The hand is a very important part of our body, and work and life are inseparable from it. From the time we were born, to the end of life, the hands have been constantly moving. It is a pity that we often ignore its importance and the protection of our hands, so that in modern industry, hand injury accidents have increased significantly, and hand injuries accounted for hand injuries in various types of work-related accidents 20% . This is a very alarming data, so the correct choice and use of protective gloves is very necessary.
Common hand injuries can basically be classified into three categories, namely physical injuries, chemical injuries and biological injuries.
① Physical injury is caused by fire, high temperature, low temperature, electromagnetic, ionizing radiation, electric shock and mechanical reasons. It has a great impact on bones, muscles, tissues and institutions, severe finger fractures, bone fractures and white fingers, etc.
② Chemical damage is damage to the skin of the hands caused by chemical substances, mainly due to long-term exposure to acids and alkalis, such as detergents, disinfectants, etc., and exposure to some highly toxic chemical substances.
③ Biological injury is easy to understand, basically it is a local infection caused by a biological bite.
How to avoid these hand injuries is to use protective gloves correctly and reasonably in the work. Now explain in detail 10 common protective gloves to help you choose the right gloves.
The first type: insulating gloves
Insulated gloves are used for live work. On the AC voltage of 10 kV or corresponding DC electrical equipment, wearing insulated gloves can perform electrical insulation work. As an insulating glove, it must have good insulation characteristics, and tensile strength, elongation at break, puncture resistance, aging resistance, low temperature resistance and flame resistance are all very good. The appearance and technology of the gloves must meet the requirements of the "General Technical Conditions for Insulated Gloves for Live Working", and strict production can achieve the required protection ability to avoid death due to high-voltage electric shock.
The second type: cut-resistant gloves
Cut resistant gloves mainly used in industries such as metal processing, machinery factories, cycling industry, glass industry and steel plate industry to prevent sharp objects from stab or cut hands. It is used mainly fiber and other high-strength fiber textile production, currently the most used is the US company DuPont Kevlar material. Kevlar material is a type of aramid fiber. The cut-resistant gloves made from it are softer than leather products, and have better heat resistance, fire resistance, cut resistance and wear resistance. Kevlar material is also a common material for body armor, and its protective performance is relatively reliable.
The third type: high temperature resistant flame retardant gloves
High temperature resistant flame retardant gloves it is the protective gloves used in high temperature environment, which are commonly used in smelting furnace pre-workers or other furnace types. It has three types, one is flame retardant canvas as the glove fabric, and the middle is lined with polyurethane as the heat insulation layer ; the other is made of asbestos material as the heat insulation layer, and the outside is made of flame retardant fabric as the fabric ; finally One is to spray metal on the surface of leather gloves, which can withstand high temperature and flame retardant and can also reflect radiant heat. High temperature resistant flame retardant gloves are available in three sizes, large, medium and small, which are divided into two-finger type and five-finger type.
Fourth: anti-static gloves
Anti-static gloves are generally composed of woven materials containing conductive fibers, and can also be made of long-fiber elastic acrylic braiding. The second type of glove needs to be attached with polyurethane resin on the palm part, or with polyurethane resin on the fingertip part or with a polyethylene coating on the surface of the glove. Gloves made of conductive fibers can quickly dissipate the static electricity accumulated on the hands. The second type of gloves with polyurethane or polyethylene coating is mainly not easy to generate dust and static electricity. Anti-static gloves are mostly used for product inspection, printing, electronic products, weak current, assembly of precision instruments and inspection work of various research institutions.
Fifth: Welder gloves
Welder gloves it is a protective tool to prevent high temperature, molten metal or sparks from burning into the hand during welding. The appearance requirements of welder gloves are relatively strict, with the difference between first-grade and second-grade products. The first-class product requires the leather body to be uniform in thickness, plump, soft and elastic. The leather surface is fine, uniform, firm, and consistent in color, without greasy feeling ; the leather body lacks full elasticity, the leather surface is thick, and the color is slightly darker. Second grade. Welder gloves are mostly made of cow, pig tamarin or two-layer leather, and are divided into two-finger type, three-finger type and five-finger type according to the difference of finger type. Welder gloves can sometimes be used as high temperature resistant gloves.
Sixth type: anti-vibration gloves
Anti-vibration gloves are used to prevent vibration-induced occupational diseases caused by vibration. In forestry, construction, mining, transportation and other sectors for hand-held vibrating tools such as chain saws, drilling machines and so prone to vibration of occupational disease - - "white finger disease ." These gloves add a certain thickness of foam, latex and air interlayer on the palm surface to absorb the vibration. The thicker the palm and finger pads, the greater the air volume, and the better the damping effect, but it is easy to affect the operation.
Seventh: acid and alkali resistant gloves
Acid and alkali resistant gloves can be divided into rubber acid and alkali resistant gloves, plastic acid and alkali resistant gloves, latex acid and alkali resistant gloves, plastic impregnated acid and alkali resistant gloves, etc. according to the material. It is a protective product to prevent acid and alkali substances from injuring the hands. Defects such as frost spray, brittleness, stickiness and damage are not allowed. The quality needs to strictly comply with the provisions of "Acid ( Alkali ) Gloves". Another acid and alkali resistant glove must be airtight. Under certain pressure, no air leakage is allowed. Waterproof gloves and antivirus gloves can be replaced with acid and alkali resistant gloves, which also has a good effect.
Eighth: oil resistant gloves
Oil-resistant gloves are used to protect the skin of the gloves from various skin diseases caused by oily substances. These gloves are mostly made of nitrile rubber, chloroprene or polyurethane. Some people who are sensitive to the stimulation of oils and fats should use oil-resistant gloves to avoid acute dermatitis, acne, chapped skin, dry skin, pigmentation, and nail changes.
Ninth: clean gloves
Dust-free gloves can prevent human static electricity from damaging the product during the production process, and are made of natural rubber. It can protect the product from the contamination and influence of finger residues, dust, sweat and oil stains during the production process, and effectively protect the product. The most common dust-free gloves in clean rooms are polyvinyl chloride (PVC) gloves.
Tenth type: anti- X -ray gloves
Anti- X -ray gloves are gloves personally worn by X -ray workers, and are made of soft leaded rubber that can absorb or attenuate X -rays and has good physical properties. Workers engaged in X -rays need it because they often receive X -ray radiation and are more harmful to humans. X -rays can damage the internal structure of the cell and cause life-long damage to the genetic molecules that is difficult to repair, and it is easy to induce cancer. It has a certain lethal effect on human blood leukocytes, resulting in a decrease in the number, resulting in a decline in the body's immunity, and it is easier to get sick.
