This is why all West Coast Chemical Corporation hard surface floor care products exceed industry standards for slip resistance. All finishes are tested for slip resistance to insure the highest quality and slip resistance possible. Slip resistant industry standard for floor finish and coatings are measured by utilizing the James Machine Testing method. A minimum of .5 is required. Our Safety Trac system which includes our Safety Traction and Hi-Lite cleaner is a positive emulsion detergent which is concentrated and pleasantly scented. Hi-Lite is an efficient cleaner for all types of general cleaning and for removal of hard water haze and residual left behind by other chemicals. Hi-Lite increases the coefficient of friction or slip resistance when applied over our floor finishes.
Static Coefficient of Friction
“Slip resistance is based on the frictional force necessary to keep a shoe or crutch tip from slipping on a walking surface under conditions likely to be found on the surface…. The Static coefficient of friction, which can be measured in several ways, provides a close approximation of the slip resistance of a surface.” These statements were taken from the ADAAG Appendix. Static coefficient of friction (SCOF) is measured by determining the amount of force required to create the movement of an object across a surface. The controls include a specified weight, with a surface, or “sensor”, such as leather, rubber, or neolite, representing the bottom of shoes, in contact with the floor material to be tested. The measurement of the pressure that initiates the movement is recorded, this being the static coefficient of friction. The assumption is that the more pressure required to pull the weight, the more resistance exists on the floor, resulting in a more slip resistant surface.
The James Machine
The James Machine test was developed in the 1940’s, and was specified by Underwriters Laboratories as the test for SCOF of floors treated with a floor polish. A minimum value of 0.50 was established as the criteria to bear a UL seal. This test uses leather as its sensor, and is measured in a dry state only. The theory behind testing only a dry surface is that a wet floor is the result of poor maintenance, and a wet floor is a slippery floor. The Chemical Society Manufacturers Association, whose membership includes many of the leading floor finish manufacturers, also endorses the use of the James Machine for slip resistance testing. OSHA also accepts 0.50 as the minimum requirement for slip resistance, as does the Federal Trade Commission.
Specify floor maintenance procedures
Floor maintenance is an extremely important factor in determining slip resistance. A wet floor usually creates a slip hazard. In areas such as restaurants and food service areas, discuss the concept of immediate removal of spilled food or drink. In floor areas adjacent to the street, such as retail stores or lobbies, specify walkoff mats. In addition to removing water from the bottom of shoes, these mats will also remove the dirt or sand that can severely damage the floor’s surface. Additional mats should be placed near the entrance during rain or snow conditions. Regular floor maintenance will also result in the removal of dirt and particularly dust, a common creator of slippery floors. Proper floor maintenance also requires that maintenance chemicals be reapplied on an “as needed” basis. Make sure that cleaning chemicals are compatible with sealers. In addition, certain waxes can create a slipping hazard.
