SECTION 4. FIRST AID MEASURES

Inhalation: Call a poison center or doctor if you feel unwell. 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: If skin irritation occurs get medical advice/attention. Remove and wash contaminated clothing before reuse.
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. Contact with
material may irritate or burn eyes. 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: Do not induce vomiting with out medical advice. If swallowed, seek medical advice immediately and show
the container or label. 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: Redness.
Delayed: No data available
Immediate medical attention: 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, CO2 , sand, earth, water spray or regular foam Consult with local fire authorities before
attempting large scale fire fighting operations.
Specific hazards arising from the chemical
Hazardous combustion products: These products include: Carbon 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. 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. 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. Dust
respirator. Be sure to use a MSHA/NIOSH approved respirator or equivalent. Wear protective gloves
(nitrile).
Emergency procedures: Prevent dust cloud. In case of a spill and/or a leak, always shut off any sources of ignition, ventilate the
area, and excercise caution. 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. Ventilate the area. Absorb with an
inert material and put the spilled material in an appropriate waste disposal container. Use clean non-sparking tools to collect absorbed material.
Environmental precautions:
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: Avoid inhalation of vapor or mist. Avoid contact with skin and eyes. 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: Keep only in the original container in a cool 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.
Storage incompatibilities: Store away from oxidizing agents
