ISO 9000 was first published in 1987 by ISO (International Organization for Standardization). It was based on the BS 5750 series of standards from BSI that were proposed to ISO in 1979. However, its history can be traced back some twenty years before that, to the publication of the United States Department of Defense MIL-Q-9858 standard in 1959. MIL-Q-9858 was revised into the NATO AQAP series of standards in 1969, which in turn were revised into the BS 5179 series of guidance standards published in 1974, and finally revised into the BS 5750 series of requirements standards in 1979 before […]
Work in confined spaces requires consideration of: Ventilation Securing cylinders and machinery Lifelines Electrode removal (arc welding) Gas cylinder shutoff (gas welding & cutting) Warning signs for hot metal
Gas – Slower and easier to control than electric arc. Uses gas flame over metals until molten puddle is formed. Most popular fuels used with oxygen include acetylene, mapp gas, and hydrogen. Arc – Two metals are joined by generating an electric arc between a covered metal electrode and the base metal. Oxygen and Arc Cutting – Metal cutting in welding is the severing or removal of metal by a flame or arc.
