RETRIEVAL DEVICES

From a simple manhole in the middle of a paved street to a side entry in a metal process vessel, each brand has products with specific features designed for your unique situation. We also offer other Confined Space Safety Equipment, like ventilation equipment and confined space radios, and feature confined space kits to help on the job.

Frequently Asked Questions:

What is a confined space retrieval system, and why is it required?

A confined space is defined as any area unfit for prolonged human occupancy. The space typically has limited ventilation with few escape routes. If workers detect a toxic gas, the ceiling caves in, or a flash fire were to occur, the team will need to quickly evacuate anyone inside the space using a confined space retrieval system.

Rescue equipment may include a durable tripod system for raising or lowering materials and employees in and out of the space. They are commonly used in manholes, utility lines, and spaces with narrow openings.

The emergency retrieval system is equipped with a winch or mechanical device that can support the weight of the worker. The winch will deploy a retrieval line that slowly lowers the worker into the space. Those inside the confined space should wear a full-body harness with a carabiner that then attaches to the line.

What are the safety hazards for confined space entry?

Confined spaces can contain a range of potential hazards. These spaces have limited options for entry and exit, which can reduce oxygen levels and make it difficult to breathe. Toxic gases, such as carbon dioxide, methane, and chlorine gas, may be present in the space. These are colorless, odorless gases that can be detected using a gas monitor. 

Any amount of exposure to hazardous gases is considered dangerous. If a gas is detected, the personnel will need to leave the space as quickly as possible.

Some gases are also extremely flammable. These gases increase the chances of a flash fire, especially if workers are using blowtorches and welding equipment that produces a spark. The fire can quickly spread throughout the space, forcing workers to evacuate.

Confined spaces may also be structurally unsound. Construction sites, utility tunnels, tanks, and even some basements can leave workers trapped inside the space if the exit is blocked. The ceiling may collapse at a moment’s notice. Pipes, beams, and other materials may shift in place as workers begin making changes to the space.

What rescue equipment is required for confined spaces?

Employees must wear the proper safety equipment when occupying confined spaces. Depending on the gases present, workers may need to wear a respirator that covers their nose and mouth. A multi-gas detector in the breathing zone can help to alert workers when harmful gases are present or if there’s a lack of oxygen. The detector should issue an audible, visual, and vibrating alarm to maximize personnel awareness.

There should be trained personnel standing outside the confined space, ready to raise or lower the workers inside the space at a moment’s notice. Some workers may even need to wear a helmet for fall protection and a full body harness for safe retrieval.

Everyone on the team should be trained on what to do in an emergency. Workers may need to be evacuated one by one. Employees should remain calm and adhere to the latest evacuation procedures. A permit may be required for confined space entry. Teams should also have a confined space communication system to maintain contact with those outside the space as conditions change.

How do I choose the right confined space retrieval system for different applications?

Product selection depends on your specific working environment. Consider whether personnel will enter through overhead openings, side entries, or ground-level access points. Industrial applications may require corrosion-resistant products, while construction sites need portable systems. The retrieval line attaches differently based on the entry angle. 

Match your confined space retrieval system to factors like depth, opening diameter, and whether working areas involve chemicals or extreme temperatures.
