(19) Fixed extinguishing system means a permanently installed system that either extinguishes or controls a fire at the location of the system.
(20) Flame resistance is the property of materials, or combinations of component materials, to retard ignition and restrict the spread of flame.
(21) Foam means a stable aggregation of small bubbles which flow freely over a burning liquid surface and form a coherent blanket which seals combustible vapors and thereby extinguishes the fire.
(22) Gaseous agent is a fire extinguishing agent which is in the gaseous state at normal room temperature and pressure. It has low viscosity, can expand or contract with changes in pressure and temperature, and has the ability to diffuse readily and to distribute itself uniformly throughout an enclosure.
(23) Halon 1211 means a colorless, faintly sweet smelling, electrically nonconductive liquefied gas (chemical formula CBrC1F2) which is a medium for extinguishing fires by inhibiting the chemical chain reaction of fuel and oxygen. It is also known as bromochlorodifluoromethane.
