Posture Analysis and Design of Pyrite Disposal Work Tool CFSPP Unit 1 and 2 PT ABC

The working sheet is prepared as a tool for quantitative analysis of the physical workload and ergonomic suitability of the workplace design based on the physiological characteristics of workers using the approach of applied ergonomics. The first component is the Anthropometric calculations that aim to reflect and match the human body dimensions with the workstation parameters and dimensions of the tools and peculiarities of body positioning needed for the work performance. The measurements used for analysis, including sitting height, arm length, hand reach, and shoulder height, are processed through population percentiles (5th–95th percentile) to ensure that the proportionally designed office fits 95% percentage of workers with the concept of the universal design. The next component includes the postural risk assessments with the REBA and RULA methods. The REBA and RULA methods were used to analyze the calculated body dimensions that represent the workstation and tool design in terms of actual body part position. The neck, back, legs, and upper limbs positioning real measurements were then assessed according to the score table representing levels from low to very high hazard. It was the basis for recommendations on introducing the workplace engineer and the postural retraining measures. The final section of the working sheet calculates the Worker Productivity as the ration between the real output vs. SOP output. Considering cycle time, the number of units, work efficiency, and downtime due to fatigue and not ergonomic position, Worker Productivity could be highly associated with the RULA and REBA. It offers the insight of the impact of the intensive workload on the field results. The working sheet is created with an Excel application to provide dynamic calculations and facilitate its use in the different job settings like manufacturing, oil & gas, or processing. It also supports the evidence-based approach in workspaces enhancement and assessment of ergonomic protective action. Each of the methods includes information and estimate about the ergonomic risk that is aimed at the accumulation of the workplace efficiency overview.
