Know how to respond during a power failure. Be sure to keep a flashlight handy in case the lights go out. Remember the following:
Contact the business owner or manager to find out if you should stay open.
Make sure you know how to record sales and secure cash.
Make sure all vault doors are secure.
Turn off the circuit breakers. This will help avoid a power surge when the power comes back on. You may want to leave on the breakers for the lights, so you will know when the power comes back on.
Be extra careful after dark. You will probably need to close the business and lock the front and rear doors.
After the power comes back on, check to make sure all electrical equipment is on and working properly.
