NEW YORK — A city official on Sunday proposed new gas safety measures after a house explosion and fire killed a woman and injured three passersby.
Saturday’s blast in Brooklyn’s Borough Park neighborhood happened after a stove was removed from a gas line that may not have been properly disconnected, authorities said.
‘‘I have been surprised to learn how easy it is for someone to improperly disconnect, replace, or modify the connection between home appliances, like stoves and hot water heaters, and the gas line,’’ Brooklyn Borough President Eric Adams said.
Authorities were conducting a search of the three-story house for clues to help determine the cause of the apparent gas leak believed to have triggered the explosion.
The blast follows two other fatal gas explosions in recent years in the city. One killed eight people in East Harlem last year. Two people died in an East Village explosion this year.
Governor Andrew Cuomo ordered the state’s Department of Public Service, which regulates utility companies, to launch an investigation into ‘‘the latest in a disturbing trend of incidents.’’
Adams said new gas safety measures might involve requiring licensure to disconnect, replace, or modify gas lines linked to home appliances.
Officials suspect the blast originated in an apartment on the second floor, where a tenant had recently disconnected a stove. Councilman Brad Lander said the tenant had moved out about a week ago.
He said the woman who died was in her 60s and was from the Dominican Republic. He said she lived in a third-floor apartment with her daughter, who was away at the time.
