Abstract
Slips and falls across the workplaces account for several fatal and non-fatal traumatic injuries worldwide. Consequences of these accidents include deterioration of the overall quality of living and increased economical strains through hospitalization and compensation costs. Unintentional slips usually occur due to a sudden decrease in the friction of shoes and the floorings. Due to low purchasing parity in the low- or middle-income countries (such as India), awareness related to the footwear’s slip resistance performance often goes neglected. Due to this, the public commonly choose to buy low-cost footwear. Also, footwear traction performance deteriorates with progressive wearing. Therefore, assessing the performance of footwear in new and worn-out conditions across common slippery situations is essential. In this work, ten Indian-manufactured formal shoes were assessed for its slip-resistant performance across three common floorings in dry- and water-contaminated conditions using a novel slip testing device. The results indicated that most of the selected low-cost footwear showed high slip risks across wet flooring conditions. Shoes with absence or worn-out treads at the heel region led to the availability of much lower friction at the shoe–floor interface. Shoes with soft outsoles, when worn, exhibited large worn areas and high slipping risks as compared to the ones with hard outsoles (R2 = 0.92). The findings from this study are anticipated to lead to better understanding of the slip risks associated with low-cost formal footwear in India, as well as provide guidelines for their selection and timely replacement.
