Preventing Fires and Explosions<\/h3>\n\n\n\n
Where hot work cannot be carried out in a safe area, or where combustible material cannot be removed from the work area, a fire watch should be maintained during and after the hot work.<\/p>\n\n\n\n This watch should be maintained for at least 30 minutes after the completion of the hot work, but where an unintended ignition may be difficult to detect or slow to develop, this may need to be extended to 60 minutes.<\/p>\n\n\n\n Welding and cutting inside ships and other enclosed spaces is particularly dangerous as smoke from fires cannot escape and will quickly overcome people working nearby. Each year people are injured at work by flammable substances accidentally catching fire or exploding. Work which involves using or creating chemicals, vapours, liquids, gases, solids or dusts that can readily burn or explode is hazardous. The effects of an explosion or a fire in the workplace can be devastating in terms of lives lost, injuries, significant damage to property and the environment, and to the business community. The arc welding process requires a live electrical circuit. This means all arc welders using hand-held equipment are at risk of electric shock and electrical burns. The risk for MIG\/ MAG and TIG welding is much less, as the welding current is normally switched on and off using the trigger or foot switch. One culprit is damaged welding leads, When this happens, the electrical circuit is no longer contained. Arc welding uses an electrode cable that powers the welding lead and a ground cable to create that circuit. Damaged or improperly maintained equipment \u2013 such as cables or missing\/burned out insulators, or faulty connections \u2013 can cause shock injuries or electrocution. Another danger: Some welders attempt to replace a welding electrode or contact tip with their bare hands, instead of wearing a dry welding glove. Don’t become complacent and forget the basics. It\u2019s hot and you are sweating and you\u2019ve changed wire or contact tips hundreds of times without gloves, but now you are wet and things could happen.<\/p>\n\n\n\n Welding exposes workers to intense heat \u2013 often thousands of degrees \u2013 making burn injuries common. Wearing the proper personal protective equipment, along with inspecting and maintaining it, is a key step to preventing burns. This can mean making sure gloves and clothing don\u2019t have holes; using flame-resistant hearing protection; and not wearing clothes with cuffs or open pockets, where sparks or molten metal can become trapped.<\/p>\n\n\n\n Another source of burns is radiation, or electromagnetic energy, that reaches the skin. One form of radiation, ultraviolet rays, can be harmful to workers\u2019 eyes \u2013 resulting in \u201cwelders\u2019 eye\u201d or \u201carc eye\u201d (a reference to arc welding). Sometimes the effects are not felt until several hours after an exposure, warns the Occupational Health and Safety organisations. Recent laws and regulations regarding Fumes mean that lower exposure limits are a must for the workforce who are subjected to smoke and fumes from welding<\/a> and metal cutting.<\/p>\n\n\n\n International health organisations recognise the importance of preventing health risks associated with fumes and smoke generated during welding and thermal cutting. In many countries, strict personal exposure regulations and standards such as are heavily enforced to minimise worker exposure to hazardous metal particulate that can be present in welding fumes.<\/p>\n\n\n\n Ventilation and filtration are the primary solutions to mitigate employee exposure. Welding fumes are generated by a thermal process that creates a plume of suspended particles in the ambient air. When the fume plume cools, the particles enter the breathing zone affecting worker exposure. Properly designed capture and filtration systems protect worker\u00b4s health and assist in complying with local regulations and standards.<\/p>\n\n\n\n You can either use a mobile or fixed fume extraction unit<\/a> where the ducting arm acts as an exhaust to clean the air. Or you can have your own PPE known as PAPR<\/a> (powered air purification respirator unit) like in the image below.<\/p>\n\n\n\n AWS provides additional tips, including wearing a welding helmet and safety glasses with UV protective side shields. The organisation also advises the use of a screen, curtains or adequate distance to avoid exposing other workers to radiation, and having anyone near the welding or cutting area wear safety glasses with UV protective side shields.

Explosive atmospheres can be caused by flammable gases, mists or vapours or by combustible dusts. If there is enough of a substance, mixed with air, then all it needs is a source of ignition to cause an explosion.<\/p>\n\n\n\n
Most fires are preventable, dealing with workplace process fire safety is important and those responsible for workplaces and other non domestic premises to which the public have access can avoid them by taking responsibility for and adopting fire safe behaviours and procedures.<\/p>\n\n\n\nElectrical Hazards<\/h3>\n\n\n\n

Symptoms may include mild pressure to intense pain in the eyes, bloodshot eyes, eye irritation (a feeling like sand in the eye, according to CCOHS) and sensitivity to light. Employers must ensure welders wear helmets with the proper shade of filter plate.<\/p>\n\n\n\nWelding Fume Hazards<\/h3>\n\n\n\n
