Abstract
This study examined how Chile’s Manual Material Handling guide is utilized by professionals with varying levels of training and expertise. A nationwide survey of 203 participants who applied the guide across 5900+ job positions revealed that while trained users reported better understanding, significant barriers persist—particularly confusing language, unclear flowcharts, and inconsistent regulatory implementation. Interestingly, the most experienced users were also the most critical. Findings indicate that improving the guide’s clarity, structure, and accessibility would enhance adoption. Recommendations include simplifying language, clarifying processes, standardizing reporting formats, and expanding training access to improve workplace risk assessments and occupational safety nationwide.
