The blast, thought to have been caused by a gas leak, damaged 48 apartments in a 10-storey building in the industrial city of Magnitogorsk on Monday, killing at least seven people with 36 people still missing.
Video footage from the local emergency ministry showed a rescuer worker removing the baby dressed in pink socks and putting a blanket around it before he starts running towards an ambulance.
The current temperature in the city of Magnitogorsk, home to one of Russia’s largest steel plants in the Urals some 1,700 km east of Moscow, is -17 Celsius.
The fact that the 11-month-old infant, currently diagnosed with a serious freezer burn and a closed-head injury, was lying in his bed and was wrapped up in layers saved his life, a news agency reported, citing a regional emergency centre.
The baby was found when a rescuer heard him crying and “a large-scale operation was immediately organised,” another news agency reported, citing emergency officials. His removal was difficult because of unstable debris which posed risks for rescuers.
The boy’s mother is alive and has already arrived to the hospital.
The blast tore through the building in the city of Magnitogorsk, home of one of Russia’s largest steel plants, early on Monday morning, a public holiday in Russia, when many residents were asleep. Health Minister Veronika Skvortsova said on Monday that the chances of finding survivors were fading.
There have been several similar incidents in the country in recent years due to ageing infrastructure and poor safety regulations about gas usage.
