The NTS work zone safety system is an integrated fall protection system designed for the trench safety industry. The system combines patented handrail, davit arm and ladder access platform components to form a comprehensive fall protection solution for contractors.
Guard Rails
All railings and components shall be capable of withstanding a force of at least 200 pounds applied to the top rail within 2 inches of the top edge, in any outward or downward direction, at any point along the top edge. Three mid-rails, screens, mesh, intermediate vertical members, solid panels, and equivalent members shall be capable of withstanding a force of at least 150 pounds applied in any downward or outward direction at any point.
Davit Arm
Davit Arm retrieval systems are used to tie off workers who are suspended below a surface. Davits can be used for raising and lowering the worker to an area below the unit. It can be mounted to a number of different support structures. Davit Arm retrieval systems are an essential part of a confined space access or rescue plan. Davit Arms are also commonly used by Emergency Response Units for rescue in confined spaces.
Ladder Safe
Ladder Safe provides safe work zone and ladder access for workers entering/exiting an excavation.
- Platform and ladder rest can be configured for virtually any size excavation
- Designed to be integrated with the NTS Handrail System to provide complete work zone handrail and access system
- Patented
