I just received this email "Irrespective of the weight of the model rocket fuel,(less than 100grs) it has a practical application and therefore will require a HSE’s manufactures license. 

You will therefore be required to contact the HSE Explosives Inspectorate at Bootle to make the necessary arrangements.  There will then be a requirement to have the rocket fuel classified.  It maybe, that the formula has already attracted a UN Classification.  Once Classified, the model rocket motor may or may not be subject to an explosives certificate."

So that means i now need a HSE Explosive inspector to judge whether i need a Certificate or not?.

What does the inspector look for? And does he mark via a scoring system? 

I will only be making 100g and using it on the day, I won't be keeping it.

Also, if there is any advice you could give me on what to expect during a visit, that would be great

Oh and where do i find the contact details for an inspector?

Many regards

OK.

 

You are correct you can effectively make a 100gram (fuel weight) rocket motor with rocket candy without the need for any form of licence for experimental testing purposes. There are no listed ingredients or explosives involved.

 

The issue could be, where are you going to fly it?

 

The rocket motor would be considered an unclassified explosive and hence can only be transported by road to a place of testing with the prior approval of the HSE.

 

Nope you can't add any dye to rocket candy to make coloured smoke. It unfortunately burns to hot, which destroys the dye.

Yeah i'm only looking to make 100g at a time, at least this means i don't need to acquire a license.

Just for knowledge sake, when would it be necessary to obtain a license, or would it only be needed if i was going to make over 100g of fuel.

The rocket i made is no more thn 6 inches long and 2 inches wide. I am launching it from my back garden, and will be pointing it towards unused fields. I do have a neighbor but i respect that and will only launch the rocket after i have spoken to them and let them know if they don't mind the noise. 

I luckily live in the countryside in a small village, so i'm not close to a main road, and 60  miles away from the closest airport.

So i should be ok without a license with all this in mind?

Sorry to repeat, i just want to make sure i do everything above board

Oh and do you know of any way i can color the smoke? or isn't it possible due to the heat.

Regards!

Strange, i just read the COER certificate and could find anywhere stating that i would need one when it comes to Pyrotechnics, neither could i find Potassium nitrate on the list.

I've emailed my county police department that handle Explosive and firearms, and hope they can clarify this. As a few people have said this is for Pyrotechnic use and not for explosive use.

As per my last post as far as I know you would need a certificate to make the explosive as it is not on schedule 2. Then not keep the mixture but instead make the rocket motor which would likely then be "1.4G  pyrotechnic article" until you were ready to do your experiment (fire the device)

Oh right, thanks. Where do i obtain a certificate?

Regards

Oh right, so that means i'm legally allowed to keep 100g or less in a secure place?
