Work Zone Safety System
The National Trench Safety “Work Zone Safety System” is a fully integrated, engineered solution to address today’s underground contractors need for a product or products to protect workers and the public in and around an excavation. The NTS Work Zone Safety System includes fall protection, access, egress and recovery product(s) designed for the unique needs and products found in today’s routine and highly complex excavations. With today’s excavation depths commonly exceeding 20’ there’s a significant exposure to contractors by employees and the public accidentally falling into the excavation. In addition the problem of worker injuries created by using ladders against trench boxes, steel sheeting, slide rail and other shoring systems is well documented as a major problem in the industry. In addition, most contractors are frustrated with the lack of a true employee fall protection, retrieval winch and davit arm system that will actually work with the various shoring and shielding products used today, which also meets the OSHA standard for such devices. The NTS “Work Zone Safety System” addresses these jobsite issues with proprietary handrails, ladder access platforms and articulating davit arms that can be used as a set or on a standalone basis.
NTS Handrail System
The NTS Handrail System is specifically designed to attach to most trench shield panels, slide rail panels and or various other forms of excavation protective systems in use today. The system is designed so that it can be attached above ground and from the outside of the trench to ensure worker safety and OSHA compliance. Once properly installed, the handrails are pinned together to create a continuous barrier along the excavation wall. The system can be quickly installed and removed without any mechanical equipment required. The system meets current OSHA standards and comes with manufactures tabulated data.
NTS Ladder Access Platform
The NTS Ladder Access Platform maintains the continuous barrier benefits found with the NTS Handrail System and provides an access and egress point that does not compromise the fall protection provided by the handrail system. The system contains a platform and ladder rest that is secured by a self-closing access gate. The NTS Ladder Platform is specially designed to attach to most trench shield panels, slide rail panels and or various other forms of excavation protective systems in use today. The system meets current OSHA standards and comes with manufactures tabulated data.
NTS Davit Arm
The NTS Davit Arm System is the final component of the fully integrated NTS Work Zone Safety System. The davit arm was designed to allow for the continuous use of the handrail system and the Ladder Access Platform. The davit arm was designed so that it could be easily repositioned and the wide range of motion provided by the articulating davit arm helps to minimize the frequency of repositioning. The system meets OSHA 1926 Subpart R, Protection Systems Criteria, (d) fall arrest systems. The winch is a fully functional fall protection device and also acts as a fully functional retrieval winch.
The NTS Work Zone Safety System is the industry’s first fall protection system designed specifically for trench and excavation work. The entire system was designed by a Registered Professional Engineer in accordance with OSHA Subpart M 1926.502(b) and has patents pending. Manufactures Tabulated Data is provided with the system to govern its use and ensure worker safety.
