OSB Propane Forklift
   Received permission from the run coordinator for Chris to test run the propane forklift parked just outside the OSB rollup door.     

   At 16:32 (09:32) started the propane forklift. There was strong coupling into DARM around 20Hz to 80Hz, and a drop of about 5.5Mpc,while the forklift was running. The forklift was shutdown at 16:43 (09:43); DARM and the range returned to normal. 

   The conclusion: NO idling or running the propane forklift during Observing. 

   Will update the NOT Acceptable document to exclude operation of the propane forklift.
