Remove the cap (either paper or plastic) from either
the smoke or illumination end of the signal, as applicable.
Grasp the signal firmly with one hand and hold the
signal an arm's length away from the body in a horizontal position
with each end of the signal pointed away from the body.
Insert the index finger of your free hand into the pull
ring and break the soldered end of the cap free. If the soldered cap
does not release, bring the pull ring down over the rim of the can
and press down with the heel of your hand, using the ring as a lever
to break the seal.
Use extreme care when using the signal as an
illumination device. Hot, molten residue from the
burning signal can cause serious bums on the body
or puncture the raft.
