  1. An Analysis of Work-Related Musculoskeletal Disorders for 19-Liter Drinking Water Distribution Personnel M.EMIR MEMIK MELIH DIKER

  2. Introduction • In this study a questionnaire is designed and applied to 100 randomly selected 19-liter water container personnel, in the five main cities of TRNC . • Using the results of the analysis of the questionniare, anthropometric principles, and lifting standards, arrangement for better conditions and work guidelines are suggested to minimize the risk of injury and musculoskeletal disorders of workers.

  3. Design Analysis • The containers are made of polycarbonate, which is a tough, heat-resistant material. When filled with water, it has a weight of about 19.750kg. • The absence of a handle in the first one shown above makes lifting even more difficult. The top of the container becomes the only possible option for lifting this container. • The grip circumference for this design type is not convenient as it forces pronationofthe arm and also exerts pressureon the wrist joint.

  4. Lifting Handle Design • This bottle has the same main features as the handle-less design, but with one big difference - the handle makes it easier to carry from stock to the customers, and a lot easier to install on a dispenser. The handle design also allows free flow of water through the container. • The major problem with the handle is that when the container is being cleaned, the handle part isn’t completely cleaned and this poses a health risk.

  5. The Lifting Standards • Standing symmetrically, unrestricted and upright. • Trunk should be upright and not rotated. • Horizontal distance to object should be less than 25 cm. • Height of grip should be less than 25 cm above knuckleheight. • Firm grip on the object (neutral wrist posture). • Lifting duration should be less than one hour per day. • Frequency of lifting should be less than or equal to 0.2 lifts per minute.  • Favorable environmental conditions.

  6. Work Musculosceletal Disorders for the Distributors 15% of Shoulder WMSDs 25% of Back WMSDs 10% of Hand/Wrist WMSDs 6% of Neck WMSDs 9% Leg of WMSDs 35% of No WMSDs

  7. The 19 Liter Water Container Usage • In the TRNC as well as in Turkey and many other parts of the world, it is evident that the usage of the water container as the medium for water delivery and usage has come to stay. • It has a couple of strong points. It does not pose any disposal or pollution threats, as it maintains a refilling usage method and the container is used for the sole purpose of drinking water, therefore no other liquids are ever put in it.

  8. Cont’d • It is used by nearly all members of the population as reflected in the survey analysis, save the extremely old and young, who are in the age limits where they cannot tolerate the weight of the container. • The distribution workforce is strictly a male workforce because strength is the obvious job requirement. The usage however, cuts across both genders.

  12. Conclusion • Employees are usually working between 10-12 hours. • Staffs are generally between of 37-47 ages, 61% of the employees are exposed to work related injuries. • These injuries consists of mainly in the waist and shoulders. • Majority of employees do not use carrier apparatus. This also leads to injuries, for the prevent injuries, stafs should be used carrier assist or tool carrier apparatus. • Container design must be improved.
