A crash on the Bolte Bridge on Wednesday 26th May afternoon spilled fuel and a small quantity of a radioactive substance on the road.
The accident forced the closure of the bridge for several hours while MFB firefighters, working with officials from the Department of Health, secured the situation, cleaned up the radioactive material, emptied the vehicle's damaged LPG tank and ensured the road was safe to reopen.
Department of Health officials said the radioactive substance was used in medical procedures and posed no danger to the public.
"Even though it was a small amount of material it had to be treated with caution," said an MFB spokesperson.
