(Portland, OR)  --  Nearly half of all Portland Fire & Rescue firefighters were working on fires at the same time Monday night.  Two houses in the Brentwood-Darlington neighborhood were on fire requiring a second alarm to get more help.  A small fire was reported in the Powellhurst Gilbert neighborhood that only needed one truck.  Then a call came in for a fire at a residential care facility in the Eliot Neighborhood.  That fire was quickly put out.  No injuries were reported from any of the fires.  An investigation is ongoing into the cause of the fire that damaged two homes.  A total of five adults were displaced from the homes.
