**Work Plan History Information:** (List any lessons learned accidents
from this job, tips from previous jobs)

+-----------------------------------------------------------------------+
| The installation will be in an abandoned drift of the LaFarge mine in |
| North Aurora Illinois. There are no lights or electrical power        |
| available. Portable lighting will be supplied but limited in nature.  |
| There is potential for falling rock from the ribs or top of the drift |
| hard hats should be worn at all times. The floor is uneven with rocks |
| and debris around; safety shoes with ankle protection should be worn  |
| at all times. There is also the possibility of water or mud that can  |
| make footing hazardous. Care must be taken to observer where you are  |
| walking. There are also significant changes in floor elevations more  |
| than 20 feet in places. Do not climb berms and stay away from blocked |
| areas and locations that are posted with traffic cones or signs.      |
|                                                                       |
| The mine does meet Federal air standards. There is still dust and     |
| particulate matter in the air. Dust masks while not required are a    |
| good idea. There are noise sources that vary from time to time ear    |
| protections should be available.                                      |
|                                                                       |
| There will be six (6) concrete pedestals built to get HLS sensors to  |
| same level. These will be sona tube forms filled with concrete. The   |
| pedestals will be on the floor 100 to 120 feet apart and on the order |
| of 12 inches high. The concrete will be mixed at the site by hand.    |
| Care needs to be taken to avoid chemical burns from concrete and back |
| strains.                                                              |
