Postural stress and risk conditions in manual load handling of Chilean industrial workers

Introduction: Although, there is a current regulatory framework for optimal manual handling of loads to preserve health conditions in the industrial sector, technical assessment and use certain instruments are still required diagnosis occupational hazards. This study aimed identify hazards associated with load industry workers estimate those resulting from postural stress. Methods: Fifty-two (52) took part this cross-sectional study. All participants were evaluated using Manual Handling Guide Reba tool. Subjects characterized, risks different tasks detected. Results: 59.6% between 18 45 years old. Lifting, lowering, transporting activities had repetitive task risk 94%, exceeding weight limit 85.7% cases. Pushing pulling activities, mostly showed working 82% high perception initial effort (Borg> 8). score warned intervene immediately both types tasks. Conclusion: Risk found constitutes an alert that suggests reviewing compliance regulation, as well effective pauses improvement strategies minimize physical efforts used by workers.
