Be Prepared: Five Potential Welding Safety Hazards to Avoid by John Petkovsek, Director, Environment, Health and Safety, The Lincoln Electric Company Safety is a critical consideration for any welding project.
The steel base metal gets red hot on occasion locally (right at the grinding or cutting wheel) meaning it is 1600-1800 °F. Zinc melts at about 790 °F and boils to vapor at about 1650 °F. Therefore zinc oxide vapor can absolutely be created by grinding galvanized steel without "melting" the base metal in a welding operation or otherwise.
The difference between welding galvanized steel and welding uncoated steel is a result of the low vaporization temperature of the zinc coating. Zinc melts at about 900˚F and vaporizes at about 1650˚F.
Jan 02, 2014· Non-alloy steel typically doesn't cause much of a problem. Proper practice is, as stated above, a vacuum system that pulls the weld plume up through some ducts through a filter. Or a downdraft table, connected to the same pipes.
The grinding wheel is a cutting tool. It's an abrasive cutting tool. In a grinding wheel, the abrasive performs the same function as the teeth in a saw. But unlike a saw, which has teeth only on its edge, the grinding wheel has abrasive grains distributed throughout the wheel. Thousands of these ...

Aug 10, 2009· When I grind (HSS, Carbon steel, Carbide, etc), I can not miss the little warning labels: 'use dust collection, grinding dust is toxic'. My understanding is that particles (metal, or grinding abrasives) lodge in the lung (like asbestos), and cause problems.
Hexavalent chromium [Cr(VI)] is one of the valence states (+6) of the element chromium. It is usually produced by an industrial process. Cr(VI) is known to cause cancer. In addition, it targets the respiratory system, kidneys, liver, skin and eyes. Chromium metal is added to alloy steel to increase ...
high-temperature processes performed on stainless steel, such as welding and grinding, can cause Cr VI to form a discussion over on ECF led to the conclusion that the more you oxidize stainless steel (i.e. the hotter it gets during torching), the more Cr VI that can be detected
assessment of the hazards associated with metallic stainless steel and those substances which occur during the manufacture and the processing of stainless steel. Currently, stainless steels are classified in the European Union according to the

Welders and grinders face toxic metal, noise hazards at Springfield, Missouri, plant Storage tank manufacturer ignores toxic exposure rules, faces $74K in fines SPRINGFIELD, Mo. - A storage tank manufacturer exposed workers to hazardous levels of hexavalent chromium and potentially deafening noise as they welded and grinded stainless steel and other alloy steels.
Welding stainless steel is just as bad as asbestos? ... Literally millions of hours are spent welding, cutting, grinding, and casting chromium compounds every year. Has there been an exponential increase in chrome related cancers? ... Next check your lifestyle and diet. Maybe occupational hazards.Then throw the dice.
Grinding Steel without a Mask (self.metalworking) submitted 4 years ago by metalsrus Yesterday night I spent about two or so hours grinding down steel plates into, well, smaller steel plates as the supplier had provided incorrect sizes, and we needed they by that day to complete a project.

Nov 29, 2007· The victim recommended that the manufacturer of the grinding wheel should include a very strong warning about the dangers posed by grinding steel after having ground aluminum. That warning should include precautions to thoroughly clean the grinding machine of all aluminum dust before grinding iron or steel.
A. Aluminum powder or grinding swarf is potentially dangerous if it is mixed with iron or steel grinding wastes and is wet. These are the basic ingredients of a thermite bomb, and there is a very real risk of a fire due to the reaction between the aluminum and the iron.
Abstract. OBJECTIVE: To study cause specific mortality and cancer morbidity in workers exposed to the dust of grinding materials, grinding agents, and stainless steel, especially with regard to a possibly increased risk of respiratory, stomach, and colorectal cancer.
Although breathing aluminium dust is not advisable for health reasons, there are much greater dangers associated with sanding, cutting, grinding, deburring and finishing of aluminium parts. The most serious risk arises when aluminium and steel (or stainless steel parts) are worked on in the same area.

Galvanized steel, which is treated with zinc to prevent rust, is useful for tools, equipment, structures, buildings and outdoor items. The material can also be hazardous to your health when you are cutting it, whether you are using a welding machine, drill, engraver or other cutting tools.
Machining. Machining processes include milling, turning, drilling, and threading. Stainless steels are generally more challenging to machine than standard carbon steel and a general rule is that the higher a steel's alloying content, the more difficult it is to machine.
