ANSI / NFPA

ANSI A1264.2

The A1264.2 sub-committee began writing a standard with the intent of reducing falls due to slippery conditions which in are some way preventable in the workplace. The three basic areas of the standard are:

  1. Provisions for reducing hazards
  2. Test equipment
  3. Slip resistance criteria

The first area constitutes the largest part of the standard and addresses: Footwear applications and considerations, Mats & Runners, Housekeeping, Warnings, Symbols, Controlled Access, Selection and/or treatment.  The test equipment portion essentially refers to ASTM standards and test methods.

NFPA 1901

The National Fire Protection Association standard 1901 entitled Standard for Automotive Fire Apparatus has a specification in section 13-7.3 for slip resistance. It states that all external surfaces used for walking and standing shall have a slip resistance of at least 0.68 when wet as tested by the English XL VIT (per ASTM F1679 Standard Test Method for Using a Variable Incidence Tribometer), or at least 0.52 when wet as tested by the Brungraber Mark II PIAST (per ASTM F1677 Standard Test Method for Using a Portable Inclinable Articulated Strut Slip Test). Internal walking and standing surfaces must have a slip resistance of at least 0.58 per the English XL VIT or 0.47 per the Brungraber Mark II PIAST.

  • SlipNOT® exceeds the recommended coefficient of friction values set by the NFPA.

OSHA

OSHA requires the use of slip resistant surfaces in several locations in their standards.

29 CFR 1910.24(f)

“Stair treads.” All treads shall be reasonably slip-resistant and the nosings shall be of non-slip finish. Welded bar grating treads without nosings are acceptable providing the leading edge can be readily identified by personnel descending the stairway and provided the tread is serrated or is of definite non-slip design. Rise height and tread width shall be uniform throughout any flight of stairs including any foundation structure used as one or more treads of the stairs.

A proposed standard for Subpart D does make a reference to a 0.5 requirement for coefficient of friction. However, this standard was never promulgated as a final rule. Some product manufacturers point to this proposed standard as a rule to which employers must comply.

The most significant regulation affecting slip resistance can be found in the OSHA construction standards as they relate to steel erection.

1910.68 Subpart F – Powered Platforms, Manlifts, and Vehicle-Mounted Work Platforms

(c)(3)(v)

“Surfaces.” The upper or working surfaces of the step shall be of a material having inherent nonslip characteristics (coefficient of friction not less than 0.5) or shall be covered completely by a non-slip tread securely fastened to it.

1910 “Walking and Working Surfaces and Personal Protective Equipment; Notice of Proposed Rulemaking

This proposed rule issued by OSHA included a non-mandatory appendix specifying a minimum slip resistance of 0.5 as reasonable slip resistance performance. Although they are still on the books, none of the proposed revisions to subpart D has been promulgated at this time.

  • SlipNOT® products have a coefficient of friction that is greater than or equal to 0.85, exceeding all OSHA recommendations.

ADA

Americans with Disabilities Act (U.S. Department of Justice)

A4.5 Ground and Floor Surfaces.

A4.5.1 General. People who have difficulty walking or maintaining balance or who use crutches, canes, or walkers, and those with restricted gaits are particularly sensitive to slipping and tripping hazards. For such people, a stable and regular surface is necessary for safe walking, particularly on stairs. Wheelchairs can be propelled most easily on surfaces that are hard, stable, and regular. Soft loose surfaces such as shag carpet, loose sand or gravel, wet clay, and irregular surfaces such as cobblestones can significantly impede wheelchair movement.

Slip resistance is based on the frictional force necessary to keep a shoe heel or crutch tip from slipping on a walking surface under conditions likely to be found on the surface. While the dynamic coefficient of friction during walking varies in a complex and non-uniform way, the static coefficient of friction, which can be measured in several ways, provides a close approximation of the slip resistance of a surface. Contrary to popular belief, some slippage is necessary to walking, especially for persons with restricted gaits; a truly “non-slip” surface could not be negotiated.

The Occupational Safety and Health Administration recommends that walking surfaces have a static coefficient of friction of 0.5. A research project sponsored by the Architectural and Transportation Barriers Compliance Board (Access Board) conducted tests with persons with disabilities and concluded that a higher coefficient of friction was needed by such persons. A static coefficient of friction of 0.6 is recommended for accessible routes and 0.8 for ramps.

