The tower has 25 lightning rods on its roof to prevent lightning damage. cite web | title = Space Needle Fun Facts | publisher = Space Needle Official Site | url = | accessdate = ] It is built to withstand winds of up to 200 mph (320 km/h) and earthquakes up to 9.5 magnitude fix|link=Wikipedia:Contents|text=citation needed (which would protect the structure against an earthquake as powerful as the 1700 Cascadia earthquake). When it was completed it was the tallest structure west of the Mississippi River. The Space Needle is 605 feet (184 m) high and 138 feet (42 m) wide at its widest point and weighs 9,550 tons. Located at the Seattle Center, it was built for the 1962 World's Fair, during which time nearly 20,000 people a day used the elevators, with over 2.3 million visitors in all for the World Fair. The Space Needle (often called just "the Needle" by locals) is a tower in Seattle, Washington, and is a major landmark of the Pacific Northwest region of the United States and a symbol of Seattle.

ISO standard 7886-1 controlled drugs dead space needle syringe.Ĭopyright © 2021 Association of Veterinary Anaesthetists and American College of Veterinary Anesthesia and Analgesia. When calculating the amount of drug lost due to dead space, both that of the syringe and needle used should be considered. The dead space of syringes differs between brands, and some do not meet the ISO standard. Needle dead space was 0.05 mL for 23 and 21 gauge, and 0.07 mL for 18 gauge, similar in order of magnitude to syringe dead space. ![]() For the 20, 30, 60 mL syringes the dead space was less than 0.2 mL. For 5 mL syringes four of five brands, and for 10 mL syringes one of five brands failed to comply with the ISO the dead space was greater than 0.075 and 0.1 mL, respectively. Syringe dead space for 1 and 2.5 mL was less than 0.07 mL. Mean dead space was calculated for each syringe volume and needle gauge. A Mettler electronic balance was used for the measurements. The dead space of the needles was estimated using a similar technique: each needle was attached to a 1 mL syringe of known dead space. The difference in mass between the two measurements was calculated and converted to a volume based on the density of water. Syringe dead space was estimated by weighing each syringe, drawing up and expelling its rated volume of water for injection and re-weighing the syringe. ![]() ![]() Syringes of five brands and seven volumes: 1, 2.5, 5, 10, 20, 30, and 60 mL, 10 of each, 10 1 mL low dead space syringes and 10 23, 21 and 18 gauge needles were analysed. To measure the dead space of various syringe volumes and brands and a range of needles gauges commonly used in clinical practice, and to compare the results to the International Organization for Standardization (ISO) standard 7886-1:2018.
