Welding Fumes and Gases Safety 121

The class Welding Fumes and Gases Safety helps students to understand the dangers of fume and gas generation in welding. The fume plume, a visible cloud of smoke rising from the molten metal, consists of complex metallic oxides and particles formed from the consumable and base metal. Shielding gases used in welding may also produce potentially harmful fumes. Exposure to fumes can be managed through engineering controls, ventilation, proper PPE, and adherence to exposure limits set by OSHA or other organizations. After taking this class, the student will understand the potential dangers of welding fumes and gases, as well as the acute and chronic symptoms that may develop after overexposure. This class discusses how workplace practices and engineering controls can be used to control exposure, in addition to following Permissible Exposure Limits and using air-supplied respirators when necessary.