It is recognized that the coefficient of friction varies considerably due to the presence of contaminants, water, floor finishes, and other factors not under the control of the designer or builder and not subject to design and construction guidelines and that compliance would be difficult to measure on the building site. Nevertheless, many common building materials suitable for flooring are now labeled with information on the static coefficient of friction. While it may not be possible to compare one product directly with another, or to guarantee a constant measure, builders and designers are encouraged to specify materials with appropriate values. As more products include information on slip resistance, improved uniformity in measurement and specification is likely. The Access Board’s advisory guidelines on Slip Resistant Surfaces provides additional information on this subject.

  • SlipNOT®’s coefficient of friction (0.85 or greater) exceeds the recommendation of ADA (0.6 for flat surfaces and 0.8 for ramps).

Industry Applications

Fabricating Instructions

SlipNOT® Metal Safety Flooring products can be treated similar to their smooth plate counterparts. Material can be sheared, flame/torch cut, laser cut, water-jetted, plasma cut or welded, either directly or from the opposite side, without harming the SlipNOT® surface. SlipNOT® can also be drilled and countersunk. The SlipNOT® process results in a hardened surface between 55 – 63 on the Rockwell “C” Scale.

  • Drilling/Punching
    steel

    SlipNOT® material can be drilled and countersunk. Generally, due to the resulting surface hardness, pre-drilling material prior to the SlipNOT® application is recommended. Pre-drilled holes, countersinks, and counter bores are protected from the SlipNOT® process so screws/bolts will sit flush. Due to the surface hardness, if fabrication is done after SlipNOT® application, additional time and tooling costs should be figured into estimating and labor costs.

  • Shearing
    steel

    Due to the unique random stacked hatch matrix of the SlipNOT® surface, plates can be sheared. It is recommended that SlipNOT® material be flame, plasma, laser or water-jet cut to save wear and tear on tooling. Plates can also be sheared from the non-slip side to help minimize dulling of the shear blades, however, the roughened, hardened SlipNOT® surface can scratch shear tables.

  • Flame/Plasma
    steel

    The unique SlipNOT® surface is bonded to substrates at over 4,000 psi and cutting with flame / plasma is no different than with smooth plates. This is the preferred method for fabricating SlipNOT® material. The random matrix surface will not flake or delaminate along burn lines and will not be harmed by any standard burning operation.

  • Laser Cut
    steel

    The random stacked hatch matrix surface of the SlipNOT® will add approximately 0.020” – 0.030” to any given substrate. These materials will not harm the optics of laser cutters so SlipNOT® materials can be treated exactly the same as non-SlipNOT® treated pieces. The laser will not harm the SlipNOT® surface in any way and the SlipNOT® surface will not damage any laser equipment.

  • Welding
    steel

    SlipNOT® is an all-metal, grit-free surface. Welding is performed exactly the same as required for the non-SlipNOT® treated counterparts. No special requirements are needed. Heat distortions and discolorations from any welding will be transmitted through the SlipNOT® surface as well and should be taken into account if aesthetics are critical to your project. Mounting angles or other such material can be pre-welded to materials and used as weld points during the installation process. This will minimize the chances of surface blemishes.

  • Surface Masking/Detailing
    steel

    SlipNOT® is a molten metal plasma stream despoliation and areas can be masked / protected from surface coating. In cases of stair treads, risers and nosing are masked and only the tread surface itself receives the SlipNOT® application. Logos, words, or patterns can also be created within the SlipNOT® surface application however, there can be additional costs associated with these procedures. For welded installations, small borders can be masked for easier metal working.

Galvanizing Guidelines

steel

Care must be taken in the pickling portion of the hot dipped galvanizing process as the SlipNOT® surface may lift off if pickling times exceed recommendations. Care should also be taken when rack loading to allow for sufficient spacing between items so that the heat of the pickling process does not create “hot spots” within the pickling tanks and potentially damage the SlipNOT® surface. Listed below are suggestions and guidelines for galvanizing SlipNOT® steel products: SlipNOT® provides all galvanized steel products in accordance with ASTM A123

