Name one way you can reduce the effects of repetitive motion stress on your body while at work
What is -Let the tool do the work -Stretch -Rotate away to other tasks regularly -Alternate hands -Vary your technique

Name two ergonomic recommendations for proper chair set-up.
What is -Choose a chair with good adjustability. -Choose a chair that is a proper fit for the worker. -Sit with hips all the way back in chair. -Adjust seat height so your feet are resting flat on the floor and thighs are parallel to the floor. -Use a footrest if your feet are not comfortably resting on the floor or if your legs are not straight and pressure is felt on thighs. -Shoulders should be down and relaxed resting back into chair, with elbows at a comfortable bend at sides. -Adjust seat back height (lumbar support) so the inward curve of your lower back is supported. -Adjust seat back tilt angle so that your upper and lower back is comfortably supported in a relaxed working posture. -If able, adjust the depth of your chair to allow 1-3 inches between the edge of the seat and the back of your leg.
200
What is the most important principle of ergonomics?
What is Let the tool/equipment do the work! "It's all about having the right tools for the job."

Name three safe lifting techniques
What is -Use a cart/equipment whenever possible -Check weight content before lifting -Bend at knees-power squat -Keep back straight -Build a bridge -Wide base of support -Hold the load close
200
Two part question: 1. True or False, the angle of the wrist affects the amount of hand strength an individual has? 2. What percentage of loss of strength can there be when working with a bent wrist posture?
What is 1. true 2. up to a 55% loss of strength
200
These were the body parts with the highest severity (cost) of injury for Prairie Electric.
What is back and shoulders.
300
In effort to reduce reaching across body and twisting when typing on the keyboard, where should the keyboard be positioned (which two letters on the keyboard should the worker's nose be positioned between)?
What is letters "G" and "H" -If needed, try using the mouse on the left side
300
Name two examples of ergonomic solutions that have already been implemented at Prairie Electric
-Purchased new benders with longer handles to help reduce bending. -Reduction in weight/size with the new LED lights purchased to help reduce strain/sprain type injuries to worker’s shoulders, elbows and backs (Pete). -Porta-band for cutting metal conduit or plastic pipe. -Electric screwdriver with adjustable grip positions. -Mechanical ladder hoist/rack for vehicle.

Name two ergonomic/strain injury reduction strategies for lifting spool wire
What is -Store smaller spools of wire on a work surface of appropriate height (power zone)to minimize bending when lifting. -Use mechanical means such as forklifts, hoists or overhead cranes to move and lift large spools. -Ensure there is adequate access to spool racks. Spools that are used most frequently should be conveniently stored between waist and shoulder height (power zone). -Use spool rollers instead of elevated racks when removing wire from the spools. -Use two or more workers to lift spools when mechanical means are not available.
300
This is the type of tool that should be used when the force is applied horizontally (in the same direction as your straight forearm and wrist).
What is A tool with a bent handle
300
This was the #1 type (nature) of injury for Prairie Electric
What is strains
400
Name two common stressors of the shoulders, arms, wrists, and hands when working on a computer
What is -Extended wrist posture -Forward reaching/forward rounded shoulder posture -Contact stress on workstation -Mouse not on same level as keyboard -Hands/fingers drifting inward or outward
400
This is something you can do before, during, and after work to help reduce the risk of strains and sprains, improve flexibility, and reverse the stress placed on your muscles and joints during work activity
What is stretching
400
Name two strain injury prevention strategies for proper storage, organization, and staging of materials and tools.
What is -Store/organize storage areas so that the heavy and most frequently used items are in the power zone. -Avoid storing heavy items at high or low levels, or at a far reaching distance. -Store light weight, less frequently used items on top and bottom shelves. -Do not stack materials on a cart higher than eye level to avoid having to bend to the side to see around the load. -Roll-out truck bed decks for storage/organization of tools in truck bed -Truck ramps

Name two of the four ergonomic/strain reduction strategies that were discussed for installing control wiring
What is -Use stab-in switches and outlets. For residential work, use self-locking stab-ins. For larger jobs, use stab-ins with a side-screw fastener. -Use tool-less connectors, such as low-voltage spring action screw-less terminals where only a small amount of force is needed to insert wire, and no twisting is required. -These connectors are easier and faster to use, thereby increasing productivity and reducing ergonomic risks. -When stripping wires use proper size or spring-loaded strippers that are in good condition (sharp teeth). This reduces the amount of pulling force required. -Limit the time workers perform similar, repetitive tasks that affect the same muscle groups. For example, rotate hand-intensive tasks with lifting tasks.
400
This is the average cost of a back injury in America.
What is $25,000 up to $85,000 for a back injury requiring surgery
500
Name two other important considerations for helping reduce cumulative fatigue at your workstation.
What is -Position frequently used items within easy reach in front of you. -Change positions twice an hour (every 30 minutes) -Consider using a different ergonomic device if uncomfortable (i.e. Ergonomic natural keyboard, vertical “handshake” mouse, etc.) -Stretch -Eye break (The 20-20-20 rule) -Do a different task (i.e. filing, copying, retrieving items from the printer, paper work, etc.)
500
Name three common causes of musculoskeletal disorders
What is -Forceful exertions -Repetition -Awkward posture -Contact stress -Prolonged exposure to vibration -Inadequate muscle recovery time
500
Name two ergonomic/strain injury reduction strategies that can be used to reduce the force required when pulling wire.
What is -Use a tugger or mechanical wire puller when pulling larger gauge wire -Use an appropriately positioned portable pulleys -Use a spool roller -Pull in the power zone -Install inspection boxes at appropriate intervals -Use platforms, scaffolds, or lifts so workers can raise themselves and turn to face the direction of work when pulling.
500
Name three ergonomic/work simplification strategies for transporting tools.
What is -Plan ahead, make sure you have the right tools and equipment to do your job. -Transport tools and supplies (tool box) on a cart vs. carrying them. -When possible (with reoccurring, long-standing accounts), leave cart with all tools and supplies at client’s location -Use padded belts and suspenders to evenly distribute the weight between the shoulders and the waist- -Arrange tools in bags so that their weight is distributed evenly. -When possible, reduce the weight of the tool belt by reducing the number of tools carried to those necessary for the task or transport tools on a cart. -Use a backpack-style tool bag to distribute the weight of tools over the body and improve posture if tools must be carried for extended distances.
