TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire.

Powder, carbon dioxide. NO hydrous agents. NO water.
EXPLOSION

In case of fire: cool drums, etc., by spraying with water but avoid contact of the substance with water.
EXPOSURE
STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
Inhalation Corrosive. Burning sensation. Cough. Laboured breathing. Nausea. Shortness of breath. Sore throat.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. Refer for medical attention.
Skin Redness. Serious skin burns. Pain.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention. Apply calcium gluconate to the burn areas.
Eyes Corrosive. Redness. Pain. Severe deep burns.
Face shield or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion Abdominal cramps. Abdominal pain. Burning sensation. Diarrhoea. Nausea. Vomiting.
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. Do NOT absorb in saw-dust or other combustible absorbents.
Unbreakable packaging; put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs.

ANTIMONY PENTAFLUORIDE ICSC: 0220
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
OILY COLOURLESS HYGROSCOPIC LIQUID

CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing toxic and corrosive fumes including antimony and fluorine. Reacts violently with water forming toxic and corrosive hydrogen fluoride (see ICSC 0283). Attacks glass, copper and lead.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as Sb) 0.5 mg/m as TWA; (ACGIH 2004).
MAK: (as Sb) Carcinogen category: 2; Germ cell mutagen group: 3A; (DFG 2005).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the eyes, the skin and the respiratory tract. Inhalation of the vapour may cause lung oedema (see Notes). The substance may cause effects on the blood, heart muscle, kidneys and liver, resulting in cardiac disorders and impaired functions.

PHYSICAL PROPERTIES
Boiling point: 141C
Melting point: 8.3C
Relative density (water = 1): 3.00
Solubility in water: reaction
Vapour pressure, kPa at 25C: 1.33
ENVIRONMENTAL DATA

NOTES
Reacts violently with fire extinguishing agents such as water or hydrous agents. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered. Also consult ICSC 0283 (Hydrogen fluoride). Card has been partly updated in October 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
