CONTAMINATION AVOIDANCE COVER (CAC) DEPLOYMENT
If an NBC attack is expected, deploy the CAC as follows (see Figure 3):
1. Put the TWPS in Standby Shutdown without Draining Down (WP 0017) including shutting down
the Tactical Quiet Generator (TQG). If time does not permit a Standby Shutdown, press the
emergency stop button on the TWPS control panel and shut down the TQG.
2. MC-TWPS only: lower and secure the operator station roof.
3. A-TWPS only: remove the fabric wall.
4. Disconnect all external hoses (and heating ducts if used) from the TWPS.
5. Pack all items you wish to protect inside the TWPS as time permits.
6. A-TWPS only: install all flat rack panels, close and secure the top panel and the deck panel.
NOTE
For the A-TWPS, do not unfold the CAC over the back of the TWPS until the
operator has come down the folding steps and is on the ground.
7. Lay out the CAC on top of the TWPS and unfold it over the sides. Make sure the bottom edge of
the CAC reaches the bottom of the TWPS on all sides of the TWPS.
8. Neatly tuck the CAC in at the corners and fold the flaps around the corners.
9. Tie three CAC 3/8-in. x 60-ft. ropes all the way around the CAC; one around the top, one around
the middle, and one around the bottom.
10. If an NBC attack occurs, do not remove the cover. The cover and unit must be decontaminated
in accordance with FM 3-5 prior to removing the cover and using the unit.
