[6] On July 30, 1997, an explosion at that plant killed one and injured four.[14]. I agree to conduct my rocket activities in compliance with all applicable laws and regulations to the best of my ability. ... (37 and 90 pounds) ... occurred solely in areas where aluminum econo bins or steel drums were utilized to store the product of nominal 200 micron size. I understand that the manufacture of rocket motors and rocket propellant may be an inherently dangerous activity. [9] At that time, the damaged areas had been disturbed and key evidence had been either displaced or removed from the site. Rated 5.00 out of 5 $ 2.00 Per Pound / 2 Pound Bags . [12][2], In 1991, the Nevada legislature passed the Chemical Catastrophe Prevention Act, which led to Nevada's Chemical Accident Prevention Program. Recognizing the danger posed by a fire that was beyond their firefighting capabilities, they made no attempt to approach or fight the fire.[4]. The disaster caused two fatalities, 372 injuries, and an estimated $100 million of damage. 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. Academia.edu is a platform for academics to share research papers. [2], USDOL concluded that the initiation mode of the fire was undetermined. 2-piece thermoset molded glass-phenolic "aerospike" nozzle designed to fit AeroTech 54mm RMS reloadable rocket motor hardware for research and experimental purposes. That gas line was shut off at about 1:00 p.m. by the gas company at a valve about a mile away. Roads in the area were clogged in both directions due to residents trying to leave and curious spectators headed toward the scene, creating a traffic jam that took over two hours to clear. Clark County units staged 1.5 miles (2.4 km) from the scene and assisted injured firefighters. The facility also had a 16-inch (41 cm) high-pressure gas transmission line running underneath it, carrying natural gas at 300 psi (2.1 MPa) gauge pressure. !RCS IS YOUR 2021 BALLS LAUNCH HEADQUARTERS!NOTICE: RCS will be a major sponsor of the Hamster Dance 10 contest during BALLS 29 at the Black Rock Desert in 2021. More than an hour after the first explosions, authorities concluded that the airborne products could be a respiratory irritant; it was not considered highly toxic, nor was the danger of further explosions estimated as high. [4], USDOL also reported that there was strong evidence of a natural gas fire prior to the second explosion at the northeast edge of the plant within a 6 ft × 200 ft (2 m × 61 m) narrow band of soft sand. 1-1/16" I.D. [9] The on-site investigation of the plant revealed the presence of carbonaceous deposits around the perimeter of the foundation of the batch dryer building. [6][12], After the incident, American Pacific Corporation changed the name of the perchlorate chemicals manufacturing subsidiary to PEPCON Production, Inc and within one year, to Western Electrochemical Co. [9] USFA reported that little fuel remained after that, causing the flame to diminish rapidly, except for a fireball that was supplied by the high-pressure natural gas line underneath the plant, which had been ruptured by one of the explosions. [4], At about 11:54, as he approached the site, the first of the two major explosions sent a shock wave that shattered the windows of his car and showered him and his passenger with glass. [6][7], In addition to the PEPCON and Kerr-McGee facilities, there was also a large marshmallow factory, Kidd & Company,[8] about 500 feet (150 m) away, and a gravel quarry in operation nearby (3,000 feet (900 m) to the west). 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. [4] The invoice for this pipe, which was installed in 1956, characterized it as "limited service". Since we cannot control the storage, transportation and use of our products, once sold we cannot assume any responsibility for product storage, transportation or usage. *Please select more than one item to compare [9] The first significant DOSH inspection did not occur until 33 days after the fire. This facility is now owned and operated by the Clark County School District Facilities Service Center. It stated that smoking, sparking of electrical equipment, or frictionally ignited gas are among the probable igniting sources.[9]. NOTICE: RCS will be a major sponsor of the Hamster Dance 10 contest during BALLS 29 at the Black Rock Desert in 2021. 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. [9], Both the USFA and USDOL reports noted that the flames spread to 55 US gal (210 L) plastic drums containing the product that were stored next to the building as employees tried in vain to put the fire out inside the building with water hoses.

I, the buyer, have read the notice above and agree to its terms. Authorities had considered expanding the evacuation zone to 10 miles (16 km), but the idea was dropped due to the new information, although a few cases of respiratory irritation were reported in a small community about 30 miles (50 km) downwind. If you've been using PAPI or Isonate 143-L you'll be amazed at the difference! Additional propellants and components will be added as time permits. 0.455" diameter throat 1.250" diameter exit Weight = 85 grams Click here for drawing. About four hours after the incident, hospitals were advised by the fire department that their disaster plans could be deactivated.[4]. [4], An investigation estimated that the larger explosion was equivalent to 0.25 kiloton of TNT, approximately the same yield of a tactical nuclear weapon. Click here for a Safety Data Sheet (SDS) for RCS Copper Chromite. Natural gas service to this WECCO facility is handled in a different manner (mostly above ground away from AP storage areas) than was the case at PEPCON. [6], USDOL reported that considerable evidence suggested that natural gas leaks were present in the plant. USDOL reported that at least one fire was burning in a barrel located at the west side of the southern portion of the building partition, which separated the batch dryer from the batch tanks in the process building. Today, the Henderson site is a commercial development near the Valley Auto Mall which is home to several dealerships and a university. Search results for Aluminium at Sigma-Aldrich.

[9], USFA reported that the fire continued to spread in the stacks of drums creating a large fireball and leading to the first of four explosions in the drum storage area. Over the past several months we have become increasingly aware of rising shipping costs and extended delivery times. [6] An estimated 4500 metric tons[4] of the finished product were stored at the facility at the time of the disaster. Due in large part to the COVID-19 pandemic, USPS, FedEx and many common carriers are experiencing unusually long delays and even longer delivery times. RCS Rocket Motor Components (RCS), Inc. products are sold "as-is" and no warranty, suitability or fitness for any particular application, either expressed or implied, is made regarding RCS products. [9] Furthermore, USDOL stated, the likelihood of transferring hot molten metal a distance of over 70 feet (20 m) through and around batch tanks to the batch dryer is considered extremely remote. I have or I will read Terry McCreary's book "Experimental Composite Propellant" prior to using RCS products and will follow the safety procedures prescribed therein. The damage reached a radius of up to 10 miles (16 km), including shattered windows, doors blown off their hinges, cracked windows and injuries from flying glass and debris. Potassium Perchlorate.
