Precautions and protection
Tiled floors are not 'resilient'. In other words, they are only moderately shock proof. Every effort should be made to prevent heavy objects from dropping on tiles floors. Areas on which objects are more likely to be dropped or on which they drop more frequently should be protected with mats. For example, in the kitchen, the area in front of the oven and sink should be protected.
