SECTION 4. FIRST AID MEASURES

Inhalation: Immediately call a poison center or doctor. Effects of exposure (inhalation) to substance may be delayed.
Inhalation of vapors or contact with substance will result in contamination and potential harmful effects.
Move victim to fresh air. Give artificial respiration if victim is not breathing. Administer oxygen if breathing is
difficult. Keep victim warm and quiet. Treat symptomatically and supportively. Ensure that medical
personnel are aware of the material(s) involved and take precautions to protect themselves.
Skin contact: For severe burns, immediate medical attention is required. Immediately call a poison center or doctor.
Effects of exposure (skin contact) to substance may be delayed. Remove and wash contaminated clothing
before re-use. Remove and isolate contaminated clothing and shoes. In case of contact with substance,
immediately flush skin with running water for at least 20 minutes. Treat symptomatically and supportively.
Ensure that medical personnel are aware of the material(s) involved and take precautions to protect
themselves.
Eye contact: IMMEDIATELY flush eyes with running water for at least 15 minutes, keeping eyelids open. Eye contact
with vapors or substance may cause severe injury, burns, or death. Call emergency medical service. Move
victim to fresh air. Check for and remove any contact lenses. Keep victim warm and quiet. Treat
symptomatically and supportively. Effects of exposure to substance may be delayed. Ensure that medical
personnel are aware of the material(s) involved and take precautions to protect themselves.
Ingestion: Harmful if swallowed. Do not induce vomiting with out medical advice. Effects of exposure (ingestion) to
substance may be delayed. Call a physician or Poison Control Center immediately. Do not use
mouth-to-mouth method if victim ingested the substance; give artificial respiration with the aid of a pocket
mask equipped with a one-way valve or other proper respiratory medical device. Loosen tight clothing such
as a collar, tie, belt or waistband. If a person vomits place them in the recovery position so that vomit will
not reenter the mouth and throat. Rinse mouth. Keep victim warm and quiet. Treat symptomatically and
supportively. Ensure that medical personnel are aware of the material(s) involved and take precautions to
protect themselves.
Symptoms/effects:
Acute: No data available
Delayed: No data available
Immediate medical attention: WARNING: It might be hazardous to the person providing aid to give mouth-to-mouth respiration, because
the inhaled material is harmful. WARNING: It might be hazardous to the person providing aid to give
mouth-to-mouth respiration, because the inhaled material is corrosive. For severe burns, immediate
medical attention is required. If breathing has stopped, perform artificial respiration. Use first aid treatment
according to the nature of the injury. Ensure that medical personnel are aware of the material(s) involved
and take precautions to protect themselves.

SECTION 5. FIREFIGHTING MEASURES

Suitable extinguishing media: Dry chemical, soda ash, lime or dry sand. Consult with local fire authorities before attempting large scale
fire fighting operations.
Unsuitable extinguishing media: Do NOT use water or foam.
Specific hazards arising from the chemical
Hazardous combustion products: These products include: Carbon oxides Borates Metallic oxides
Other specific hazards: Closed containers may explode from heat of a fire.
Special precautions for fire-fighters:
Use water spray or fog; do not use straight streams. Dike fire-control water for later disposal; do not scatter the material. CAUTION: All these products
have a very low flash point: Use of water spray when fighting fire may be inefficient. Do not use straight streams. Runoff to sewer may create fire or
explosion hazard. May re-ignite after fire is extinguished. Do not get water inside containers. Cylinders exposed to fire may vent and release gasses
through pressure relief devices. Containers may explode when heated. Move containers from fire area if you can do it without risk.
Special protective equipment for fire-fighters:
Wear positive pressure self-contained breathing apparatus (SCBA). Structural fire fighters' protective clothing provides limited protection in fire situations
ONLY; it may not be effective in spill situations. Wear chemical protective clothing which is specifically recommended by the manufacturer. It may
provide little or no thermal protection.

SECTION 6. ACCIDENTAL RELEASE MEASURES

Personal precautions: Avoid contact with skin, eyes, and clothing. Keep people away from and upwind of spill/leak. Use
spark-proof tools and explosion-proof equipment. Remove all sources of ignition. Do not touch damaged
containers or spilled material unless wearing appropriate protective clothing (Section 8). Warn
unnecessary personnel to move away. Stop leak if you can do it without risk. Ensure adequate ventilation.
Isolate the hazard area and deny entry to unnecessary and unprotected personnel.
Personal protective equipment: Wear eye protection (splash goggles) and face protection (full length face shield). Lab coat. Vapor
respirator. Be sure to use a MSHA/NIOSH approved respirator or equivalent. Wear protective gloves
(nitrile).
Emergency procedures: Do not use water as spilled material may react with it. Isolate area until gas has dispersed. Do not clean-up
or dispose except under supervision of a specialist. ELIMINATE all ignition sources (no smoking, flares,
sparks or flames in the immediate area). Do not touch damaged containers or spilled material unless
wearing appropriate protective clothing. Warn personnel to move away. Prevent entry into sewers,
basements or confined areas; dike if needed.
Methods and materials for containment and cleaning up:
ELIMINATE all ignition sources (no smoking, flares, sparks, or flames in immediate area). Stop leak if without risk. Do not direct water at spill source.
DO NOT get water inside container. All equipment used when handling the product must be grounded. Absorb with DRY earth, sand or other
non-combustible material. Use clean non-sparking tools to collect material and place it into loosely covered plastic containers for later disposal. Do not
clean-up or dispose except under supervision of a specialist. Ventilate the area.
Environmental precautions:
Keep away from living quarters. Prevent further leakage or spillage if safe to do so. Water runoff can cause environmental damage. Prevent entry into
sewers, basements or confined areas; dike if needed.

SECTION 7. HANDLING AND STORAGE

Precautions for safe handling: Do NOT breath gas, fumes, vapor, or spray. Manipulate under an adequate fume hood. Do not ingest.
Avoid contact with skin and eyes. Keep away from heat and sources of ignition. Use explosion-proof
equipment. Use only non-sparking hand tool when handling this product. Ground all equipment containing
material. Take measures to prevent build up of electrostatic charge. Never add water to this product. Good
general ventilation should be sufficient to control airborne levels. Keep container dry. Handle and open
container with care. Wear suitable protective clothing, gloves and eye/face protection. When using do not
eat, drink, or smoke. Keep away from sources of ignition.
Conditions for safe storage: Store locked up. Keep away from sources of ignition. Store and use away from heat, sparks, open flame,
or any other ignition source. Store in a cool, dry place. Keep containers tightly closed in a dry, cool, and
well-ventilated place. Keep away from incompatibles. Containers which are opened must be carefully
resealed and kept upright to prevent leakage. Avoid prolonged storage periods. Store under inert gas (e.g.
Argon).
Storage incompatibilities: Store away from oxidizing agents
