Welding Exhaust Ventilation. 2 welders head position. The fume exhaust given off by the process of welding can take a damaging toll on the inner body.
The inhalation of welding exhaust fumes such as manganese and hexavalent chromium can harm a persons eyes lungs and brain. It contains or refers to information on air contaminants found in the welding fumes principles of systems design and selection and drawings that illustrate ventilation techniques. Although ventilation is generally considered the most effective control method during welding12 research shows that various factors such as.
The fume generation rate.
Welding cutting or heating in any enclosed spaces involving the metals specified in this subparagraph shall be performed with local exhaust ventilation in accordance with the requirements of paragraph a of this section or employees shall be protected by air line respirators in accordance with the requirements of Subpart E of this part. Reducing the exposure to fumes through an effective local exhaust or area ventilation system is the first line of defense in preventing discomfort or illnesses from toxic welding fumes. These are source capture exhaust systems with a cartridge dust collector and exhaust fan located remotely ducted to slotted hoods backdraft hoods or fume extraction arms positioned at each weld station or point. All affect the ability of the LEV to control the fumes and should incorporated into the control strategies101114.
