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.
What is Halon (1211 & 1301)?
