- Time constraint of working over a 3-day weekend
- All equipment had to be cleaned and wrapped in plastic for moving through the hospital to the fourth floor work area
- All equipment had to be staged inside the small work area with shared workers
- Workers were required to wipe down all equipment prior and to and following each work time to minimize dust in hospital
- Workers were required to wear hospital gowns, caps, face masks, and booties while moving through the hospital to minimize the spread of dust and germs
- Minimize amount of dust, germs, and noise while moving through the hospital as well as the work area.
- Work in tight quarters with three-men crew and work equipment
- Shot blast safely in small work areas.
- Operate circular saw and chipping hammer safely in small work area.
