A section of Old Cariboo Highway in Prince George, B.C., remains blocked off after a truck carrying a liquid corrosive material crashed early Friday morning.
Police say the crash involving a flatbed tractor trailer happened just after 6 a.m. PT.
The truck was carrying two large sacks of red phenol-formaldehyde resin, a corrosive chemical used as a plywood adhesive. One of the sacks ruptured, spilling on the truck and a nearby ditch.
The driver of the truck and an RCMP officer were treated in hospital for exposure to the chemical.
Officials are asking anyone who may have driven through the spill to head to the hospital immediately.
"From what I understand, there were some people who may have at least drove through it. So it may be on their cars so they may get exposed to it that way," said RCMP Cpl. Craig Douglass.
"It is not airborne exposure. It is simply direct contact. So anybody who may have done that this morning is urged to go to the hospital to get checked out to make sure they're okay."
A Hazmat team and the Prince George Fire Department are on scene cleaning up the thick, syrupy resin.
The Ministry of Environment says no waterways are affected, and there doesn't appear to be a threat to public safety.
Police say the clean up will likely take most of the day. The highway remains closed between Giscome and Johnson roads.
