New safety measures are being implemented citywide to prevent tragedies like the Belmont fire that happened nearly a year ago.

The 2017 blaze on Prospect Avenue killed 13 people. It was one of the deadliest fires in New York City history.

In response, a new set of standards will go into effect. Under the new law, all buildings must have posted notices reminding tenants to close their apartment doors if a fire breaks out.

Officials say it was an open door that helped fuel the flames in the Belmont fire, leaving some with no way to escape.

Additional measures also make it mandatory for landlords to provide stove covers to families with children under 6 years old. The FDNY says that the Belmont fire was caused by a 3-year-old playing with a stove.

Landlords will have to cover the cost of the stove covers. City leaders say it is an expense that building owners cannot put a price on. More than 1,000 stove covers are being donated by local businessman Jack Jaffa.

The new fire safety laws go into effect Thursday.
