BACKGROUND
To prevent slip and fall events at the workplace, mechanical slip testing is conducted on shoes. Such experiments may involve redundant testing across floorings and contaminant conditions, causing wasted time and effort.
PURPOSE
Quantify the correlations between shoe traction across different contaminant-flooring conditions to reduce redundant slip testing efforts.
METHODS
The available coefficient-of-friction (ACOF) was quantified for 17 shoes across five floorings and three contaminant conditions. Redundant testing conditions were identified when the shoe ACOF values for one floor-contaminant condition were highly correlated with a second floor-contaminant condition.
RESULTS
High correlations were observed among quarry floorings across different contaminants and among vinyl (composite tile) floorings with the same contaminant. However, vinyl floorings exhibited low correlations with quarry floorings. Low correlations were also observed across contaminants within vinyl tiles.
CONCLUSIONS
This study was able to determine the generalizability of traction performance of shoes across vinyl and quarry floorings. This information is anticipated to reduce redundant traction testing of shoes across vinyl and quarry floorings.
背景
为预防工作场所的滑倒和跌倒事件，需对鞋子进行机械防滑测试。此类实验可能涉及在不同地板和污染物条件下的重复测试，导致时间和精力的浪费。
目的
量化不同污染物-地板条件下鞋子牵引力之间的相关性，以减少重复的防滑测试工作。
方法
对17双鞋子在五种地板和三种污染物条件下的有效摩擦系数（ACOF）进行量化。当一种地板-污染物条件下的鞋子ACOF值与另一种地板-污染物条件高度相关时，确定为重复测试条件。
结果
在不同污染物的采石场地板之间以及相同污染物的乙烯基地板（复合瓷砖）之间观察到高度相关性。然而，乙烯基地板与采石场地板的相关性较低。在乙烯基瓷砖内的不同污染物之间也观察到低相关性。
结论
本研究能够确定鞋子在乙烯基地板和采石场地板上牵引力性能的可推广性。预计该信息将减少鞋子在乙烯基地板和采石场地板上的重复牵引力测试。
