The fundamental way to prevent hand injuries is to adopt automation, remote control, robots and other methods to avoid or reduce direct participation of hands in operations. The provision, use and quality requirements of protective gloves. However, in reality, it is currently impossible to operate without touching the hands. Moreover, taking other measures still requires certain technical and economic conditions as a foundation. Therefore, under the current circumstances, using protective gloves to protect the hands during operation can still play a certain safety protection role.
When a maintenance team of a certain power department in Zhengzhou City was conducting live-line work on a 10-kilovolt line, a 21-year-old worker who had just graduated from a university and started working less than a year ago, due to his disregard for safety and not wearing insulating gloves, accidentally touched the live wire with his left hand, resulting in electric shock and death from a fall from a height.
I. Overview of Protective Gloves
According to the "General Technical Conditions for Labor Protective Gloves" (GB 12624-1990), labor protective gloves (referred to as protective gloves) are protective equipment used by workers during work to protect the functions of their hands and arms.
(1) Structural features and functions of protective gloves
1. Protective gloves are lined and unlined
Unlined gloves offer an excellent touch, allowing the wearer's hands to work flexibly. Lined gloves (the lining is usually knitted, and the structural strength of the gloves is enhanced after adding the lining) can better prevent cuts, piercings and punctures, but the touch is not as good as that of unlined gloves.
2 Protective glove grip design
After the surfaces of the palm and fingers have been treated, they should be able to firmly grasp objects in both dry and wet environments. Usually, these two parts are respectively decorated with PVC dots, lines or other patterns to increase their friction, which is suitable for use by industry personnel who have certain requirements for the flexibility of their hands.
3 Design of the cuffs of protective gloves
Protective gloves mainly include tear-resistant and rollable cuffs, knitted cuffs and straight sleeves. The cuffs can protect the wrist and above. The standard safety cuffs are generally 6.35 cm in length, while straight sleeves are usually 11.43 cm or longer. Protective gloves are suitable for use by personnel in industries that frequently come into contact with corrosive substances.
