IN DISCOMFORT, DIZZINESS, NAUSEA AND DRYNESS OR ITTITATION OF THE
THROAT. LONG TERM EXPOSURE TO WELDING FUMES, GASES OR DUST MAY
CONTRIBUTE TO PULMONARY IRRITATION OR PNEUMONOCONIOSIS. LONG TERM
EXPOSURE TO IRON FUMES MAY PRODUCE SIDEROSIS, WHICH IS REGARDED AS
BENIGN.
Medical Cond Aggravated by Exposure:INDIVIDUALS WITH IMPAIRED PULMONARY
FUNCTIONS OR ILLNESS MAY HAVE SYMPTOMS EXCERBATED BY IRRITANTS
