LAHTI PRO PROLINE MEGA TRYTON VULCAN Technical informations PAGE WWW.PROFIX.COM.PL 196 WELDING CLOTHING Clothing class Type of welding process Type of work on the workstation Class 1 Manual welding operations during which small amounts of spatter or droplets of molten metal are formed, e.g.: • gas welding, • TIG welding, • MIG welding, • microplasma welding, • soldering, • spot welding, • shielded electrode MA welding. Operating machines, e.g.: • oxygen cutting machines, • plasma cutting machines, • resistance pressure elding machines, • thermal spraying, • welding tables. Class 2 Manual welding operations during which large amounts of spatter or droplets of molten metal are formed, e.g.: • MMA welding (using alkaline or cellulose electrodes), • MAG welding (with CO2 or mixed gasses), • MIG (high-voltage) welding, • flux-cored arc welding, • plasma cutting, • gouging, • oxygen cutting, • thermal spraying. Operating machines, e.g.: • in enclosed spaces, • when welding/cutting operations require reaching above head height or take place in comparable difficult positions. Being class 2 Personal Protective Equipment, welding clothing has to be certified in EC type test for conformity with Directive 89/686/EEC. PURPOSE Welding protective clothing is required for welding works including welding, build up welding, soldering, bonding, thermal cutting of metals, and thermoplastics. During welding works, welders are at risk of glare, spatter burns, toxic and carcinogenic welding smoke and dust, electromagnetic field, UV and thermal radiation, electrocution, fire, poisoning, and skin, eye, and lung diseases. MATERIAL REQUIREMENTS Welding protective clothing is made mainly from flame resistant cotton fabrics, fire impregnated with high area density, and from natural leather dressed to make it fire retardant. DESIGN REQUIREMENTS Welding protective clothing should meet design requirements so as to minimise the risk of hot spatter penetrating the clothing: • Welding clothing should cover the whole body of the wearer during welding: the upper and lower part of the trunk, neck, shoulders, hands, and legs. • If the clothing consists of a jacket and trousers, the jacket should overlap the waistband at least 20 cm. The minimum overlap should be maintained during all activities and movements when at work. • Parts of clothing that act as additional protection such as neck cover, hood, sleeves, apron and gaiters, and gloves should be designed and used to prevent sparks and metal droplets from penetrating the clothing. • If clothing has pockets, they should be covered with flaps. • If trousers have pockets, these should be only side pockets that do not protrude from the lateral seam of the trousers more than 10°. • Trousers should not have cuffs. • The clothing should be designed to prevent electricity penetration for example through metal clips. CLASSES Two classes of welding clothing have been determined with strictly specified effectiveness requirements: Class 1: - protection against lower hazard welding applications and situations causing moderate exposure to spatter and radiant heat. Class 2: - protection against higher hazard welding applications and situations causing significant exposure to hot factors. The above-mentioned clothing classes were assigned types of welding application and types of process (type of machinery used) as per EN ISO 11611 to help select the right type of welding pro - tective clothing.
