SAFETY PLAN

• October 2003, Review Committee - Recommendation #3“Third is the need for more formal safety planning. The circumstances of the installation in 2004 and 2005 present a significant risk of accident. Early, detailed, safety planning is needed to ensure adequate personnel training and full-time coverage by safety officers on all shifts for the duration of the installation. With appropriate advance planning, training, and staffing, the work can be conducted safely.”
