Labor knowledge - mechanical safety shoes
Machinery is employed in the production of safety shoes and work for the defense mechanical hazards foot injury while wearing protective shoes.
Classification
Currently, the use of a wide range of mechanical protective toe shoes, safety shoes are divided into protection, rubber boots and face anti-drop safety puncture-proof shoes in Class 3.
Protect the toe safety shoes in the toe with metal or within the header, with a defense against foreign objects on the toe injury squeeze function.
Anti-drop safety boots rubber surface water or ground in a damp environment, also in its inner toe with metal or header, with a defense against foreign objects on the toe injury squeeze function.
Puncture-proof shoes in the inner and the outer end of the bottom between the pads with anti-piercing, stabbed with sharp objects enough to the bottom of the defense function.
Selection
Can be divided in the choice of the appropriate choice of the type and grade, the selection of qualified products and view the quality of the appearance of three steps.
Select the appropriate type and level of
First, protect the toe safety shoes
Protected by protective toe safety shoes performance is divided into An1, An2, An3, An4, An5 five levels; by the production process is divided into adhesive, plastic injection, molding, seam and glued joints five.
Toe safety shoes for protection standards in force in LD 50-1994 "to protect the toe safety shoes (boots)." In the standard toe safety shoes to protect the front of the main technical performance of successful shoe pressure-resistant performance, impact resistance into a front-end shoes, folding outer end of the performance into a shoe outsole wear resistance and peel strength. Into the shoes into the front-end performance and pressure-resistant shoes is a front-end security properties of impact resistance, folding outer end of the performance into a shoe outsole wear resistance and peel strength is wear performance. Protect the toe safety shoes must meet the standards set forth in the technical performance requirements.
Protect the toe safety shoes may be needed, choose from the following two aspects:
1. Protection Performance:
Safety shoes protect the toe protection performance level 5 the highest level in An1, An5 the lowest level. High level of safety shoes to protect their front toe pressure and impact resistance of the technical indicators on high, like the protection of the toe, so the toe more likely to be injured or crushed, the more severe degree of injury job more high level of protection to use toe safety shoes, and some may be injured toe or crushed, the degree of injury is less serious work, you can use the low level of protection toe safety shoes.
2. Production process: the
Toe safety shoes to protect the production process is now generally use more glue and plastic, the bottom seam is generally used for tires and suede shoes, molded shoes are small, relatively new type of adhesive joints shoes, sports shoes like shape, gradually increased. Injection molding, adhesive seam shoes new, lightweight, wear-resistant polyurethane outsole material, the price is more expensive; adhesive shoes craft tradition, according to its style, timber, etc., the price varies; seam tire-soled leather shoes prices cheaper, but depending on its style, timber, etc., are also high and low. In addition, injection shoes, poor ventilation and adhesive, seam shoes breathe better, more comfortable to wear good quality shoes are very comfortable and stick joints. Production process is mainly related to the price, style, materials and comfort, does not involve performance, security, may need to use.
Second, the rubber safety boots hit the surface anti-
Anti-adhesive surface protection according to their performance, safety boots smashing into common type and level of light 2.
Anti-adhesive surface for safety boots hit the standard is HG 3081-1999 "anti-drop safety boots rubber surface." Standard anti-adhesive surface safety boots hit the main technical performance boots head pressure resistance and impact resistance, and the outer surface of boots at the end of physical and mechanical properties, water does not leak, etc., which boots the first pressure and shock resistance are security performance, boot surface and the outer end of the physical and mechanical properties, water resistance is not leaking wear performance. Anti-drop safety boots rubber surface must meet the standards set forth in the technical performance requirements.
Anti-drop safety boots rubber face the choice of protection is similar safety shoes protect the toe level of performance choices. Normal high level, light level is low. Likely to be injured or crushed toes, and the extent of serious injuries on the job should be used in ordinary type, while the toe is injured or the possibility of crushing small, and the degree of injury is not serious work, you can use light.
