For Leading Seaman Brad Watson and Able Seaman Ben Price, recent advice that ‘portable breathing apparatus rigs are now cleared for release and ready for collection’, represented the realisation of a concept they developed to improve the way navy does business when using harmful chemicals.
Their concept has provided a safer way of conducting maintenance, while helping to reduce operating costs.
The program is designed to encourage navy aviation personnel to present their innovative concepts for improved capability.
Previously the Fleet Air Arm used a face mask respirator fitted with disposable filters to protect against harmful substances in the workplace.
These filters were discarded after a single use and issues were being experienced with the face mask as it provided reduced protection for personnel with facial hair.
Fleet Air Arm compared the cost of an annual supply of disposable filters to the outlay required to purchase 22 of the positive breathing apparatus units.
Business manager Dave Robinson said despite the initial outlay for the purchase of the new units, there would be savings over the longer term and increased protection for maintenance staff.
After identifying ongoing issues and potential costs, LS Watson and AB Price researched the WHS Act and Australian and New Zealand Standards AS/NZS 1715 to come up with a solution.
Their research identified a company which was able to construct a portable unit containing multiple types of filters capable of eliminating harmful vapours and particulates.
“The machine receives pressurised air from any type of air compressor and purifies it to safe, clean breathable air in accordance with WHS standards,” LS Watson said.
“The clean air is made available to a user wearing a hood, allowing successful operation even if the operator has facial hair because of the positive pressure delivered by the unit.
“The use of this positive airflow hood also eliminated the requirement for annual fitment checks.
“The unit can provide air to multiple users at the same time, or one user operating a pneumatic tool.”
The machine was modified slightly during the trial period to improve storage onboard ships and to make the machine more durable.
Small adjustments were made, such as flexible air ports, improved storage bags and recessed gauges.
AB Price said that initial comments they received about the unit during the trial were positive.
AB Mitchell Sama, an Aviation Technician - Avionics at 808 Squadron who trialled the apparatus, said it was a big improvement compared to full face respirators.
“The biggest change is the addition of an oxygen bottle that immediately takes over as a redundancy should you lose air from the lines to the machine,” he said.
‘This is reassuring in cases where you are in places or positions that don't permit you to leave quickly.
“It also allows operators to stay composed and remove themselves from an unfavourable situation in a timely manner.”
The apparatus can be used when priming, painting and sealing, processes which employ chemicals which may be hazardous if inhaled.
