	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.	NO contact with bases, oxidizing agents or reducing agents.	In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep drums, etc., cool by spraying with water.

AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Sore throat. Burning sensation. Laboured breathing.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Half-upright position. Refer immediately for medical attention.
Skin	Redness. Pain. Serious skin burns.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer immediately for medical attention.
Eyes	Redness. Pain. Severe deep burns.	Wear face shield or eye protection in combination with breathing protection.	Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.
Ingestion	Burning sensation in the throat and chest. Abdominal pain. Shock or collapse.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING

TRIFLUOROACETIC ACID

ICSC: 1673

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance FUMING COLOURLESS LIQUID WITH PUNGENT ODOUR. Physical dangers The vapour is heavier than air. Chemical dangers Decomposes on contact with hot surfaces or flames. This produces toxic fumes. The substance is a medium strong acid. Reacts violently with strong bases, reducing agents and oxidants. This produces toxic and corrosive fumes including hydrogen fluoride. Attacks many metals. This produces flammable/explosive gas (hydrogen - see ICSC 0001). Attacks some forms of rubber.	Formula: C₂HF₃O₂ / CF₃COOH Molecular mass: 114.0 Boiling point: 72°C Melting point: -15°C Relative density (water = 1): 1.5 Solubility in water, g/100ml at 20°C: 100 (very good) Vapour pressure, kPa at 20°C: 11 Relative vapour density (air = 1): 3.9 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.3 Octanol/water partition coefficient as log Pow: -2.1

EXPOSURE & HEALTH EFFECTS
Routes of exposure Serious local effects by all routes of exposure. Effects of short-term exposure The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation of fumes may cause lung oedema. See Notes.	Inhalation risk A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. Effects of long-term or repeated exposure

EXPOSURE & HEALTH EFFECTS

Routes of exposure
Serious local effects by all routes of exposure.

Effects of short-term exposure
The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation of fumes may cause lung oedema. See Notes.

Inhalation risk
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.

Effects of long-term or repeated exposure

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT
The substance is harmful to aquatic organisms.

NOTES
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.
