Abstract


This is cross-sectional descriptive research collected data were collected by structured interview and observation of work posture ergonomics risk assessment using REBA (Rapid Entire Body Assessment) and NIOSH Lifting Equation and prevalence of musculoskeletal disorders in workers organic fertilizer factory, Khok kruad subdistrict Mueang district Nakhon Ratchasima province. The study sample were 132 workers.

The result found that prevalence of musculoskeletal disorders system with employees for 7 days is the workers in the production department had the highest pain in the lower back area, 36.21%, followed by 32.76% pain in the shoulder area, and 29.31% pain knee and the staff of the packing department had the highest pain in the lower back 51.35% followed by pain in the foot area 29.73% and pain shoulder 27.03%, respectively. The NIOSH Lifting Equation found the Lifting Index>1 at 72.97%, REBA at level 3 at 50%, Level 4 at 36.21%, and Level 5 at 6.90. coffee was a factor associated with ergonomic risks.
