Open toolEvery dangerous-goods shipment, prepared and under control
We think dangerous goods should travel by the rules, and as safely as the work allows. So we built a set of tools for everyone who handles them — tunnel restrictions, the transport document, UN number search, the 1.1.3.6 calculator and a practice test — and made them free, as our contribution to a safer industry.
When a load is documented and controlled, emergency services know what they're dealing with the moment something goes wrong. Fewer surprises on the road mean fewer serious accidents — and that matters to us more than a paywall ever could.
New to dangerous goods and unsure where to start? We'll walk you through it, prepare your documentation and get you properly set up.
