AVOID ALL CONTACT!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Sore throat. Cough. Burning sensation. Laboured breathing. Shortness of breath.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Refer 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.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion	Abdominal pain. Burning sensation. Shock or collapse.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention .

2-CHLOROPROPIONIC ACID

ICSC: 0644

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS-TO-YELLOW LIQUID WITH PUNGENT ODOUR. Physical dangers Chemical dangers Decomposes on heating. This produces toxic and corrosive fumes including hydrogen chloride. Reacts violently with strong bases and strong oxidants. The substance is a medium strong acid. Attacks many metals. This produces flammable/explosive gas (hydrogen - see ICSC 0001).	Formula: C₃H₅ClO₂ / CH₃CHClCOOH Molecular mass: 108.5 Boiling point: 186°C Melting point: -12°C Density: 1.3 g/cm³ Solubility in water: miscible Vapour pressure, kPa at 20°C: 0.10 Relative vapour density (air = 1): 3.75 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.001 Flash point: 106°C c.c. Auto-ignition temperature: 500°C Explosive limits, vol% in air: 3.7-14.3 Octanol/water partition coefficient as log Pow: 0.76
