Contrails and/or D.B.A Trojan Motors may or may not be required to obtain EX numbers for their propellant grains. If like some other hybrids, the Contrails/Trojan fuel grains are simple unboosted polymers such as PVC, ABS, Polyethylene, Polypropolyene, or other plastic polymers, then EX numbers are not necessary because polymers of this type are not explosives. If the fuel grain is a composite with an oxidizer or other burn rate enhancing additives, a DOT certified classification may be and probably is required. If the classification test data results in a 4.1 flamable solids clasification, then an EX number is not required. If the classification test data reveals the fuel grain is a class 1 material, then the data must be submitted to DOT for an EX number assignment before the motors can be sold and/or shipped.

I have to believe that TRA TMT would not certify Contrail motors without insuring that Contrails/Trojan manufacturing and motor designs meet the necessary NFPA 1125 Sections 4.2 permitting and Section 7.5 design requirements, so there must be a paper trail somewhere.

We analyzed at least one fuel composition using ion spectrometry and did not detect oxidizers or energetic compounds. The initial question does not concern the fuel however but the thermite composition supplied in the packaging as an igniter. The packaging at the time was labeled ORM-D and after inquiring, it was determined that the manufacturer had made this determination without application to the DOT. The determination was based on interpretation of a exemption cited by the manufacturer. The AHJ had a different interpretation regarding shipping classifications for thermite compositions.

Is the thermite composition shipped in a mixed state or as separate components?

Mixed and assembled with two resistor initiators in a plastic bag.

Your guess is as good as mine

Probably the same reason that they had "concerns" about Warp-9.


you mean the document exploded at LDRS? ;)

Just to clarify, this is the DOT documentation for APCP, correct?

You like that, huh? :D

Sounds like the same issue Quickburst is having. According to the current interpretations of the BATFE regulations, you need a LEMP to manufacturer igniters, and according to DOT you need to have an approved classification performed on the material. It the classification indicates that it is a class 1 article, it also needs a DOT EX number.

Ah yes, the qualification test to determine if it falls out of class 1. Test results anyone? Even if a test was done why was the package labeled ORM-D and not 4.1? As for your UPCO reference, I just happen to have a box full and it's not thermite, it's APCP. See attached and notice the labeling. Oh and BTW, those rods (grains) are over 64.5 grams. How they got 4.1 is beyond me seeing how it burns. That one slipped through the cracks in more ways than one.

I was aware of that, it was one of the exhibits we submitted to the DOT is support of a reclassification of AeroTech APCP to 4.1 (which they initially promised they would grant).

In the past the document was always written with the grantees listed in alphabetical order.
So when Aerotech went away AMW was the next in line.
So when "Centuri Corporation" became "Estes-Cox Corporation", AMW should have been "next in line" for DOT-E 7887? ;)
 
For the record!!

AMW Inc. did NOT in any way, thru any means, have anything to do with the fact that the DOT changed the Grantee on 10996..

As per the norm, (sadly) suspicious attitudes still prevail..

Take it up with DOT

AMW is a signatory to SP-7887. Hell, even my company is a signatory to SP-7887 (see attachment). It ain't that difficult and it ain't anything special if you can legally ship hazmat and have the appropriate Federal, State and local permits.

Go here to find who's on what special permit. https://hazmatonline.phmsa.dot.gov/SPSearch/

What point are you trying to make?

I believe you, Paul. I'm sorry if I inferred otherwise.

I am curious though, if AMW was "next in line" for 10996, why not for 7887?

I know, talk to the DOT...

And your point is...?
 
U.S. Government:

"We're sorry, your 'explosives' are not explosives, but for the purposes of justifying our jobs they will be classified as 'explosives'. While one division of the federal government may believe that your 'explosives' are not explosives and may in fact treat them as a non-explosive, our division firmly feels that your non-explosive really is an 'explosive'. So for the purposes of dealing with the United States, your 'explosives' are not explosives except when we say they are 'explosives' although it has been shown that these 'explosives' do not explode. We hope this clarifies things.

Thank you,
JBGT"

I think my point was clear enough.
