Slip, trip and fall incidents result from a variety of dangerous conditions. A slippery surface may be caused by ice, snow, water, unsecured carpet or rug, or spilled product, (such as food, lubricant, health or beauty aid). Any kind of dangerous condition in which a person’s foot could catch or drop can cause a trip; examples include a hole or pothole, an unlevel surface or hidden obstacle. Any condition which may cause an unknowing person to slip or trip and fall is a cause of an incident.
