One of the most significant health hazards in the welding process is the
generation of fumes and gasses. Do you weld on galvanized metals? Zinc is the
coating used on galvanized metals, and when you heat the metal, it produces
vaporized metal droplets which are called fumes. This is the smoky haze which
consists of fine particles of metals or silicates. When you breathe these fumes,
they may work deeply into your lungs.
The typical effect of breathing zinc fumes is metal fume fever. One or two
hours or more after welding-without proper personal protection-you may
experience severe thirst, pain in the legs, shivering, congestion in the head,
dryness and tickling of the throat, and a cough. In very bad cases, you may feel
severe shivering, a high fever, buzzing in the ears, nausea, vomiting, and even
hallucinations and convulsions. Your symptoms will usually last 24 hours.
Some of you may weld for a period of time and find some of the symptoms
appeared, then went away. You may actually have built up an immunity that hides
the full effects. If you take a break from welding over the weekend or over a
holiday, the symptoms will often come back again the next time you weld on
galvanized metal. Because of this behavior, metal fume fever is sometimes known
as "Monday morning sickness."
Protect yourself, if you weld on galvanized metals, by following these precautions:
Finally, did you know that you can "contaminate" your family by bringing home zinc particles on your clothing? Protect both yourself and your family-weld safely.
