Products For Confined-Space Entry, Liquids Flow By-Pass And Manhole Repair INTRUDER® The patented INTRUDER Confined-Space Entry Access / Rescue and Retrieval System by Miller is designed to provide safe entry into sewer manholes as well as gas, electric, telephone and other man-entry structures. It provides a ladder with strong, secure steps and access at or above ground level. The portable INTRUDER system can be quickly and easily assembled. The ladder, attached to the frame placed around the man-entry structure, is completely secured and self-supporting, not resting on the slippery bottom of the manhole. Optional fall protection / rescue / retrieval systems are available, as well as flags and strobe lights. Safe-Passage® The patented Safe-Passage Flow-Through By-Pass Ramp System is designed to replace troublesome sewage by-pass hoses, commonly used to route flow around wastewater pipeline repairs. The system provides a trouble-free method of running by-pass lines over driveways, streets and other vehicle routes without impeding traffic or risking a break in the hose that could spill raw sewage into the street. These high-strength conduits are available in either aluminum or steel construction. The 12-foot long ramp sections are portable for easy movement from one job site to another. The system is designed so that any number of Safe-Passage sections can be bolted together using specially designed flanges.
