In all walks of life, whether in the territory, factories, such as kitchen, chemicals storage or processing place, human hands are the most valuable and the most universal tools. Because of this, hand the chance of injury also increased accordingly. According to statistics, the hand on work injury types and for many reasons, most of them hand injuries can be divided into the following categories:

1. The cut and stabbed

2. Wear

3. Burns/frostbite

4. Contact chemical

5. Get an electric shock

6. Skin infections

Select the appropriate protective gloves

In order to protect our double hands, avoid injuries at work, we must first to assess the risk of the work, as far as possible eliminate may hurt the hand of harmful factors, if you can't use the method of fundamental, improved such as hand tools, machine shield and improvement of process, to control hazards, so we adopt the appropriate protective gloves must be considered. Protective gloves for hand protection provided depending on the type of protective gloves, and different production methods and materials. Here are some evaluation protective gloves are suitable for the steps of:

Before choosing the appropriate protective gloves, first of all, to assess whether the gloves can effectively prevent the harm, and is suitable for use in this process. The harm of common are:

? physical hazards (such as cutting and stabbed, wear, burn/frostbite, get an electric shock)

? chemical hazard (e.g. chemicals)

? biological hazards (such as skin infections)

Identify the hazards, then need to select the appropriate type of protective gloves. Common protective gloves are:

? generally work with gloves (such as cotton or leather)

? treatment chemicals with gloves

? heat resistant gloves

? hardy with gloves

? prevent cutting with gloves

? shock with gloves

? electric gloves

In addition, also need to consider personal factors in choosing protective gloves. Such as protective gloves fit the wearer's hand? Workers feel comfortable after wearing protective gloves, etc.

Protective gloves must have good sense of touch, scalability and volumes grip, not slippery and easy to wear off, the material can be caused by such as cotton, rubber, nylon or leather, mainly depending on the nature of work and use, can't cut due to the use of protective gloves are likely to be involved in dangerous part of the rotating machine, such as drilling machine, lathe the rotation of the cutter.

Detailed interpretation of the European protective gloves specifications

The European economic community protective gloves can be divided into three categories: including "slight" (Minimal), the "Intermediate" (Intermediate) and "deadly" (Mortal). Explain the definition of the three categories below:

1. The design of simple protective gloves (applies only to "slight" risk)

Simple design of the protective gloves only applies to some low risk, such as building management personnel to wear protective gloves. This category of protective gloves can be personally test and verification by manufacturers.

2. Intermediate design of protective gloves (applicable to the "intermediate" risk)

Such protective gloves can provide protection for workers exposure to intermediate risk, such as some when handling to prevent wound or scratch protective gloves. The level of protective gloves must be taken to the recognized surveyor according to eu standards for testing and verification, if pass the test, the surveyor will issue a safety sign on protective gloves.

3. The design of complex protective gloves (applicable to "deadly" risk)

Such protective gloves can be exposed to a deadly risk provides protection to workers, such as some serious corrosion of liquid. This level of protective gloves must be done through the recognized surveyor according to eu standards testing and verification. In addition, the production of such other manufacturers also need to set up a set of perfect quality management system, to ensure that each product meet the testing standards.

When we want to use personal protective equipment, protective gloves is not exceptional also, want to make sure the personal protective equipment in conformity with the acceptance criteria. Protective gloves the specifications of the European economic community agreement provides different kinds and choice, are common in Hong Kong. When you purchase, you can refer to the following European standards of data.

1. EN 420 (protective gloves suitable for general purpose)

This standard are presented in detail the structure of the ordinary use of protective gloves should be, such as size, packing data. Protective gloves for other special purposes, such as electrician and surgical operation of protective gloves, are regulated by some of the more rigorous safety standards.

(a) purpose

Protective gloves not only to work for the wearer to provide maximum protection, nor to keep hinder their work.

(b) harmless

Protective gloves in addition to providing protection for workers to work outside, not can make other hazards to workers. This refers to the structure of the protective gloves and materials do not think the user's health and the health of any danger. Such as protective gloves pH (pH) should try to be close to neutral (i.e., pH is equal to 7); In addition, if, by chance, protective gloves contain any sensitive material, manufacturers should be clearly specified in the name of the material, and the damage.

(c) a good structure

The seams of the protective gloves do not reduce the protective function of protective gloves should be, for example, should ensure that chemicals cannot from these seams in hand, the hand injuries.

(d) storage

Excessive exposure to sunlight, oxygen and ozone, can make protective gloves early damage. So, protective gloves should be stored in the original packaging, and placed Yu Qingshuang and a cool place.

(e) size

Only suitable for protective gloves of the wearer's size, can exert its maximum effect. EN 420 according to the size of the European people's hand, ordered out the reference for the following size:

Protective gloves size Suitable for the shape of the hand size Hand round/length (mm) (mm) protective gloves minimum length (mm)

June 6, 220 152/160

July 7, 230 178/171

August 8, 240 203/182

September 9, 250 229/192

October 10, 260 254/204

November 11, 270 279/215

(f) measure the flexibility of protective gloves

The flexibility of protective gloves, protective gloves to within 30 seconds, picking up three times the smallest needles to decide. And the minimum value of the diameter of the needle is protective gloves flexibility.

