The mystery revealed

Because everyone is dying to know the answer to the Quiz

It was a fireman's kit... of course!

Green foam = the hose
Goggles = Gas mask (that's an easy one)
Dummy = An air blower to help the fire
Brush = To scrub the dust off the walls (fires make lots of dust)
Hair brush = 'To fix your hair up' (I suppose helmet head is an ocupational hazard after all)
