Endure gas explosion by gear at work (9)

I believe the answer is:

dungarees

I'm a little stuck... Click here to teach me more about this clue!

'by gear at work' is the definition.
I can't tell whether this defines the answer.

'endure gas explosion' is the wordplay.
'explosion' indicates an anagram.
'endure'+'gas'='enduregas'
'enduregas' with letters rearranged gives 'DUNGAREES'.

Can you help me to learn more?

(Other definitions for dungarees that I've seen before include "Worker's trousers with a bib" , "garment" , "Hard-wearing work trousers with a bib" , "Overall" , "Durable overalls" .)

I've seen this clue in the Sydney Morning Herald.
