11/5/26 Brooklyn 3rd Alarm Box 2634

[den114]

No cause as of yet; 2 batteries were discovered, and the building was illegally converted to hold more people.

FC transmitted a 10-41,1. Probably due to the amount of fire on arrival or unknown cause.

My grandson works for the "U.L." =Underwriters Laboratory just south of Philadelphia in addition to being a Professional Firefighter. U.L. has just completed a series of tests and experiments with Lithium Batteries and has learned much, about what causes runaway reactions. But the extinguishment of runaway fires or actions to prevent exposed battery's from become involved is still a major problem. I heard about a fire chief in the Midwest who had a fire in a Lithium Battery Energy Storage Facility. Thew Chief had his firefighters pour bags of dry concrete over the batteries, and this worked to contain the fire. I told my grandson about this idea, and he presented this concept to his bosses a U.L., NO answer from any authorities on if this tactic is valid. I will keep you posted when I get more information about this major often deadly problem.

Is this a class 3 or class 4 building? Size up was given as class 3, it's a wood/row frame though no?

In the old NYC Bldg. Code, these were most likely wood frame CLASS 4. (Usually row frames with a common cockloft. There may have been some brick nogging in the wall in the cockloft area)|

In today's Bldg. Code they could be any one of the following -

• Class II-B: Protected wood joist
• Class II-C: Unprotected wood joist
• Class II-D: Protected wood frame
