Hazards and Protection.
Storage
Store in a cool, dry place. Store in a tightly closed container. Keep under a nitrogen blanket.
Handling
Wash thoroughly after handling. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation. Do not allow contact with water. Use only in a chemical fume hood.
Protection
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
Respirators
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
Small spills/leaks
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Wash area with soap and water. Provide ventilation.
Stability
Stable under normal temperatures and pressures.
Incompatibilities
Phosphates; strong oxidizing agents; strong acids; bases; metals.
Decomposition
Hydrogen fluoride, antimony/antimony oxides.

Fire.
Fire fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Extinguishing media: Substance is noncombustible; use agent most appropriate to extinguish surrounding fire. DO NOT USE WATER!
Fire potential
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
Hazards
Reacts violently with water, to form poisonous hydrogen fluoride fumes. If confined and wet can cause explosion. May cause fire in contact with Hazardous polymerization may not occur.
Combustion products
Fire will produce irritating, corrosive and/or toxic gases.

Exposure effects
Respiratory depression, abnormally low blood pressure, and low heart rate may be seen. Coma and seizures may be seen in acute poisoning with antimony pentafluoride. Birth defects were not found in the children of women occupationally exposed to antimony dust. Women exposed occupationally to antimony dust had an excessive prevalence of spontaneous abortions, premature deliveries, and various gynecological disorders. <br>Antimony at concentrations of less than 0.05 to 12.9 nanograms/gram was found in breast milk obtained between 15 days and 3 months after delivery in 16 out of 21 Italian women tested. <br>Cases of sexual dysfunction have been mentioned among male workers exposed to antimony.
   Ingestion
May cause severe gastrointestinal tract irritation with nausea, vomiting and possible burns.
   Inhalation
May cause severe irritation of the upper respiratory tract with pain, burns, and inflammation. Inhalation may be fatal as a result of spasm, inflammation, edema of the larynx and bronchi, chemical pneumonitis and pulmonary edema.
   Skin
Contact with liquid is corrosive and causes severe burns and ulceration.
   Eyes
Contact with liquid is corrosive to the eyes and causes severe burns.

First aid
 
   Ingestion
Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid immediately.
   Inhalation
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
   Skin
Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
   Eyes
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
