Description of Driving Event:

After every launch, personnel are required to climb out and balance on the liquid hydrogen external tank vent line to remove blast covers. After launch, the vent line is covered with a mixture of solid rocket booster residue and sound suppression water, thus making it very dangerous to climb on the line to remove blast covers. The location under the vent line is a 20-foot unprotected drop. Personnel could fall and/or drop the heavy blast shield cover during the installation/removal process.
