Tank trailers used to haul flammable, corrosive, toxic and explosive goods can only run on public roads after passing tough safety checks, and they have to follow local traffic and safety rules strictly.
UNECE forms the basic international transport criteria. Cross-border transport needs ADR qualification and UN tank certification, which control vehicle structure, leakproof performance and pressure resistance. Every country also has its own local standards. The US follows 49 CFR, DOT and MC industry rules, and Canada applies TP14877 as well as CSA B620 regulations.
Transport companies need to check trailer structure, sealing parts and corrosion status regularly all through usage, so as to prevent safety incidents.
Safe dangerous goods transport needs eligible vehicles, complete documents, experienced workers and timely certificate renewal. Qualified tank trailers are marked with standard UN signs, and keep detailed service records to monitor
working conditions.
Drivers of these special vehicles must take professional training and hold valid permits before getting on duty. Annual overall inspections and regular tank checks are necessary to keep certificates valid. Any unqualified or expired trailers must be suspended from use. They can be put back into service only after full repairs and re-inspection. Solid daily management on devices, documents and staff is essential to guarantee safe and steady operation of dangerous goods tank trailers.
