Material Safety Data Sheet
4.2 Most important symptoms and effects, both acute and delayed
See Section 11
4.3. Indication of any immediate medical attention and special treatment needed
Treat symptomatically.
Copper, magnesium, aluminium, antimony, iron, manganese, nickel, zinc (and their compounds) in welding, brazing,
galvanising or smelting operations all give rise to thermally produced particulates of smaller dimension than may be produced
if the metals are divided mechanically. Where insufficient ventilation or respiratory protection is available these particulates
may produce "metal fume fever" in workers from an acute or long term exposure.
Onset occurs in 4-6 hours generally on the evening following exposure. Tolerance develops in workers but may be lost over
the weekend. (Monday Morning Fever)
Pulmonary function tests may indicate reduced lung volumes, small airway obstruction and decreased carbon monoxide
diffusing capacity but these abnormalities resolve after several months.
Although mildly elevated urinary levels of heavy metal may occur they do not correlate with clinical effects. The general
approach to treatment is recognition of the disease, supportive care and prevention of exposure.
Seriously symptomatic patients should receive chest x-rays, have arterial blood gases determined and be observed for the
development of tracheobronchitis and pulmonary edema.
