Nonstructural Hazards

In an earthquake, injury and damage can result from the collapse of building elements that are not part of the wood frame structure. These elements are called nonstructural hazards and need to be properly braced to the structure, removed, or relocated.

Common nonstructural hazards are:

• Weak chimney--Weak chimneys may collapse and the bricks fall onto the roof or the ground.
• Tile roof--Heavy roof tiles may shake loose and tumble down.
• Unsecured water heater--Water heaters can topple and cause fires and water damage.
• Trees--Large, old, or leaning trees around your house may topple in an earthquake. Check for root rot or for large branches that are weak.
• Large glass areas--Large panes of glass can shatter into dangerous shards.
• Light fixtures--Light fixtures inadequately tied to the building's framing can fall or cause damage as they swing.
• Hanging plant--Hanging plants can also fall or damage nearby windows as they swing.
• Large, top-heavy furniture--Tall bookcases, cabinets, or other heavy furniture can topple and cause injuries and damage.
