b. Notify supporting Fire Marshal of require-
ment to recharge empty cylinders.
c. Avoid dropping or rough handling. During
transportation or storage, secure cylin-
ders firmly to avoid rough handling.
d. Store only in a cool, dry area in an upright
position. Do not expose to temperatures
above 120°F (48 °C).
e. Visually inspect for any signs of corrosion
or mechanical damage. If such indicators
are present, immediately request sup-
porting Fire Marshal to conduct an
inspection and weight test.
f. Check spare Halon cylinder not attached

1) If pressure gauge is color coded,
needle must be in green range.
2) If pressure gauge is not color coded,
needle should indicate 370 psi at 70
°F, 395 at 80 °, 430 at 90 °, and 470
at 100 °.If pressure loss, adjusted for
temperature, is greater than 10 per-
cent, replace active cylinder with
spare. Request supporting Fire Mar-

1301 cylinder as necessary, and also
check the manifold assembly.
