Toxic Results Of Argon Base Welding

The leading danger associated with argon-based welding is asphyxiation, a hazard typical to shielding gases. Loss of consciousness can arise within seconds when there are Exorbitant levels of argon in the surrounding air.


Use


Shielding gases analogous argon, an inert Gauze, are used to protect a metal joint from contamination during welding. Convulsions, coma, and death can occur quickly. The oxygen levels in the workplace should be maintained at levels of at least 18 percent, according to "What are the hazards from gases during welding and cutting?" by Graham Carter, writing for TWI, a UK-based research organization.



If argon leaks into the air from faulty lines and concentrations in the air rise to 50 percent, a welder starts to breathe more quickly. There is a loss of alertness, muscle coordination and energy.


Advanced Symptoms


As asphyxiation progresses, a welder can become dizzy, nauseous, start to vomit and lose consciousness. Argon is heavier than air and settles in lower areas, thus acting to shield the joint from particles in the air.

Early Symptoms

The tendency of argon to settle also decreases the amount of oxygen present in the air.
