PRE-USE CHECKS
Note The following instructions are for the FH3 headtop and breathing hoses.
These instructions must be used alongside the Operating and Maintenance
Instructions for the chosen PAPR.
Note The life of a headtop has many
factors that make it difficult to predict
service life. Therefore the headtop
should be inspected carefully before
and after each use to ensure that
it has not become damaged. As a
guideline we would anticipate that
a headtop used indoors and for
'occasional' use would have a service
life of about five years, provided
that the equipment is stored and
maintained correctly.
HOSES
Inspect the breathing hose for any
signs of creasing and ensure that it is
not torn
Ensure that both ends of the breathing
hose are free from dirt or debris and
that there is no damage to either end
For a Spirit hose check that the red
locking collar on the breathing hose
female connector works correctly and
is free from damage, ensure that the
witness marks are aligned with the
opening in the black collar and ready
to place over the air outlet on the
Spirit blower
For a Tornado/Proflow hose check
that the 'O' ring is in place and in
good condition
Note
'O' rings and gaskets on all
hoses should be replaced at least
annually.
HEADTOP & HELMET
Check that the headtop is in a
good, clean condition, free from
any damage and is not torn; paying
attention to the hose inlet, also the
browband, faceseal, exhale valve and
head harness
Inspect the visor for any signs of
damage, ensuring it is free from deep
scratches, cracks or crazing
Make sure that there are no blemishes,
solvents or paint that may obscure
vision
Make sure faceseal band is correctly
attached to locating tabs
Fully loosen the handwheel at the rear
of the headtop to facilitate donning
