Various safety systems, including explosive containment, ventilation and filtering, fire protection, agent monitoring, and door monitoring. 

Several parameters must be considered when selecting a fire protection agent and system. These include their effectiveness, limitations, advantages, reliability, costs and whether the goal is fire control, suppression, or extinguishment.

The HRP values can also be reduced by increasing the heat of gasification and decreasing the heat of combustion by retaining the major fraction of the carbon atoms in the solid phase, a process defined as charring. Several passive fire protection agents are commercially available to enhance the charring characteristics of materials. 

The critical parameter that needs to be examined in the presence and absence of the passive fire protection agents is the ratio of PGP (smoke, CO, corrosive and toxic products) to HRP. The effectiveness of the passive fire protection agent would be reflected in the small values of the ratios at fire control, suppression, and/or extinguishment stage. 

Today, fire-protection halons are subject to international restrictions imposed by the Montreal Protocol on Substances that Deplete the Stratospheric Ozone Layer. Consequently, production of these fire protection agents has been phased out as of January 1,1994. New halon replacements are now available. See NFPA 2001, Clean Agent Fire Extinguishing Systems.
