SECTION 4. FIRST AID MEASURES

Inhalation: Call a poison center or doctor if you feel unwell. 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: Call a poison center or doctor if you feel unwell. Effects of exposure (skin contact) to substance may be
delayed. Remove and wash contaminated clothing before re-use. 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. Effects of exposure (ingestion) to substance may be
delayed. 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 , water spray, or alcohol-resistant 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 Halogenated compounds
Other specific hazards: WARNING: Highly toxic HCl gas is produced during combustion.
WARNING: Highly toxic HF gas is produced during combustion.
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. Do not clean-up or dispose except under supervision of a specialist. 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:
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: 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: Store locked up. Keep containers tightly closed 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. Store under inert gas (e.g. Argon). Moisture sensitive.
Storage incompatibilities: Store away from oxidizing agents
