ANTIMONY PENTAFLUORIDE

CAS: 7783-70-2

Fraction By Weight: 100.0%

Reports of Carcinogenicity:NTP:No IARC:No OSHA:No
Medical Cond Aggravated by Exposure:

First Aid: INHALATION: If adverse effects occur, remove to
uncontaminated area. Give artificial respiration if not breathing.
If breathing is difficult, oxygen should be administered by
qualified personnel. Get immediate medical attention. SKIN CONTACT:
Wash skin with soap and water for at least 15 minutes while
removing contaminated clothing and shoes. Get immediate medical
attention. Thoroughly clean and dry contaminated clothing and shoes
before reuse. Destroy contaminated shoes. EYE CONTACT: Immediately
flush eyes with plenty of water for at least 15 minutes. Then get
immediate medical attention. INGESTION: Get medical attention
immediately. ANTIDOTE: dimercaprol/oil, intramuscular.

Flash Point:No data available.
Extinguishing Media:regular dry chemical, carbon dioxide, water,
regular foam Large fires: Use regular foam or flood with fine water
spray.
Fire Fighting Procedures:Move container from fire area if it can be
done without risk. Cool containers with water spray until well
after the fire is out. Stay away from the ends of tanks.
Unusual Fire/Explosion Hazard:Negligible fire hazard. Oxidizer. May
ignite or explode on contact with combustible materials.

Neutralizing Agent:

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. NFPA 430 Code for the
Storage of Liquid and Solid Oxidizing Materials. Keep separated
from incompatible substances. Protect from physical damage. Store
in a cool, dry place. Store in a well-ventilated area. Store
outside or in a detached building. Store in a tightly closed
container. Store in a cool, dry place. Store in a well-ventilated
area. Notify State Emergency Response Commission for storage or use
at amounts greater than or equal to the TPQ (U.S. EPA SARA Section
302). SARA Section 303 requires facilities storing a material with
a TPQ to participate in local emergency response planning (U.S. EPA
40 CFR 355.30).
Other Precautions:

Respiratory Protection:The following respirators and maximum use
concentrations are drawn from NIOSH and/or OSHA. Measurement
Element: Antimony (Sb) 5 mg/m3 Any dust and mist respirator. Any
supplied-air respirator. 12.5 mg/m3 Any supplied-air respirator.
Any powered, air-purifying respirator with a dust and mist filter.

pressure-demand or other positive-pressure mode. Escape - Any
air-purifying respirator with a full facepiece and a
high-efficiency particulate filter. Any appropriate escape-type,
self-contained breathing apparatus. For Unknown Concentrations or
Immediately Dangerous to Life or Health - Any supplied-air
respirator with full facepiece and operated in a pressure-demand or
other positive-pressure mode in combination with a separate escape
supply. Any self-contained breathing apparatus with a full
facepiece.
Ventilation:Provide local exhaust or process enclosure ventilation
system. Ensure compliance with applicable exposure limits.
Protective Gloves:Wear appropriate chemical resistant gloves.
Eye Protection:Wear splash resistant safety goggles with a faceshield.
