8、blowing,shoveling,de-icing,and/or applying sand or other abrasives.5.1.2 Reasonable effort should be made to ensure exteriorwalkway surface safety for pedestrian traffic.5.1.3 A combination of preparatory and ongoing snow andice control methods should be employed,as applicable.5.1.4 Snow and ice con
9、trol procedures should be prioritizedbased on pedestrian usage.Where feasible,parking lots shouldbe barricaded,plowed,and treated with de-icing materialsbefore permitting use.5.1.5 Snow and ice storage accumulations should be locatedto avoid obstructing drains,downspouts,or walkway drainagefeatures.
10、5.1.6 Stair systems,ramps,handrails and side rails shouldbe cleared of snow and ice before permitting their use.5.1.7 Walkway surfaces should be monitored and treated forrefreezing.5.1.8 Removed snow and ice should be placed/stored in amanner that does not create a slip hazard upon melting orrefreez
11、ing.For example,plowing snow accumulations to lowerelevations of the property or onto grassy areas may preventpotentially hazardous refreezing of melt water.5.1.9 Removed snow and ice should not be stored in amanner that creates a safety hazard for pedestrians,such asplacement that blocks a path of
12、egress.Fire hydrants andsimilar fixtures that could be covered by snow and ice shouldbe marked with reflective posts,stakes,or other distinctivemarkings.5.1.10 Special attention should be given to snow and iceclearance and control during reasonably foreseeable peakpedestrian traffic periods,includin
