When you are dealing with this chemical, you should be much more cautious. For one thing, it is harmful which may cause damage to health. For another thing, it is toxic which at low levels cause damage to health. If by inhalation, in contact with skin and if swallowed, it will be very toxic. 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.

Therefore, you should take different measures to deal with different cases. Wear suitable protective clothing, gloves and eye/face protection. And if in case of contact with eyes, rinse immediately with plenty of water and seek medical advice and if in case of accident or if you feel unwell, seek medical advice immediately (show label where possible). Then while store it, keep the container tightly closed and in a well-ventilated place, away from sources of ignition - No smoking. 

In addition, you could convert the following datas into the molecular structure:
(1)Canonical SMILES: C(CS)S
(2)InChI: InChI=1S/C2H6S2/c3-1-2-4/h3-4H,1-2H2
(3)InChIKey: VYMPLPIFKRHAAC-UHFFFAOYSA-N
