Here’s another marking you may have seen on fireworks:

1.4G

Unlike F1, F2, F3 and F4, this isn’t telling you whether a firework is a consumer or professional-use product.

It’s part of the dangerous-goods classification system used when explosives are transported.

The 1 tells us the product belongs to Class 1 – Explosives.

The .4 refers to the hazard division.

Division 1.4 covers explosives where, in transport terms, an accidental ignition or initiation presents only a small/localised hazard rather than the more significant hazards associated with some other Class 1 divisions.

And the G is the compatibility group associated with pyrotechnic articles.

You’ll see 1.4G marked on many boxes of fireworks.

So does 1.4G mean that the firework itself is small?

Not necessarily.

One important thing to understand is that the transport classification relates to the product as classified and packaged for transport.

That’s why two fireworks which look quite similar when fired may have different transport classifications.

So next time you see 1.4G printed on a fireworks carton, you’ll know there’s much more behind those four characters than you might think!
