When welding on metal materials, zinc oxide and other fumes can get in the face of the welder and cause health issues, like metal fume fever. How do you prevent these health effects and provide clean air for the welder to breathe? Respiratory protection is often the first thought. However, engineering controls, such as adequate ventilation, can prevent the need to wear yet another piece of protective gear while welding.
What are the common types of ventilation used in a workplace? Dilution ventilation is the use of clean air to decrease the concentration of a contaminant of concern.
