What action should you take if the tray serving cart has leaked on the floor?

The appropriate action in this scenario is to wipe up the spill and notify housekeeping for a proper clean-up. This approach addresses immediate safety concerns by removing the slip hazard created by the spilled liquid, thus protecting staff, residents, and visitors from the risk of falling.

While placing a wet floor sign can alert others to the danger, it does not eliminate the issue and could lead to accidents if someone enters the area unaware that the floor is slick. Simply notifying housekeeping is necessary, but it doesn't take direct action to mitigate the risk present at that moment. Placing a towel over the spill may absorb some liquid but would still leave an unsafe condition, as it does not fully remove the hazard nor provides adequate warning to others.

By both wiping up the spill and notifying housekeeping, you ensure that the area is made safer quickly while also addressing any lingering need for a thorough cleaning, demonstrating a proactive approach to maintaining a safe environment.
