Hey All,

I’ve been looking for what folks consider minimum safe distances. (yes lots’o searching) Reloadable shells come with documentation of 40ft, many cakes say “get far away” and NFPA recommends 122.5 feet (70 foot per inch x 1.75….but that is 1.3 flash etc)

I want to have a safe distance but also don’t want to view *all* my 1.4 products from 150 ft away. I’d like to stage my field with fountains, and other small items etc...closer ….but how close

Let me give you a scenario and tell me what you think.

2,000 x 2,000 foot open solid ground area
1.4 legal only (no 1.3, no overloads, etc)
No wind
Each item/rack fired one at a time
Each item/rack properly staked/secured

What is the minimum distance for *your* audience for each item individually? (Remember ONLY 1.4 consumer stuff)


1) Firecrackers (your # here )
2) 200g fountain (your # here)
3) 500g fountain (your # here)
4) 48 shoot pearls (your # here)
5) Mines – (assume critical acclaims) (your # here)
6) Roman candle rack (your # here)
7) 200g cake (assume low shot count) (your # here)
8) 500g cake (assume low shot count) (your # here)
9) Premium canister/ball shells (assume in HDPE straight up rack) (your # here)
10) NOAB (your # here)
11) Pre loaded tubes (reaper type etc) (your # here)
12) Rocket rack (your # here)

Quote 1 – 12 and drop your number in the section (the formating should stay) and then add your commentary!

Thanks!

Much of what you're asking about is currently being discussed in the following thread already.

I would put fountains and mines 25 feet away from people and the rest of the stuff 125 feet away.

When doing Arial stuff, I shoot about 200ft from the crowd. It adds a bit to the '70ft per inch rule'. It also makes the 'view' more enjoyable. If you are too close, you'll constantly be looking high up at the fireworks. Looking about 30-40 degrees in the air is more enjoyable in my mind.

i like to be far enough back that i can see the lower level effects and the higher level effects with out having to look up and down the entire show. i would say 300 -350 ft.

1) Firecrackers (75 )
2) 200g fountain (50)
3) 500g fountain (50)
4) 48 shoot pearls (100)
5) Mines – (assume critical acclaims) (200)
6) Roman candle rack (200)
7) 200g cake (assume low shot count) (200)
8) 500g cake (assume low shot count) (200)
9) Premium canister/ball shells (assume in HDPE straight up rack) (200-300)
10) NOAB (200-300)
11) Pre loaded tubes (reaper type etc) (200-300)
12) Rocket rack (400)



I would use these numbers for both 0336 and 0431/2 1.4 material. I can understand the OP's thought on not being so far away but everything looks better from 150 to 300 feet. If you think it is too far away, just shoot multiples of the same item in a front, it looks great...

i have a berm that everything is shot behind...regardless, my numbers are...

1) Firecrackers (50 )
2) 200g fountain (30)
3) 500g fountain (30)
4) 48 shoot pearls (50)
5) Mines – (assume critical acclaims) (150)
6) Roman candle rack (75)
7) 200g cake (assume low shot count) (150)
8) 500g cake (assume low shot count) (150)
9) Premium canister/ball shells (assume in HDPE straight up rack) (175) (with plywood in front of it)
10) NOAB (175) (with plywood in front of it
11) Pre loaded tubes (reaper type etc) (175) with plywood in front of it
12) Rocket rack (400) (i dont have enough room for this...these can be super unpredictable, and there's just no area around me large enough to control the fallout, this to me is a good number for 1.4 rocket's)
