4. Purge and sample well 4a. EXPOSURE/CONTACT: To 4a. Open and fill sample jars slowly to avoid splashing and contact with contamination(e.g.,SPH, preservatives. contaminated groundwater,vapors) 4a. Wear cut-resistant gloves and chemical-resistant disposable gloves and/or sample preservatives. when sampling. 4a. Fill sample containers over purge container to avoid spilling water onto the ground. 4a. Use an absorbent pad to clean spills. 4a. When using a bailer to purge a well, pull the bailer slowly from the well to avoid splash hazards. 4a. When sampling or purging the water using a bailer,pour out water slowly to reduce the potential for splash hazards with groundwater. 4a. When using a tubing valve always remove the valve slowly after sample-collection to release any pressure and avoid pressurized splash hazards. 4a. When collecting a groundwater sample always point sampling 4b. CONTACT: Personal injury from apparatus(tubing, bailer,etc.)away from face and body. cuts,abrasions,or punctures by 4b. To avoid spills or breakage, place sample ware on even surface. glassware or sharp objects. 4b. Do not over tighten caps on glass sample ware. 4b. Wear chemical-resistant nitrile disposable gloves over cut-resistant (i.e., Kevlar)gloves when sampling and handling glassware(i.e., VOA vials)or when using cutting tools. 4c. EXERTION: Muscle strain while carrying equipment. 4c. Use proper lifting techniques when handling/moving equipment, bend knees and keep back straight. 4c. Use mechanical assistance or team lifting techniques when equipment is 50 lbs.or heavier. 4d. CONTACT: 4c. Make multiple trips to carry equipment. With traffic. 4d. See 1b. 4e. CONTACT: Pinch points with groundwater 4e. Wear leather gloves when working with groundwater pumps. pump components(i.e.,wheel,line, 4e. Never place hands on or near pinch points such as the wheel, clamps). clamps or other moving parts during pump operations. 4e. Use the correct mechanisms,such as a pump reel,to lower pump into well. 4e. Never attempt to manually stop any moving part of equipment including hose reels and/or tubing. 4f. EXERTION:Muscle strain from repetitive motion of bailing and 4f. See 4c. sampling a well. 4f. Include a stretch break when repetitive motions are part of the task. 5. Management of purge 5a. EXPOSURE/CONTACT: To 5a. Do not overfill container and pour liquids slowly so that they do not water. contamination(e.g.,SPH, splash. contaminated groundwater, 5a. Properly dispose of used materials/PPE in appropriate container in vapors). designated storage area. 5b. EXERTION: 5b. Use proper lifting techniques when lifting/carrying or moving Muscle strain from lifting/carrying container(s)(see 4c.). and moving containers. 5b. Do not overfill container(s). 6. Decontaminate equipment. 6a. EXPOSURE/CONTACT: To 6a. Work on the upwind side,where possible,of decon area. contamination(e.g.,SPH, 6a. Wear chemical-resistant disposable gloves and safety glasses. contaminated groundwater, 6a. Use an absorbent pad to clean spills. vapors). 6b. CAUGHT: Pinch points associated 6b. See 2b. with handling hand tools 6b. Inspect hand tools for sharp edges before decontaminating. ' Each Job or Operation consists of a set of tasks/steps. Be sure to list all the steps needed to perform job. z A hazard is a potential danger. Break hazards into six types: Contact-victim is struck by or strikes an object; Caught-victim is caught on,caught in or caught between objects;Fall-victim falls to ground or lower level(includes slips and trips);Exertion-excessive strain or stress/ergonomics/lifting techniques;Exposure-inhalation/skin hazards;Energy Source-electricity,pressure,compression/tension. Using the first two columns as a guide,decide what actions or procedures are necessary to eliminate or minimize the risk. List the recommended safe operating procedures. Say exactly what needs to be done-such as"use two persons to lift". Avoid general statements such as,"be careful'. ROUX ASSOCIATES, INC.
