Gas Locker.

Man has an externally accessible gas locker that normally holds two European 11Kg cylinders. For shipping to Australian these cylinders have been removed. On arrival, new Australian cylinders will bought.

The locker was then cleaned, first with a pressure washer...

...then by hand with hot soapy water. And finally the locker was sprayed with Cypermethrin insect spray.

Total time about 2 hours.
