ASTHMA OR OTHER PULMONARY DISEASES.

First Aid:INHALATION: REMOVE TO FRESH AIR. IF BREATHING HAS STOPPED OR
PATIENT EXPERIENCES DIFFICULTY IN BREATHING, ADMINISTER ARTIFICIAL
RESPIRATION. GET IMMEDIATE MEDICAL ATTENTION FOR EXPOSURE TO SULFUR
DIOX IDE GAS. EYES:IMMEDIATELY REMOVE CONTACT LENSES & GENTLY FLUSH
THE EYES & SUR-ROUNDING AREAS WITH LUKEWARM WATER FOR 15 MINUTES.
IF IRRITATION PERSISTS, SEEK MEDICAL ATTENTION. SKIN: REMOVE
CONTMINAT ED CLOTHING. WIPE MATERIAL FROM THE SKIN. RINSE THE
AFFECTED AREA WITH LARGE AMOUNTS OF WATER FOR 15 MINUTES.
