Meanwhile, Prabhakar who has been in the field for the past 20 years said it was rare for a domestic refrigerator to blast as it contains negligible amount of gas, mostly in grams, which is insufficient to cause a blast. “There are no chances for it to blast because of gas leakage. The presence of such small amounts of gas can, at its best, cause a spark”. He added that after a prolonged use, older refrigerators have high chances for such incidents.
