MAKE YOUR HOUSE A SAFE SANCTUARY

-

When the Big One hits — we’re talking about a massive earthquake that causes towers and bridges to collapse and turns the region into chaos — you’ll find yourself in ultimate survival mode. Your house, or those around you, may now be smoking debris. People will die, emergency services will be overwhelme­d and power will probably be out for days.

Shelters will eventually open and government­al aid will arrive to ease the day-to-day struggle, but don’t count on that happening right away.

Your best chances of ensuring that you and your family emerge relatively unscathed after a devastatin­g earthquake that occurs while you’re at home is to make sure your house is a sanctuary of safety. Here’s what you can do to have the best chance of that happening:

 Secure your house to its foundation with anchor bolts, if it hasn’t already been done. It will help prevent the structure from sliding off its foundation.

 Install extra wooden sheeting along the home’s cripple walls — those short walls in the crawl space between the foundation and floor. That will also help keep the house on its foundation.  If you live in a soft-story house, meaning the first floor is not well reinforced and will collapse in a big temblor, it’s recommende­d to spend the considerab­le amount of money it will take to have it retrofitte­d. Or if you don’t own the building, talk to the landlord about this. In some cases, the retrofit is required by local law.

 For a mobile home, install braces or a tie-down system underneath to keep your house from collapsing during the shaking. The gas shut-off valve is parallel to the pipe, usually 6 to 8 inches above the ground. Use a 12-inch or larger adjustable wrench to give the valve a quarter turn, so that it is crosswise to the pipe.
