combustion;
3) having the function is not broken;
4) resistance to chemical corrosion features;
5) durability;
6) comfort.

Fire insulation services security issues

Fire insulation services, sometimes referred to (fire protective clothing) is mainly for firefighters or other work in places of high temperature operating personnel compartment (anti-) thermal protection garments. According to Fu Jie fire equipment is understood that it is generally made from flame retardant fabric with vacuum aluminum composite materials are mixed together and made into, fire insulation services features: Asbestos, light weight, high strength, flame retardant , high temperature, thermal radiation, waterproof, abrasion, folding, and harmless to human body and so on, put on the garment can effectively protect the firefighters, hot places workers will not be even close to a heat source heat, flames, steam And burns a protective clothing.
According to the nature of disasters, each equipped with 8 sets of firemen combat uniforms. In addition, each firefighter is also equipped with F1 helmet, protective gloves, safety boots, breathing apparatus and other basic equipment.
