Eliminating bus fires
We worked very well together and it has resulted in a simpler internal profile and an outer profile that just clips in place
Fire can often spread rapidly on a bus, and there is little time to escape. Under Swedish fire regulations all buses weighing over 10 tonnes must therefore be fitted with a permanent extinguisher.
A few years ago the Swedish company Dafo Brand developed an aluminium fire extinguisher container for heavy vehicles such as buses, trucks and forestry machines, in collaboration with Sapa.
In contrast to normal handheld fire extinguishers, the container, which is filled with a liquid extinguisher medium, can be laid flat. It takes up little space and is easy to service and install. The large aluminium profile for the container was complex and has to meet strict dimensional requirements.
“Sapa contacted us and said they would like to develop it,” says Kaj Dahlström, technical designer with Dafo Brand. “We worked very well together and it has resulted in a simpler internal profile and an outer profile that just clips in place.”
