Stockings used by firemen? (4)
I believe the answer is:
hose
'stockings' is the definition.
(hose refers to stockings, tights etc)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for hose that I've seen before include "Stockings, etc." , "Breeches (worn with a doublet)" , "Garden implement" , "Water pipe" , "Flexible pipe for liquid" .)
