Substance/Mixture: Substance
Components: Methyltriphenylarsonium Iodide
Percent: >98.0%(T)
CAS Number: 1499-33-8
Molecular Weight: 448.18
Chemical Formula: C19H18AsI

SECTION 4. FIRST AID MEASURES

Inhalation: Immediately call a poison center or doctor. 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: Immediately call a poison center or doctor. 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: If this chemical contacts the eyes, immediately wash (irrigate) the eyes with large amounts of water,
occasionally lifting the lower and upper eyelids. If eye irritation persists get medical advice/attention. 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: Toxic if swallowed. 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 dangerous to the person providing aid to give mouth-to-mouth respiration, because
the inhaled material is toxic. 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 or water spray. 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 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. 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: Safety glasses. 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. 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. Dike far ahead of spill; use dry
sand to contain the flow of material. Ventilate the area.
Environmental precautions:
Keep away from living quarters. Environmental hazard. Do not let product enter drains. 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. Do not ingest. 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.
Storage incompatibilities: Combustible substances, Store away from oxidizing agents
