INHALATION:
May be irritating to nose and throat. Avoid breathing dust or vapors.
CHRONIC:
There are no known chronic hazards.
ROUTES OF ENTRY:
Skin Contact, Inhalation, Ingestion, Eye Contact.
4. FIRST AID MEASURES
EYES:
If contact with eyes occurs: Immediately flush with cold water for at least 15 minutes. Then get
immediate medical attention.
SKIN:
If contact with skin: Rinse off excess chemical and flush skin with cold water for at least 15
minutes. If skin irritation develops, seek immediate medical attention.
INGESTION:
If swallowed: Drink large amounts of water. Do not induce vomiting. Avoid alcohol. NEVER
GIVE ANYTHING BY MOUTH TO AN UNCONSCIOUS PERSON. Call a physician or poison
control center immediately.
INHALATION:
If inhaled: Remove to fresh air. If breathing is difficult, have trained person administer oxygen.
If not breathing, give artificial respiration. Call a physician immediately.
NOTES TO PHYSICIAN:
Eyes: Natural watering of eyes will dissolve sodium bisulfate, forming a weak sulfuric acid so-
lution which may cause burns. Flush affected area thoroughly with water. Do not use chemical
antidotes or neutralizing solutions.
Skin: Mild burns may occur if not thoroughly flushed previously.
Inhalation: Mild burning sensations may occur to mucous membranes and upper respiratory
tract.
Ingestion: Body water content will react with sodium bisulfate to form a weak sulfuric acid so-
lution, which may burn tissues in mouth, esophagus or stomach. Solution should be diluted to
reduce burning effect.
