Analyze 2POTENTIAL HAZARDS 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 the 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 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 the sampling apparatus(tubing,bailer,etc.)away from the face and body. 4b. CONTACT: Personal injury from 4b. To avoid spills or breakage,place sampleware on an even surface. cuts,abrasions,or punctures by 4b. Do not over-tighten caps on glass sampleware. glassware or sharp objects. 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 approved cutting tools. 4c. EXERTION: Muscle strain while 4c. Use proper lifting techniques when handling/moving equipment, carrying equipment. bend knees,and keep back straight. 4c. Use mechanical assistance or team lifting techniques when equipment is 40 lbs.or heavier. 4c. Make multiple trips to carry equipment. 4d. CONTACT: 4d. See 1 b. With traffic. 4e. CONTACT: 4e. Wear cut-resistant gloves when working with groundwater pumps. Pinch points with groundwater 4e. Never place hands on or near pinch points such as the wheel, pump components(i.e.,wheel,line, clamps,or other moving parts during pump operations. clamps). 4e. Use the correct mechanisms,such as a pump reel,to lower the pump into the well. 4e. Never attempt to manually stop any moving part of equipment, including hose reels and/or tubing. 0. EXERTION: Muscle strain from 4f. See 4c. repetitive motion of bailing and 4f. Include a stretch break when repetitive motions are part of the task. sampling a well. 5. Management of purge 5a. EXPOSURE/CONTACT: To 5a. Do not overfill the container,and pour liquids slowly so that they do water. contamination(e.g.,SPH, not splash. contaminated groundwater, 5a. Properly dispose of used materials/PPE in an appropriate container vapors). in the 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 the 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. ' 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.
