Total Claims: 4
Claim 1
Independent Claim
98 words
A dispenser in combination with chamber means containing a flammable or explosive material, said dispenser comprising means defining a confined space associated with said chamber means and containing a pressurized thixotropically gelled fire suppressant, and thixotropically gelled fire suppressant comprising a thixotropically gelled suspension of fire suppressant powder pressurized by a gas selected from the group consisting of nitrogen and carbon dioxide, said means defining said confined space being constructed of a substance selected from the group consisting of breakable and meltable substances so as to allow discharge of said material when said substance is broken or melted.
