Locate and repair all leaks. <br /> • Phone and computer system —when restoring energy to the facility, priority shall <br /> be given to the phone and computer systems before the rest of the building. <br /> • Power should be restored slowly to prevent damage from power surges. If any <br /> breaker trips immediately upon restore shut it dawn and check entire circuit <br /> before attempting to repower breaker. <br /> 14 <br />
