Job Safety Analysis <br /> <br /> <br />¹ JOB STEPS ² POTENTIAL HAZARDS ³ CRITICAL ACTIONS TO MITIGATE HAZARDS 4 RESPONSIBLE <br />PERSON(S) <br />Biological - Insect bites, <br />skin irritation, or allergic <br />reaction from <br />bites/stings from insects <br />inside well housing. <br />• Visually check for insects prior to opening the well. <br /> <br />• Have insect spray available to kill wasps/bees. <br /> <br />• Wear gloves, long sleeves, and pants to prevent insect bites. <br /> <br />Motion - Knee scraping <br />during sampling. • If kneeling, wear knee pads or place pad on ground to prevent <br />injury to knee. <br /> <br />Pressure - Concussion or <br />bodily injury from well cap <br />or plug under potential <br />pressure. <br />• If pressure relief valves are on well, release pressure prior to <br />opening well. Open well cap or plug at an angle away from <br />body. Keep face 2 feet clear of wellhead while opening. <br /> <br />• Wear safety glasses to protect eyes and a hard hat to protect <br />head. <br /> <br /> Chemical - Respiratory <br />irritation from vapor/gas <br />inhalation. <br />• Keep face clear of wellhead and work upwind of wellhead, if <br />feasible. <br /> <br />• Conduct air monitoring per HASP, stop work if readings are <br />above action levels. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />3. Begin purging <br />well and <br />collecting <br />parameter <br />measurements <br />Chemical - Skin irritation <br />from contact with <br />groundwater <br />• Lower and retract depth-to-water meter slowly to reduce the <br />potential for splashing. <br /> <br />• Wear Nitrile gloves over cut-resistant gloves to prevent hand <br />injury and skin irritation. <br /> <br />Chemical - Environmental <br />releases of well fluid. • Make sure tubing is secure in buckets, do not overfill <br />containers; pour water slowly into buckets/drums to minimize <br />splashing. <br /> <br />• If leakage is observed, stop purging activities immediately, stop <br />leakage. Block any drainage grate with sorbent pads. Call PM <br />to notify of any reportable spill. <br /> <br />Mechanical - Lacerations <br />from cutting materials, such <br />as plastic tubing. <br />• When cutting tubing, use tubing safety cutter tool. No open <br />fixed blades permitted. <br /> <br />• Keep hands 6 inches away from cutting edge of tools. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />4. Collect <br />groundwater <br />or free product <br />sample. <br /> <br />Motion - Back strain <br />from collecting samples. <br />• Submersible pump should be used in lieu of a bailer whenever <br />it inherently creates uncomfortable positioning and additional <br />strain. <br /> <br />• If using bailer, lift with legs keeping back straight. <br /> <br /> <br />Seed JSA - Well Gauging and Sampling_020714.docx - 2 -
