What is AFFF (foam)?
500
This rating indicates that the extinguisher is non-conductive and effective for 2 cubic feet of ordinary combustible materials burning, or 10 square feet of surface area fire for a liquid.
What is a 2A 10BC extinguisher?

What is requirement for protecting a flammable liquid hazard?
500
A certificate issued by the State Fire Marshals Office showing that the extinguisher has been serviced by a licensed professional within the past year.
What is a service tag?
500
Gaseous agents that inhibit the chemical reaction of the fire. They were banned from new production, except for military use, as of January 1, 1994, but reuse is still permitted. Hazards include asphyxiation, flying projectiles, and highly toxic decomposition products.
