(1). Extremely flammable. This chemical has an extremely low flash point and boiling point, and gases that catch fire in contact with air.
(2). Highly flammable. This chemical may catch fire in contact with air, only need brief contact with an ignition source, have a very low flash point or evolve highly flammable gases in contact with water.
(3). Irritant. This chemical may cause inflammation to the skin or other mucous membranes.

Therefore, you should take the following measure to prevent from danger.
(1). Keep away from sources of ignition - No smoking
(2). In case of contact with eyes, rinse immediately with plenty of water and seek medical advice
(3). Do not empty into drains
(4). Take precautionary measures against static discharges
(5). Wear suitable protective clothing, gloves and eye/face protection.
(6). Keep container tightly closed and in a well-ventilated place
