What are the classification criteria for labor protection work clothes?

Insulation workwear for live working is designed to protect workers who perform tasks on electrical equipment, including DC systems of corresponding voltage levels, with an AC voltage of up to 10 kilovolts. These garments must meet the technical specifications outlined in the "General Technical Conditions for Insulation Work Clothing for Live Working." They are essential for ensuring safety during high-voltage operations.

The insulating workwear must have excellent electrical insulation properties, along with strong tensile strength, resistance to tearing, puncture, aging, flame, and low-temperature performance. These features ensure that the garment remains functional and safe under various working conditions.

Anti-acid workwear is specifically designed to protect against acid and base exposure, providing hand protection in environments where chemical hazards are present. The quality of these garments must comply with the "Acid (Alkali) Workwear" standards. Any defects such as blooming, brittleness, stickiness, or breakage are strictly prohibited. Additionally, the workwear must be airtight, meaning it should not allow air to pass through under certain pressure.

Anti-acid and alkali workwear can be made from different materials, including rubber, latex, plastic, and dipped plastic. These options offer varying levels of protection depending on the specific application and environment. In some cases, waterproof and virus-resistant workwear can also serve as alternatives to anti-acid and alkali garments.

Oil-resistant workwear is typically made from nitrile rubber, chloroprene, or polyurethane. It is used to protect hands from contact with oils and other substances that may cause skin conditions like dermatitis, acne, folliculitis, dryness, pigmentation, and nail changes. This type of workwear is especially important in industrial and mechanical settings.

Welder overalls are designed to shield workers from heat, molten metal, and sparks during welding operations. Made from bovine, hog-tanned leather, or two-layer leather, they come in different finger styles, such as two-fingered, three-fingered, and five-fingered gloves. High-quality welder gear must meet strict appearance standards, with first-grade products requiring uniform thickness, softness, elasticity, and a smooth, firm surface free from greasy feel.

Anti-vibration workwear is used in industries involving hand-held tools like chain saws and rock drills, such as forestry, mining, construction, and transportation. These garments are designed to reduce the risk of vibration-related injuries, such as "white finger disease." They often include foam, latex, or air layers in the palm area to absorb vibrations. However, the design must balance comfort and functionality to avoid impairing dexterity.

Flame-retardant workwear was traditionally made from asbestos but is now largely replaced by fire-retardant canvas or other flame-resistant fabrics due to health concerns. These garments are used in high-heat environments, such as smelting and furnace operations, to protect against burns and fire hazards.

Antistatic workwear incorporates conductive fibers or is coated with polyurethane or polyethylene to prevent static buildup. This type of workwear is crucial in environments where static electricity could damage sensitive electronics, such as in the production of precision instruments, electronics, and research facilities. It helps maintain a controlled and safe working environment.
