Peak global ozone depletion is expected to occur during the next several years, and the stratospheric ozone layer is expected to recover in about 50 years in response to international actions under the Montreal Protocol and its amendments and adjustments.2 The early phaseout of halon production accounts for at least 15% of the protection provider! under the Montreal Protocol.3 The phaseout of halon production took effect January 1, 1994, with little disruption because the fire protection community had established global information networks and coordinated halon banks.

.l° To assess the safety of a fire extinguishing agent for use in a total flooding system, EPA analysts examine the actual design concentration as NFPA defines it,' ~ i.e., the cup burner extinction concentration plus 20%, or in some cases the actual large-scale testing design concentration, and compare this value to levels at which cardiotoxic effects have been observed. The situation differs for streaming agents (i.e., chemicals applied to localized fires, usually by being propelled from an extinguisher)

Conditions for the appropriate use of inert gases with limited oxygen have been evaluated by special medical panels, and EPA has also solicited guidance from OSHA on conditions of use, since OSHA will ultimately determine the proper use of all fire suppressant systems. Workshops and panels have been formed to analyze issues concerning powdered aerosols and water mists.
