b. Lubricants, fuel, coolant, and battery fluid may be present on external surfaces of the generator set or
its components due to leaks or normal operation. These fluids will absorb NBC agents. The preferred
method of decontamination is removal of these fluids using conventional decontamination methods in
accordance with FM 3-5.
c. Continued decontamination of external generator set surfaces with supertropical bleach
(STB)/decontaminating solution number 2 (DS2) will degrade clear plastic indicator coverings to a
point where reading indicators will become impossible. This problem will become more evident for
soldiers wearing protective masks. Therefore, the use of STB or DS2 decontaminates in these areas
should be minimized. Indicators and the CIM display screen should be decontaminated with warm
d. External surfaces of the control panel assembly that are marked with painted or stamped lettering will
not withstand repeated decontamination with STB or DS2 without degradation of this lettering. The
recommended method of decontamination for these areas is warm soapy water.
e. Areas that will entrap contaminants, making efficient decontamination extremely difficult, include the
following: space behind knobs and switches on the control panel, exposed heads of screws, areas
adjacent to and behind exposed wiring conduits, hinged areas of access doors, spaces behind externally
mounted equipment specification data plates, areas around external oil drain valve, retaining chains for
external receptacle covers, areas behind external receptacle covers, access door locking mechanisms,
recessed walls for access door handles, fuel caps, load output terminal board access door, NATO
SLAVE RECEPTACLE, frequency adjustment controls, areas around tie-down/lifting rings, crevices
around access doors, external screens covering ventilation areas, and areas adjacent to the external fuel
drain valve. Replacement of these items, if available, is the preferred method of decontamination.
Conventional decontamination methods should be used on these areas, while stressing the importance
of thoroughness and the probability of some degree of continuing contact and vapor hazard.
In an NBC contaminated environment, the generator set should be operated with all access doors
closed to reduce the effects of contamination.
g. The use of overhead shelters or chemical protective covers is recommended as an additional means of
protection against contamination in accordance with FM 3-5. When using covers, care should be taken
to provide adequate space for air flow and exhaust.
h. For additional NBC information, refer to FM 3-3 and FM 3-4.
OPERATION WHILE CONTAMINATED. The generator will operate in a normal manner when exposed
to nuclear, biological, or chemical (NBC) contamination. It is capable of being operated by personnel
wearing NBC clothing without special tools or support equipment. Refer to FM 3-3, FM 3-4, and FM 3-5.
OPERATION IN A HIGH ALTITUDE ELECTROMAGNETIC PULSE (HAEMP) ENVIRONMENT.
a. Hold AC CIRCUIT INTERRUPTER switch (15, Figure 2-8) in open position until CONTACTOR
POSITION on CIM display screen reads OPEN.
b. Place ENGINE CONTROL SWITCH (6) in OFF position.
c. Place MASTER SWITCH (12) in OFF position and wait approximately 10 seconds.
d. Restart and operate generator set in accordance with applicable normal procedures (refer to para 2.11).
