If you’ve ever looked closely at the label on a firework, you may have noticed something like F1, F2, F3 or F4.

But what do those letters and numbers actually mean?

Fireworks are divided into different categories depending on their intended use and level of hazard.

🟢 F1 – Very Low Hazard

These are small fireworks with a very low hazard and negligible noise level. Some F1 products are designed to be used in confined areas, including indoors.

Think of things at the very small end of the pyrotechnic world.

🟡 F2 – Low Hazard

F2 fireworks are designed for outdoor use in relatively confined areas.

These are the type of fireworks many people associate with smaller garden displays.

🟠 F3 – Medium Hazard

F3 fireworks are designed for outdoor use in large open areas.

They can produce significantly bigger effects and generally require considerably more space than F2 products.

🔴 F4 – High Hazard / Professional Fireworks

F4 fireworks are specifically intended for use only by people with specialist knowledge.

These are commonly referred to as professional fireworks and include products designed for professional display work.

So when you see a professional display filling a large area of sky, the fireworks being used can be very different from those intended for a small garden display.

And the category is only part of the story…

Next Wednesday we’ll take a closer look at F3 and F4.

🎆 Make the Moment Spectacular.
