Health Hazards Acute and Chronic:FUMES/GASES CAN BE DANGEROUS TO YOUR
HLTH. PRIMARY ROUTE OF EXPOS IS INHAL OF FUMES. ACUTE: OVEREXPOS TO
WELDING FUMES MAY RSLT IN DISCOMFORT SUCH AS DIZZ, NAUS &
DRYNESS/IRRIT OF NOSE, THROAT OR EYES . CHRONIC:OVEREXPOS MAY LEAD
TO SIDEROSIS (IRON DEPOSITS IN LUNGS) & IS BELIEVED BY SOME
INVESTIGATORS (EFTS OF OVEREXP)
