While on a trip to Manhattan, I heard Manhattan send units in the 9th Battalion to 5th between W47 and W48 for an electrical fire in a commercial building. Engines 54, 65 and 8, Ladders 4 and 2 responded. On arrival a small electrical fire was found in the garage of a commercial building. Ladder 4 extinguished the fire with a CO2 extinguisher and transmitted a 10-18 for the incident. I walked from the area of the hotel and arrived at the same time as the companies.