(g), product data and volume label

EN 420 regulations on protective gloves need data has the following products:

Manufacturer's name, protective gloves, size, the name of the CE marking (" CE "is the European security specifications)

In addition, the packing bag of protective gloves must be printed with the following data: manufacturer's name, the name of the protective gloves, size, CE mark

Using the data

- simple design of the protective gloves need stamped with "applies only to a slight risk".

- intermediate design or the design of complex protective gloves need to be printed with one or more images, show that the special protective gloves to prevent harm.

Protective gloves - if only can provide protection for hand parts, must be clearly stated.

- manufacturer's contact address and telephone number, in order to provide detailed data to the user about the protective gloves.

If the length of the protective gloves do not meet above requirements, the manufacturer must clearly indicate the gloves are used as the special purpose.

If users need to ask for more data, manufacturers should provide relevant:

(I) all protective gloves and bags printed on some data;

(ii) the instructions;

(iii) any protective gloves within the material cause of sensitive data;

(iv) packing type;

(v) effective date.

2. EN 374 (to protect workers from chemical and microbiological hazard protective gloves)

This standard order clear protective gloves protect workers from chemical and microbiological specifications.

(a) penetrating

"Penetrating" refers to the chemical or microbial material particles through some there are holes, seams and other activities.

(b) soak

Protective gloves made of rubber or plastic sometimes not necessarily can stop the liquid infiltration. On the contrary, these materials may be like a sponge, soaked in the liquid, and then comes into contact with the skin. So, we should measure leaching protective gloves by liquid to wet, then comes into contact with the skin of the required time, i.e. it's "breakthrough time". EN 374 protective gloves "soak" can be divided into the following six categories:

"Break time" (minutes) to protect classes

> 10 grade 1 (Class 1)

> 30 level 2 (Class 2)

> 60 level 3 (Class 3)

> 120 4th level (Class 4)

> 240 level 5 (Class 5)

> 480 level 6 (Class 6)

For example, if wear "level 1 category" protective gloves, gloves will be immersed in ten minutes to soak, and then comes into contact with the skin. So, the higher the series of protective gloves, then you can stop the penetration of the liquid.

3.

EN 388 (protective gloves for mechanical damage protection)

This standard applies to all prevent by friction, knife and stabbed, tear, or shock caused by the physical and mechanical damage of the protective gloves. It also prevents workers' hands touch the electrostatic.

(a) chafing resistance

Protective gloves machine chafing required cycles.

(b) knife resistance

The cycles of slitting machine protective gloves need.

(c) tear resistance

Need to tear protective gloves.

(d) puncture resistance

To the magnitude of the Pierce point on protective gloves.

Protective gloves after more than four kinds of testing, they can be divided into "0" "performance index" - "5" six levels. The higher level of gloves, then said better performance.

Performance indices

Test 0 1 2 3 4 5

(a) chafing resistance (loop) < 100 100 500 2000 8000

(b) knife resistance (coefficient) < 1.2 1.2 2.5 5.0 10.0 20.0

(c) tear resistance (N) < 10 10 25 50, 75

(d) puncture resistance (N) < 20 20 60, 100, 150

4. EN 407 (provide protection for thermal hazard protective gloves)

This standard pointed out the protective gloves resistance to heat and fire.

(a) to prevent burning - to start the time needed for combustion protective gloves.

(b) to prevent contact thermal - refers to the wearer if access to the object of 100 ℃ to 500 ℃, also won't feel pain within 15 seconds.

(c) prevent convection heat - refers to protective gloves to prevent heat from the flame passed into the hands of time.

(d) to prevent radiation heat - refers to the temperature required for heat protective gloves to some point of time.

(e) to prevent hot melt metal small splash - refers to the hot-melt metal makes the temperature of the heat protective gloves to some point drips.

(f) to prevent major hot melt metal sputtering - refers to melt the metal through the protective gloves and come into contact with the skin needed weight.

5. EN 511 (to protect workers from the harm of frostbite)

Protective gloves to prevent infiltration of cold damage and water shall conform to the EN 511 standard, and through the test of (a) to (c). Likewise, each test with 4 "performance index". The higher the index, the stronger the ability to prevent cold.

(a) stop convection type cold.

(b) to prevent contact cold and frozen.

(c) to prevent water infiltration.

6. EN 421 (for a chance to come into contact with ionizing radiation or radioactive workers hand protection)

Have access to the personnel of ionizing radiation or radioactive substances, must be printed with the choose and buy the left image of protective gloves.

The gloves in line with the requirements of EN 421:

(a) protective gloves must contain a certain amount of lead, in order to prevent the ionizing radiation through the gloves.

(b) to prevent any water or liquid penetrant.

(c) prevent by ozone.

conclusion

Personal protective equipment is to protect workers from occupational accident harm one of the important measures. Prevent and eliminate all the risk factors, of course, is the most fundamental method of prevention. Compared with other control methods proved not line, to personal protective equipment (ppe) as the security of the last line of defence. When we to the risk assessment process, if still found that the use of personal protective equipment is required, then the need for correct selection of the standard to personal protective equipment, and trained personnel to use, repair and maintenance of personal protective equipment, in order to deal with good working condition, and cooperate with comprehensive security management plan, ensure the implementation of the personal protection plan.
