GASES and FUMES can be dangerous.

When welding with electrodes which require special ventilation such as stainless or
hard facing or on lead or cadmium plated steel and other metals or coatings which
produce highly toxic fumes, keep exposure as low as possible and keep the
exposure level under Minimum Limit Values using local exhaust or mechanical
ventilation. In confined spaces or in some circumstances, a respirator may be
required even outdoors. Additional precautions are also required when welding on
galvanized steel.
Do not weld in locations near chlorinated hydrocarbon vapors coming from
degreasing, cleaning or spraying operations. The heat and rays of the arc can react
with solvent vapors to form a highly toxic gas, and other irritating products.
Welding may cause fumes and gases that are injurious to health. Always enough
ventilation should be used or fumes and gases should be exhausted from breathing
place.
Generally in welding applications temporary effects for short time can be seen such
as face and skin burning, dizziness, nausea and fever based on exposure period
and amount of fume. Long time fume exposure may cause iron loading and
dysfunctions in lungs. Bronchitis and pulmonary fibrosis are primary effects occurred.
Some electrodes may include alloys that entail special ventilation. Label of these
products that entails special ventilation should not be ignored and Product Safety
Information Form reports should be read carefully. When welding on this kind of
materials it may be necessary to use gas mask.
Keeping your head out of fume clouds is the easiest way for protection against toxic
fumes and gases.

Avoid breathing these fumes and gases, air circulation or mechanical ventilation
equipments should be used and if the ventilation is not enough gas mask should be
used.