RECOMMENDED

  • Using ambient temperature hydrochloric acid
  • Acid pickling times should not exceed ten (10) minutes for ambient temperature hydrochloric acid solutions
  • Maintaining a constant temperature of 830° – 840° while in the galvanizing zinc bath
  • Shot blast or sand blast any additional steel such as stringers, support angles, stiffeners, etc. prior to the galvanizing process along with being de-scaled and rust free
  • Material should be kept inside and wrapped to prevent surface rust from forming

NOT RECOMMENDED

  • Do not leave material in acid pickling process for more than ten (10) minutes
  • Do not use a heated sulfuric acid solution immersion for more than three (3) minutes
  • Do not use an inconsistent temperature while in the galvanizing zinc bath
  • Do not provide greasy, scaly, rusty material to the Galvanizer
  • Do not allow exposure to the elements that can create surface rust

SlipNOT® strongly recommends that hot dipped galvanizing be provided by us or contracted directly with Voigt & Schweitzer Galvanizers LLC. For a local contact familiar with proper handling of SlipNOT® products in Redford, MI, see below:

If the SlipNOT® surface is galvanized by a 3rd party the above mentioned guidelines must be observed. The W.S. Molnar Company is not liable for damage to the SlipNOT® surface by 3rd parties. If galvanized incorrectly, the SlipNOT® surface can be compromised. If you have questions or require galvanized samples to test, please call (800) 754-7668 or (800) 754-7668.

SlipNOT® is not responsible for costs associated with replacement or repair of material fabricated, including but not limited to drilling or welding after galvanizing. Also, pieces damaged in material handling must be field repaired. Failure to adequately repair and protect compromised surfaces will result in pre-mature failure of the SlipNOT® and galvanized surfaces. SlipNOT® is not responsible for surface damage caused by either deliberate or incidental means.

Care & Cleaning

SlipNOT® products can be cleaned by most standard agents, please contact a sales representative for more information.  Clean slip resistant products on a regular basis to prevent any build up or residue that can cause the peaks and valleys to smooth over.  Small debris can be dislodged easily with compressed air or a soft bristle brush.  If the SlipNOT® material is subject to excessive greasy or oily environments, significant grime or sludge can fill in the valleys between the peaks of the SlipNOT® surface (in effect smoothing over the SlipNOT®), it requires cleaning with a stiff bristle brush or power washing to bring back the optimal surface texture.

 

Care for Steel Products

image
  • Mill finish steel SlipNOT® products will rust if exposed to moisture or humidity.
  • Material should be primed and painted or hot dipped galvanized to prevent corrosion.
  • Hot dipped galvanizing is the ideal method for corrosion resistance.
  • Use a power washer and stiff bristle brush to remove any debris lodged in peaks and valleys. Note: steel products should be protected due to corrosive nature.
  • Organic based stains, such as grease or oil, can be removed with standard organic solvents. The most common is commercially available brake cleaner but any organic solvent will most likely work. Some scrubbing may be required to remove grease buildup.
  • Detailed information available upon request.

Care for Stainless Steel Products

image
  • Be aware that certain organic enzyme and alkaline based cleaning agents can blacken the stainless steel which will bleed through the SlipNOT® surface layer as well
  • The stainless steel SlipNOT® is our most chemically resistant product and withstands nearly all other cleaning or environmental situations from alkaline to acidic. Also, the stainless steel products can be passivated to remove welding discolorations like stainless steel.
  • Organic based stains, such as grease or oil, can be removed with standard organic solvents. The most common is commercially available brake cleaner but any organic solvent will most likely work. Some scrubbing may be required to remove grease buildup.
  • Use a power washer and stiff bristle brush to remove any debris lodged in peaks and valleys.
  • Should the stainless steel product be contaminated with surface rust, it is generally recommended that this be removed with diluted muriatic acid. Concentrations should not exceed 1 part acid to 1 part water.

Care for Aluminum Products

image
  • Material should be handled with care.
  • Aluminum is a soft alloy that can be damaged if not handled properly.
  • Organic based stains, such as grease or oil, can be removed with standard organic solvents. The most common is commercially available brake cleaner but any organic solvent will most likely work. Some scrubbing may be required to remove grease buildup.
  • SlipNOT® recommends that a stiffened bristle brush used in conjunction with a power washer – too much pressure can lead to degradation of the SlipNOT® surface.
  • Standard Aluminum cleaning products such as Tri-Sodium Phosphate solutions work well.
