Welding is an essential process involved in any fabrication and construction work. It requires precision and concentration. Since you are dealing with dangerous fumes, gases, and electric work, special precautions should be taken to avoid any accident. Wearing a proper safety gear and using the appropriate equipment is necessary. Organizations like occupational safety and health administration issue special guidelines and regulations which every industrial and construction set up should adhere to. Welding helmets is the critical component of the safety gear. It protects our face, eyes, and hair from any damage caused due to any sparking and fume released in the welding process. To know all about this safety gear Welding Helmet Genius will be of great help.

If you are venturing into fabrication business or undertaking a welding project at your premises, there are a few hazards you should be aware of for the better precaution and safety of yourself and your employees.
• Electric shock or burning causalities: Welding involves working with high tension wires and metal components which are a poor conductor of electrical current. Thus they are exposed to the risk of severe injuries or fatal accident caused due to electric shock. During the process, an electrical circuit gets created. If by any chance the welding operator gets caught in this high voltage circuit, the current passes through their body which causes severe injuries and even death depending upon the intensity of voltage. Secondary voltage shock which is generated from an arc welding circuit is the most common cause of accidents at fabrication sites. Therefore, welding operators should use dry gloves, fiber or plastic insulation for holding the electrode. And position themselves at a safer distance from the metal welded and any wet surface.
• Fumes and gas generated during the welding process: The fumes released contain dangerous and complex metal oxides coming out of base metal and its coating. These gases can cause respiratory distress and other health hazards which can have a lifelong impact. Therefore proper masks and respirators should be worn. The fabrication project should be undertaken at a ventilated place with exhausts to control your exposure to these fumes. Regulatory authorities like ACGIH and OSHA issue permissible exposure limit which specify the amount of harmful substance in the breathing air which a welding operator is exposed on a daily basis and anything going above it should be reported and controlled by the supervision on an urgent basis. The industrial hygienist takes samples of breathing zone of the welding sites on a regular basis to ensure that the levels are below permissible level.
• Explosions and fire: The temperature at the welding arc can reach up to 10000 degrees Fahrenheit. Another concern is the heat and intensity of sparks generated from the process which can go to a length of 35 feet away from the location of fabrication. Therefore before starting up the welding process, we should do necessary checks like if there are any inflammable items in the close vicinity of gasoline, oil, paints, wood, hydrogen cylinders, etc. One should have complete knowledge about the positioning of the fire alarms, extinguishers and the length of the extinguisher gauge which would be handy in case of any sudden fire outbreak.
