The windshields of a responding Henderson Fire Department vehicle were blown in, injuring the driver and firefighters with shattered glass. Several firefighters had to undergo treatment for respiratory irritation. [2], The PEPCON plant, located in Henderson, Nevada, 10 miles (16 km) from Las Vegas, was one of only two American producers of ammonium perchlorate ("AP"), an oxidizer used in solid propellant rocket boosters, including the Space Shuttle, military weapons (SLBMs launched from nuclear submarines), and non-weaponized rocket programs (Atlas, Patriot, etc.). Several theories have been advanced concerning the cause of the fire and explosions. A large portion of the Las Vegas Valley within a 10-mile (16 km) radius of the plant was affected, and several agencies activated disaster plans. [4] A large amount of AP remained on the ground after the incident and material was subsequently recovered and recycled within one year. [6] The two largest explosions produced seismic waves measuring 3.0 and 3.5 on the Richter scale. Over the past several months we have become increasingly aware of rising shipping costs and extended delivery times. It might seem impossible to you that all custom-written essays, research papers, speeches, book reviews, and other custom task completed by our writers are both of high quality and cheap.

[9] A windstorm had damaged a fiberglass structure and employees were using a welding torch to repair the steel frame. [9] The Clark County Fire Department (CCFD) in Clark County, Nevada, did not issue a formal report but did issue a two-page press release on July 15, 1988, describing what it believed to be the cause of the fire; this and other CCFD information was incorporated into a report by the United States Fire Administration (USFA). High-density polyethylene (HDPE) plastic and steel drums were used for in-process and additional storage at the time of the accident, as they had been for many years prior to the Challenger accident. SAVE FOR LATER (Wish List) Quick View.

I have been a nurse since 1997. Bulk 200 Micron Ammonium Perchlorate Oxidizer. [4], The USDOL report discounted this theory while relying upon eyewitness testimony and scientific burn tests. RCS Hydroxyl-terminated Polybutadiene (HTPB) resin premixed with 0.95% CAO-5 antioxidant and 2.38% HX-752 bonding agent. *Please select more than one item to compare 200 Micron Ammonium Perchlorate Oxidizer, 3. [6], USDOL reported that considerable evidence suggested that natural gas leaks were present in the plant. The driver of a heavily damaged vehicle coming away from the plant then advised the chief about the danger of subsequent larger explosions, which prompted the chief to turn around and head back toward his station. (WECCO). [3] The other producer, Kerr-McGee, was located less than 1.5 mi (2.4 km) away from the PEPCON facility, within the area that suffered some blast damage. This premix should be used for propellants that contain 400 micron or larger Ammonium Perchlorate, or whenever maximum propellant strength is desired. 0.455" diameter throat 1.250" diameter exit Weight = 85 grams Click here for drawing. [10] Much of the approximately 4,500 metric tons of AP either burned/decomposed in combination with a fuel or exploded, with the final detonation creating a crater 15 feet (4.6 m) deep and 200 feet (61 m) long in the eastern storage area. [6] Ammonium perchlorate manufactured for other United States government programs was not held at the PEPCON plant during this period. Similar results were also reported for the removal of Cd 2+ ions. Serving Research, Commercial, Educational& Government Customers Since 1995IT'S MOTOR BUILDING SEASON! The shock wave buffeted a Boeing 737 on final approach. On the other hand, SH-FA(S)-2 shows comparatively better abilities because it was shown to remove 82, 90, and 95% of the ions at the three flux rates, respectively, which are more than twice the sorption ability of the parent bare fibers. This premix should be used for propellants that contain 400 micron or larger Ammonium Perchlorate, or whenever maximum propellant strength is desired. 0.103" thick, Paper liner tube for 38mm Kosdon motors. Today, the Henderson site is a commercial development near the Valley Auto Mall which is home to several dealerships and a university. Dimensions: 1.298" O.D. [9] USDOL stated that sparks from such operations would not present enough energy to ignite ordinary combustibles in close proximity, let alone at distances of up to 70 feet (20 m) and concluded that "the possibility of welding and cutting operations as a source of ignition is considered very low, in the author's professional opinion". The Fire Chief of the City of Henderson, who was leaving the main fire station about 1.5 miles (2.4 km) north of the PEPCON facility, spotted the huge smoke column and immediately ordered his units to the scene. The explosions leveled the PEPCON plant and Kidd & Co marshmallow manufacturing facility. Footage of the explosion were shown in the disaster and survival-related documentary-reality television shows: 1988 explosion and fire at a Nevada chemical plant, The largest of the several explosions at the PEPCON plant.

[2], USDOL concluded that the initiation mode of the fire was undetermined. The United States Department of Labor (USDOL), working with the Division of Occupational Safety and Health (DOSH) issued a lengthy report on the accident that discounted the cause and origin findings of the CCFD. Damage within a 1.5-mile (2.4 km) radius was severe, including destroyed cars, damage to buildings and downed power lines.
