Users should be trained to recognize abnormal conditions which could signify malfunction or failure of the equipment to
properly operate as follows:
Failure Of The Starter Candle
If the starter candle fails to actuate when the adjustment strap is pulled, an additional sharp pull on the strap may be sufficient
to dislodge the lanyard pin and actuate the device. If the device still fails to actuate, the hood will continue to function,
although the initial purge capability is lost. Sticking the fingers into the neckseal to allow a large lung inhalation may be
required to enable sufficient breathing volume until the chemical regeneration system begins producing a surplus of
oxygen.
Inadequate Oronasal Mask Seal
Absence of a tight seal of the oronasal cone to the face may result in excess leakage of the exhaled breath into the hood,
short circuiting the oxygen-generating canister. This condition may result in a build-up of CO2 within the rebreathing volume
in the hood. Excessive CO2 is normally indicated by breathing distress such as rapid and labored breathing accompanied
by a general feeling of insufficient ability to get one’s breath, although there is no restriction to breathing. Presence of
moisture or fogging on the visor and the sensation of air escaping from the mask, particularly around the nose and eyes, are
indications of a lack of proper fit. Adjustment of the mask straps and mask position to minimize leakage should rapidly
alleviate the problem. If the perception of breathing distress persists, the user should quickly go to a safe area and remove
the PBE and don alternate breathing equipment if required.
Loss Of Infiltration Seal
The smoke and toxic fumes generated by the combustion of most aircraft cabin interior materials has many strong irritants.
The continued presence of strong irritation odors inside the hood resulting in eye and respiratory tract discomfort is a good
indicator of the lack of an effective infiltration seal. Verify that the seal is in contact with the skin or the neck and does not
have clothing or jewelry trapped in the seal, or hair protruding between the seal and the neck. If the condition persists, or
there is evidence of a tear in the neckseal, the user should go quickly to a safe area and don alternate breathing equipment
if required.
