Section 3 - Hazards Identification
EMERGENCY OVERVIEW
Appearance: clear blue. Danger! Causes skin burns. Causes eye burns. Causes digestive tract
burns. Causes respiratory tract burns. Corrosive.
Target Organs: None.
Potential Health Effects
Eye: Causes severe eye burns.
Skin: Causes skin burns. May cause deep, penetrating ulcers of the skin.
Ingestion: Causes gastrointestinal tract burns. Causes severe pain, nausea, vomiting, diarrhea,
and shock.
Inhalation: Irritation may lead to chemical pneumonitis and pulmonary edema. Causes severe
irritation of upper respiratory tract with coughing, burns, breathing difficulty, and possible coma.
Chronic: Prolonged or repeated skin contact may cause dermatitis. Individuals with Wilson's
disease are unable to metabolize copper. Thus, copper accumulates in various tissues and may
result in liver, kidney, and brain damage. Copper salts may also cause extensive damage to the
kidneys, liver, and capillaries with CNS depression, hemolytic anemia, joint pain, gastric
hemorrhage and joint pain indicating intoxication. Relatively large doses of dry sodium potassium
tartrate (2-4 gm) may have a cathartic effect.
Section 4 - First Aid Measures
Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the
upper and lower lids until chemical is gone. Get medical aid at once. Cover burns with loose
sterile non-medicated bandages.
Skin: Get medical aid at once. Immediately flush skin with plenty of soap and water for at least
15 minutes while removing contaminated clothing and shoes. Remove contaminated clothing and
shoes. Cover burns with a dry sterile bandage (secure, not tight).
Ingestion: Do NOT induce vomiting. Give conscious victim 2-4 cupfuls of milk or water. Never
give anything by mouth to an unconscious person. Get medical aid at once. Medical personnel
may do esophagoscopy, irrigate injured area with 1% acetic acid to neutralize alkali.
Inhalation: Give artificial respiration if necessary. If breathing is difficult, give oxygen. Get
medical aid. Keep victim warm, at rest. Move victim to fresh air.
Notes to Physician: Treat symptomatically and supportively.
Section 5 - Firefighting Measures
General Information: Wear appropriate protective clothing to prevent contact with skin and
eyes. Wear a self-contained breathing apparatus (SCBA) to prevent contact with thermal
decomposition products. Use water with caution and in flooding amounts. Negligible fire and
explosion hazard when exposed to heat or flame.
Extinguishing Media: For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam.
Section 6 - Accidental Release Measures
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Absorb spills with absorbent (vermiculite, sand, fuller's earth) and place in plastic
bags for later disposal. Material may be neutralized to pH 7 with citric acid or other suitable
neutralizing agent.
Section 7 - Handling and Storage
Handling: Wash thoroughly after handling. Use with adequate ventilation. Do not get in eyes, on
skin, or on clothing. Do not ingest or inhale.
Storage: 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
from organic halogens.
Section 8 - Exposure Controls, Personal Protection
Engineering Controls: Use adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits.
