>  Confined Space Entry/Rescue  >  Overview

​​​​​​​​​​

If you have the guts to go in, we'll get you out!

In confined space entry and confined space rescue situations, your safety equipment must operate quickly and flawlessly. That's why 3M developed an extensive line of high quality, rugged rescue and retrieval systems that meet a variety of confined space safety needs, plus offers customized solutions.

Our confined space safety systems have delivered decades of trusted service and meet applicable industry standards, so it's no surprise that our confined space equipment is the first choice of safety engineers and site directors.​

Confined spaces vary in size, shape and location and there isn't a standard or typical application. A confined space safety system can usually be divided into either a "vertical" entry type system or "horizontal" type.

If entering confined spaces such as a manhole on a street vertical confined space rescue equipment is needed. Some confined spaces require entry from the side such as a tank, and for these you'll need a side-entry or horizontal type confined space safety equipment.

Product Lines

  • ​The Advanced Series Hoist Systems are designed for manhole and confined space entry/retrieval applications. These units are constructed of lightweight materials including high-strength aluminum. The davit pivots for ease-of-rescue and has adjustment for overhead clearance restrictions. The lower base adjusts to fit most standard entries. Many other portable and fixed bases are available to suit any jobsite need. If additional height is required, check out our lower mast extensions.​​


  • ​Variable offset davits are designed for use where multiple offset masts are required and may be equipped with front mounted and/or back mounted winches or SRLs. Numerous bases are available in portable or permanent styles to accommodate almost any application. Options include free-standing, bolt or weld in place, counterweighted and even hitch-mount style bases.​​​


  • ​Advanced Tripods are constructed of lightweight tubular aluminum with a rugged steel head assembly. The UCT series tripods can be combined with up to three pulleys to accommodate a variety of winches and fall arrest devices to meet a wide range of confined space entry/retrieval and rescue requirements. Quick release pins positively locate components at all adjustment points for tool-less set-up and adjustment.​​


  • ​The mechanical device is one of the most critical parts of the rescue system. It provides the means to retrieve an incapacitated worker to safety. Lifeline type and length are just a few of the options. In some situations, a secondary or back-up system is required.​ Typical mechanical devices include man-rated winches and 3-way self retracting lifelines with both fall protection and emergency rescue winch capabilities.​​


  • The system provides protection and complete mobility for three workers on top of transformers or other types of vertical platforms with potential fall hazards. The system features a telescopic design and 3 swiveling anchor points providing up to 3 workers with 360 degrees of protection and mobility. Portable and fixed bases as well as a davit arm option provide complete jobsite versatility.​​​​​​​


  • ​Attaches with a carabiner on the universal bracket to a suitable anchor point, allowing you to work in any direction from any angle. It has a unique swivel head that rotates 360 degrees, providing flexibility in both vertical and horizontal confined space entries. Two systems that adjust from either 4 ft. to 7 ft. (1.2 m - 2.1 m) or 6 ft. to 10 ft. (1.8 m - 3 m) are available for jobsite flexibility and to better position the attendant in close working quarters.​​


  • The Side Entry System is designed for ​horizontal entries with vertical positioning or retrieval required inside the space. The system is available in two configurations: permanent and portable. The permanent system utilizes a fixed base and extension post, while the portable system utilizes an external adjustable tank collar for adaptation to different manways. Both types of systems feature flexible setup options and a fully articulating boom system. They are fully adaptable to an infinite number of manway designs and surrounding configurations.​


  • ​The Tank Pod is designed to mount to tank manways with existing hardware for securing hatch covers. It mounts to manway flanges on bolt circle diameters from 19" to 36" (48.2 cm - 91.4 cm), with studs from 1/2" to 3/4" (1.2 cm - 1.9 cm) national coarse type. Three independently adjustable legs accommodate flange inclinations to a maximum of 45 degrees. The unit can be set up in an overhead clearance of only 25" (63.5 cm). It can be fitted with a variety of winches, ladder systems and fall arrest devices to meet application requirements.​​
