When you are dealing with this kind of chemical, you should be cautious. For one thing, it is irritating to eyes, respiratory system and skin and may cause inflammation to the skin or other mucous membranes. And it may cause sensitization by skin contact and have possible risk of harm to the unborn child. For another thing, it is toxic which may at low levels cause damage to health. And it may cause cancer and will be toxic if by inhalation, in contact with skin and if swallowed. Besides, if in case of contact with eyes, rinse immediately with plenty of water and seek medical advice. In addition, it is highly flammable which may catch fire in contact with air, only needing brief contact with an ignition source. And it has a very low flash point or evolve highly flammable gases in contact with water. 

There, you should take different measures to deal with different cases. The first important thing is to wear suitable protective clothing, and then try to avoid contacting with skin and eyes and avoid exposure - obtain special instruction before use. Besides, do not breathe gas/fumes/vapor/spray (appropriate wording to be specified by the manufacturer).

Additionally, you could convert the following datas into the molecular structure:
(1)Canonical SMILES: C1=CC=C2C(=C1)C=CC=C2F
(2)InChI: InChI=1S/C10H7F/c11-10-7-3-5-8-4-1-2-6-9(8)10/h1-7H
(3)InChIKey: CWLKTJOTWITYSI-UHFFFAOYSA-N
