	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Headache. Dizziness. Drowsiness. Nausea.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Redness. Pain.	Protective gloves.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes	Redness. Pain.	Wear safety spectacles 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	Burning sensation in the throat and chest. Further see Inhalation.	Do not eat, drink, or smoke during work.	Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention .

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. Physical dangers The vapour is heavier than air and may travel along the ground; distant ignition possible. Chemical dangers Reacts with acids, bases and strong oxidants. Decomposes on burning. This produces toxic and corrosive fumes including hydrogen sulfide and sulfur oxides.	Formula: C₆H₁₄S / CH₃(CH₂)₅SH Molecular mass: 118.2 Boiling point: 151°C Relative density (water = 1): 0.84 Solubility in water: none Vapour pressure, kPa at 40°C: 0.16 Relative vapour density (air = 1): 5.04 Flash point: 30°C Explosive limits, vol% in air: 0.7-5.5 Octanol/water partition coefficient as log Pow: 5.35
