Islandia is an unincorporated community and former city in Miami-Dade County, Florida, United States. It is located in the upper Florida Keys on the islands of Elliott Key and other nearby keys, such as Totten Key. It was the only municipality in the Florida Keys not located in neighboring Monroe County. The population was 18 at the 2010 Census. Most residents of the city were National Park Service employees.
Key Biscayne is an island village in Miami-Dade County, Florida, United States. The village is part of the Miami metropolitan area of South Florida. The population was 14,809 at the 2020 census, up from 12,344 in 2010.
Biscayne National Park is an American national park located south of Miami, Florida in Miami-Dade County. The park preserves Biscayne Bay and its offshore barrier reefs. Ninety-five percent of the park is water, and the shore of the bay is the location of an extensive mangrove forest. The park covers 172,971 acres and includes Elliott Key, the park's largest island and northernmost of the true Florida Keys, formed from fossilized coral reef. The islands farther north in the park are transitional islands of coral and sand. The offshore portion of the park includes the northernmost region of the Florida Reef, one of the largest coral reefs in the world.
A safety valve is a valve that acts as a fail-safe. An example of safety valve is a pressure relief valve (PRV), which automatically releases a substance from a boiler, pressure vessel, or other system, when the pressure or temperature exceeds preset limits. Pilot-operated relief valves are a specialized type of pressure safety valve. A leak tight, lower cost, single emergency use option would be a rupture disk.
Biscayne Bay is a lagoon with characteristics of an estuary located on the Atlantic coast of South Florida. The northern end of the lagoon is surrounded by the densely developed heart of the Miami metropolitan area while the southern end is largely undeveloped with a large portion of the lagoon included in Biscayne National Park.
Key Biscayne is an island located in Miami-Dade County, Florida, located between the Atlantic Ocean and Biscayne Bay. It is the southernmost of the barrier islands along the Atlantic coast of Florida, and lies south of Miami Beach and southeast of Miami. The key is connected to Miami via the Rickenbacker Causeway, originally built in 1947.
A double check valve or double check assembly (DCA) is a backflow prevention device designed to protect water supplies from contamination. It is different from the two-way check valves used in air brake systems on heavy trucks which select from the highest pressure source.
The Siebe Gorman Salvus is a light oxygen rebreather for industrial use or in shallow diving. Its duration on a filling is 30 to 40 minutes. It was very common in Britain during World War II and for a long time afterwards. Underwater the Salvus is very compact and can be used where a diver with a bigger breathing set cannot get in, such as inside cockpits of ditched aircraft. It was made by Siebe Gorman & Company, LTD in London, England. It was designed in the early 1900s.
A piping and instrumentation diagram is a detailed diagram in the process industry which shows the piping and process equipment together with the instrumentation and control devices.
An Atmospheric Vacuum Breaker (AVB) is a backflow prevention device used in plumbing to prevent backflow of non-potable liquids into the drinking water system.
A needle valve is a type of valve with a small port and a threaded, needle-shaped plunger. It allows precise regulation of flow, although it is generally only capable of relatively low flow rates.
Elliott Key is the northernmost of the true Florida Keys, and the largest key north of Key Largo. It is located entirely within Biscayne National Park, in Miami-Dade County, Florida, east of Homestead, Florida. It is bordered by the Atlantic Ocean to the east, Biscayne Bay to the west, Sands Key to the north, and Old Rhodes Key to the south. Adams Key is just west of the southern end of Elliott Key. Elliott Key is about seven miles (11 km) long. Its maximum width is about 2,500 feet (760 m) near the north end, and its average width is less than 2,000 feet (610 m). The higher elevations on the island range from 6 to 8 feet above sea level and occur generally along an unimproved road that runs longitudinally through the center of the island. The average elevation is about 3 feet (0.91 m) above sea level. The key is accessible only by boat. Elliott Key has a National Park Service campground, but is otherwise uninhabited.
Biscayne may refer to:
The Florida White House was an informal name for a compound in Key Biscayne, Florida, used by U.S. President Richard Nixon.
Soldier Key is an island in Biscayne National Park in Miami-Dade County, Florida. It is located between Biscayne Bay and the Atlantic Ocean, about three miles north of the Ragged Keys, five miles south of Cape Florida on Key Biscayne, seven-and-a-half miles east of the mainland and three miles west of Fowey Rocks. It lies on the Safety Valve, a sand bar that separates Biscayne Bay from the Atlantic Ocean and moderates storm surges into the bay.
A shutdown valve is an actuated valve designed to stop the flow of a hazardous fluid upon the detection of a dangerous event. This provides protection against possible harm to people, equipment or the environment. Shutdown valves form part of a safety instrumented system. The process of providing automated safety protection upon the detection of a hazardous event is called functional safety.
A refueling Fast Fill System allows speedy and safe refueling for many types of equipment. This includes mining, heavy construction, busses and railroad. Most larger earthmoving and mining vehicles with diesel fuel tanks over 150 US gallons (570 L) are equipped with a refueling Fast Fill System. These refueling Fast Fill Systems utilize an automatic shut off fuel nozzle, receiver and level control device. Refueling Fast Fill Systems operate by connection of a fill nozzle to the vehicle's fuel tank and with a source mounted pump that delivers fuel into the tank at rates up to 150 US gallons (570 L) per minute.
The Scott Air-Pak SCBA is an open-circuit, self-contained breathing apparatus designed to meet the National Fire Protection Association (NFPA) Standard 1981. All components, excluding the air cylinder, were designed and manufactured by Scott Safety. Formerly a division of Tyco International, Ltd., Scott Safety was sold to 3M in 2017.
Steam Link is a hardware and software product developed by Valve Corporation for streaming Steam content from a personal computer or Steam Machine wirelessly to a mobile device or other monitor. Steam Link was originally released as a hardware device alongside the debut of Steam Machines in November 2015. Valve discontinued the Steam Link hardware device in November 2018, in favor of supporting its software-based Steam Link application for mobile devices and smart televisions, as well as providing Steam Link as a software package for the Raspberry Pi microcomputer.
The 2019 California power shutoffs, known as public safety power shutoff (PSPS) events, were massive preemptive power shutoffs that occurred in approximately 30 counties in Northern California and several areas in Southern California from October 9 to November 1, 2019, and on November 20, 2019, by Pacific Gas and Electric Company (PG&E), Southern California Edison (SCE), and San Diego Gas & Electric (SDG&E). The power shutoffs were an attempt to prevent wildfires from being started by electrical equipment during strong and dry winds. The shutoffs initially affected around 800,000 customer accounts, or about 2.5 million people, but expanded to cause over 3 million people to lose utility-provided electrical power by late October as more utility companies from around the state also did preemptive power shutoffs.
