7、injury events are often caused by contami-nants on a walkway surface. Slips that occur because of thepresence of contaminants result from the additional interfacebetween the footwear bottom and the walkway surface. Theinterface between the footwear bottom and the walkwaysurface is replaced by an int

The intent of theself-cleaning process is to restore direct contact between thewalkway surface and the footwear bottom. Examples ofself-cleaning treatments include grates and spike-like asperi-ties.

20、ent of the walkway surface with abrasive mate-rials is a recommended slip-resistance enhancement when thecontaminants are soft or viscous. To be effective, the abrasivematerial must have prominent projections of sufficient heightor sharpness, or both, to be self-cleaning in the presence of theforese

21、eable contaminants. Other important considerations inthe selection of an abrasive treatment include bonding of theabrasive to the walkway surface base material or other meansof attachment of treatment to the walkway surface; wearresistance or resilience of abrasive material; distribution,dispersion,

22、 and density of abrasive treatment; sanitary andsanitation requirements, and others. Higher-viscosity liquids orlarger solid substances require larger grit sizes. Proper analysesare required to select the proper grit size; testing may beadvisable.6.2 Walkway surfaces and treatments with slip resista

The walkway surface of the grillebars should be slip-resistant as well.6.4 Any exposed edges of materials or treatments that createtripping hazards shall be treated as required by appropriatecodes and standards.7.
