These fine neural networks allow us to perceive cold, heat, and pain in a few microseconds, and even feel the slightest vibrations of the amplitude of the hair. From the date of birth, the hand has not stopped activities, to the end of life, the hand can be 250 million times the average activity. However, we often overlook the importance of the hand, neglect its proper protection, so that in all kinds of incapacity to work accidents, hand injuries accounted for 20%. Therefore, the correct choice and use of protective equipment is very necessary. Hand protectors are one of the most finely dense organs in human organs. It consists of 27 pieces of bone, accounting for 1/4 of the total number of human bones, and muscle, blood vessels and nerve distribution and tissue are extremely complex, only the fingertip per square centimeter of capillary length can reach several meters, nerve endings up to thousands of.
Hand injuries type of hand injury, from a large area can be divided into 3 categories.
Traumatic injuries such as hand injuries, is due to mechanical causes of bone, muscle or tissue, structural damage, from severe severed fingers, bone crack to a slight flesh injury. If you use a tool with a sharp part, the manipulation of some large machinery or instruments with knives, sharp, etc. will result in the cutting of the hand and so on, the treatment, use of spindles, nails, screwdrivers, chisels, steel wire and so on will stab the hand, the hand is involved in the machine will be sprained, crushed or even rolled off the fingers.
Contact dermatitis This type of injury is mainly the injury of the skin of the opponent. Light person, cause skin dry, skin, itch, heavy person appears redness, blister, herpes, scar and so on. This type of injury caused by long-term contact with acid, alkali water solution, detergent, disinfectant, etc., or exposure to strong toxicity of chemical, biological substances, suffering from electric shocks, low-temperature frostbite, High-temperature Burns, fire burns and so on.
Arm jitter syndrome, white finger disease, such as long-term manipulation of hand-held vibration tools, such as Chain saw, rock drilling machine, electric hammer, pneumatic, etc., will cause such damage. The hand with the tool for a long time vibration, but also can cause damage to the blood circulatory system, and the occurrence of white finger disease. Especially in wet, cold environment this kind of situation is very easy to happen. Because the blood circulation is not good, the hands become pale, numb and so on. If the injury to sensory nerves, the hands of the temperature sensitivity will be reduced, tactile failure, and even cause permanent numbness. Glove material for various hazards that exist in the working environment, can choose different types of gloves, such as chemical substances for the prevention of gloves, for electrical hazards of insulating gloves, for high, low-temperature operation of High, low-temperature gloves, for cutting operations of the anti-cutting gloves, for vibration-resistant gloves such as work.
Glove material determines the protective performance of gloves, is the basis for the choice of gloves.
