The Santa Ana warehouse of the Red Hill Construction company, located at 1431 E St Andrew Place., caught fire on Thursday morning after rags soaked in a wood-staining chemical spontaneously combusted overnight, according to the O.C. Register.

Thirty Orange County Fire Authority firefighters arrived at the scene at 7:11 a.m., and extinguished the fire.  The fire caused $150K damage to the building and $200K damage to its contents.

Unfortunately the warehouse, several vehicles and most of the equipment inside was destroyed by the fire.  The building will also need a  new roof.

These types of fires are common.  The solution is to store the oily rags in a special waste bin that prevents spontaneous combustion.
