Cardboard at Events: Let's Talk Fire Safety

"What about fire safety?"

We hear this one a lot at Cardboard Mill.

And we get it. You're planning an event. You love the idea of sustainable cardboard installations. But then someone from OH&S raises the fire question, and suddenly everyone's nervous.

Here's the thing about cardboard and fire risk: it's not what you think.

The Reality of Cardboard and Fire

Cardboard needs to hit 250 degrees Celsius before it ignites.

That's not happening from ambient heat or a stray candle. That's "you're actively trying to set it on fire" territory.

To put that in perspective: that's hotter than boiling water (100°C), hotter than your oven on a low roast (150-180°C), and significantly hotter than any normal event environment will ever reach.

How Does Cardboard Compare to Other Materials?

Let's talk about plastic signage — the material cardboard often replaces at events.

Plastic ignites faster than cardboard, burns hotter, and releases toxic fumes when it does.

Cardboard? Burns slow. Easy to extinguish. No toxic smoke.

So if a worst-case scenario happens at your event, you're actually in a better position with cardboard than most materials already in your venue.

What About Venue Compliance?

We know that no matter how safe cardboard actually is, you still need to satisfy your venue's requirements.

That's why we provide full spec sheets for venue compliance — fire ratings, material certifications, whatever your OH&S team needs to tick the box.

Because we're not just here to tell you cardboard is safe. We're here to prove it with the documentation your stakeholders need to see.

The Bottom Line

The reality is this: cardboard isn't more dangerous than the other materials in your venue. It's just got a reputation it doesn't deserve.

Timber staging. Fabric draping. Foam core signage. All standard at events. All with their own fire characteristics.

Cardboard sits comfortably among them as a safe, practical choice — with the added bonus of being genuinely sustainable.

Ready to Talk Specs?

If fire safety's been holding you back from using cardboard builds at your event, let's have a conversation.

We can walk you through the technical details, provide the documentation you need, and help you make the case to your venue and stakeholders.

Because once you understand the facts, the fire safety question stops being a barrier — and starts being just another box to tick.
