Any AFES in need of maintenance or repair is more prone to
accidental discharge. Accidental discharge could lead to frostbite or
other injury. Small parts or tools become dangerous projectiles
when propelled by Halon discharging at 750 psi.
Do not strike cylinder bottles with tools. Do not drop cylinder bot-
tles. Be careful when handling cylinder bottles to prevent acciden-
tal discharge.
