Health and Safety in Welding and Allied Processes

From: Employment and Social Development Canada. Request other formats online or call 1 O-Canada If you use a teletypewriter TTY , call This guideline provides a summary of the health effects associated with welding processes and the control measures that should be employed at the work place. Welding, for the purposes of this guideline, is the industrial process for making welds to join metals. Allied processes also involve metals and are somewhat similar with respect to the hazards created, they include gouging, cutting or grinding metal or otherwise preparing or finishing it.

Scope and Applicability This policy applies to all employees, students, faculty and contractors who may perform welding, cutting, or brazing in their job functions. Definitions Brazing: Applies heat to the metal, usually from an oxy-acetylene gas flame. The metal does not reach its melting point. Instead, filler material and flux from a welding rod melt to form the weld. Fire Watch: Trained personnel who are in attendance during the entire cutting and welding operation and are immediately available to extinguish a fire or take other effective action if necessary. Gas Cutting: Creates a molten pool of metal using heat from a gas torch. A jet of oxygen is injected into the pool to accelerate the oxidation of the material.

Part 1 Risks and their control: Setting up the workplace; First aid and accident reporting; Fire; Compressed and liquefied gases; Fume, dust, vapour and gases; Control of exposure to fume, dust, vapour, gases; Radiation; Noise and vibration; Mechanical hazards. Part 2 Processes: Gas welding, cutting and preheating; Arc welding and cutting; Plasma arc processes; Electroslag welding; Resistance welding; Thermit welding; Electron beam welding; Friction welding; Laser welding and cutting; Brazing and braze welding; Soft soldering; Thermal spraying; Welding and flame spraying plastics; Inspection and testing; Welding in more hazardous environments. Part 3 Legislation and appendices. This edition of Health and safety in welding and allied processes has been extensively revised to take into recent account advances in technology and legislative changes both in the UK and USA. Beginning with a description of the core safety requirements, it goes on to describe the special hazards found in the welding environment — noise, radiation, fume, gases and so on in terms of their effects and the strategies that can be adopted to avoid them. The book takes each major joining technology in turn and discusses the key hazards that are most relevant to each process. There are chapters covering: the common arc and gas welding processes; specialised welding processes; brazing, soldering and thermal spraying; welding and flame spraying of plastics; radiographic inspection; mechanical hazards; noise and vibration; radiation; compressed gases; fume and ventilation; fire and first aid; and welding in situations of increased hazard, such as those requiring special precautions to ensure safe working on vessels contaminated by flammable materials.

Arc welding is a safe occupation when sufficient measures are taken to protect the welder from potential hazards. When these measures are overlooked, welders can encounter such dangers as electric shock, overexposure to fumes and gases, arc radiation, and fire and explosion. Keeping the arc welding operator in mind, here you will find both mandatory safety practices and those based on shop experience. Welding Safety Downloads. Arc Welding Safety.

This article presents an overview of the rules, regulations, and techniques implemented to minimize the safety hazards associated with welding, cutting, and allied processes. Safety management, protection of the work area, process-specific safety considerations, and robotic and electrical safety are discussed. The article explains the use of personal protective equipment and provides information on protection against fumes, gases, and electromagnetic radiation. It concludes with a discussion on safe handling of compressed gases as well as the prevention and protection of fire and explosion. Lienert, T. Siewert, S.


In mid, it was recognized that some type of code or standard was needed relating to safe practices for performing welding. Under the auspices of the American Standards Association, the standard was drafted and published in

 Вторжение по всем секторам. Сьюзан двигалась как во сне. Подойдя к компьютеру Джаббы, она подняла глаза и увидела своего любимого человека.

Сигнальная лампочка вспыхнула, и массивная стена с грохотом отъехала влево. В АНБ было только одно помещение, еще более засекреченное, чем шифровалка, и Сьюзан поняла, что сейчас она окажется в святая святых агентства.

И если он проникнет в главную базу данных… - Что еще за файл, черт возьми. Покажите мне. Чатрукьян заколебался. - Я не могу. - Разумеется, не можете. Его же не существует. - Коммандер, я должна… - попробовала вставить слово Сьюзан.

Стратмор покачал головой. - Я попросил его не звонить мне, пока он не найдет кольцо. - Почему? - удивилась Сьюзан.  - А если ему нужна помощь. Стратмор пожал плечами. - Отсюда я не в состоянии ему помочь - ему придется полагаться лишь на .

Молодой священник, причащавший Беккера, смотрел на него с неодобрением. Ему было понятно нетерпение иностранца, но все-таки зачем рваться без очереди. Беккер наклонил голову и тщательно разжевывал облатку. Он почувствовал, что сзади что-то произошло, возникло какое-то замешательство, и подумал о человеке, у которого купил пиджак. Беккер надеялся, что тот внял его совету не надевать пока пиджак. Он начал было вертеть головой, но испугался, что очки в тонкой металлической оправе только этого и ждут, и весь сжался, надеясь, что черный пиджак хоть как-то прикроет его брюки защитного цвета.

Он бросил взгляд на истончающиеся защитные щиты. - Агент Смит, - произнес он медленно и четко, - мне нужен предмет. Лицо у Смита было растерянным.
