Section 3 - Hazards Identification
EMERGENCY OVERVIEW
Appearance: APHA: 10 max - colorless viscous liquid. Danger! Corrosive. May cause severe respiratory tract
irritation with possible burns. May cause severe digestive tract irritation with possible burns. Causes severe eye and
skin irritation and burns. May cause cyanosis (bluish discoloration of skin due to deficient oxygenation of the blood).
Harmful if inhaled. May be harmful if swallowed.
Target Organs: Blood, liver, bone marrow.
Potential Health Effects
Eye: Contact with liquid is corrosive to the eyes and causes severe burns. May cause chemical conjunctivitis and
corneal damage.
Skin: Contact with liquid is corrosive and causes severe burns and ulceration. May cause skin rash (in milder cases),
and cold and clammy skin with cyanosis or pale color.
Ingestion: Causes gastrointestinal tract burns. Causes severe pain, nausea, vomiting, diarrhea, and shock. May
cause hemorrhaging of the digestive tract. May cause corrosion and permanent tissue destruction of the esophagus
and digestive tract. May be harmful if swallowed. May form methemoglobin which in sufficient concentration causes
cyanosis (bluish discoloration of skin due to deficient oxygenation of the blood).
Inhalation: Harmful if inhaled. May cause severe irritation of the respiratory tract with sore throat, coughing,
shortness of breath and delayed lung edema. Causes chemical burns to the respiratory tract. Aspiration may lead to
pulmonary edema.
Chronic: Prolonged or repeated skin contact may cause dermatitis. Prolonged or repeated eye contact may cause
conjunctivitis. Effects may be delayed. Chronic exposure may cause liver damage. May cause cyanosis - a blue-gray
coloring of the skin and lips caused by a lack of oxygen. Inhalation of vapors at high concentrations may produce

pulmonary edema characterized by fluid build-up in the lungs.
Section 4 - First Aid Measures
Eyes: Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed. Extensive irrigation with water is
required (at least 30 minutes).
Skin: Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes
while removing contaminated clothing and shoes. Discard contaminated clothing in a manner which limits further
exposure. Destroy contaminated shoes.
Ingestion: Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give
anything by mouth to an unconscious person. Get medical aid immediately.
Inhalation: Get medical aid immediately. Remove from exposure to fresh air immediately. If breathing is difficult,
give oxygen. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased apply artificial respiration using
oxygen and a suitable mechanical device such as a bag and a mask.
Notes to Physician: Persons with pre-existing skin disorders or impaired respiratory or pulmonary function may be
at increased risk to the effects of this substance. Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH
(approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated
by thermal decomposition or combustion. Vapors may be heavier than air. They can spread along the ground and
collect in low or confined areas.
Extinguishing Media: Use extinguishing media most appropriate for the surrounding fire. Cool containers with
flooding quantities of water until well after fire is out. Use water spray, dry chemical, carbon dioxide, or appropriate
foam.
Section 6 - Accidental Release Measures
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container.
Clean up spills immediately, observing precautions in the Protective Equipment section. Provide ventilation.
Section 7 - Handling and Storage
Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Keep container
tightly closed. Do not get on skin or in eyes. Do not ingest or inhale. Use with adequate ventilation. Use only in a
chemical fume hood. Discard contaminated shoes.
Storage: Keep container closed when not in use. Store in a tightly closed container. Store in a cool, dry, well-
ventilated area away from incompatible substances. Keep away from metals. Do not store in metal containers. Store
away from alkalies.
Section 8 - Exposure Controls, Personal Protection
Engineering Controls: Facilities storing or utilizing this material should be equipped with an eyewash facility and a
safety shower. Use only under a chemical fume hood.

Environmental: The acidity of phosphoric acid may be reduced readily by natural water hardness minerals, but the
phosphate may persist indefinitely. During transport through the soil, phosphoric acid will dissolve some of the soil
material, in particular, carbonate-based materials. The acid will be neutralized to some degree with adsorption of the
proton and phosphate ions also possible. However, significant amounts of acid will remain for transport down toward
the groundwater table.
Physical: No information available.
Other: Dangerous to aquatic life in high concentrations.
Section 13 - Disposal Considerations
Chemical waste generators must determine whether a discarded chemical is classified as a hazardous waste. US EPA
guidelines for the classification determination are listed in 40 CFR Parts 261.3. Additionally, waste generators must
consult state and local hazardous waste regulations to ensure complete and accurate classification.
