FIRE engulfed a Croydon shed containing 12 small gas cylinders on Thursday afternoon, causing $30,000 of damage.
The cylinders did not explode and the MFB and CFA classified the fire as "contained" at about 2.15pm.
MFB commander Peter Egan said at this stage the fire was not suspicious.
"We got a call at about 1.45pm to find two sheds in Edward Court, Croydon, which were well alight," he said.
"The fire did impinge onto the property at the rear of the house, but it caused no further damage.
"The shed was being used as a workshop and for storage."
Commander Egan said they "didn't have any problems" with the 12 gas cylinders inside the shed as they did not explode.
Nine vehicles attended the fire, which reportedly reached 10 metres high.
Witness Rohan McMahon was near the blaze.
"I was at my friend's property about four houses down and heard two big explosions," he said.
"We went out the front and straight away heard sirens. The sheds were completely engulfed."
Edward Court is about 100 metres from Dorset public golf course.
