D - Descent and Rescue

View All Products

Employers must have a rescue plan that either provides the prompt rescue of employees in the event of a fall or ensures that employees are able to rescue themselves. Executing this plan may require the use of a rescue system designed for the application.

What kind of descent and rescue system do I need?
  • Rescue and Descent Devices

    These devices include ascenders and descenders that help get workers who are experiencing a problem back to a safe level safely, either by themselves or through the assistance of rescue personnel.

  • Confined Space Entry and Retrieval

    When entering a confined space, whether vertical or horizontal, special equipment can be used to aid in rescue and recovery. This is especially important in restricted or confined quarters where reaching a worker may be a challenge.


Rescue and Descent

Considerations when choosing rescue and descent systems

In addition to technical considerations, consider the amount of training required to use a piece of of safety equipment properly and effectively. In general, automatic type descent devices require much less training than user controlled systems, but also are less adaptable to multiple tasks. Consider whether the device needs to be intuitive and instantly useable by anyone, or if specific personnel need to be trained at rescue tasks for the jobsite.

  • Worker suspended from controlled descent device

    Automatic, user or co-worker controlled descent

    Automatic evacuation and emergency escape devices require the least amount of training and knowledge by the user. Some systems allow the user to control their own descent or allow a co-worker to control the descent for added flexibility. A single rescue system may not fit every scenario, some systems are easy to use for one application, while others require more skill but can be adapted for use in multiple situations.

  • Worker rescuing co-worker at height with controlled ascent device

    User or co-worker controlled ascent

    In addition to descent capabilities, some rescue systems also incorporate the ability to raise the user or victim. This function is often needed in scenarios where a worker must be rescued by another worker, typically called "pick-offs." The rescuer descends to the fallen victim, connects to the victim's system and then raises the victim slightly to enable disconnection of the victim's fall arrest system, before descending with the victim to the lower level to complete the rescue.

  • Worker suspended at end of long cable from wind turbine

    Maximum height of operation

    Close attention must be given to selecting the appropriate system that can accommodate the height of rescue or descent needed. Systems typically have a maximum usable height based on design and performance. Also consider the overall size and weight of your complete system, and the type and style of lifeline.

  • Two rescue workers and injured worker in a litter suspended from rescue device

    Maximum number of users

    Systems can typically accommodate either one or two users (at the same time). This becomes extremely important if the system needs to be used for evacuation, or if it must be used for rescue of an unconscious worker. If rescuing a co-worker in a "pick-off" type application, the system must be able to support both the rescuer and the victim.

Confined Space Entry and Retrieval

How to decide what confined space equipment you need

Confined spaces vary in size and shape and your confined space system must be adjustable and adaptable. Pay close attention to the maximum and minimum hole size and shape that you need to access, and choose a system that can be flexible.

  • Worker operating horizontal confined space entry device at opening in side of large tank

    Vertical or horizontal entry

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

  • Rescue workers operating vertical confined space davit

    Versatility and adaptability

    One-piece tripods are extremely easy to use and set-up and fit a variety of applications. Multi-piece davit systems are often more complex, but also offer more versatility with various arm sizes, and base options.

  • Workers demonstrating portable confined space retrieval tripod

    Portable or permanent system

    Temporary jobs require lightweight and easy-to-use portable confined space systems that can be moved from one location to another. If a hazardous work area is accessed often, such as a vat or tank, a davit system with a permanently mounted base may be the best option.

  • Close up of mechainical lifeline winch

    Mechanical systems

    Lifeline type and length are just a few of the options to consider. Typical mechanical devices include man-rated winches and 3-way self-retracting lifelines with both fall protection and emergency rescue winch capabilities. In some situations, a back-up system may be required.

  • Workers operating winch on vertical retrieval davit

    Ease-of-use

    Your systems must provide you with the ability to handle a crisis simply, efficiently and immediately. During an emergency, time is of the essence. Choose our high quality systems to ensure optimal performance when it is needed the most.

  • Vertical davit installed at railing of suspension bridge

    Strength

    Your system must be rated for your application, such as fall arrest, rescue, man-riding or material handling. Choose one that maximizes strength and minimizes weight. Versatility in this area is often a high priority so your system can accommodate different scenarios in your work environment.

  • Ladder system installed in vertical confined space access port

    Durability

    All system components must be made from quality materials strong enough to endure rough handling and exposure to the elements. Powder coated and anodized aluminum construction offers durability and reduces overall weight for added ease-of-use.
