Reduce exposure to welding fume hazards

Welding processes are classified into two groups: fusion welding, which is heat alone, and pressure welding, which uses heat and pressure. Fusion welding involves three types: electric arc, gas and thermit.

All of these forms of welding produce visible smoke that contains harmful metal fume and gas byproducts, OSHA states. Welding fumes contain a variety of metals, including aluminum, arsenic, beryllium, lead and manganese. Argon, nitrogen, carbon dioxide, carbon monoxide and hydrogen fluoride gases often are produced during welding.

Health issues

Welding fumes can cause serious health problems for workers if inhaled, according to OSHA. Short-term exposure can result in nausea, dizziness, or eye, nose and throat irritation. Prolonged exposure to welding fumes can lead to cancer of the lung, larynx and urinary tract, as well as nervous system and kidney damage. Certain gases, such as helium, carbon dioxide and argon, displace oxygen and can pose suffocation risks, OSHA notes, particularly in enclosed work areas.

OSHA offers tips to help welders reduce their exposure level to welding fumes and gases. Among them:
