Abstract:

<p style="text-align:justify">Ergonomics is the manipulation of a person's job about the environment, the tools and equipments, and the person in order to promote easier and safer job as well as productivity. This study specifically aimed to (1) assess the posture of pot makers while at work; (2) make a task analysis of pot making; (3) analyze their workstation; (4) determine possible existence of hazards in the workplace; (5) identify common work-related musculoskeletal disorders (WMSDs); and (6) determine if certain demographic factors are related to WMSDs. Descriptive-correlation design was utilized with regards the value of ergonomics among pot makers, particularly in Barangay Nagrebcan, San Nicolas, Ilocos Norte. Task analysis was divided into three phases: mixing, kneading, and molding. The study employed the Rapid Entire Body Assessment (REBA), Ovako Working Posture Analysis System (OWAS), Workplace Hazard Assessment, and the Discomfort Survey questionnaires. One representative sample of pottery maker was used in each phase to analyze the task, to assess the workstation, postures and the workplace. However, all the members were utilized for the discomfort survey. Task analysis showed that there were some constant awkward positions exhibited by the pot makers in doing their respective tasks: deep squatting and trunk bending. REBA showed that there were high risks of suffering of injuries while OWAS showed that several positions need corrective measures in the near future. Pot makers were accountable to some of the equipments used in the workstation that they do not exhibit correct postures and body mechanics. Presence of hazards was found: impact, dust, penetration, thermal, and rain. Low back and wrist/hands were the areas of the body where discomfort commonly occurred. This research is pertinent in providing awareness and this may serve as a basis for recommendation to improve productivity and welfare of employees among pottery industries in the Ilocos Region.</p>
