What type of fire extinguisher is required as a minimum in an assisted living facility?

In an assisted living facility, the required minimum type of fire extinguisher is rated at 2A-10-BC. This rating provides a classification that indicates the extinguisher is suitable for fighting both Class A fires, which involve ordinary combustibles such as wood and paper, and Class B and C fires involving flammable liquids and electrical equipment respectively.

The "2A" rating indicates a capacity for extinguishing a specific type and size of fire, suitable for a typical environment like an assisted living facility where residents may use various materials in their everyday activities. The "10-BC" portion denotes the extinguishing capability for flammable liquids and electrical fires, which is critical in settings where there may be various appliances and equipment.

The other options might have higher ratings or different combinations, but they do not meet the minimum requirement effectively, as they may not adequately address the range of potential fire hazards typical in assisted living facilities. Thus, the 2A-10-BC extinguisher is the most balanced option for ensuring safety in an assisted living setting.
