Abstract

The surface conditions of ground surface coatings, which are widely used in working environments exposed to various pollutants, were evaluated from a safety perspective. In this work, static and dynamic friction coefficients and safe angle of inclination between some floor coverings exposed to different pollutants for various reasons and some shoe sole materials that are widely used in working environments were determined. The interaction between soil, floor, and surface contaminations were evaluated statistically. In particular, the ground surface contaminated with contaminants such as water and surface cleaners, which significantly reduce the security of the floor is studied. ANOVA results showed that the floor covering, shoe sole samples, and floor contaminants were significant for each variable of the friction coefficient (μ) (p <0.05). It was determined that the correlation between two factors and three factors between a floor covering, shoe sole samples, and floor surface contaminant conditions significantly affects the friction coefficient (μ). Seven floor samples used in the study were evaluated in terms of safety classification and the results ranking from the highest to the lowest were "Granite ceramic with a glossy surface", "PVC linoleum coating", "Laminated wood parquet", "Matte surface ceramic", "Rough surfaced ceramic", "Matte, rough, non-slip, fireproof ceramic, "Natural granite stone (processed)". When the effect of floor samples on the static friction coefficient is examined, safe ones according to the DIN 51097 standards for all working areas; it has been determined that "PVC linoleum coating" (X̄ = 0.52), "Laminated wooden parquet" (X̄ = 0.48), "Granite ceramic with a glossy surface" (X̄ = 0.46).

Abstract

Çeşitli kirleticilere maruz kalan çalışma ortamlarında yaygın olarak kullanılan zemin yüzey kaplamalarının yüzey koşulları güvenlik açısından değerlendirilmiştir. Çeşitli sebepler ve çalışma ortamlarında yaygın olarak kullanılan bazı ayakkabı taban malzemeleri belirlenmiştir. Toprak-zemin etkileşimi , ve yüzey kontaminasyonları istatistiksel olarak değerlendirildi, zeminin güvenliği araştırıldı. ANOVA sonuçları, zemin kaplaması, ayakkabı tabanı numuneleri ve zemin kirleticilerinin sürtünme katsayısının (μ) her bir değişkeni için önemli olduğunu gösterdi (p <0.05). Zemin kaplaması, ayakkabı tabanı örnekleri ve zemin yüzeyi kirliliği arasında iki faktör ve üç faktör arasındaki korelasyonun olduğu belirlendi. Doğal koşullar sürtünme katsayısını (μ) önemli ölçüde etkiler. Çalışmada kullanılan yedi zemin numunesi güvenlik sınıflandırması açısından değerlendirilmiş ve en yüksekten en düşüğe doğru sıralanan sonuçlar "Parlak yüzeyli granit seramik", "PVC linolyum kaplama", "Lamine ahşap parke", "Mat yüzey seramik", "Pürüzlü yüzey seramik", "Mat, pürüzlü, kaymaz, yanmaz seramik, "Doğal granit taş (işlenmiş)" olmuştur. DIN'e göre güvenli olanlar tüm çalışma alanları için 51097 standartlarında; "PVC linolyum kaplama" (X̄ = 0.52), "Lamine ahşap parke" (X̄ = 0.48), "Parlak yüzeyli granit seramik" (X̄ = 0.46) olduğu belirlenmiştir.
