HEAD Range - HOW IT WORKS
Automatic alarm initiation which states the apparatus is active: This first alarm will pulse five times to state the activation of the apparatus.
Chlorate candle releases O2‚ into the breathing bag automatically: The chlorate candle will emit five litres of O2 into the breathing bag.
This is to aid the user on their first initial breath.
Donning and first exhalation, KO2 removes CO2‚ from exhalation breath: The KO2‚ activates from the moisture of your exhalation breath.
This reaction removes the CO2‚ and produces O2‚ which flows into the breathing bag.
Dwell period, oxygen has been generated and is within the breathing bag ready to be inhaled.
Inhalation of O2‚ from the breathing bag: The O2‚ produced from the KO2‚ is now drawn from the breathing bag and then through the generators, breathing tubes and into the oronasal mask for the user to breathe.
This cycle then continues, this is a closed circuit breathing apparatus, the user is recycling their own breath.
Alarm initiated at 2/3 of the apparatus’s duration and again at full duration: The alarm at 2/3 of the apparatus’s duration informs the user of the O2‚ level.
The alarm will continue pulsing from the 2/3 mark till the full duration, the alarm then changes to a constant pulse to state to remove the apparatus if the user is within a respirable atmosphere.
