I have a manufacturing plant in Mexico that makes Smoke Detectors that have Lithium Batteries. We had in incident where one of the Lithium Batteries ignited/internally combust. Would this be considered a CLASS A or B type fire for Extinguisher location placement? From a Extinguisher classification C (electronics would be suitible) but an ABC would be ideal to cover multiple potential issues.
The extinguisher was 71 feet away which fall into a Class A Hazard placement.
Looking for your input.
