A sealing membrane assembly including a flange having a body with a through passage. A first sealing membrane defines a first flexible panel with a first axial sealed opening extending therethrough. The first axial sealed opening extends at an acute angle. A second sealing membrane defines a second flexible panel with a second axial sealed opening extending therethrough. The second axial sealed opening extends at an obtuse angle. The first and second sealing membranes are secured relative to the flange such that the first and second axial sealed openings crisscross one another and the first and second sealing membranes seal the through passage except through the first and second sealed openings.

A fire protection element contains a layered body for sealing passage openings in components, such as building components, through which lines are guided. A method can be used for producing the fire protection element and the fire protection element can be used for sealing passage openings and/or joints in components against fire and flue gases.

A fire protection element includes a mat of intumescent material, a reinforcing liner and ventilation holes. Furthermore, a fire protection wrap is used as a fire protection element of this type.

A combination seal connects a filter or an equipment component to a base. The combination seal includes a seal material and flecks or particles made of intumescent material interspersed within the seal material. The flecks or particles of intumescent material undergo a chemical change when exposed to flames or heat and expand to maintain seal effectiveness and longevity without compromise.

This invention relates to a fire collar (10) that includes a housing (11) having a bore that includes a first opening (13) and a second opening (18), said second opening being spaced from said first opening by at least one side wall (12), and wherein the fire collar further includes mounting means (14) for mounting said housing to a supporting structure, said mounting means being located adjacent said first opening. The fire collar also includes a layer of intumescent material (46) contained within the bore, adjacent the first opening, and supported in said bore adjacent the side wall. The fire collar also includes one or more torsion springs (48) which are operatively connected to the housing and wherein each spring includes a first leg (50) and a second leg (51). The second leg (51) is capable of movement between a first or non-operating position proximal to the layer of intumescent material and a second or operational position whereby said layer of intumescent material that is in contact with said second leg, either directly or indirectly, at least partially

Fire protection glazing made of two or more glass panes spaced apart from each other by a spacer. A fire protection material and the spacer are arranged in an intermediate space between the two glass panes. A secondary seal encloses the fire protection material and the spacer in the intermediate space. The secondary seal has a cooling fire protection property and is free of any intumescent fire protection property. Exclusively the fire protection material, the spacer, optionally having an optional spacer attachment for attaching the spacer to the glass pane, and the secondary seal can be arranged in the intermediate space between the two glass panes.

A system for storing a hazardous product including a housing unit having an interior volume and a door coupled to the housing unit configured to provide access to the interior volume. The system includes an electrical connection configured to transmit electricity into or out of the interior volume. The system further includes a ventilation system for directing gasses and heat produced during a thermal event out of the interior volume.

A safety cabinet can include an enclosure defining an interior compartment accessible through an opening. The safety cabinet includes an interior lighting system. The interior lighting system can include at least one of an illuminating light to enable viewing to cabinet contents and an ultraviolet light configured to disinfect the interior compartment of the safety cabinet. To provide electrical power to the interior lighting system, the safety cabinet includes an electrical connection disposed through the enclosure. The electrical connection can include at least one of a bulkhead connector and an intumescent socket.

An improved fire barrier assembly is disclosed for use between two structures, either in a compressive mode or a combination compression/shear mode. The assembly includes at least a single foam core, or two foam cores separated by a gap. At least one foam core includes an intumescent layer. An outer wrap of a fire-resistant fabric surrounds the foam core. The assembly is fastened to one surface of one structure.

A fire reactive barrier device for protecting a fire wall system penetrated by a pipe or a conduit. A cylindrical sleeve is closed around and encapsulates a portion of the pipe or conduit penetrating the wall system. A flange extends externally along the outside surface of the wall to fully cover a penetration from the pipe or conduit. An intumescent component located within the sleeve expands on exposure to elevated temperatures filling any gap or space in the wall created by the pipe or conduit melting. The intumescent component may also penetrate holes in the sleeve to further expand out into the interior wall space. A system for protecting a fire wall system penetrated by a pipe or a conduit employs a second fire reactive barrier device positional on the opposite side of the fire wall system.
