The 3E Process 3
The 3E Process 1. Engineering Optimal intervention to eliminate all risks of injuries Create, improve, or redesign a tool or piece of equipment Adapt a job description or develop a safety policy based on physical demands If engineering is cost-prohibitive or impractical, we shift to Ergonomics. 4
The 3E Process 2. Ergonomics A medical ergonomics approach that uses anatomy, physiology, and body mechanics to train workers to complete job tasks safely Evaluate all job functions and job tasks for at-risk behaviors Develop best-practice ergonomic methods to mitigate risk at each level Instruct employees in avoiding at-risk movements and enhancing fluid body mechanics If ergonomics cannot fully mitigate risks of injury, we shift to Exercise. 5
The 3E Process 3. Exercise Time-efficient interventions designed to prepare the body for the physical demands of job tasks Properly warm up the body before beginning job tasks Reset the body after repetitive movements Develop personalized strength & conditioning programs 6
Engineering Interventions Pushing/Pulling Quick Restorer Cart Due to the weight of the original model (140-160 pounds), employees were often forced into various degrees of lateral trunk flexion and rotation in order to control the transformer Switching to the new, lighter model (60-80 pounds) reduces the risk of overloading the shoulder/elbow muscles Facilitates proper posture when lifting or pulling transformer Original Model New Model 7
Engineering Interventions Retrieving Grounding Line Old method: Using mobile equipment and vehicle Manually pulling ground cable from cement requires OE to exert 39 pounds of force Using Grip-All to ground cable to rear of truck pinches shoulder structures and increases risk of forearm, wrist, & hand trauma 8
Engineering Interventions Retrieving Grounding Line, cont d New method: Using a retractable ground reel and cable Reduces overall stress on body by automatically rewinding ground cable; the OE only has to exert 7 pounds of force to pull cable from reel Install attachment point at rear of passenger side box so that clamp end of ground cable is easy to access Eliminates need for Grip-All and allows for proper stabilization of right hand & wrist 9
Ergonomic Interventions Avoiding the Impingement Zone While Creating a Line Secondary Main Repeated movement of the arms into the Impingement Zone (at or above shoulder height) compresses the shoulder tendons, nerves, and ligaments. Instead, a slightly lowered arm position prevents overload of the shoulder structures during manipulation of heavy cable. Use the elbow as a marker for proper arm position. For example: while bending the line secondary main and attaching it to the bus, the elbows should be lowered about 6 below the shoulder. Safer 10
Ergonomic Interventions Maintaining Back Function While Lifting Fault Wizard Unintentional back hyperextension may occur as a physical compensatory reaction to the weight (60 lbs.) and length (17 in.) of this equipment. Whenever possible, two employees should lift and carry the equipment to lessen the overall load. Grasp the Fault Wizard with 4 fingers while pressing thumb against side Independently, maintaining proper posture can improve back function. At-Risk Safer 11
Ergonomic Interventions Utilizing Jack Strap Pivot Point to Engage Arms Equally Efficiently utilize the jack strap pivot point by grasping and pushing with the superior hand and pulling equally with the lower hand: this distributes the force needed for cable tension equally to both arms in order to prevent muscle fatigue. Engage all fingers and thumbs on the strap to improve hand & wrist stability At-Risk Safer 12
Ergonomic Interventions Safer Positioning While Using the Grip-All Maintain All-In form: keep shoulders in line with the hips, elbows in line with the navel, and wrists in line with the forearm Increase available strength of shoulders, elbows, and wrists Prevent fatigue of rotator cuff, wrist tendons, and forearm flexors 13
Exercise Interventions Pulling/Pushing PhazeSaver Pulling or pushing the PhazeSaver with one hand places stress on the pulling shoulder Dynamic warm-up with emphasis on neutral spine position to distribute vertical force throughout the core to counteract the force used to push/pull the PhazeSaver Exercise with the WOW (short-range speeds flexion and internal/external rotation) to improve shoulder stability & control At-Risk Post-Task Exercises 14
Exercise Interventions Engaging the Abdominals During & After Splice Pit Tasks Squatting & leaning forward while repairing the primary causes employees back muscles to contract vigorously to maintain proper posture Post-task abdominal muscle exercises counteract continual paraspinal muscle contraction and create neutral spine position Can be performed using the bucket truck At-Risk Post-Task Exercises 15
Exercise Interventions Improved Activation of the Quadratus Lumborum While Removing Cable The side plank can be used to activate the quadratus lumborum & obtain low-back/pelvic stability. The objective is to improve awareness of muscle activation and contract this muscle while removing cable. Muscle Recognition At-Risk Best Practice 16
