California shop owners know just how dangerous a simple wet floor can be. If a shopkeeper don't take proper precautions to handle a spill and warn for areas that are slippery or wet, they could quickly find yourself facing legal rammifications.
CleanFreak.com lists the proper wet mopping procedures, to keep both shopkeepers and customers safe. This includes prepping the area with wet floor signs or even cording it off, if necessary. It's also beneficial to dust the area that needs to be mopped first. This will remove large chunks of debris that could otherwise clump up and dry. Not only will this defeat the purpose of cleaning the area, but it can also create tripping hazards. Finally, after mopping, warning signs should be left up as long as it takes for the floor to dry. Tripping hazards like the mop bucket or mop itself should be removed.
Flagging Direct states that these general rules need to be followed for any wet area on the floor. Rain may also cause these issues, or spills from hoses, buckets, sinks, or other sources of water. If a store is dealing with puddles that cannot be easily cleaned, safety warning signs are needed. Even if the spills can be mopped up, having a wet floor sign might still be beneficial. If possible, spills should be mopped quickly to minimize potetial dangers.
Overall, when dealing with wet floors, the source of the wetness should be dealt with immediately. The wet spot on the ground should also be cleaned up quickly, and ample warning must be given to protect the customers from slipping and coming to harm.
