A sealed and ventilated receptacle for storing equipment, such as firefighter turnout gear, includes a base, at least one sidewall extending from the base, and a top wall that covers the opposite end of the sidewall. A sealable door may be positioned on the sidewall to access the inside of the receptacle and to prevent any contaminants from exiting the receptacle. The receptacle may also include an intake fan and exhaust fan that are each connected to a duct for providing fresh air to and removing contaminated air from the inside of the receptacle. The receptacle may further include a temperature control unit for regulating the temperature inside of the receptacle. Additionally, a hook for hanging a firefighter coat, trousers, or other items may also be included on the inside of the receptacle.

A firefighter backpack assembly for transporting equipment for wildfire fighting includes a panel that is wearable on a user's back and a pair of shoulder straps each being coupled to the panel for wearing over a respective one of the user's shoulders. A tool bag is coupled to the panel to carry tools thereby facilitating hands-free transportation of the tools when the user wears the panel. A pair of belts is each coupled to the panel to secure a chainsaw to the panel thereby facilitating hands-free transportation of the chainsaw. A storage pouch is suspended from the tool bag to contain a fire shelter.

A strong unsolved need exists to provide people with breathable gases for inhaling instead of ambient air, when people live in areas, where the ambient air is polluted with toxic gases and particulate matters. The present invention solves this need by disclosing a breathing apparatus, a dispenser of breathable gases, and a distributor of breathable gases, for supplying breathable gases to people, exposed to polluted and contaminated outdoor and indoor ambient air.

Disclosed are methods and a safety system of a structure for an air parameter based automatic purging of breathable air within the safety system. In accordance therewith, an air analysis device is coupled within the safety system along an air flow path of the breathable air from the source thereof. The safety system has a fixed piping system installed within the structure for supply of the breathable air across the safety system. A sensor associated with the air analysis device senses a parameter of the breathable air within the safety system. In response to an alert signal indicative of the sensed parameter of the breathable air being outside a predetermined threshold value, a valve and/or a vacuum pump within the safety system automatically purges the safety system of at least a portion of the breathable air.

A safety system implemented within a structure includes a source of breathable air, and a fixed piping system to supply the breathable air from the source to each interior region of a number of interior regions across the structure. The fixed piping system is implemented in a ringed architecture including a first portion of the fixed piping system proximate the each interior region and a second portion thereof farther away from the each interior region. In accordance with the ringed architecture, the first portion and the second portion are implemented as a continuous ring with respect to the source of the breathable air such that, even during a compromise of a first sub-portion of the first portion, unaffected by the compromise, the breathable air continues to be supplied to a second sub-portion of the first portion by way of the second portion.

Disclosed are methods and a safety system of a structure for automatic switching between sources of breathable air within the safety system in accordance with air parameter based automatic purging of a compromised form thereof. The safety system has a fixed piping system installed within the structure for supply of the breathable air from a source across the safety system. In response to an alert signal indicative of a sensed parameter of the breathable air being outside a predetermined threshold value, a breathable air purging system within the safety system automatically purges the safety system of the breathable air, and a bypass controller device automatically switches to another source of the breathable air to ensure a continued supply of the breathable air via the fixed piping system of the safety system.
