Inside a store, if there are slipping hazards from slippery floors, broken bottles of liquids that can cause someone to slip, the store owner is responsible for cleaning up these hazards right away. In some stores, the employees are trained that when they see a slipping hazard, that they follow a protocol of:
Grabbing a yellow hazard sign and putting it near the slippery area
Calling maintenance for the store to come and clean up the mess immediately.
Having an employee stand near the spill to direct customers safely around the area.
Waiting until the area is cleaned up before allowing customers to frequent the area again for shopping.
