3.0 HAZARD AND CONTROL ANALYSIS <br /> The following hazards were assessed to either exist, or have the potential to develop, during the <br /> performance of the project activities: <br /> HAZARDS <br /> � Q <br /> TASKS Z U CJ p 2 U w <br /> U o o zw o <br /> w � o o �- U <br /> as <br /> Geophysical Survey X X <br /> Drilling(Direct Push) X X X X X <br /> Soil Sampling(Direct Push) X X X X X <br /> 3.1 Mechanical Hazards <br /> Type(s)/Source: <br /> • Material handling/back injury <br /> • Striking(slips/trips) <br /> • Struck-by injuries <br /> Qualified Exposure Risk: Moderate <br /> Primary"Control(s)": <br /> • Substitution (Use good lifting techniques. Use team lifting.) <br /> • Isolation (Establish Exclusion Zone around drilling equipment.) <br /> • Good housekeeping (Keep work area free of unnecessary obstructions and equipment.) <br /> • PPE (Fluorescent vests and hardhats.) <br /> 3.1.1 Material Handling/Back Injury <br /> Hazard: It is expected that field personnel will be required to lift heavy equipment and supplies and/or <br /> perform arduous tasks during this project. Accordingly, back injuries or physical strain may be caused <br /> by: routine lifting or one-time-only lifting; the weight of a lifted object; the frequency of lifting; <br /> bending, twisting, or rotating during lifting; prolonged sitting; exposure to vibrations; poor arch <br /> support in shoes; and, not stretching prior to physical activity. If the following "control' mechanisms <br /> are not exercised, debilitating back injury may occur. <br /> Project No.58475-06-70 -6- April 25,2003 <br />
