Stopping the Drop

February 14, 2017

Forrest Hester, CEO of Tutus, LLC, is a former industrial electrician who established Tutus in 2015 to protect himself and his fellow co-workers through the development of Dropped Object Prevention Solutions (DOPS) system.


One piece of debris or the untethered hand tool left sitting on the control panel of the platform could potentially alter a company and an individual’s life to its very core. The system’s covering of the platform entry secures dependably and allows the operator to move in and out of the lift with ease, while still meeting American National Standards Institute (ANSI) standards for panel fill strength. The DOPS design also allows the enclosure to be placed into a half configuration from inside the lift at height, while still providing the same level of protection needed for the work being performed. The base includes a strong coil zipper to access trapped material, which makes it easy to clean between tasks.


DOPS™ system is compliant with the following standards for a safe workplace environment.

· ANSI Standard MH28.3 subsection 8.3.2; Steel platform mid-rails and panel-filler strength.

· OSHA Standard 1926.451(h)(1) & (2) and (3); To protect employees from falling hand tools, debris, and other small objects, install toe boards, screens, guardrail systems, debris nets, catch platforms canopy structures, or barricades.

· OSHA Standard 1926.759(a); Securing loose items aloft. All materials, equipment, and tools, which are not in use while aloft, shall be secured against accidental displacement.

· OSHA Standard 1926.451(f)(13); Debris shall not be allowed to accumulate on platform.

· OSHA 1915 Subpart I App A1; Controlling hazards. (6) Sources of falling objects of potential for dropping objects.

Structural Effects of Wind Loading

February 21, 2017

University of Hartford College of Engineering, TUTUS Case Study

TUTUS Dropped Object Protection Solution: Structural Effects of Wind Loading

The University of Hartford College of Engineering, under the direction of Adjunct Professor Allen Penda, and a graduate student staff, developed a test program specifically for TUTUS LLC as a case study of their new DOPS safety system – Dropped Object Solutions, a tool and debris containment wrap used on aerial lift vehicles. DOPS is a one-piece safety product made from small mesh netting, designed for field assembly using loop fasteners and one zipper. The assembled DOPS creates a re-usable five-sided enclosure that wraps around a work platform’s existing steel framework. As expected, the netting is prone to some degree of wind loading. Just how much was an unknown that needed to be solved. This is where the University of Hartford case study begins.

Background

The TUTUS DOPS began with a fast-paced time line of ideas, development, testing, and prototype deployment – in two short years. DOPS founder and president Forrest Hester developed DOPS as an invention of necessity. As a trade worker in the gas and oil business of Texas and familiar with mobile aerial lift work platforms, Forrest was aware of the unaddressed need to keep tools and material contained in a small and frequently congested work area.


Often working with what can be sourced at a job site, Forrest like many others, would wrap their aerial lift platform with readily available extruded plastic mesh, commonly used for light duty containment and perimeter marking. Assembled with zip ties, tape and rope, the wraps were one time use and were of dubious performance to contain much of anything.


Sketching and designing from home, and with the help of a sail maker, the idea grew into a series of workable prototypes. To bring the idea to production levels, Forrest reached out to a northeast safety net manufacturer, InCord. Together with a larger collaboration of ideas and assembly methods, the first production DOPS was assembled.

Case Study

The UH case study began with a simple outline:

• Understand the design requirements, and the need for wind load testing.

• Research existing information regarding wind load on netting.

• Develop a test plan to evaluate wind load induced forces on the sample product.

• Conduct wind load testing and compare the results to expected results.

• Relate wind load results as a cumulative to known limitations of a relevant aerial lift vehicle.

• Relate results to Industry Safety Standards.

• Present conclusions and recommendations based on results and analysis.

Research

Three different materials supplied by manufacturer InCord were first analyzed and then electronically modeled and tested using existing case studies regarding porosity and drag coefficient for screens. This became the basis for later validating their test method as it related to synthetic netting.


Predications were made from calculated and available research to measure a pressure drop across the netting as it equates to an applied pressure – wind load, that is calculated by multiplying the pressure drop by the netting area.

Wind tunnel testing at the UH test lab was performed and compared to calculated data. The results were nearly the same, validating the test method within six percent.

Analysis and Summary

The wind load testing up to 90 mph on three different materials produced results that were within the design requirements for DOPS. Each material had distinct characteristics, and each was proven suitable for use as standard and alternative material with the DOPS design.


With solid test analysis, TUTUS could determine the safe working limits for each manufacturers’ mobile aerial lift platform that might use a DOPS platform wrap.

To date, more than two-dozen mobile aerial lift platforms from three manufactures have been studied and matched with a TUTUS Dropped Object Protection System. Within 2017, the new aerial lift platform safety system will hopefully be deployed to worksites across the nation – saving lives and protecting property.

SkyNet™ Work Platform Netting

March 15, 2017

The ability to move freely beneath a stadium ceiling multiple stories above the ground seems awkward at best, considering high places are out of the reach of most work scaffolding and bucket lifts.


And what if you could install a walking/working floor just below the ceiling without the use of metal fasteners, drilling or modifying the existing structure?


It might seem the correct answer would be walking on air, but close – it’s called a work-platform net; a floor wide temporary walking/working platform made entirely from high strength synthetic netting and tensioned web straps.


The work-platform net is designed to allow trades without rope access knowledge to work safely in areas that would otherwise be inaccessible to conventional means of access.


Work-platform nets have become a standard for high access work in Europe and are now being used in North America for high rise construction and stadium work.

TUTUS, LLC an authorized distributor of InCord safety net products, offers the new SkyNet™ Work Platform Netting, a revolutionary new solution for working at heights where scaffolding and aerial lifts may not be practical. Utilizing a net and tension strap design, SkyNet™ provides unlimited mobility across the entire tensioned working surface.


Work-platform nets are deployed and easily moved and anchored between a framework of beams or other solid structures. Tensioning web straps running through the structural net like a grid maintain a flexible yet stable walking surface. Tools and machines may even be placed on the net within given restrictions.

Walking and working on work platform net is very easy with little practice and allows for greater freedom of motion for crew as opposed to narrow scaffolding or a bucket lift. When you set foot onto the net, it will sag slightly with your weight. Once accustomed, walking and working with others on the platform net provides complete freedom of motion so that you may concentrate on the work at hand.

SkyNet™ is a high strength work-platform net made in the United States by InCord, the leading experts in safety nets and fall protection. SkyNet™ is built to EU Standards EN 1263-1 Class B1 Standard and complies with ANSI test methods for strength under load. SkyNet™ is sold through authorized distributors and may only be site installed by qualified and trained personnel.


In accordance with regulations, work-platform nets are used in work places where specific conditions and safety measures must be observed. Vertical barrier nets are commonly used on exposed ends, creating a caged work area.
