Slip and fall, in United States tort law, is a claim or case based on a person slipping (or tripping) and falling. It is a tort, and based on a claim that the property owner was negligent in allowing some dangerous condition to exist that caused the slip or trip.
Property owners generally have two basic defenses to Public liability slip and fall claims:
Because of a general perception that slip and falls are at least partly the fault of the person injured, slip and fall injuries are usually worth less than injuries from other types of torts.
For slip and fall investigations, the incident walking surface slip resistance can be measured. The surface can be tested to identify if it is above or below accepted levels of slip resistance thresholds.[1]
Special instruments are available to measure slip resistance. The pendulum tester is a national standard for pedestrian slip resistance in 48 nations on four continents, and has been endorsed by Ceramic Tile Institute of America since 2001.[2] A common reference for safety is that the Pendulum Test Value should be 36 or higher under the conditions of use (wet, dry, etc.). The pendulum is also used in a test for Sustainable Slip Resistance.
The BOT-3000 is capable of measuring wet static and dynamic coefficient of friction. The static test is specified in ANSI method B101.1[3]
Static coefficient of friction is also measured by ASTM method C1028-07. However, many forensic experts believe that this method is not adequate for assessing safety.[4] [5]
The English XL Slip Meter, also known as a VIT (Variable Incidence Tribometer) is a portable "slip tester", designed to test the "slip index" on various walking surfaces, level or incline (even steps), under dry and wet (or otherwise contaminated) conditions by mimicking certain pedestrian bio-mechanical parameters.[6] The English XL test method has been described by ASTM method F1679, but was later withdrawn with no replacement, and so no longer exists.[7]
