Beta This is a new way of showing guidance - your feedback will help us improve it. If welding is part of your work activity, you must carry out a risk assessment to identify what measures are required to control the risks from exposure to welding fume. Without controls in place, workers will be exposed to welding fume.
Mitigating Welding Hazards
Welding work brings hazards. Avoiding them requires training, expertise, skill and mindfulness from employers and workers — along with a systematic approach to safety. Here are some of the major hazards workers may encounter when welding and how to protect against them. Workers must move any combustible materials at least 35 feet away from where welding and other hot work will occur. The foot boundary can increase based on worksite conditions, especially when outdoors or working at elevation. The NFPA standard provides an illustration. The standard also details the duties of a particular, important member of a hot work team: the fire watch.
Welding - Overview of Types and Hazards
Download this information as a pdf ideal for printing and sharing. In support of the Breathe freely campaign Oxford Academic have developed a collection which brings together key papers addressing respiratory hazards and welding, and methods for their control. Freely access these articles until 31 May There are many different measures that can be implemented to control exposure to hazardous substances. Those measures towards the top of the hierarchy are normally considered to be most preferable. In principle, anyone considering control 2 techniques should start at the top of the list, considering each option in turn and deciding whether it is feasible.

Welding is a joining process in which metals, or sometimes plastics, are heated, melted and mixed to produce a joint with properties similar to those of the materials being joined. There are over 70 different welding processes. The type of welding process used is related to the specific application.
Welding operations present several hazards to both those undertaking the activity and others in the vicinity. During the arc welding process, live electrical circuits are used to create a pool of molten metal. Therefore, when welding, you are at risk of experiencing an electric shock. These include welding:. When carrying out welding activities, you are likely to be exposed to loud, prolonged noises.
Welding Hazards in the Workplace: Safety Tips & Precautions
Welding has a number of hazards associated with it that include heat, fumes, flying debris, harmful dust, and even ultraviolet and infrared radiation. Without proper protective gear and procedures, the probability of injury skyrockets. And the toxicity of the welding substances that are found in the smoke depends on what materials are being welded.
Properly installed and used the arc welder is very safe, but if used improperly the operator can be exposed to a number of hazards including toxic fumes, dusts, burns, fires, explosions, electric shock, radiation, noise, and heat stress.
Follow the hazards control hierarchy to reduce welding risks
Several potential health and safety problems associated with welding are noted in this pamphlet. These problems vary with the method of welding, location of work, materials being welded, and the instituted control measures. Certain hazards are common to most welding processes. These include damage to the eyes and skin from infrared and ultraviolet radiation, burns from contact with hot metal or sparks, adverse physiological effects from breathing metal fumes and gases, accidents from material handling, and shock from electrical current. Welding hazards are controlled by employing proper ventilation principles, using respirators and other personal protective devices including proper clothing and by following safe working practices in general.
Их надо использовать с толком. Фонтейн долго молчал. Потом, тяжело вздохнув, скомандовал: - Хорошо.
Эта машина помогла предотвратить десятки преступлений, но связанная с ней информация строго засекречена и никогда не будет раскрыта. Причина такой секретности проста: правительство не может допустить массовой истерии. Никто не знает, как поведет себя общество, узнав, что группы фундаменталистов дважды за прошлый год угрожали ядерным объектам, расположенным на территории США. Ядерное нападение было, однако, не единственной угрозой. Только в прошлом месяце благодаря ТРАНСТЕКСТУ удалось предотвратить одну из самых изощренных террористических акций, с которыми приходилось сталкиваться агентству.
