Ergonomic Risks for Ice Production Employees and Assessment of Their Occupational Health and Safety: A Case Study in Surat Thani, Thailand

Information from the abstract

Musculoskeletal disorders (MSDs) represent a critical global challenge to workforce productivity. In Thailand, these disorders are particularly prevalent in labor-intensive industries such as ice manufacturing, where workers face significant ergonomic hazards. Addressing this gap, the present study aimed to assess the occupational health, safety, and ergonomic risks facing workers in ice production facilities. This cross-sectional descriptive study investigated production workers who were employees in two of eight ice manufacturing plants in Surat Thani, Thailand, using the Rapid Entire Body Assessment (REBA) method. A structured occupational health and safety risk assessment questionnaire and the REBA evaluation form were used to collect data. All participants were male, averaging 30.4 (±8.5) years old. Regular pain areas included the upper/lower back, hips/thighs, shoulders, wrists, and ankles. Ergonomic assessments showed high overall risk due to heavy lifting, repetitive tasks, and cold environments. Based on REBA scores, 13.04% were in the very-high-risk group (score ≥ 11) and 65.22% in the high-risk group (score 8–10). Most production workers in ice plants faced high ergonomic risks, especially from postures affecting the upper and lower back. Training should be provided to promote awareness of risky postures and proper lifting techniques. Mechanical aids and back-support equipment are also recommended to help prevent musculoskeletal injuries.
