A manual activation system includes a pulley movable between an inactive position and an active position, a tension member wrapped about the pulley, the tension member having a tensile force acting on the pulley, and at least one arm rotatably mounted adjacent to the pulley. The at least one arm has a groove configured to cooperate with a portion of the pulley to selectively oppose the tensile force.

Sectional fire protection systems and methods for the protection of an attic space are provided. A fluid control thermal detection device is located above a ceiling base and one or more open fluid distribution devices are disposed, spaced and connected to the fluid control thermal detection device for receipt of firefighting fluid from the fluid control thermal detection device to protect the attic space with a desired fluid density and total system flow demand.

An apparatus is disclosed for extinguishing a stovetop fire over a stovetop having a first burner, the apparatus including a container detachably mountable to a microwave positioned above the stove top. A supply of fire suppressant material is retained within the container. A heat responsive actuator is disposed on the container. When the container is mounted to the microwave over the first burner, and the fire actuates the heat responsive actuator, at least a portion of the supply of fire suppressant material falls from the container toward the first burner.

System and methods using automatic fire protection sprinklers to provide ceiling-only fire protection of rack storage. The systems and methods provide for hydraulic and system parameters that include a hydraulic design area based upon five to no more than twelve hydraulically most remote fire protection sprinklers with a prescribed hybrid minimum design pressure.

A mattress and mattress cover assembly, comprising a mattress component, wherein the mattress component includes a first foam layer having a top side and a bottom side; and a second foam layer, wherein the second foam layer is attached to and extends widthwise and lengthwise across the bottom side of the first foam layer; and a covering completely enclosing the mattress component, wherein the covering includes at least one liquid-resistant layer, wherein the at least one liquid-resistant layer is an outer layer comprising elastic fibers; and at least one fire-retardant layer either attached to or formed integrally with the at least one liquid-resistant layer, wherein the at least one fire-retardant layer is an inner layer comprising fire-retardant fibers.

Systems and methods of the invention relate to managing an inventory of items within a storage container. A storage container can house one or more items for distribution among one or more users such as, for instance, employees. The storage container discussed herein provides authentication of a user, tracking of the inventory each user removes or returns, video/image capture of user during access of the storage container, wireless tracking of items housed within the storage container, among others. The storage container can provide flame retardant protection and/or electrical isolation to one or more items located within the storage container.

System and methods to provide ceiling-only suppression fire protection of up to fifty feet (50 ft.) of rack storage of cartoned unexpanded plastic commodities and less hazardous commodities, such as for example, Class 1, Class 2, Class 3, Class 4 and/or combinations thereof beneath a ceiling having a maximum ceiling height up to fifty-five feet (55 ft.). The systems and methods provide for hydraulic and system parameters that include a hydraulic design area based upon five to no more than twelve hydraulically most remote sprinklers spaced at a preferred sprinkler-to-sprinkler spacing of eight to ten feet (8-10 ft.) coupled to two to four branch lines tied to a common cross main supply pipe of firefighting fluid.

A system and method for reducing the risk of fire in an oxygen delivery system. The system may include an oxygen delivery device with a controller in communication with a flow control valve to control a flow of oxygen through a tubing from an oxygen source to a patient interface. The controller may be programmed to close the flow control valve for a predetermined time period at a predetermined time interval to cause a periodic oxygen pause, the periodic oxygen pause to remove oxygen that may serve as an oxidizer when a fire is present inside at least one of the patient interface and the tubing.
