Thionyl chloride is a colorless to pale yellow liquid with a suffocating odor.
The reaction of one mole of thionyl chloride with water produces two moles of hydrogen chloride and one of sulfur dioxide, so that 1 ppm of thionyl chloride can be shown to produce a total irritant gas concentration of 3 ppm.
The exposure limit for hydrogen chloride is 5 ppm as a ceiling limit; for sulfur dioxide, the limit is a TWA of 2 ppm.

 Treatment of lithium anodes - Patent 4503088
A method for reducing passivation of a lithium electrode used in a cell having a thionyl chloride liquid cathode is disclosed, the method comprising providing on the surface of the electrode a polymer Film selected from the group of alkyl acrylate and alkyl substituted acrylate polymers, the Film containing a salt in the polymer matrix.
In accordance with the invention a lithium or lithium alloy anode is protected by a polymeric film preferably made by dissolving an alkyl 2 cyanoacrylate in a solvent and including in the mixture a salt which is soluble in the solvent, evaporating the solvent and allowing the cyanoacrylate to polymerize on the lithium anode surface.
When the thus protected lithium anode surface comes in contact with thionyl chloride in the cell, it is believed that complex chemical reactions occur which result in at least removal of nitrogen from the polymer coating and the formation of an acrylate or a non-nitrile substituted acrylate polymer as the basis of the coating.

 House Of Batteries - How to Select the Right Battery - Lithium Thionyl Chloride
Thionyl chloride-lithium cells have the highest energy density of all lithium types and are manufactured in welded, hermetically sealed cases.
For example, wireless passive infrared (PIR) sensors used in security systems typically draw very small currents (tens of uA) in quiescent mode and 7.5 mA to 10 mA when transmitting.
Under those operating conditions, a thionyl chloride/lithium cell offers a service life up to 2-1/2 times longer than either a poly (carbon monofluoride) or manganese-dioxide lithium cell of the same size.
