Slip-And-Fall Measurements and Regulations
Static Coefficient of Friction (SCOF) is defined as follows: The ratio of the horizontal component of force applied to a body that just overcomes the resistance to slipping to the vertical component of the weight of the object or force applied.
The higher the number the lower the probability of slipper occurs. Per NFSI B101.1 SCOF > .60 is considered “High Traction”. All SlipDoctors products fall into this tier of High Traction.
Friction is the action of one surface or object rubbing against another. There are two primary types of friction: dynamic friction and static friction. Dynamic friction is
e friction between two moving surfaces or objects. Static friction is the friction between two objects that are not moving.
ANSI (American National Standard Institute) was founded in 1918 with the mission “to enhance both the global competitiveness of U.S. business and the U.S. quality of life by promoting and facilitating voluntary consensus standards and conformity assessment systems and safeguarding their integrity.” ANSI oversees the creation, promulgation and use of thousands of norms and guidelines that directly impact businesses in nearly every sector: from acoustical devices to construction equipment, from dairy and livestock production to energy distribution, and many more.
The NFSI (National Floor Safety Institute) is a 501(c) (3) not-for-profit organization. NFSI was founded in 1997 with the intention of preventing slip and fall accidents by educating the public and businesses through informative programming, research, training, and product certification. NFSI certifies flooring materials, coatings, chemical floor-cleaning products, and treatments.
ANSI and NFSI have devised various detailed standards for measuring the Coefficient of Friction (COF) of a surface.
The American with Disabilities Act (ADA) was enacted in 1990 to guarantee equal opportunities for individuals with disabilities. The ADA made it illegal to discriminate on the basis of disability in employment, transportation, telecommunications, state and local government and public accommodations. In 2003 the ADA advisory on surface conditions issued “Bulletin 4” which recommended a static coefficient of friction (SCOF) value of 0.6 for level surfaces and .8 for ramps and inclined surfaces.
The Occupational Safety and Health Administration (OSHA) was founded in 1970 with the mission to “assure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education and assistance.” OSHA does NOT currently have any published standards regarding slip resistance; OSHA inspectors can issue citations to businesses and property owners for excessively slippery floors.
