Safe lifting and material handling techniques, computer ergonomics, and stretching are some of the topics covered. ARMS Software This program can be loaded onto individual PCs and laptops to periodically remind users to take a mini-break and perform stretching exercises. The program keeps track of keystrokes and mouse movements and pops up a stretching video once a pre-set threshold is exceeded. The threshold can be adjusted and the user can disable the program, if desired. The master copy of this program is kept in the Safety, Health, and Environmental Services Department in Butte.

3 computer Safety Slide Rule This is a quick workstation setup and stretching reference that can be handed out during Ergonomic evaluations, training sessions, etc. A supply of this item is maintained in the Safety, Health, and Environmental Services Resource Library. Pamphlets A fifteen page fully illustrated color pamphlet titled The Fit Back Workout is stocked in the Resource Library. training CDs Two Ergonomic programs have been loaded onto designated PCs at major operating locations, primarily the division operating centers. One covers back safety and the other covers computer / workstation ergonomics. These are interactive programs, which include knowledge tests. Safety and Health Handbooks Both of the handbooks contain fairly extensive sections on ergonomics. Team members should be reminded that these should be reviewed periodically. Job Safety Analysis Many of the JSAs for field tasks identify potential Ergonomic hazards and should be reviewed before doing an in-depth Ergonomic Analysis .

4 JSAs are kept on the intranet at the Safety, Health, and Environmental Services site. Instructions for Conducting Office Ergonomic Evaluations Purpose Reduce or Eliminate Ergonomic Hazards and Injuries Continuous Improvement Follow Good Business Practice Method Compare existing work surface heights, viewing distances, reach distances, and chair design to current recommended design criteria. Augment work areas with accessories, such as wrist rests, foot rests, etc., where beneficial. In some cases, observe task performance to identify and reduce risk factors associated with musculoskeletal disorders such as awkward postures, excessive repetition or strenuous lifting. Solicit improvement ideas from employees directly involved in task performance. Provide one-on-one training to individuals on reducing risk factors directly under their control. Tools Job-Site Questionnaire and workstation Checklist if possible, provide the questionnaire to employee(s) before the evaluation is performed, to determine what parts of the body are being affected.

5 Complete the checklist during the on-site workstation evaluation. (See Office Evaluation Forms Section.) Ergo Slide rule hand out one to each employee being evaluated and demonstrate its use as a reference. (See Office Handouts Section.) ARMS Software offer to each employee to promote rest breaks and stretching. Final Report Issue a report of the findings and recommended corrective actions to management for appropriate action. Use the standard format shown in the Office Evaluation Report Section. Update the corrective action table in the report as corrections are completed. Furniture and Equipment Purchases Involve the appropriate facilities personnel in any furniture purchase decisions. Examples of furniture and accessories to improve workstation ergonomics are shown in the Office Equipment Section.

Your arms will then hang comfortably at your side, or resting comfortably on the arm rest, this will take the strain off your upper back and shoulders. 5. Is the top of your screen higher, lower or even with your eyebrows? Higher Lower Even The screen should be no higher than eye level to minimize eye movement. You should also tilt back to the screen about 10-20 degrees for easier viewing (providing it doesn t increase glare). sehcni ?neercs gniweiv lanimret eht si seye ruoy morf raf woH .6 The viewing distance should range from 18-26 inches.

The purpose of the evaluation is to provide guidance in workstation use to the employees and to enhance user comfort by correcting any workstation design defects identified. Ultimately, this is intended to reduce the incidence of musculoskeletal disorders among computer users and the attendant costs.

10 workstation Evaluations The evaluations were based on currently recommended criteria for proper workstation design and input from each employee. The immediate needs at each workstation are summarized in the attached table. In the longer term, fully adjustable chairs should be budgeted to replace existing non-adjustable chairs in the dispatch and clerical work Comments During the evaluation it was noted that employees who had previously worked in the dispatch jobs had experienced musculoskeletal pain during that time. Upon leaving those jobs, the symptoms were said to have subsided. Work pace in the dispatch area may be a contributing factor to the development of symptoms in addition to workstation design. This suggests that a job rotation program could be beneficial once the dispatch workstations have been modified with adjustable keyboard and mouse REPORT EXAMPLE Ergonomic Evaluation (Location Name) Office computer Workstations Evaluation Date: Evaluation Performed By: EMPLOYEE DEFICIENCIES EQUIPMENT NEEDED COMMENTS EST.
