I had a chat with Scott, who makes the Cobra system. As for now, SFI' s are out of the question due to capacity of only one per que. So I' ll use my regular igniters for the time beeing.

And after a good discussion on the subject, I have concluded that prefusing with shrouded igns in a warm cosy place, repacking them in the original cartons and taping them up is an acceptable risk. And hopefully within the regulations.

Thanks Mastrechief, would you have a copy or a link? It could be an interesting read, really.

 

As for cakes, fountain etc I agree, prefusing pose no "real" problem, at least when it comes to indution and static electicity.

Some articles come prefuses anyway, esp the indoor pyro stuff.

 

But as for pro fireworks, if yoy install the ignitor, it still is a fused article, and could be against regs. But as Cooperman writes, it might also not be...

 

If I understand my ADR/RID-regs properly, the reason you pack and label your pyrostuff is basically twofold.

 

The first is that your articles are protected from outside and inside shock, friction, heat and whatever you are carrying is sensitive about.

This is where installing a igniter with a shock or friction sensitive pyrogen comes into play. SFI's might be a my sloution to this. We'll see.

 

The second is labeling in case of an accident or fire, so that the EMS can identify your cargo and take the right precautions.

 

This is very crude summary, so please feel free to comment.

No. My bad.

The igniters are prewired to the mortars, not the shells.

Shells are transported in original boxes with UN-labels as they come from the importer.

 

Reading Coopermans alternative is interresting.

If prewired articles in original UN-labeled boxes are allowed, part of my problem is solved.

The reason I started this tread was to raise the discussion on how to do things safe AND workefficient.

 

And, I deem prewiring in a controlled environment a far better solution than wiring on site.

I am still however, conserned with sensitive igniters prewired to shells.

Martyn: Thanks for the link. I had a look at the SFI and sent away an email to Pyrosure.

I was not aware of this opprtunity, so we will run a test on these and see if they meet our needs.

 

If this is as good as they claim, prefusing the products ahead will save us some time and make tings easier.

It is of course also a matter of price, but I'll see what Pyrosure can come up With.

Martyn: Do you know the price for these in say thousands?

 

Edit: Did a search, and they are priced at around  65 US cents a pop, exl freight. That's for a case of 720 pieces.
