Abstract: A waste water filtration system filters polluted waste water from various waste water sources including fire sprinkler systems and fire hydrants. The system may be connected by a pipe or hose to a fire sprinkle system riser or stand pipe. The filtering system includes a stainer to capture large particles, a fine particle filter to capture small particles, and may include a chemically selective sponge to capture, for example, oil, and destroy bacteria, when necessary. A switch senses the presence of liquid and turns on a pump when required to advances liquid through the fine particle filter. The filtering system preferably allows compliance with NFPA Standards, California State Fire Marshal's and the California Water Resources Board Best Management Practices (BMP) for maintaining fire sprinkler systems, and Federal Clean Water laws, Federal Coastal Zone laws, and local city ordinances for releasing liquids into storm drains.

Abstract: A waste water filtration system filters polluted waste water from various waste water sources including fire sprinkler systems and fire hydrants. The system includes a clear flexible hose connecting a female swivel connection on, for example, a Fire Department Connection (FDC) to a mobile filtering system. The clear hose allows the observation of a waste water flow from the waste water source to ensure that a complete flushing has been accomplished. The filtering system includes a stainer to capture large particles, a filter to capture small particles, and a chemically selective sponge to capture, for example, oil, and destroy bacteria. The filtering system allows compliance with NFPA Standards, California State Fire Marshal's “Title 19 Regulations for maintaining fire sprinkler systems, and Federal Clean Water laws, Federal Coastal Zone laws, and local city ordinances for releasing liquids into storm drains.

Abstract: A waste water filtration system filters polluted waste water from various waste water sources including fire sprinkler systems and fire hydrants. The system includes a sight tube which connects to a female swivel connection on, for example, a Fire Department Connection (FDC). A flexible hose connects the sight tube to a mobile filtering system. The sight tube allows the observation of a waste water flow from the waste water source to ensure that a complete flushing has been accomplished. The filtering system includes a stainer to capture large particles, a filter to capture small particles, and a chemically selective sponge to capture, for example, oil, and destroy bacteria. The filtering system allows compliance with NFPA Standards, California State Fire Marshal's “Title 19 Regulations for maintaining fire sprinkler systems, and Federal Clean Water laws, Federal Coastal Zone laws, and local city ordinances for releasing liquids into storm drains.

Abstract: A waste water containment, filtration, and transportation system captures polluted waste water from various waste water sources including fire sprinkler systems and fire hydrants. The system includes a sight tube which connects to a female swivel connection on, for example, a Fire Department Connection (FDC). A flexible hose connects the sight tube to a mobile holding tank. The sight tube allows the observation of a waste water flow from the fire sprinkler system or fire hydrant to ensure that a complete flushing has been accomplished. A rod attached to an end of the sight tube holds a clapper in the FDC open during testing. The waste water is held in the mobile holding tank for later disposal. The containment and transportation system allows compliance with NFPA Standards, California State Fire Marshal's “Title 19 Regulations, the Federal Clean Water laws, the Federal Coastal Zone laws, as well as local city ordinances.

Abstract: An emergency fuel shutoff device for interrupting the flow of gas or other fuel to a burner in the event of a malfunction or fire. The device uses a normally closed spring loaded fuel valve which is held open by tension along a cable. The cable has several fusible links along its length. If any of the fusible links melt, the tension in the chain is released and the spring loaded fuel valve closes, shutting off the flow of fuel to the burner. Preferably the device also has a manual shut-off station which has a pull ring which also releases the tension in the cable shutting off the flow of fuel. When the tension in the cable is released a horn or strobe light provides an audible and a visible signal that the fuel valve has been closed. The horn and light are preferably powered by standby batteries.
