When not mounted in helicopter, fire

extinguishers. Injury to personnel can
result. Remove cartridges (squibs)
when extinguishers are removed for
storage.
Whenever fire extinguisher cartridges
are not installed, the positive terminal
must be shunted to the cartridge
body to prevent accidental firing and
discharge from stray voltages.
