3. Hazards Identification
EMERGENCY OVERVIEW
Severely irritating to the eyes, mucous membranes and skin. Inhalation may cause digestive system
disorders and liver toxicity. Certain arsenic compounds are recognized cancer-causing agents.
Forms hydrofluoric acid on contact with moisture. Nonflammable.

HEALTH EFFECTS:
Exposure Limits Irritant Sensitization
No Yes No
Teratogen +Reproductive Hazard Mutagen
No No No
Synergistic Effects
None Reported
Carcinogenicity: -- NTP: Yes IARC: Yes OSHA: Yes
EYE EFFECTS:
Contact with the eyes causes severe irritation or burns. Burns are progressive while any unneutralized fluoride
ions remain
SKIN EFFECTS:
Contact with skin causes severe irritation or burns. Certain inorganic arsenic compounds have been associated
with a carcinogenic response to skin in animals and humans. Burns are progressive while any unneutralized
fluoride ions remain
INGESTION EFFECTS:
Ingestion causes weakness and irritation of the mouth and stomach. An overdose can cause arsenic poisoning,
although symptoms may be delayed.
INHALATION EFFECTS:
Inhalation causes irritation of the nose and throat. Symptoms include irritation, redness, and pain. Arsenic
poisoning may occur from excessive exposure.
Chronic exposure to fluorides may cause fluorosis, a degenerative condition of bone tissue.
There is sufficient evidence that certain inorganic arsenic compounds are carcinogenic, although arsenic
trifluoride, as such has not been shown to be a carcinogen.

4. First Aid Measures
EYES:
PERSONS WITH POTENTIAL EXPOSURE TO ARSENIC TRIFLUORIDE SHOULD NOT WEAR
CONTACT LENSES. Flush contaminated eye(s) with copious quantities of water. Part eyelids to assure
complete flushing. Continue for a minimum of 30 minutes.
SKIN:
MSDS: G-13
Revised: 6/7/96 Page 2 of 7
PRODUCT NAME: ARSENIC TRIFLUORIDE
Remove contaminated clothing as rapidly as possible. Flush affected skin with plenty of water and mild soap.
Seek immediate medical attention. Flush affected area with copious quantities of water. Remove affected
clothing as rapidly as possible. Dermal burns may be treated with calcium gluconate gel or slurry in water or
glycerine. This compound binds the active fluoride in an insoluble form and limits burn extension and relieves
pain. Treat systemic poisoning similar to inhalation.
INGESTION:
Treat systemic poisoning similar to inhalation. Call a physician or Poison Control Center at once.
INHALATION:
PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE TO
ARSENIC TRIFLUORIDE. RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF CONTAINED
BREATHING APPARATUS. Regard anyone exposed to arsenic trifluoride as having a potentially toxic dose.
Move the victim to an uncontaminated atmosphere. Keep the victim warm, quiet and at rest. Provide assisted
respiration if breathing has stopped. Administer oxygen if breathing is labored and when assisted respiration is
given. Medical attention is imperative. Advise physician of the possible cause of the problem and that he must
promptly inform himself (if not familiar with arsenic poisoning) of the toxic properties of this powerful
hemolytic agent.
5. Fire Fighting Measures
Conditions of Flammability: Nonflammable
Flash point: Method: Autoignition
None Not Applicable Temperature: None
LEL(%): None UEL(%): None
Hazardous combustion products: None
Sensitivity to mechanical shock: None
Sensitivity to static discharge: None
FIRE AND EXPLOSION HAZARDS:
None.
EXTINGUISHING MEDIA:
Do not use water on adjacent fires, which will form irritating and toxic vapors of hydrogen fluoride. Use CO2
or dry chemical or other inert gas.
FIRE FIGHTING INSTRUCTIONS:
Wear self-contained breathing apparatus and full protective gear. Special personnel decontamination procedures
are required. Consult HAZMAT specialist.
6. Accidental Release Measures
Evacuate all personnel from affected area. Use appropriate protective equipment. If leak is in user鈥檚 equipment,
be certain to purge piping with inert gas prior to attempting repairs. If leak is in container or container valve,
contact the appropriate emergency telephone number listed in Section 1 or call your closest BOC location.
Collect and place in a sealed, labeled container for disposal.
7. Handling and Storage
MSDS: G-13
Revised: 6/7/96 Page 3 of 7
PRODUCT NAME: ARSENIC TRIFLUORIDE
Use only in well-ventilated areas. Valve protection caps must remain in place unless container is secured with
valve outlet piped to use point. Do not drag, slide or roll cylinders. Use a suitable hand truck for cylinder
movement. Use a pressure reducing regulator when connecting cylinder to lower pressure (<500 psig) piping or
systems. Do not heat cylinder by any means to increase the discharge rate of product from the cylinder. Use a
check valve or trap in the discharge line to prevent hazardous back flow into the cylinder. Installation of a cross
purge assembly between the cylinder and the regulator is recommended. Protect cylinders from physical
damage. Store in cool, dry, well-ventilated area of non-combustible construction away from heavily trafficked
areas and emergency exits.
Do not allow temperature where cylinders are stored to exceed 125 oF (52 oC). Cylinders should be stored
upright and firmly secured to prevent falling or being knocked over. Full and empty cylinders should be
segregated. Use a "first in-first out" inventory system to prevent full cylinders being stored for excessive periods
of time.
Never carry a compressed gas cylinder or a container of a gas in cryogenic liquid form in an enclosed space such
as a car trunk, van or station wagon. A leak can result in a fire, explosion, asphyxiation or a toxic exposure.
