HOW THE DENNINGTON SAFETY HARNESS OVERCOMES
THE FUNDAMENTAL PROBLEMS WITH THE PRESENT TECHNOLOGY
Until recently, industry has had no alternative to the tear away Elongation Deceleration Device (EDD).
The problems with the EDD, or tear away lanyards, are three fold:
First, most lanyards are 6 ft. The additional length provided by the tear away EDD (3 ½’) will cause you to fall a total of 18 ½ feet. In other words the total length of the fall will allow you to contact the lower level of the structure you are tied to since typical buildings are built in ten foot increments! In February 1995 OSHA enacted its current fall protection standard. This regulation requires fall protection for anyone exposed to a fall of six feet or more.
To be in federal compliance using a 6 foot lanyard with the 3 ½ foot tear away, all other manufacturers instruct that you must be tied off over the top of your head. Does this place exist in your workplace? It does not for Ironworkers or persons working out of aerial lifts, etc. Is this over-your-head tie off point easily accessible? It is not in most instances without using a retractable system. Retractable systems cannot be used in normal situations. See “Truth about Retractables” page.
The Dennington Solution: The unique design of the Dennington Safety Harness allows the elimination of the tear away EDD and stops you within six feet of maximum fall distance with the use of a shock absorber which is built into the unit itself. You can therefore eliminate the over-the-head tie off point so that you can now easily be properly rigged for the first time since 1995. You now have 5 foot of working room, six foot of maximum fall descent, which enables you to do your job efficiently and still remain in federal compliance.
The Second deficiency relates to retrieval situations. The tear away EDD's lanyard is connected to a D-ring in the middle of the back. This causes an unconscious fallen worker to be in a slumped position at the end of the fall. The slumped position makes retrieval hazardous, particularly in confined space. A slumped position puts the worker at serious risk of either head or back injury.
The Dennington Solution: The unique design of our Dennington harness allows for recovery in a vertical position by virtue of the three point balancing system. This will significantly reduce the retrieval time and potential for suspension trauma associated with hang time. It facilitates for a much quicker and easier retrieval process.
The Third deficiency relates to what we call "the slamming effect". This is what happens when you fall with a "tear away" system and/or hit the end of a straight lanyard at the end of a fall. When a worker falls with a "tear away" lanyard, a whipping motion occurs that is likened to that of cracking a whip. This motion can slam the worker back into the structure which he is tied off to at a significant force, causing unnecessary injuries or death. For example, when a worker falls off a structure he falls sideways or head first. When he hits the end of the lanyard he will flip over which greatly accelerates the slamming effect like cracking a whip.
The Dennington Solution: The Dennington harness absorbs the downward inertia of the victim, not transferring it to lateral impact into the structure used as an anchorage point. It is during the "slamming" stage of falls where numerous head, back and neck injuries occur. Furthermore, there is significantly less shock on the body as demonstrated in our video by Mark Dennington as he repeatedly jumps off a seventy foot tower.
Our experience has shown that after seeing our harness demonstration and video, there will be no question which harness you would choose to wear in a fall situation. Call us today for more information or for 3D Virtual Reality training.
