Commander's Responsibility.
a. COs must determine lighting requirements, since physical layout,
terrain, climatic conditions, etc., will vary with each post facility.
b. Lighting requirements depend on:
(1) Threat.
(2) Perimeter extremities.
(3) Surveillance capabilities.
(4) Available guard force.
c. Contingency planning is required.
This will ensure proper
functioning during hours of reduced visibility.
Emergencies and mobilization
alerts will also need to be covered.
5.
Planning Consideration.
Physical security personnel plan the most
effective use of protective lighting.
Therefore, numerous factors must be
considered that have a direct bearing on each case. The aid of the Corps of
Engineers should be sought. Also, information from manufacturers of lighting
equipment should be sought.
Compliance with FM 3-19.30, Physical Security,
and other applicable regulations, is a must.
a. Plan for the cleaning and replacement of lamps.
Include cost and
maintenance required and available.
b. Consider the use of photoelectric and mercury control or automatic
controls.
These are desirable in peacetime situations, but they are
undesirable when blackout is a possibility.
c. Local weather conditions could affect various types of lamps and
luminaries.
d. Fluctuating and erratic voltages in the primary power source could
cause problems.
e. Establish a burning-time record. The ledger should be kept based on
80 percent life expectancy. It should also include the following data:
(1) Type and wattage of lamp.
(2) Area, facility, or utility pole used.
(3) Date of insertion.
