8、rbottom and the contaminant,and another interface between thecontaminant and the walkway surface.4.2 Aggressive contaminants create a gross separation be-tween the footwear bottom and the walkway surface,where theleast dimension of solid contaminants or the depth of highlyviscous liquid contaminants

9、 is greater than the height of thewalkway surface protrusions or asperities,and/or greater thanthe depth of texturing or tread of footwear.Aggressive con-taminants are exemplified by high viscosity liquids or semi-liquids such as juicy fruits and vegetables,rounded objects thatact as roller bearings

10、 such as rounded stones and gravel on hardsmooth surfaces,manufacturing scraps and byproducts on thewalkway surface,snow,ice,mud,and other similar contami-nants.4.3 Primary control of contaminants should be to eliminateor contain contaminants at the source to prevent contamination.Secondary control
