When the shaking starts, drop, cover, and hold on. Protect your head and stay away from windows. Once the shaking stops, immediately check on staff and other people who may be in your facility. Treat anyone who may be injured. Also check electric and gas lines for damage. In some instances, earthquakes can set off fire alarms and sprinkler systems.
While aftershocks are possible, you will want to start cleanup and rebuilding as soon as possible to minimize disruption to your business. Check your facility for any damage. Look for structural damage and check power lines, gas lines, and plumbing. HD Supply has products that can help repair and restore your property after an earthquake.
