Immediately call a POISON CENTER or doctor/physician. Ingestion: Rinse mouth. Do NOT induce vomiting. Immediately call a POISON CENTER or doctor/physician. Most Important Symptoms and Effects Both Acute and Delayed
General: Causes severe skin burns and eye damage. Effects of exposure (inhalation, ingestion or skin contact) to
substance may be delayed. Inhalation: Inhalation may cause immediate severe irritation progressing quickly to chemical burns. May cause
pulmonary edema. Skin Contact: Causes severe irritation which will progress to chemical burns. May be absorbed causing redness, pain,
yellow staining. Eye Contact: Causes serious eye damage. Causes permanent damage to the cornea, iris, or conjunctiva. Ingestion: Contact may cause immediate severe irritation progressing quickly to chemical burns. Ingestion is likely to be
harmful or have adverse effects. Chronic Symptoms: May cause erosion of the teeth, or chronic bronchitis.

ter courses. Do not breathe fumes from fires or vapors from decomposition. Protection During Firefighting: Do not enter fire area without proper protective equipment, including respiratory
protection. Hazardous Combustion Products: Nitrogen oxides. Acrid vapors. Reference to Other Sections: Refer to section 9 for flammability properties.

SECTION 6 - ACCIDENTAL RELEASE MEASURES
Personal Precautions, Protective Equipment and Emergency Procedures
General Measures: DO NOT breathe (vapor, mist, spray, gas). Stay upwind of any liquid or vapors. Avoid all contact with

e immediate severe irritation progressing quickly to chemical burns. Ingestion is likely to be
harmful or have adverse effects. Chronic Symptoms: May cause erosion of the teeth, or chronic bronchitis. Indication of Any Immediate Medical Attention and Special Treatment Needed
If exposed or concerned, get medical advice and attention.

SECTION 5 - FIRE-FIGHTING MEASURES
Extinguishing Media
Suitable Extinguishing Media: Dry powder, alcohol-resistant foam, water in large amounts, carbon dioxide (CO2). Unsuitable Extinguishing Media: Do not use a heavy water stream. Use of heavy stream of water may spread fire. Special Hazards Arising from the Substance or Mixture
Fire Hazard: May intensify fire; oxidizer. Will burn if exposed to heat, and in addition, will accelerate the burning of other
combustibles, resulting in more rapid spread of fire. Explosion Hazard: Heat may build pressure, rupturing closed containers, spreading fire and increasing risk of burns and
injuries. Reactivity: Can react explosively with reducing agents, metal powders, hydrogen sulfide, nitrate, and organic materials. Exothermic reaction on contact with water. Advice for Firefighters
Precautionary Measures Fire: Exercise caution when fighting any chemical fire. Firefighting Instructions: Fight fire remotely due to the risk of explosion. Use water spray or fog for cooling exposed
containers. Apply water from as far away as possible and avoid directing water into the acid. Do not allow run-off from
firefighting to enter drains or water courses. Do not breathe fumes from fires or vapors from decomposition. Protection During Firefighting: Do not enter fire area without proper protective equipment, including respiratory
protection.

Materials for Protective Clothing: Acid resistant materials and fabrics.
Hand Protection: Wear acid resistant protective gloves. Neoprene or PVC gloves are required.
Eye Protection: Acid proof goggles and face shield should be required where acid is transferred, sampled, or where
persons are otherwise potentially exposed. Eye baths should be provided when direct contact is possible.
Skin and Body Protection: Wear suitable protective clothing. Where spill or splash potential exists, rubberized aprons or
