<![CDATA[Background. Cement production exposes employees to machinery, moving equipment, energy, and material-handling hazards. Routine safety briefings may not strengthen hazard recognition in realistic situations. Objective. To evaluate whether a four-week Structured Visual Safety Briefing Program improved hazard recognition, safe-work compliance, near-miss reporting readiness, and safety response confidence more than existing briefing practice. Methods. A non-equivalent control group pretest–posttest quasi-experiment was conducted among 120 production employees (60 per group; purposive sampling) at PT Semen Indonesia (Persero) Tbk, Tuban Plant, from March to July 2026. The intervention comprised 12 sessions over four weeks using hazard images, colour-coded cues, and scenario questions. Outcomes, collected through Google Forms, were self-reported hazard recognition (HR), a 10-item objective visual hazard recognition test (HRT), safe-work compliance (SWC), near-miss reporting readiness (NMR), and safety response confidence (SRC). Difference-in-differences (DiD) with participant-clustered standard errors was the primary analysis, supplemented by ANCOVA. Results. All 120 participants provided matched data. The intervention group improved more than the comparison group on every outcome (DiD: HR = 1.01, 95% CI [0.79, 1.23]; HRT = 2.20 points, [1.45, 2.95]; SWC = 0.88; NMR = 0.92; SRC = 0.78; all p < .001; Hedges’ g = 1.04–1.64). Results were robust to adjustment for baseline scores, tenure, prior training, and shift status. Conclusion. Adding structured visual content to routine safety briefings was associated with larger short-term gains in hazard recognition and related readiness outcomes than existing practice. Non-random allocation, self-reported outcomes, and immediate posttesting limit causal inference; the program should supplement, not replace, formal training and engineering controls.]]>
