3M 8308006 Confined Space Entry System 50 Ft

Product Description

The 3M 8308006 is a complete confined space entry and retrieval system designed for workers who require compliant vertical access and fall protection in permit-required confined spaces. The kit combines an 8-foot aluminum tripod with telescoping, adjustable locking legs, a 3-way self-retracting lifeline (SRL) with integrated retrieval winch, and a stainless steel cable lifeline measuring 50 feet in length. A dedicated pulley routes the winch lifeline for controlled entry and retrieval, and a mounting bracket secures the SRL to the tripod. The system ships as a single unit at 104.65 pounds and is intended for use by qualified safety personnel and confined space entry teams.

This system is suited for industrial, municipal, and utility applications where workers must enter manholes, vaults, tanks, silos, or similar confined spaces. The aluminum tripod provides a stable anchor point over the entry opening, while the self-retracting lifeline with retrieval winch allows the attendant to lower, hold, or retrieve the entrant without requiring a second mechanical device. The compact and durable design allows the system to be transported to multiple job sites. It is appropriate for use in water treatment, wastewater, petrochemical, construction, and general industrial environments where confined space regulations apply.

Installation Notes

Setup and operation must be performed by a competent person as defined by applicable OSHA confined space entry regulations (29 CFR 1910.146 for general industry). Position the tripod legs fully extended and locked on stable, level ground centered over the entry point before loading the lifeline. Inspect the cable lifeline, SRL mechanism, and all connectors before each use and remove the system from service if any component shows wear, deformation, or corrosion. Do not exceed the rated load capacity of any individual component.
