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