Safety information
WARNING:
Read the safety information fully before using the
aspida
.
WARNING:
Do NOT attempt to charge the batteries while the device is inside the hyperbaric
chamber.
High volume audible alarm
The
Aspida
employs high volume warning alarms with a sound pressure level at 1m of 95dB in the case
of normal gas alarms, and up to 110dB in the case of the man-down alarm.
As the man down sounder is disabled by default when supplied but may be user enabled, care should
be taken to minimise exposure to the sounder. The
aspida
unit should always be worn away from the
head in order to minimise close range exposure to the alarm.
WARNING:
The 110dB man-down alarm can, when enabled, be manually activated at any
time by holding the
button if the panic alarm is configured to be available. Care should be
taken not to activate this alarm when the
Aspida
unit is in close proximity to the ears.
WARNING:
Do NOT exceed
2 bar/min
atmospheric pressure change when using the HBOT
Aspida.
Electrochemical oxygen sensor
The oxygen sensor used in the
Aspida
is an electrochemical sensor which contains potassium
hydroxide. Under normal conditions the sensor is sealed. To prevent leakage, the unit must not be
exposed to temperatures outside the specified range, or be exposed to organic vapours, which may
cause physical damage to the body of the sensor. The unit must not be stored in areas containing
organic solvents or in flammable liquid stores.
