straight from the words of jeff at MJG...
Hey, its Jeff from MJG. I signed up but it won't let me post to this topic for some reason. This new law will not effect Rocketry. It is only for people that install the igniter into the fireworks and transport them. Nothing will change with how you want your igniters.
as i suspected, its for what the fireworks industry refers to as "prematched" products. for an electronically fired fireworks show, many display companies will spend a few days ematching their products in anticipation of the show. this saves a lot of time (and labor dollars) during setup of a fireworks show. unfortunately, due to the friction sensitive nature of ematches in general, sometimes rough handling or anything that causes friction to be placed on the ematch, the product can ignite, and with 1.3g fireworks, the shell is lit within milliseconds (quickmatch).
there was an accident this year in North Carolina involving (reportedly) "prematched" product, in which several employees died and a few more were injured. this has been a growing concern in the industry for the past several years as a few accidents of this nature happen each fireworks season.
it looks like there will be seperate specs however for ematches designated for fireworks, or for rocketry application.
perhaps jeff could fill us in a bit more once he figures out how to post.
