What are welding curtains?
Welding curtains
curtains are screens that are treated to absorb ultraviolet radiation that can be set around the welding workstation to protect people in this area. Most forms of welding produce a bright flash of light that can be harmful to workers and passers -by. Short -term danger involves lightning burns in the eyes, while long -term exposure to ultraviolet radiation produced during welding can cause cancer. While a safe welder should always wear the right face shield and safety glasses at work, passers -by and others who work nearby may not always have the same protection. That is why the welding curtains are important. In the United States, their use is required by regulation on the safety and health protection at work (OSHA) 29 CFR, part 1910.252 (a). B) (2) (III). Regardless of where welding curtains are used, they must protect workers and others in the area from the ultraviolet Raditin Tom Be undisputed or FLAMeproof and must not reduce ventilation.
While the welding curtains can be permanently installed, many of them are portable, allowing people to configure their work areas to suit the work at hand. Some curtains are designed to hang from the rod on the rings, such as a shower hinge, so they can be opened or closed as needed. Another type of curtain is the welding screen, which is made of ultraviolet resistant material, which is stretched through a metal or plastic frame. Welding screens often have wheels that allow them to easily move.
The color of the curtain material is important; Different colors absorb different frequencies of radiation and blue light. For example, yellow curtains are good for low amperage welding, while green curtains are suitable for medium amperage welding. A well -stocked shop will have available material for all types of welding.Most screening materials are transparent, allowing workers to see their surroundings.
welding produces hot sparks and metal residues that can light fire. That is why the material in the welding curtain must be flameprof. It must also be established in a way that does not limit the emergency output routes in the event of a fire.
6 The welding curtains should be at least large enough to test the area where the welding is performed.
