A man making butane hash oil caused a fire that burned himself and damaged five vehicles parked in a Tigard lot Tuesday, according to Tualatin Valley Fire & Rescue.

The fire occurred about 2:15 p.m., at a TriMet park-and-ride near Southwest Pacific Highway and 74th Avenue. No one else was injured and witnesses reported an explosion before spotting flames, said Alisa Cour, a Tualatin Valley Fire & Rescue spokeswoman.

Cour said the fire was apparently caused accidentally and she did not know if the man was inside or outside his car when the incident occurred. The man was taken to Legacy Emanuel Medical Center for treatment. The man's identity and condition have not been released.

The flames destroyed two vehicles and damaged three others. Tigard police said Wednesday that the incident is still under investigation and no citations have been issued.
