Baltimore fire officials revised a new dispatching policy Monday amid an investigation into why an engine on the scene of a house fire on Friday was turned away. The city began looking into the matter after audio of firefighters being ordered to leave the scene circulated on the internet. According to audio of fire department communications posted on YouTube under the name Mack Flickerson, Engine 31 from Waverly responded to a house fire at 7:17 p.m. on Friday. The incident involved “reports of a fire on a second-floor kids’ bedroom” with “smoke showing on the second floor,” according to the audio.
