SECTION 4. FIRST-AID MEASURES
Description of first aid measures
Ingestion : Do NOT induce vomiting. Have victim rinse mouth with water, then give one to two
glasses of water to drink. Never give anything by mouth to an unconscious person.
Call a physician.
Inhalation : If inhaled, move to fresh air. If breathing is difficult, give oxygen by qualified medical
personnel only. If breathing has stopped, give artificial respiration. Obtain medical
attention if symptoms develop and persist.
Skin contact : Wash off immediately with plenty of water. Remove and wash contaminated clothing
before re-use. If irritation or symptoms develop, seek medical attention.
Eye contact : Immediately flush eyes with running water for at least 5 to 10 minutes. If irritation
persists, seek prompt medical attention.
Most important symptoms and effects, both acute and delayed
: Causes eye irritation. Symptoms may include tearing, redness and discomfort. Direct
skin contact may cause slight or mild, transient irritation. Ingestion may cause
gastrointestinal irritation, nausea, vomiting and diarrhea.
Indication of any immediate medical attention and special treatment needed
: Treat symptomatically.

SECTION 5. FIRE-FIGHTING MEASURES

Extinguishing media
Suitable extinguishing media
: Use media suitable to the surrounding fire such as water fog or fine spray, alcohol
foams, carbon dioxide and dry chemical.
Unsuitable extinguishing media
: Do not use a solid water stream as it may scatter and spread fire.
Special hazards arising from the substance or mixture / Conditions of flammability
: Burning may produce irritating, toxic and obnoxious fumes.
Flammability classification (OSHA 29 CFR 1910.106)
: Not flammable.
Hazardous combustion products
: Carbon oxides; .
Special protective equipment and precautions for firefighters
Protective equipment for fire-fighters

SAFETY DATA SHEET

: Firefighters should wear proper protective equipment and self-contained breathing

apparatus with full face piece operated in positive pressure mode. Move containers
from fire area if safe to do so. Water spray may be useful in cooling equipment
exposed to heat and flame.
SECTION 6. ACCIDENTAL RELEASE MEASURES
Personal precautions, protective equipment and emergency procedures
: Restrict access to area until completion of clean-up. Ensure clean-up is conducted by
trained personnel only. Wear suitable protective equipment. Refer to protective
measures listed in sections 7 and 8. Restrict access to area until completion of
clean-up.
Environmental precautions : Ensure spilled product does not enter drains, sewers, waterways, or confined spaces.
Methods and material for containment and cleaning up
: Ventilate area of release. Stop spill or leak at source if safely possible. Dike for water
control. Contain and absorb spilled liquid with non-combustible, inert absorbent
material (e.g. sand), then place absorbent material into a container for later disposal
(see Section 13).
Special spill response procedures
: In case of transportation accident, contact TERRAPURE ENVIRONMENTAL at
1-800-567-7455.
SECTION 7. HANDLING AND STORAGE
Precautions for safe handling
: Use only in well-ventilated areas. Wear suitable protective equipment during handling.
Avoid breathing vapours or mists. Avoid contact with eyes, skin and clothing. Keep
away from extreme heat and flame. Keep away from incompatibles. Keep containers
tightly closed when not in use. Wash thoroughly after handling.
Conditions for safe storage : Storage area should be clearly identified, clear of obstruction and accessible only to
trained and authorized personnel. Store away from incompatible materials.No smoking
in the area.
Incompatible materials : Strong oxidizers (e.g. Chlorine, Peroxides, etc.).; Strong acids ;Strong alkalis .
