1.3G VS 1.4G FIREWORKS AND WHAT IT ALL MEANS

We are frequently asked a question more than any other; ‘what is the difference between 1.4g and 1.3g fireworks?’ Now, this is where it begins to get a little more complex. Up until 2017, all fireworks in the UK were classified under British Standard (BS) and everyone learned over the years what each of the different classes included and meant in relation to pyrotechnics.

Under British Standards, there were two available to the general public; garden fireworks with a 5m safety distance and display fireworks with a 25m safety distance. Both garden fireworks and display fireworks could be classed as 1.3g or 1.4g consumer fireworks.

1.3g is the more hazardous and they will contain more explosive power than 1.4g fireworks – this can be up to 5 times more powerful.

You can always tell if a firework is 1.3G or 1.4G by the CLP on the firework itself:

1.3G Fireworks CLP begins with DANGER (See the example picture below)

1.4G Fireworks CLP begins with WARNING (See the example picture below)

CLP - 1.3G Fireworks and 1.4G Fireworks

Today, the new CE standards are EU wide but there are still certain products that despite being permitted under European Law, our Health and Safety Executive decided to maintain the ban on some old favorites like aerial shells, bangers, screech rockets and of course air bombs.

Under CE the new classes are:

F1 INDOOR FIREWORKS – THIS WOULD INCLUDE THE ICE FOUNTAIN
F2 GARDEN FIREWORKS WITH A 8 – 15 METRE SAFETY DISTANCE
F3 CONSUMER DISPLAY FIREWORKS – 25 METRE SAFETY DISTANCE
F4 PROFESSIONAL DISPLAY FIREWORKS – THESE CAN ONLY BE USED BY SPECIALLY TRAINED PROFESSIONALS

NEC (NET EXPLOSIVE CONTENT) – this indicates the amount of explosive content (the quality of the content is also important to remember) there is in a firework piece. For example, one of our most popular cakes weighs a total of 7.7 kilos but has a maximum explosive content of 1 kilo. Generally, the term NEC is used but some refer to it as NEM (NET EXPLOSIVE MASS) or NEQ (NET EXPLOSIVE QUANTITY).

Although it is not always as apparent as some may think if you check into some of last year’s products with the 1.4g label like the 90 shot Aquarius barrage from Black Cat fireworks which is pretty, loud and at 6 kilos not a lightweight and contains 0.8 kilos of flash powder but is still classified as requiring a 25m safety distance because it is over 500g in NEC. However, when it comes to rockets, there is a huge difference and we would recommend 1.3g for decent effect rockets.

Today, due mainly to the changes implemented, the maximum NEC on any single barrage is 1 kilo but this rule does not apply to compound cakes which are viewed as a number of smaller cakes which are fused together.

If you are in doubt or need any assistance, please do not hesitate to get in touch as we will be only too happy to help.

Dr Thrust

Dr. Thrust by Epic Fireworks.

The 25 shot 1.3G range of fireworks is exceptional, perhaps the most popular barrage is the Dr Thrust.

Epic Fireworks - Dr Thrust

This firework begins with quick fired loud purple and blue mines which compliment the high bursting peonies, overlapping with strobing crackles and green glitter. Ending in large silver fizzing UFO’s, which break into large silver peonies.

Make Some Noise

This year Craigy G decided to create his very own mascaletta….(basically a mascletà is a concussive, daytime explosive display, akin to a “fireworks” display but focused on auditory effects, not visual)…

Craigy decided to use 60 x Thunder King Barrages – each barrage fires 25 shots !

So let’s do the maths:

(60 x thunderking cakes) x 25 shots = 1500 shots… BOOM :)
