Safety Memo #18 Earthquake Safety on the Workplaces

Date: July 5, 2019

To: ACI PROJECT DIVISION
Earthquake Safety on the Workplaces

Yesterday on July 4, 2019, a 6.4 magnitude earthquake hit Kern County; from over a hundred miles away, seismic activity was
felt.

**All project supervisors should inspect their jobsites prior to the start of their work. A seismic shift could have effected
scaffolding, elevators, ladder systems, etc. Even if the impact of the jolt was never felt, it does not mean that somethings did
not shift.

A 6.4 magnitude earthquake is considerable and with each point the magnitude rises the effect is 100 times greater. For
example, a 6.5 is 100 times greater than a 6.4
In addition, the large opening earthquake followed by hundreds of aftershocks could be the precursor to a larger quake.

Please be prepared in the event of a seismic emergency. Evacuation plans and safe rendezvous points should be established
and followed on site for after an earthquake has finished.

We want everyone to be safe on and off the workplaces.

What to Do During an Earthquake:

If the ground starts shaking beneath your feet follow these three steps:
1. Drop to the ground
2. Take cover by getting under a sturdy desk or table.
3. Hold on to it until the shaking stops.

If there isn't a table or desk near you, drop to the ground in an inside corner of the building and cover your head and neck
with your hands and arms. Do not try to run to another room just to get under a table.

If you are outdoors, move to a clear area if you can safely do so; avoid power lines, trees, signs, buildings, vehicles, and other
hazards.

If you are driving a car, pull over to the side of the road, stop and set the parking brake. Avoid overpasses, bridges, power
lines, signs, and other hazards. Stay inside the vehicle until the shaking is over. If a power line falls on the car, stay inside until
a trained person removes the wire.
