Many of the injured had been struck by flying glass when windows were shattered. 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. *Please select more than one item to compare 100 gram jar. At the same time, these same carriers have also announced shipping rate increases. [4] Eyewitness testimony and a video, which was filmed by Dennis Todd and began after the first detonation, as well as other resources indicated there were five high-order detonations: one north of the batch dryer, one in the storage area south of the administration building, two on the loading dock and the final largest detonation in the eastern storage area, where the gas line burned after the detonations occurred. 75 & 98mm Slow White Lightning™ propellant grains, Altus Metrum line of rocket avionics and related products added to the "Avionics" category, 8221™ (E6 propellant) 24mm propellant grain, 54mm filament-wound carbon fiber motor casings, Water-slide and self adhesive multiple logo decal sheets, 29mm x 5.79" long thin wall fiberglass casing, 29mm x 8.00" long thin wall fiberglass casing, 29mm x 9.06" long thin wall fiberglass casing, 29mm x 12.00" long thin wall fiberglass casing, 38mm x 7.98" long thin wall fiberglass casing, 38mm x 14.03" long thin wall fiberglass casing, 54mm x 14.10" long thin wall fiberglass casing, 54mm Warp-9™ propellant grain cast in plastic tube, Modified MDI Isocyanate Curative 1 Gallon, Hydroxyl-terminated Polybutadiene Resin w/CAO-5 Antioxidant & HX-752 Bonding Agent 1/2 Gallon. I … The USFA report stated that this activity caused a fire that spread rapidly in the fiberglass material, accelerated by nearby ammonium perchlorate residue. This premix should be used for propellants that contain 400 micron or larger Ammonium Perchlorate, or whenever maximum propellant strength is desired. The windshields of a responding Henderson Fire Department vehicle were blown in, injuring the driver and firefighters with shattered glass. [9] The extremely rapid fire spread in the process building and subsequent growth to other buildings was primarily due to the highly combustible fiberglass reinforced siding panels and close spacing of adjacent buildings.

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. At the same time, these same carriers have also announced shipping rate increases. Crews in protective clothing headed to the scene to clean up, a slow process due to leaking tanks of anhydrous ammonia and residue from acids and other products. About 75 people escaped successfully, but two were killed in the last two larger explosions: Roy Westerfield, PEPCON's controller, who stayed behind to call the CCFD; and Bruce Halker, the plant manager, who stood near his car when the first major detonation occurred. 200 Micron Ammonium Perchlorate Oxidizer, 3. NOTICE: New Restrictions on AP Purchases Due to increased Department of Homeland Security (DHS) concerns, we have placed new restrictions on all Ammonium Perchlorate (AP) purchases.
