SECTION 2 – Hazards Identification
EMERGENCY OVERVIEW
Appearance: Clear. DANGER! Corrosive. Causes eye and skin burns. May cause respiratory tract
irritation with possible burns. May cause severe digestive tract irritation with burns.
TARGET ORGANS: No Data Found.
POTENTIAL HEALTH EFFECTS
EYE: Causes eye burns. May cause chemical conjunctivitis and corneal damage.
SKIN: Causes skin burns. May cause deep, penetrating ulcers of the skin. May cause skin rash (in
milder cases), and cold clammy skin with cyanosis or pale color.
INGESTION: May cause severe and permanent damage to the digestive tract. Causes
gastrointestinal tract burns. May cause perforation of the digestive tract. Causes severe pain,
nausea, vomiting, diarrhea, and shock. May cause systemic events.
Inhalation: Irritation may lead to pneumonitis and pulmonary edema. Causes severe irritation of

upper respiratory tract with coughing, burns, breathing difficulty, and possible coma. Causes
chemical burns to the respiratory tract. Aspiration may lead to pulmonary edema. May cause
systemic effects.
CHRONIC: Prolonged or repeated skin contact may cause dermatitis. Effects may be delayed.
SECTION 4 – First Aid Measures
EYES: Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed. Extensive
irrigation 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. Wash clothing before reuse. Discard
contaminated clothing in a manner which limits further exposure.
INGESTION: Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cups 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 not
breathing, give artificial respiration. If breathing is difficult, give oxygen. DO NOT use mouth-to-mouth
respiration. If breathing has ceased apply artificial respiration using oxygen and a suitable
mechanical device such as a bag or mask.
NOTES TO PHYSICIAN: Treat symptomatically and supportively.
SECTION 5 – Firefighting 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. Use water spray to
keep fire exposed containers cool. Use water with caution in flooding amounts. Vapors may be
heavier than air. They can spread along the ground and collect in low or confined areas. Contact
with metals may evolve flammable hydrogen gas. Containers may explode when heated. Non-
combustible, substance itself does not burn but may decompose upon heating to produce irritating,
corrosive and/or toxic fumes.
EXTINGUISHING MEDIA: Do NOT get water inside containers. For small fires, use dry chemical,
carbon dioxide, or water spray. For large fires, use dry chemical, carbon dioxide, alcohol-resistant
foam, or water spray. Cool containers with flooding quantities of water until well after the fire is out.
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., dry sand or earth), then place into a chemical
waste container. Avoid runoff into storm sewers and ditches that lead to waterways. Clean up spills
immediately, observing precautions in the Protective Equipment section. Provide ventilation.
SECTION 7 – Handling and Storage
Handling: Wash thoroughly after handling. Use only in a well-ventilated area. Do not breathe dust,
vapor, mist or gas. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Do not
ingest or inhale. Discard contaminated shoes.
STORAGE: Keep container tightly closed when not in use. Store in a cool, dry, well-ventilated area
away from incompatible substances. Keep away from strong acids. Keep away from metals. Keep
away from flammable liquids. Keep away form organic halogens.
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 adequate ventilation to keep airborne concentrations low.
