ST1DinOH Posted February 20, 2008 Posted February 20, 2008 below is the latest report from china, concerning the feb 14th wharehouse explosion at the sanshui port. in this latest "release" there's a line that i'll highlight in bold for everyone that is confusing the hell out of me. i'm hoping you guys can awnser the question. Update from Cindy!!! 1. Sanshui port has been closed by Foshan city for all export of all fireworks. The State Council Work Safety Committee issued an article on 15th Feb for all fireworks-related safety and inspection authorities stating that Sanshui was found to be storing 1.1G (12” shells) fireworks and articles with high explosive content in 1.4G warehouses. Note: 2 out of 20 of the warehouses in Sanshui were permitted to store 1.1G. The Committee instructed all authorities in all provinces to carry out major inspections and tighten future inspections including warehousing, production, export safety inspection, and transportation.2. Nansha announced today that they will continue to accept fireworks B UT only 1.4G. Absolu tely no exceptions and NO 1.3G and 1.1G.3. China Shipping has announced that they will no longer accept display shells, fireworks containing red strobe or blue strobe, and packaging that has strike surface (for example on match-head cracker boxes) Whilst the opening of Nansha is small relieve for 1.4G shipments, the impact on 1.3G shipment (especially shells) will be far greater. At this time, only B eihai and Shanghai will accept 1.3G. However, since China Shipping was the only company accepting 1.3G from Shanghai , the only port that will accept 1.3G now is B eihai. There are now only two shipping companies that will accept 1.3G (Maersk and Zim). The IFA (International Fireworks Association) issued the following statement today, which you can find at http://www.infofireworks.com/News/Ne...s.asp?id=15386 (in Chinese) – roughly translated and only include points we did not mention above: * Liuyang Government with the support of Hunan Province CIQ, has decided to inspect all containers during loading. This will ensure Nansha port’s safety. Liuyang Government and the IFA will strong work together for a solution to the transportation problem. Guangdong Hua Dau port may be a substitute for Sanshui port. On 19th Feb, Liuyang Government and IFA will go to Shanghai to meet with respective fireworks transport companies to discuss this incident.* On 22nd Feb, IFA will go to B eijing to meet with port authorities, and experts to discuss safety and transportation.* In order to protect the export and shipment of fireworks from China , IFA urges all fireworks enterprises to be more stringent on product safety and at the same time, follow all rules and regulations such as proper UN classification of fireworks and packaging according to the IMDG code. We support the view of the IFA and believe that the fireworks industry must now work together to safeguard the future of fireworks production and shipment from China, by ensuring that all fireworks are properly classified and shipped according to IMDG code. As for shipment, we have warehouses in B eihai, Nansha and Liuyang, so we are in a good position to handle shipments in the next 6 months. However, as inspections on export will be tightened, shipments will be delayed due to the process of preparing CIQ certification for all items. With Sanshui closed, it is most likely that B eihai, Nansha and Shanghai will be over capacity, so containers will be delayed as a result. We expect to see this get worst in about 2-3 weeks time as factories are just returning to work this week and some don’t start work until early March. As always, if you have any questions, please feel free to ask and we will try our best to answer them. RegardsCindy whats with fireworks containing red strobe or blue strobe,??? i tried to awnser this question on my own but what i came up with doesn't exactly make sense. i know there are issues with magnesium and ammonium perchlorate causing spontaneous combustion... but thats all strobes not specificly red or blue right? and "Copper sulfate can not be used in formulas using ammonium perchlorate to produce a blue strobe." because the copper sulfate absorbs moisture and then can cause problems with the magnesium and ammonium perchlorate... but blue can be made without copper sulfate and nothing i've found so far is specific to red or blue stars only anyone care to shed some light on this subject. i figure you guys are the only people i know smart enough to awnser this correctly.
Frozentech Posted February 20, 2008 Posted February 20, 2008 whats with fireworks containing red strobe or blue strobe,???Well maybe the other strobe comps from China use Barium nitrate instead of Ammonium perchlorate ? What I want to know... what is the comp for the Blue strobe ??? Anyone have a decent blue strobe STAR comp ? I have *none*, I don't have my copy of the Wizard's Formulary with me either. P.S. I don't mean the silicone blue strobe rocket fuel, just a strobe star, stability and storage are factors.

I have *none*, I don't have my copy of the Wizard's Formulary with me either. yeah there was a specific warning on the PFP database where i got the warnings from that talked about copper sulfate, but i know there are pleanty of other ways to get blue without copper sulfate, just unsure if they work for strobes.
Mumbles Posted February 20, 2008 Posted February 20, 2008 Blue Strobes are a rather esoteric mix. They more or less don't follow the standard strobe formulas. Copper metal powder seems to be the secret ingredient. There are some formulas in one of the pyrotechnica issues by Jennings-White. Luckily for us, Skylighter has lifted a few of these formulas out for us. http://www.skylighter.com/fireworks/how-to...works-stars.asp
Frozentech Posted February 21, 2008 Posted February 21, 2008 OK, UTFSE, I know... Found a reference for blue strobe stars, it's Pyrotechnica XIV, my copy is a home, so I gotta wait... Also, Skylighter had an article on them. Finally get to use some GN. [edit] doh ! Mumbles beat me to it.
