Residents of Atomic Junction were thrown into a state of pandemonium after two gas filling stations in the area were engulfed in flames on Saturday night.
Ghana President Nana Addo Dankwa Akufo-Addo has said his government is determined to ensure that incidents of gas explosion do not occur again.
Dr Bawumia, who visited some hospitals that received the casualties including the Legon, 37 Military, Ridge and the Police hospitals, extended condolences to the bereaved families, and wished those who had been injured speedy recovery.
Ghana's deputy information minister Kojo Oppong-Nkrumah said the fire has been controlled and firefighters are now controlling the second explosion. "There are quite a number also injured".
Legon is a suburb of the capital, and is also home to the main campus of the University of Ghana. "There are lots of buildings and a lot of people in the area, including many street sellers".
Reports suggest a tanker delivering natural gas caught fire. The petition is asking for stations to be situated "at least 50 meters away from residences and 100 meters from schools and hospitals need to enforce these rules".
Abena Awuku, a Ghanaian living in the Netherlands, proposed the measures on the change.org site, saying fuel stations were "all disasters waiting to happen and the time to act is now".
"These deaths could have easily been prevented, so let's prevent them from ever occurring again in the future".
