A. EMERGENCY OVERVIEW
Physical Appearance and Odor
Colorless liquid, odorless.
Warning Statements:
DANGER! CAUSES BURNS.
Contact with reactive metals zinc, bare steel may evolve highly flammable hydrogen gas.
Danger of explosion if hydrogen gas evolved in confined area.
B. POTENTIAL HEALTH EFFECTS
Phosphoric acid is corrosive to all parts of the body.
Acute eye:
Corrosive. Causes tissue destruction, permanent damage to the cornea, blindness.
Acute skin:
Causes irritation, burns.
Acute inhalation:
Mists may cause lung irritation, shortness of breath, fluid in lungs.
Acute ingestion:
Can cause corrosion of and damage to the gastro-intestinal tract.
Chronic effects:
Severity of acute effects is such that significant repeated or prolonged exposure is unlikely.
The product does not contain any ingredient designated by IARC, NTP, ACGIH or OSHA as
probable or suspected human carcinogens.
4. First-aid measures
Contaminated individuals must be taken for medical attention if any adverse reaction occurs.
Rescuers should be taken for medical attention, if necessary.
Take a copy of label and MSDS to health professional with contaminated individual.
Hold eyelids open and flush with a steady, gentle stream
of water for at least 15 minutes. Seek immediate medical

Move the injured person to fresh air at once.
Inhalation
Assure that the victim is breathing. If breathing is
difficult, administer oxygen, if available. Seek immediate
medical attention.
Do not induce vomiting.
Ingestion
If victim is conscious and alert, give 2-3 glasses of water
to drink. Seek immediate medical attention.
NOTE: Never give an unconscious person anything to drink.
Treat symptomatically.
Notes to physician:
