16.19 Twin cylinders should be carried vertically ensuring
that a firm grip is taken around the cylinder handle as
shown. Do not lift the cylinder using the
cylinder hand wheel – 300 bar cylinder outlets
have increased jet reaction from inadvertent release
of stored pressure which could lead to injury (see
images 1136767 and 1136766 right).
Cylinder pack acceptance test
16.20 Examine both cylinders, if steps a, b, c or d apply, the
cylinder pack is to be treated as defective:
(a) The hydraulic test is out of date see ‘ yellow
label - date of next test’. Do not use cylinder once month and year shown has been reached.
(b) The body of the cylinder is scored so as to reveal the carbon fibre matrix.
(c) After removing the protective blank cap the cylinder connection thread is damaged or
contaminated with dirt or debris.
(d) The carrying handle is damaged.
(e) Note the cylinder bar code number for entry into the BA log book.
Cylinder replacement
Note: the cylinder bar code number should be recorded in the BA log book after every change of
cylinder. It is not required to be recorded in the log book for every ’A’ test.
Cylinder removal EDBA
16.21 The BA set should be placed on the work surface cylinder downward. Unscrew and remove the
reducer.
Note: ensure all pressure is removed from the BA set prior to attempting to remove the cylinder.
The Bodyguard display must read 0 bar.
16.22 Remove anti-entanglement straps from BA set shoulder straps.
16.23 Press the spring plate on the top cylinder retaining bracket of the BA set away from the cylinder
pack and towards the backplate.
16.24 Whilst maintaining pressure on the spring plate, push the BA set away from the top of the
cylinder pack and towards the reducer. The BA set will
detach from the cylinder pack.
16.25 Unfasten securing straps, remove cylinder cover, clean
cylinder using Wypall x80 cloth and Safetywash solution.
Mark cylinder empty (M/T) on the black quarter shoulder.
Fitting the cover to the cylinder
