1. Safety Requirements for Eye and Head Protection Equipment

(1) To protect against the hazards of arc welding and flying sparks, welders must use a shade lens that meets the requirements specified in GB 3609.1 "Welding Goggles and Masks" based on the working conditions. The selected lens should provide adequate protection while allowing visibility.

(2) There are two types of welding masks: handheld and head-mounted. The mask and helmet shells must be made from non-flammable or non-conductive materials that are not irritating to the skin. The mask should fully cover the face and ears, ensuring no light leakage and a secure fit.

(3) For head-mounted masks used in various arc welding or overhead welding operations, the weight should not exceed 560 grams to ensure comfort during prolonged use.

(4) Auxiliary welders should wear appropriate masks and protective glasses that match the required shading levels depending on their specific tasks and environmental conditions.

(5) During gas welding and cutting, the correct protective lens should be selected based on the thickness of the workpiece being welded or cut to ensure proper eye protection.

(6) When performing tasks such as grinding welds or removing slag, it is essential to use impact-resistant safety glasses that are less likely to shatter and cause injury.

2. Safety Requirements for Welder Workwear

(1) Welders should choose overalls that are suitable for the nature of their welding and cutting tasks. The clothing should provide both protection and comfort.

(2) Cotton canvas overalls are commonly used for general welding and cutting tasks. The standard color for workwear is white, which helps in identifying any contamination or damage.

(3) In gas shielded welding, where ultraviolet rays and harmful gases like ozone may be present, welders should wear work clothes made from materials such as thick wool or leather to prevent burns and overheating.

(4) For all-position welding, leather overalls are recommended to offer better protection against heat and sparks.

(5) When performing overhead welding, welders should wear neck towels, long-sleeved shirts, shoulder pads, and aprons made from flame-retardant materials. Additionally, shoe covers should be worn to prevent sparks from causing harm.

(6) The overalls worn by welders should remain dry at all times. Pockets should have lids to prevent tools from falling out, and the clothing should be intact without holes or gaps. It should also be free from oil or grease contamination.

(7) Synthetic fabrics are not suitable for welding and cutting workwear due to their flammability and lack of durability under high-temperature conditions.

3. Safety Requirements for Welder Gloves

(1) Welder gloves should be made from heat-resistant leather or a combination of cotton canvas and leather. The length of the gloves should be at least 300mm to provide full forearm protection. Wet or damaged gloves should never be used.

(2) In electrically conductive environments, insulating gloves or gloves with an additional insulating layer must be used. These gloves must pass a voltage test of at least 5000V before being used.

4. Safety Requirements for Welder Protective Shoes

(1) Protective shoes for welders must be insulated, heat-resistant, non-flammable, and slip-resistant. They should also provide good wear resistance.

(2) Rubber shoes used by welders must pass a 5000V insulation test. In flammable or explosive areas, the soles should not have metal studs to avoid creating sparks from friction.

(3) When working on wet surfaces, waterproof rubber boots rated for 6000V and tested for safety should be worn to prevent electrical shocks.

5. Additional Protective Equipment for Welding and Cutting

(1) At welding and cutting sites, arc radiation and splashing slag can impair visibility. Therefore, arc protection rooms or screens should be installed. These screens must be made of non-combustible materials and painted black or dark gray. They should be at least 1.8 meters tall with a 25cm ventilation gap at the bottom.

(2) When working at heights or in areas where falling is possible, the safety belt used must meet the standards set by GB720 and GB721 "Safety Belt." The safety rope hook should be properly secured to a stable point.

(3) Welders' helmets must comply with the requirements outlined in GB2811 "Hard Hat" to ensure head protection during operations.

(4) Tool bags used by welders should be leak-proof, and commonly used tools like hammers, slag chisels, and wire brushes should be securely fastened to prevent them from falling or becoming loose.

(5) The power cords of mobile lighting equipment used by welders should be YQ or YQW type rubber-insulated cables. These cables must be undamaged, with no exposed wires. The lamp switch should be leak-proof, and the voltage should be determined based on site conditions or set to a safe level of 12V. Light bulbs should be protected by a metal mesh to prevent breakage.
