4、mitations prior to use.2.Summary of Guide2.1 Foreign material on a walkway surface often causes slipand fall accidents.A slip can occur because foreign materialpresents an additional interface between the shoe bottom and awalkway surface.The interface between the shoe bottom andthe walkway is replac
5、ed by an interface between the shoebottom and the foreign material,and another between theforeign material and the walkway.Although the foreign mate-rial should be removed,it is not always easy to remove prior touse of the walkway or as the foreign material is spilled.In veryfew cases can shoe botto
6、ms be designed to provide adequateslip resistance to foreign materials.Instead,walkway surfacesshould be self-cleaning as they are used by pedestrians.2.2 This guide sets forth factors to consider in the design ofwalkway surfaces likely to be affected by foreign materials thatmay result in slips.The
7、se considerations concern metal walk-way materials,abrasive materials used on walkways,andclimbing systems.3.Significance and Use3.1 When the conditions are such that foreign materials cancome between shoe bottoms and a walkway surface,effortsshould be made to design the walkway surface to remove th
8、eforeign material from between shoe bottoms and the walkwaysurface.3.2 This type of slip hazard is often found in manufacturingand maintenance processes where foreign materials are fre-quently present on walkway surfaces.Examples are:foodpreparation and processing areas,rendering operations,trans-po
9、rtation and cargo handling activities.4.Procedure4.1 The presence of foreign materials on walkway surfacesoften causes people to slip.Most foreign materials,if presenton a walkway,will lower slip resistance.A foreign material incontact with a shoe and a walkway presents two additionalsurfaces:the to
10、p of the foreign material mating with the bottomof the shoe sole,and the bottom of the foreign material matingwith the walkway surface.Obviously,keeping the walkwaysurface clean of foreign materials is the best method toeliminate this potential hazard.This is not always possible,however,while routin
11、e operations are being performed.4.2 Treatment of the walkway surface with an abrasivematerial is a frequently used remedy when the foreign sub-stance is soft or of low viscosity.The function of an abrasivewalkway surface is often misunderstood.The ideal approach toreduce slipping on walkways is to
12、eliminate the two additionalsurfaces caused by the presence of the foreign material.Asharpabrasive incorporation into the walkway surface will allow footpressure to break up the foreign material and force it into voidsbetween peaks of the abrasive.This process retains twosurfaces:the walkway and the
13、 shoe bottom.Important consid-erations in the selection of an abrasive treatment are:wearresistance,resilience of abrasive material,density of abrasivetreatment,means of attachment of treatment to the walkwaysurface,sanitary conditions,and appropriate abrasive size.4.2.1 The type of abrasive used is
14、 also an important factor toconsider.For instance,sand,bonded to a floor surface,workswell when first applied because sand is a relatively softmaterial.However,the sharp edges of the sand particles areeasily rounded by wear,and foreign material tends to remainon top of the abrasive particles.Proper
15、selection of abrasivematerial depends upon the particular circumstances of theproblem area.4.2.2 Because some abrasive particles are brittle,they breakoff during use and become ineffective.1This guide is under the jurisdiction of ASTM Committee F13 on Safety andTraction for Footwear and is the direc
