Special Fire Fighting Procedure: In case of fire in an adjacent area, use water, CO

or dry che
mical extinguishers if cells
are packed in their original containers since the fuel of the fire is basically paper products. For bulk quantities of
unpackaged cells use LITH-X (Graphite Base). In this case, do not use water.
As with any fire, wear self-contained breathing apparatus to avoid inhalation of hazardous decomposition products.
