According to the statistics of BureauofLabor of the United States: foot and leg protection: 66% of workers with leg injuries did not wear safety shoes, protective shoes, 33% were wearing casual shoes, and 85% of injured workers were unprotected due to item hits. Part of the boot. To protect the legs from damage from falling objects, rolling, sharp objects, molten metal, hot surfaces, and slippery surfaces, workers must use appropriate foot restraints, safety shoes, or boots or leggings.
When choosing a safety shoe, you can follow the following 5 points:
A. In addition to the appropriate type of protective footwear, it is also necessary to fit the foot and wear it to make people feel comfortable. It is very important to carefully select the appropriate shoe size.
B. Protective shoes should have a non-slip design, not only to protect people's feet from injury, but also to prevent accidents caused by the operator being slipped.
C. Various protective shoes with different performances must meet the technical indicators of their respective protective performance, such as the toes are not bruised, the soles of the feet are not stabbed, and the insulation is required. But safety shoes are not omnipotent.
D. Before using protective shoes, carefully inspect or test. In electrical and acid-based operations, damaged and cracked protective shoes are dangerous.
E. Protective shoes should be properly kept after use. Rubber shoes should be rinsed with water or disinfectant and dried to extend the service life. The sole of the safety shoe is generally molded by a polyurethane material, which has the advantages of acid and alkali resistance, water resistance, oil resistance, insulation, wear resistance and light weight. 3 times more wear resistant than ordinary rubber soles. It is soft and light, and weighs only 50%-60% of the rubber sole. Different safety shoes have different application scopes and different functions: the safety performance of the protective toe safety shoes is AN1, suitable for loading and unloading, mining, petroleum, quarrying, metallurgy, port, machinery, construction, forestry, chemical industry, etc. The puncture-proof safety shoes have a puncture resistance of 1 grade and are suitable for mining, fire protection, construction, forestry, cold work, machinery and so on. Electrically insulated safety shoes are suitable for electricians, electronic operators, cable installers, substation installers, etc. Note: Suitable for working environment with power frequency below 1KV, working environment should keep the upper dry. Avoid contact with sharp objects, high temperatures and corrosive substances, and the bottom must not be corroded and damaged. Anti-static safety shoes can eliminate static electricity accumulation in the human body and are suitable for use in flammable workplaces, such as gas station operators and liquefied gas filling workers.
Note: It is forbidden to use as insulated shoes; wear anti-static shoes should not wear insulated wool stockings or use insulated insoles at the same time; anti-static shoes should be used together with anti-static clothing; anti-static shoes should not be used for more than 200 hours. The shoe resistance value is tested once. If the resistance is not within the specified range, it cannot be used as an anti-static shoe. Acid and alkali resistant safety shoes are suitable for electroplating workers, acid pickers, electrolysis workers, liquid distributors, chemical operators, etc. Note: Acid and alkali resistant shoes can only be used in acid and alkali working places with low concentration; avoid contact with high temperature, sharp damage to the upper or sole leakage; apply water to wash the acid and alkali liquid on the shoes after wearing, then Allow to dry and avoid direct sunlight or drying.
Before choosing, we must first understand the main hazards that cause direct or indirect injury to the staff's feet. There are the following six items:
A. Touched by a hard, rolling or falling object.
B. Pierced the sole or the body of the shoe by sharp objects.
C. Cut by sharp objects and even tear the skin.
D. The site is lubricated and falls.
E. Contact with chemicals, molten metals, high temperature and low temperature surfaces.
F. Working in an environment full of flammable gas. If the release of static electricity is not appropriate, it will become a source of ignition at any time, causing an explosion. The right choice of safety shoes can be measured and selected from the structural aspects of the shoes:
A, shoe type: that is, the length and width of the shoe model, the width of the shoe body is tight with the foot.
B. Upper: Whether the softness of leather can be natural and suitable when walking.
C, shoe state: Whether the whole shoe state can stick to the foot without hitting the foot, loose and not off, flexible.
D, shoe body: common leather, artificial leather, PVC and synthetic fiber.
These materials have their own advantages. For example, the leather body is more durable and wearable, and it is more comfortable to wear, but the function of resisting corrosive liquids is not good. Faux leather can be used in the case of waterproofing, corrosive chemicals or other contaminants, but its function is affected if its surface is worn out... PVC is more suitable for use in wet environments and is also easy to clean. But it can be broken down by some chemicals.
E, toe cap: The toe cap of the safety shoe is equipped with a steel cap, the main function is to protect the toe from being injured or crushed. If employees need to perform more heavy work, such as construction workers or employees carrying heavy goods, the safety shoes and steel caps must be made of corrosion-resistant and 200-joule (J) impact resistance.
F, inner pad: Whether the correct use of vibration-activating function, sweat-absorbing function, massage function, health care function structure.
G, Neri: Whether the correct use of ventilation, waterproof, warmth, environmentally friendly functional materials.
H, sole: The material commonly used is all rubber, vulcanized rubber, or polyvinyl chloride. The soles are mainly resistant to abrasion, chemical corrosion, heat insulation and oil. However, due to the different characteristics of the materials, the functions are also different. The sole of the safety shoe is fitted with a steel sheet, which is used to prevent the sole from being pierced or hard. In addition to the use of a non-slip rubber sole, the design of the sole is also important for the anti-slip function. The soles are designed for regional and various environments. The substrate and anti-slip requirements are used in different degrees. For example, the environment is relatively non-slip, and the lightweight substrate is used. The outdoor site environment is reinforced with anti-slip, wear-resistant substrate and can withstand harsh environments. Subdivided into: white-collar, blue-collar, wages, administrative industry, light industry, heavy industry, construction site, tourism, service industry, etc.
