Replicating cheese maturing warehouse conditions in laboratory slip resistance testing: Identifying safety footwear for a specific working environment
本研究在模拟奶酪成熟仓库的污染地面条件下，测试了七种安全鞋的防滑性能，发现鞋跟更宽、接触面积更大的鞋子防滑性更好，且价格较高的鞋子防滑性更优。
This laboratory study assessed the slip resistance of seven safety shoes certified under ISO 20345:2021 in conditions mimicking a cheese maturing warehouse with floors contaminated by smear brine. Measurements of dynamic coefficient of friction (DCOF) were performed on polyurethane and tile surfaces, demonstrating that footwear with wider heels, larger contact areas, and lower local pressure exhibited higher slip resistance. Regression analyses indicated significant predictive relationships between heel width and contact area on slip resistance on the polyurethane surface, with notable differences in performance across shoe models. As practical guidance, this study found that the shoe with the widest heel (98 mm) and largest contact area (3716 mm 2 ) exhibited the highest slip resistance among the tested shoes. Additionally, a positive association between shoe price and slip resistance was observed, suggesting that the tested higher-priced shoes had better slip resistance characteristics.
