Following a house fire in Northeast Baltimore that killed a grandmother and four of her grandchildren last week, city firefighters will canvass the entire city on Sunday and install smoke alarms wherever they are needed.

"This creates an opportunity to interact with the public that we serve and more importantly install an early warning device (smoke alarm) in conjunction with a home evacuation plan to keep residents safe from the dangers of home fires," Chief Kevin Cartwright, a spokesman for the department, said in a statement.

The fire department urges anyone without a smoke alarm to call 311 — within two hours, firefighters will arrive and install a 10-year lithium tamper-resistant smoke alarm, the fire department said.