Third, anti-puncture shoes
Puncture-proof shoes, leather shoes and boots are divided into two types, and their protective properties are divided into premium, Ⅰ level, Ⅱ grade 3 level.
Puncture-proof shoes for the standard is GB 12017-1989 "puncture-proof shoes and technical conditions and puncture resistance test method", LD 50-1994 "protect the toe safety shoes (boots)," and HG 3081-1999 "glue surface anti-drop safety boots. " GB 12017-1989 provides a puncture-proof shoes and other anti-puncture strength of security performance, and for the use of performance shoes for rubber boots and physical and mechanical properties of materials were applied to the LD 50-1994 and HG 3081 -1999 in the relevant provisions. Puncture-proof shoes must meet the relevant requirements of these standards in the technical performance requirements.
Puncture-proof shoes may be needed, choose from the following two aspects:
1. Type
Shoes for the ground water of the place; rubber boots for the ground water of the place. Shoes in the production process, the options can refer to the protection toe safety shoes.
2. Protection performance level
The highest grade anti-puncture shoes, Ⅱ grade minimum. Puncture-proof shoe protection performance level can refer to the choice of safety shoes protect the toe of choice.
The selection of qualified products
Protect the toe safety shoes, rubber boots and face anti-drop safety puncture-proof shoes are of special labor protection articles. National implementation of the special labor protection articles management and production safety signs licensing system. Therefore, the choice, first make sure that the product's manufacturer issued a national security certificate and production license mark. On this basis, and then check whether the product manufacturer's name and address, safety signs, production license number, production date, production number performed by standards, product certification and is accompanied by instructions, special attention to see the shoes whether the product name or "protecting toes," "anti-drop" or "puncture-proof" and so forth, shoe and protective levels of performance, such as "An2" "Normal", "super" and so on. In addition, in the purchase, the dealer should also be required to produce the product in the test report, as well as the manufacturer of the product safety signs copies of certificate and production license (the original product to provide direct) and viewing period, and requested distribution 3 copies of this information to provide a copy of.
View appearance quality
Determine the mechanical protection appearance quality is also an aspect of the merits of quality shoes. Generally look at whether to help the disabled face, color is uniform, whether there is heavy needle and line, jumpers, broken, pin code is uniform; help end whether there is a plastic, off-line; soles and rubber surfaces have been sulfur , less sulfur, sulfur spray; within the header is skew; and so on.
Use
1. Protect the toe safety shoes should help prevent water wet surface, so as to avoid mildew and impact protection.
2. Protect the toe safety shoes should be worn to avoid contact with corrosive acid substances, anti-drop plastic surface wear safety boots should avoid contact with sharp, high-temperature and oil, acid, alkali or other corrosive substances, puncture-proof wear shoes should avoid contact with oil, acid, alkali or other corrosive substances, in order to prevent shoes (boots) are damaged, the impact protection performance.
3. Mechanical protective shoes in storage, should be placed on dry and ventilated warehouse, stacked more than 20cm off the ground and walls, leaving all the heating element 1m away, avoid direct sunlight, rain and moisture, as well as by the oil, acid and alkali or other corrosive the impact of substance.
4. Toe safety shoes to protect the storage period of more than 2 years (from date of manufacture), sampling should be standard, certified before use.
5. Mechanical service life of protective shoes on working conditions, work environment and the different types and so on. Usually in the local labor protective equipment configuration standard types of machinery for the duration of the use of protective footwear has the requirement that the payment period can not exceed the specified period. Who have not traveled included in local standards of labor protection articles configure the types of jobs, or no place to configure the standard labor protective equipment, production and business units according to the national standard GB 11651-1989 "labor protective equipment selection rules", and reference to other parts of the labor protection products with standards, develop the issuance of this unit standard. Of course, the machine can continue to use protective shoes, or the extent of damage depends on whether its impact on performance and minimum wear protection performance to decide.
