Great video. Thanks for these.
So if you can't get the size of the charge info, how do you know when you are past the legal transport or storage limit?

None of us have to worry about legal limits for transport, it is a huge number. For users of consumer fireworks the rules regarding storage the quantities in the Explosives Regs are given in gross amounts not NEQ so it's not a problem. We can store 10 kg gross weight in a dwelling and 1000 Kg in a storage unit. Very good question though, good for you.  SHOP Fireworks FX.com |

Should mention that it is 300 g + or - 10% but not over . So most upper end cakes top off at 270 g to 280 g . Also the bursts are limited to 8 g + or - 10 % but not over . So in most cases the bursts are 7g to 7.75g per tube .

Just a slight correction, the 8 g limit is for "small effects" which are considered secondary effects in addition to the main effect. Could be miniature star bursts, tourbillions, whistles etc. So the max charge weight per tube is whatever the manufacturer can get into a 22 mm tube safely with any secondary effects in that tube limited to a max of 8 grams. Love poring over the minutia of fireworks construction 🤪 SHOP Fireworks FX.com |

Also commonly known as cakes in Canada is the category Battery/Combination under the Authorization Criteria for Consumer and Display Fireworks. A Battery/Combination is limited to 7 tubes. The specifications are based upon the articles (Roman candles, mines, fountains, flares or ground whistles) that are in the Battery/Combination. For instance a Mine is allowed to have Total pyrotechnic composition: no more than 40 g effect composition + no more than 10 g lift charge or If there is more than 1 effect in the mine, the pyrotechnic composition of individual effects + total lift charge must not exceed 25 g. There is also no tube size limitation for mines.
So if you were wondering about the really good 7 shot cakes that have become available in the last couple of years this is why they are allowed.

We can store 10 kg gross weight in a dwelling and 1000 Kg in a storage unit. Very good question though, good for you. I'm not sure that I understand this. Would not the gross weight be far more than the NEQ? Even so, 10kg (10,000g) divided by 300g (max cake load) eguals 33.33 cakes. How is this not a problem? What time frame is considered storage? (hours, days, weeks, months, years?) I'm not sure how many of the pieces that I buy for May 24 & Canada Day are anywhere near 300g, but I buy way more than 33.33 cakes plus many single shots. In a quick search to find out what NEQ stood for I found a thing that says that the ATF considers NEQ to be 25% of gross when no other weights are listed. I would assume that ERD would be similar. That completely changes the math to 10kg divided by 1200g, which equals 8.33. Please elaborate and/or correct my math/thought process. |

Yes, gross weight is considerably more than NEQ. The limits for transport is huge and that is not a problem, but you're right about the limits for storing in dwellings could be a problem. ERD has low limits for any kind of storage of any material in a dwelling as that is where people live, eat and sleep. Possibly families, children, seniors etc. A dwelling could be a detached home but could also be a condo or apartment so they are not too fussy with us storing boxes and boxes of cakes under the bed. Now let's face it, the SWAT team is not going to knock down someone's door in the middle of the night because they have 4 boxes of consumer fireworks somewhere on the premises, but where I would worry about it is when it comes to insurance. If there is a fire and it becomes known that fireworks were involved all the insurance investigator has to do is ask for copies of invoices from the fireworks vendor to determine how much was purchased and if is above legal limits than the insurance company can deny the claim. Not a good place to be if someone is facing the total loss of their home and contents. Since we do not know the NEQ of any firework than we have to go by gross weight, so 10 Kg of cakes is not very many as there is a lot of clay in the base. There is no easy answer to storing your stash legally if you have no place to store other than your dwelling, just pray there isn't a fire and an insurance claim. And I lump myself into that position too as there are times I have several boxes of fireworks at home overnight for one reason or another. SHOP Fireworks FX.com |

As far as I know the time frame that is considered storage is not written in any regulation or criteria document. That is because there is no time frame. Once it is not attended it is in storage.
The only time frame I am aware of is during transportation. While working on getting containers of fireworks moving out of ocean ports on trains I asked 3 different inspectors including the previous Chief inspector about this. All 3 gave the answer longer than 24 hours it is considered storage.
This is not the same answer for 10kg of fireworks in a dwelling or up to 1000kg in a storage unit as it is based on a transportation situation. The container of fireworks in this case is also in an access controlled port with people working there. During transportation fireworks must be attended (means to be constantly monitored by a person). Once fireworks are no longer attended they must be in storage. One past explosives inspector who was also a TDG inspector told me that he walked around a truck 3 times and if no one talked to him about it he considered the fireworks unattended. There are other limited situations where explosives in transportation may be unattended but none apply to a user of consumer fireworks.
So in your house or a storage unit once you leave the fireworks are in storage.

Thanks guys Now the silly part about regulations and ambiguity... My brother has literally not left his house since march. We could all just "not store" our stashes at his place.  Knowing him, he will charge a fee. The big problem would be having any stash left after his boys were done with it. Oh yeah...please read and take all of this post with the lightness that is intended. Did you know that the "Ontario Green Book" (Health and Safety Regulations) has no specified weight for maximum safe limit for a person to lift or carry. It is whatever the individual is comfortable with. It was really hard for me to complain to upper management when none of my co-workers would assist in unloading containers from China where there are simply no regulations. Does this help explain my tongue in cheekiness? I'm not a big fan of ambiguous regulations. Nowhere is a speed limit posted as whatever speed you are comfortable with. BTW... I don't argue a speeding ticket if I get one. I was speeding. |

There is also no tube size limitation for mines. So if you were wondering about the really good 7 shot cakes that have become available in the last couple of years this is why they are allowed. Not sure I’m understanding this... Are you saying that some of these newer 7 tube cakes we’re seeing can pack up to 25g of composition per tube because they fall under this “battery/combination” category (and can therefore technically pack the same amount of composition as individual shots like bombshells/Brazilian shells)? I mean technically some of these 7 tubes also have a mine effect that goes up with it... did I just call out a loophole here? Also, (going back to one of my earliest questions in the forum) I guess even with this enhanced limit the nishiki effect is still out of reach for us in Canada since the composition limit is too small and won’t allow for big enough stars? |

The Mine with multiple effects in the Battery/Combination has the same amount of composition as bombshells and Brazilian shells (25 Grams) but the design and arrangement of the effects is different. 7 shot cakes have the biggest shots of any multishot firework allowed in Canada.
As for the Nishiki effect as close as would be possible is probably BEM Wizard for effect size and duration. In general if you look at the duration on all the new 7 shot cakes the stars burn longer because they are bigger.
