SAN DIEGO - No matter where you live in San Diego County, you've most likely seen the unbelievable video or experienced firsthand how wildfires know no boundaries.

Wildfires are especially dangerous inland, where dry brush and canyon terrain butt right up against homes. Homeowners in those high-risk areas are urged to take extra precautions to keep their homes and families safe.

"What you have here is thinned out vegetation you can tell its green," said Cal Fire's Capt. Mike Mohler as he pointed out into a canyon.

10News asked Mohler to inspect the home of Rancho San Diego resident Dick Hausam to look for potential fire hazards.

"I've watched the smoke from here," said Hausam, pointing out into the East County.

"Well, this house technically is threatened because embers can travel for miles," Mohler said.

Mohler and Hausam talked about the importance of closing windows during wildfires and how important it is to have screens from the dryer vents to attic vents.

They also looked at the trees all around Hausam's house.

"It's trimmed, it's maintained, so this really isn't a threat," Mohler said as he pointed up to Hausam's palm trees. "You've done your due diligence."

What Hausam needs to do, in event of a wildfire, is move his barbecue's propane tank that's against the house.

"Take those propane tanks, wood piles, anything that's up against the house that may catch fire take that and move it 5 to 10 feet off your house," Mohler said.

"Anything like that, I never thought of," added Hausam.

But all in all, Hausam learned he's on the right track and received an A, by school standards.  

To Hausam, a former principal, that's a grade he likes to hear.
