During snowy and icy conditions, contamination might be difficult to discover. Snow and ice could hide dirt from being discovered, but it could also contain dirt that when melting, risk cross contaminating nearby cargo or the vessel cargo hold.
Whenever possible, excessive amounts of snow should be removed before loading. Same goes for cargo under repositioning.
Removal:
Snow should be removed with a soft brush. Ice on windscreens should be removed only with a plastic edged ice-scraper, special care should be observed when removing ice close to rubber moldings. Severe frost on the windshield can be removed with vehicle’s window heater. Frozen wiper blades should only be released manually.
