Comprehensive definition of safety shoes
Introduction
Government department of industrial accidents in 1997, statistical analysis shows that the total number of 43 305 injuries, 36% were due to marching objects, closed on an object or objects bumped by other causes arising, while the foot is often the hardest hit by injuries . In addition, the handling hot or corrosive substances and manual handling sputtering occurred accidentally crushed by falling objects, can also constitute damage to our feet. How exactly can reduce leg injuries in staff in the job opportunities? Wearing appropriate safety shoes is one simple and effective method. Of course, we still remember "personal protective equipment," the use, should not be considered as a substitute for engineering or administrative control methods to deal with hazards.
The existing occupational safety and health legislation in Hong Kong has not expressly provided for a particular occupation or process of staff are required to wear safety shoes can construction. But we can from different industries (for example: construction, catering, container storage and transportation industry and the shipbuilding industry, etc.) found that many employees have to wear safety shoes to work habits. Currently, many agencies have clear management or the employer of the company or individual, whether work-related accidents are caused by the loss, including human resources, injury, property damage and delays the progress of work, which ultimately led to a decline in productivity, affecting the competitiveness of the market . So in the absence of legal requirements, they also take the initiative to purchase safety shoes for employees, there is foresight. The Housing Authority also intends at its site that the promotion of safety shoes sport.
However, safety shoes can give full play to its protective function, you must choose, use and maintenance of increased attention to be. The following space will be above three points for a more detailed explanation.
Understanding of the standard safety shoes
Different regions and countries of the safety shoes specifications are slightly different. The more common standards are the following.
A European common market safety standards (EN344.1: 1992)
According to this standard test methods and specifications, safety shoes can be divided into three kinds:
. EN345.1: 1992: safety shoes for professional use, built-in steel toe, can prevent up to 200 Joule (J) impact.
. EN346.1: 1992: protective footwear for professional use, built-in steel toe, can prevent up to 100 Joule (J) impact.
. EN347.1: 1992: working shoes for professional use, there were no steel toe.
(2) American Standard (ANSI-Z41-1991)
According shoes for compression and impact resistance, a protective toe safety shoes can be divided into three kinds.
3 Australian Standard (AS / NZS 2210.1:1994)
This standard will be divided into four kinds of safety shoes, including:
Heavy-duty work safety shoes
. Medium-sized work safety shoes
. Light work safety shoes
Waterproof and safety shoes
4 Chinese National Standards
. G.B.4014 a 83 leather safety shoes
. G.B.7054 an anti-adhesive surface 86 to drop safety boots
5. Japanese standard (J1S-T-8015: 1983)
The current local labor market dumping shoes, mainly from Europe, so this article will focus on the European Common Market than the safety criteria.
Select the appropriate protective shoes
In the choice, we must first understand the staff, directly or indirectly injured foot major hazards, the following six:
1 is a hard, rolling or falling objects touch.
2 pierced by sharp objects or body of the shoe sole.
3 by a sharp object cut, and even the skin tear.
4 site lubrication, fell.
5 exposure to chemicals, molten metal, hot and cold surfaces.
6 in full of flammable gas environment, if improperly handled the release of static electricity, it becomes fuel source at any time, causing an explosion. In addition, the conductivity of the foot can also affect the employee's exposure to electrical devices, electrical shock hazard level.
Understanding of these information will help to choose the analysis of safety shoes.
When selected, the following factors must be carefully considered:
1 construction of the environment, such as:
. Site is wet?
. Field is uneven?
. Proximity to many exposed nails or other sharp wooden obstacles?
2. Contact materials, such as:
. Corrosive chemicals.
. Hot liquid.
. Bulky and difficult to control such goods or roller.
3. Use or exposure to machinery and equipment, such as:
. Electrical installations.
. Fork-lift truck.
. Sharp hand tools.
4 processes, such as:
. Dumping chemicals.
. Handle the high temperature liquid.
Welding work.
, Human handling.
After careful analysis, as listed in the operations staff directly or indirectly endanger the safety of foot issues. Then from the following number of shoes with protective materials and design elements related to matching, to meet you or your employees in the construction of the required protection.
1. Sole material
Common with all rubber, vulcanized like rubber, or PVC, etc.
. Sole role is mainly abrasion resistance, chemical corrosion, heat and oil, but the material properties are different, functioning also vary.
· The labor insurance shoes fitted with steel midsole, sole function is to prevent piercing by nails or hard objects.
In addition, some materials for the production of soles can relieve or reduce the generation of static electricity ESD speed. This can control the static electricity could cause an explosion or fire.
2. Sole design
In addition to using non-slip rubber-soled, the sole design of the slip function is also very important.
3. Body of the shoe material
Common in the leather, imitation leather, PVC and other synthetic fibers. These materials each have advantages, such as:
. Leather body with more durable by grinding and wearing more comfortable, but the anti-corrosive liquid damage function is poor.
. Leather applied to water, corrosive chemicals or other pollutants in the case, if the surface loss function will be affected.
, PVC is ideal for wet environments, but also easy to clean, but some chemicals can be broken down.
. Synthetic shoes are easier to clean and resistant to chemical decomposition.
4. Body of the shoe design
Reference to European standards, there are five kinds of styles.
A. shoes;
B. ankle boots;
C. Semi-knee boots;
D. knee boots;
E. legs and boots.
5 toe options
Safety shoes fitted with steel toe cap, the main function is to protect the toe from being struck or crushed. If staff are required to perform the heavier work, such as construction workers or employees carrying heavy goods, their safety shoes steel cap with the manufacture of material required corrosion resistance and up to 200 Joule (J) anti-impact performance.
Comprehensive foot injury in causing harm to have more awareness, and on the operating environment, materials, machine tools and construction methods, analysis of the factors identified as the foot of the staff on matters related to safety and hazards, trying to project and led by administrative means to control them, if not effectively reduce the hazards, the use of safety shoes will be inevitable.
Reference to the above information provided protective shoes, and consulting security professionals, safety shoes manufacturers or suppliers advice, make appropriate matching, so as to give adequate protection to the user. Along this process, with the publicity, training and monitoring, foot safety protection program is a basic model, applicable to all industries.
Use and maintenance of safety shoes
Correct use and maintenance, to ensure proper performance and safety shoes to play to maintain the user's foot health, so should pay more attention to the following matters:
1 safety shoes are not allowed to modify the structure.
2. Wear suitable safety shoes sizes, helps to maintain the wearer's foot health and footwear, durable period.
3 attention to personal hygiene, the user should be maintained clean and dry feet and footwear.
4 regular cleaning of safety shoes, but should not be used for solvent cleaning agents. In addition, the soles must always clean to avoid accumulation of dirt matter, because the soles of the conductive or antistatic material performance will be affected by how much dirt adhesion and bending of the impact.
5. Safety shoes store in a cool, dry and ventilated place.
Finally, we mention "personal protective equipment," the code:
1 should not be used as a substitute engineering or administrative control methods to deal with hazards.
2. Use of personal protective equipment shall meet the standards of design and appropriate to the job.
3 In addition to the appropriate choice, the correct use and maintenance of the function of play is equally important.
The Government Labour Department Occupational Safety and Health Ordinance is drafted under the "personal protective clothing," the regulations will enhance the use of personal protective equipment requirements.
