Standards and application of labor insurance shoes

Different regions and countries have slightly different specifications for labor insurance shoes. The more common standards are the following.

1. European Common Market Safety Specification Standard (EN344.1:1992)

According to this standard test method and specifications, labor insurance shoes can be divided into 3 kinds:

.EN345.1:1992:Professional use of safety shoes with built-in steel plate in the toe cap to prevent impact of 200 joules (J).
.EN346.1:1992:Professional use protective shoes with built-in steel sheet in the toecap to prevent impact force equal to 100 joules (J).
.EN347.1:1992: Professional work shoes, no steel sheet inside the toe cap.

2. American Standard (ANSI-Z41-1991)

According to the resistance of the shoe to compression and impact, protective footwear with protective toe can be divided into three types.

3. Australian Standards (AS/NZS 2210.1:1994)

This standard divides labor insurance shoes into 4 types, including:

Heavy duty work shoes
.Medium Work Safety Shoes
Light work shoes
Waterproof shoes

4. The People's Republic of China National Standard

.GB4014 83 leather protective shoes
. GB7054 86 rubber surface fireproof safety boots

5. Japanese Standard (J1S-T-8015:1983)

The current labor insurance shoes that are dumped on the market in Hong Kong are mainly from Europe. Therefore, the content of this article will be based on the European Community Safety Standards.

Choose suitable protective footwear

Before choosing, we must first understand the main hazards that result in direct or indirect injury to employees' feet. There are the following six:

1. Touched by a hard, rolling or falling object.
2. Pierce the sole or shoe body with a sharp object.
3. Cut by sharp objects and even tear the skin.
4. The site is lubricated and falls.
5. Exposure to chemicals, molten metals, hot and cold surfaces.
6. Working in an environment that is flammable with flammable gas, if the release of static electricity is not handled properly, it becomes a source of ignition at any time, causing an explosion. In addition, the electrical conductivity of the foot can also affect the risk of electric shock when employees touch the power device.

Understanding this information will help in the selection of labor insurance shoes.

When choosing, the following factors must be carefully considered:

1. The construction environment, for example:

Is the site wet?
Is the site uneven?
Are there any wooden bars or other sharp obstacles near the nails?

2. Contact material, for example:

Corrosive chemicals.
Hot liquid.
Cumbersome and difficult to control the goods or rollers.

3. Machines and equipment used or contacted, for example:

Electric devices.
Fork lift truck.
Sharp hand tools.

4. Process, for example:

Dump chemicals.
Treat high-temperature liquids.
Welding work.
Human handling.

After careful analysis, we try to list the matters that can directly or indirectly endanger the safety of employees in the entire operation. Then choose from the following items related to the materials and design of the protective footwear to meet the protection you or your employees need for construction.

1. Sole material

Commonly there are all rubber, vulcanized rubber, or polyvinyl chloride.

· The function of the sole is mainly abrasion resistance, chemical resistance, heat insulation and oil resistance. However, due to the different characteristics of various materials, the functions are also different.
· The steel plate is installed on the midsole of the protective shoes, and the function is to prevent the sole from being punctured by nails or hard objects.
· In addition, soles made of certain materials can reduce the generation of static electricity or relieve the speed of electrostatic discharge. This controls the potential for static electricity to cause an explosion or fire.

2. Sole design

In addition to using a non-slip rubber sole, the design of the sole is also important for anti-slip functions.

3. Body material

Commonly there are leather, artificial leather, polyvinyl chloride and synthetic fibers. Each of these substances has advantages such as:

• The leather body is more durable and more comfortable to wear, but its anti-corrosive fluid damage function is not good.
• Artificial leather can be applied in the case of waterproof, corrosive chemicals or other contaminants, but if the surface is worn out, the function will be affected.
• PVC is most suitable for use in wet conditions and is also easy to clean but can be decomposed by some chemicals.
Synthetic fiber shoes are easier to clean and resist chemical decomposition.

4. Body design

    With reference to European standards, there are the following five styles.

A. shoes;
B. Ankle boots;
C. half knee boots;
D. knee boots;
E. Leg boots.

5. Toe selection

The main function of the protective footwear is to protect the toe from being bruised or bruised. If employees are required to perform heavy work, such as construction workers or employees handling heavy goods, the manufacturing materials of their protective footwear steel caps must have corrosion resistance and impact resistance of 200 joules (J).

Comprehensively understand more about the hazards that cause foot injuries, analyze the environment, materials, machine tools and construction methods of the operation, identify as far as possible the related issues and hazards to the employee’s foot safety, and try to use the Administrative methods are the first to control them. If the hazard is not effectively reduced, the use of protective footwear is unavoidable.

Refer to the above provided labor insurance shoes information, and consult with safety professionals, labor insurance shoe manufacturers or suppliers, etc., make appropriate matching, so as to give the user full protection. Following this process and cooperating with relevant publicity, training, and supervision is a basic model of a foot safety protection plan that applies to all walks of life.
