What are the classification criteria for labor protection work clothes?

Insulating workwear for live-line operations is specifically designed to protect workers who perform electrical tasks on equipment operating at voltages up to 10 kilovolts. These garments must meet the technical standards outlined in the "General Technical Conditions for Insulation Work Clothing for Live Working." They are essential for ensuring safety during electrical maintenance and repair work.

The insulating workwear must have excellent dielectric properties, along with high tensile strength, elongation resistance, puncture resistance, aging resistance, flame resistance, and low-temperature tolerance. These features ensure both safety and durability under various working conditions.

Anti-acid and anti-alkali workwear is designed to protect hands from chemical burns caused by exposure to acids or bases. The materials used must comply with the specifications outlined in the "Acid (Alkali) Workwear" standard. These garments should be free from defects such as blooming, brittleness, stickiness, or tearing. Additionally, they must be airtight and resistant to leakage under pressure, making them suitable for use in chemical handling environments.

Anti-acid and alkali workwear can be made from various materials, including rubber, latex, plastic, and dipped plastic. Each type offers different levels of protection and flexibility, depending on the specific application. In some cases, waterproof or virus-resistant workwear can also serve as an alternative to acid and alkali-resistant clothing.

Oil-resistant workwear is typically made from nitrile rubber, chloroprene, or polyurethane. It is designed to protect the skin from contact with oils and other substances that may cause dermatitis, acne, folliculitis, dry skin, nail changes, or pigmentation. This type of workwear is commonly used in industrial settings where oil exposure is frequent.

Welder's overalls are made from bovine, hog-tanned, or double-layer leather to protect against heat, molten metal, and sparks during welding. They come in different styles, such as two-fingered, three-fingered, and five-fingered gloves. High-quality welder's uniforms require uniform thickness, softness, and elasticity, with a fine, even leather surface. Lower-grade options may lack these qualities but still offer basic protection.

Anti-vibration workwear is used in industries involving hand-held tools like chainsaws or rock drills, where prolonged vibration can lead to occupational diseases such as "white finger disease." These garments are designed with foam, latex, or air layers in the palm area to absorb vibrations. While thicker padding improves damping, it can reduce dexterity, so a balance between comfort and functionality is crucial.

Flame-retardant workwear was traditionally made from asbestos, but due to its harmful effects, it is now rarely used. Modern versions are made from fire-retardant canvas or other flame-resistant fabrics, suitable for use in smelting or furnace operations. These garments provide critical protection against high temperatures and flames.

Anti-static workwear contains conductive fibers woven into the fabric or uses long-fiber acrylic material coated with polyurethane or polyethylene. This design helps dissipate static electricity, reducing the risk of sparks in sensitive environments. Such workwear is widely used in electronics, precision manufacturing, and research facilities where static control is essential.
