Hazards and Protection.
Store in a cool, dry place. Store in a tightly closed container. Keep under a nitrogen blanket.
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.
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.
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.
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.
Stable under normal temperatures and pressures.
Phosphates; strong oxidizing agents; strong acids; bases; metals.
Hydrogen fluoride, antimony/antimony oxides.
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!
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
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.
Fire will produce irritating, corrosive and/or toxic gases.
NIOSH REL*: TWA 0.5 mg/m3 OSHA PEL*: TWA 0.5 mg/m3 [*Note: REL and PEL also apply to other antimony compounds (as Sb).] IDLH 50 mg/m3 (as Sb)
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.
May cause severe gastrointestinal tract irritation with nausea, vomiting and possible burns.
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.
Contact with liquid is corrosive and causes severe burns and ulceration.
Contact with liquid is corrosive to the eyes and causes severe burns.
Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid immediately.
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
