In welding operations, metal elements and flux coatings & cores in the filler metals will bring various harmful substances and welding fumes because of the high-temperature welding arcs, which endanger the health of welders. The most common occupational diseases for welder's are pneumoconiosis and metal fume fever. The main form of transmission of these harms is through inhalation of welding fume into the lungs. The following are the specific manifestations of several welder occupational diseases:
① Welder's pneumoconiosis -the inhaling of a lot of mixed smoke and toxic gases such as silicon, silicate, manganese, chromium, fluoride, metal oxides, nitrogen oxides and ozone, will causes diffuse and fibrous lesions in the lungs.
② Manganese poisoning—early symptoms are fatigue, headache, dizziness, drowsiness, poor memory and autonomic dysfunction, such as slight tremors in the tongue, eyelids and fingers, and difficulty in turning around and squatting down.
③ Metal fume fever——The main symptoms are chills after welding work, followed by fever, fatigue, metallic taste in the mouth, nausea, itchy throat, dyspnea, chest pain, loss of appetite, etc.
④ Toxic gas hazard:
A. Ozone -it has a strong stimulating effect on the human respiratory tract and lungs.
B. Nitrogen oxides - they have a stimulating effect on the lungs
C. Hydrogen fluoride poisoning - immediate irritation of the eyes, nose and respiratory mucosa. Long-term exposure can produce bone lesions
In order to minimize the chance of occupational disease infection, welders must wear personal protective equipment in daily operations, including welding helmets, dust masks or gas masks, noise protective equipment, safety helmets, safety belts, protective clothing, welding gloves, work shoes and shoe covers, etc. The working environment is different, and the labor protection products we choose are different. Only by choosing the right labor protective products with specific functions can we better protect ourselves at work. Today we will mainly introduce how we can effectively protect ourselves in welding. What protective equipment should be worn:
(1) Head protection
Name: Full protective fireproof flame retardant welding hood
Specifications: 130G
Material: cotton cloth
Performance: It is made of fire-resistant and flame-retardant cotton cloth, and can resist welding spatters. It can still maintain fire-proof and flame-retardant properties after repeated washing.
Application sites: suitable for electric welding working environment, to prevent sparks and splashes.
(2) Welding helmets
Name: Fox Alloy True Color Auto Darkening Welding helmets
Material: high flexibility nylon
Performance: The welding helmets adopt a super-large high-definition true-color auto-darkening filter with easy replaceable protective lens. The dimming reaction time can be as short as 1/20000~1/25000s, which greatly protects our eyes from the welding arc. The welding helmets structure adopts high impact resistance and highly flexible nylon material which physically isolates most of the arc light and smoke. The head gear is light, soft and comfortable, and sweat-band is used to increase the comfortableness. Even if you use it for a long time, you will not feel tired on your head.
Application field: suitable for gas cutting, brazing, soldering operations in industrial, construction, petroleum and petrochemical, mining, machining, chemical, tool manufacturing and metal prefabrication industries such as grinding, cutting, drilling, machining, quarrying, tooling , polishing and other jobs.
(3) Dust mask for arc welding (welding fume protection)
Name: Industrial dust mask
Material: high-efficiency electrostatic ultra-fine filter material
Performance: High-efficiency electrostatic filter cotton technology is adopted to reduce the breathing resistance as much as possible on the premise of meeting the filtration efficiency performance.
Application site: used for the protection of particulate matter generated during welding, construction, mining, foundry, wood processing, electronics, pharmaceuticals, material handling and grinding.
(4) Protective clothing for arc welding
Name: Fox Alloy multifunctional welding aprons
Material: super durable pure cowhide material, high tension KEVLAR fireproof thread sewing
Performance: wear-resistant, fire-resistant and flame-retardant, prevent spark ignition, double the protection of personal safety and effective ventilation performance.
Application site: suitable for BBQ, welding, cutting, , foundry, petroleum, chemical industry, electromechanical, especially dangerous industries with flame or fire.
(5) Welding protective gloves
Name: Fox Alloy Conventional Welding Gloves
Material: 3 layers of cowhide leather
Specifications: Anti-scald and fire-resistant gloves for welding
Performance: It is made of cow neck leather with fireproof and heat insulation properties, and the inner layer is full of anti-scalding design to enhance comfort.
Application site: suitable for all kinds of welding and foundry industry, steel, handling work, etc. BBQ, wood working, etc.
(6) Labor safety shoes
Name: Anti-shock safety shoes
Size: 36-44#
Anti-skid level: SRA (by detergent anti-skid test)
Performance: It adopts fur leather shoes with non-slip design on the bottom. Steel plate toe cap, 15KN pressure resistance, 200J energy impact, double density PU sole, extremely comfortable, with air hole design, more comfortable to wear.
Application fields: light industry, heavy industry factory workshop, construction industry, tourism industry, service industry, etc.
