It's believed the man was doing some welding in the garage of his Squadron Crescent home yesterday afternoon when the fire broke out.
He suffered burns to the lower part of his body while trying to put the fire out - two other residents were treated for smoke inhalation.
Fire crews were confronted with exploding ammunition in the garage when they arrived.
It's taken them more than 2 hours to extinguish and mop up the fire, which destroyed half the house and the garage.
