Before an Incident

• Familiarize yourself with Aerospace outage procedures
• Consider buying a flashlight, especially if you are in a SCIF and will not have access to your phone flashlight

During an Incident

Aerospace buildings are equipped with emergency generators. In the event of power loss,
one elevator in each building will remain active on generator power. Employees, however, will
be advised to use the nearest stairwell. The generator will provide emergency lighting in the stairwells
and lighting on each floor. Power will also be provided to the building’s essential emergency and
life safety equipment such as the fire alarm panel, alarms, fire pumps, security system etc.

• Remain calm.
• Stay put until the emergency lights come on. When switching to the emergency generator, there
will be a delay of up to ten seconds between the power failure and the transfer of power to
the generator. During this time, locations without natural light sources will be in total darkness.
• Assist visitors and staff in your immediate area.
• Security will notify Facilities or SCC (after normal business hours).
• If you are in a dark area, proceed cautiously to an area that has emergency lights. Use a flashlight if you have one.
• If the elevator car stops between floors or doors do not open, use the emergency telephone in the elevator car to call for help. Do not attempt to exit the elevator.

Lab Teams:

– Shut down any laboratory equipment that could be hazardous if the
power suddenly returns

– Keep laboratory refrigerators and ultra-low freezers closed during the
outage

• If instructed to evacuate, proceed to the designated assembly areas.

*For extended outages, message(s) will be sent out to employees with
information and/or instructions

Other Utility Outages and/or Leaks

• If there is any other outage, such as water or a suspected leak (water, natural gas, etc.),
immediately notify the SCC.
• Follow instructions as provided by Security and management.

After an Incident

Aerospace will send communications to employees regarding return to normal operations. This may occur via AeroElert, PA system, or other.
