WARNING
Lithium Thionyl Chloride Batteries
1.
Lithium Thionyl Chloride battery contents are potentially toxic, flammable
and explosive.
2.
Lithium Thionyl Chloride batteries should not be:
♦
short circuited or charged under any circumstances.
♦
used in excess of +70°C and never exposed to temperatures in excess of
+100°C.
♦
opened, punctured, crushed or tampered with.
3.
Batteries in storage should be kept in an isolated, dry, well ventilated cool
environment and kept out of direct sunlight. Storage temperatures should
be below +30°C.
4.
Batteries are susceptible to fire and abuse. Some manufacturers provide
batteries with a safety vent, which allows a controlled release of electrolyte
if these conditions prevail. If the EPD has been damaged in a manner that
could affect the battery, care must be exercised during battery replacement.
The battery may have vented into the EPD case and caused the EPD to
become pressurized.
5.
Electrolyte leakage can normally be detected by the smell of sulphur dioxide
and/or the presence of electrolyte solutes. If a leakage is suspected:
(i)
the battery should be removed from the EPD using protective
clothing, gloves, and goggles.
(ii)
the battery should be placed in a self-sealing polythene bag (or
equivalent) and disposed of in the correct manner (see below).
(iii)
Wash with copious amounts of water any areas that come into
contact with the electrolyte, especially the skin. Seek medical
advice if electrolyte comes in contact with the eyes.
6.
Batteries must be disposed of in accordance with the manufacturer’s
recommendation and Local/National regulations.
7. If LTC batteries are to be transported by aircraft the batteries must be in their
correct packaging.
