Proper training, regular inspection of welding equipment, and ensuring worker's . By its nature, welding produces fumes and noise, gives off radiation, involves electricity or gases, and has the potential for burns, shock, fire, and explosions. Gas torch welding and cutting. Note also that this table of examples does not include all possible hazards. The following section briefly describes these potential hazards and discusses some protective measures for the specific hazards. 2.4 Reviewing control measures 8 3. The principal hazards associated with demolition work are: Falls from height or on the same level; Falling debris; The premature collapse of the structure being demolished; Dust and fumes; The silting up of drainage systems by dust; The problems arising from spilt fuel oils; Manual handling; Presence of asbestos and other hazardous substances; Health hazards from welding, cutting, and brazing operations include exposures to metal fumes and to ultraviolet (UV) radiation. involve either a gas flame or an electrically generated arc. Example: Welding fume. To incorporate all the Hazard & appropriated precautionary measures Welding Hazards can be roughly broken into seven risks categories: 1. Middle level (Operator's) 3. There are three types of fusion welding: electric arc, gas and thermit. Keywords: Control Measures, Hazard Identification process, Risk Factors, Welding shops. TIG welding is a method often used for joining of light metals and high-alloy steels and it contains a number of risks as with other arc welding methods. Here's a list of common work at heights hazards: Improper safety measures when raising and dismantling scaffolding. As the metal is heated a fine metal fume is formed, usually with visible smoke. Arc welding is a safe occupation when proper precautions are taken. 1 safety in gas cutting and welding. Where possible, working at height should be avoided, usually by carrying out tasks from the ground. Potential health, safety, and property hazards result from the fumes, gases, sparks, hot metal and radiant energy produced during hot work.
