Useful information about self-rescue and evacuation devices

What are self-rescue and evacuation devices, and when are they used?

Self-rescue and evacuation devices enable a person to leave a hazardous workplace independently and in a controlled manner using a rope. They are used when the regular escape route can no longer be reached safely or when rapid evacuation from height is required. Typical situations include fires, technical faults, blocked access routes or other emergencies on mobile platforms, masts and towers.

Unlike complex rescue systems for assisted casualty rescue, personal evacuation devices are designed for rapid deployment and the simplest possible operation. SKYLOTEC self-rescue devices can be carried directly at the workplace or kept close at hand so that no valuable time is lost in an emergency.

How do self-rescue devices differ from conventional rescue devices?

During self-rescue, the user leaves the hazardous area independently using a designated evacuation device. Conventional rescue devices, by contrast, are often operated by a second trained person and may also provide functions for lifting, relieving or lowering an injured person in a controlled manner.

Self-rescue and evacuation devices are therefore particularly useful when employees must be able to leave a workplace in an emergency without external assistance. However, they do not replace a complete rescue concept. If a person is injured, incapacitated or no longer able to use the device independently, supplementary procedures for assisted rescue must be provided.

What advantages do fully automatic self-evacuation devices offer?

Fully automatic self-evacuation devices regulate the descent process independently and do not require continuous manual control during the downward movement. This can reduce operating errors and simplify evacuation procedures in an emergency. This is particularly relevant when users are acting under stress, with limited visibility or in an unfamiliar hazardous situation.

Compared with manual descenders, the decisive advantage lies in their intuitive operation: the system is specifically designed for personal emergency evacuation and automatically controls the downward movement. Compact dimensions and a low transport volume also make it easier to carry the self-rescue device directly at mobile workplaces or within personal reach.

Which applications are personal evacuation devices suitable for?

Personal evacuation devices are particularly suitable for exposed workplaces where an alternative downward escape route may be required in an emergency. These include mobile platforms, work platforms, masts, towers and other elevated work areas with restricted access or escape options.

It is essential that the required rope length, a suitable anchor point and a clear evacuation route are determined before work begins. The device must be positioned so that it remains quickly accessible even under emergency conditions. Self-rescue must therefore not be improvised, but must form part of the risk assessment and the company’s emergency planning.

What advantages does the SKYLOTEC DEUS ONE offer for self-rescue?

The SKYLOTEC DEUS ONE is a compact, fully automatic self-evacuation device for personal emergency evacuation. Its convenient design allows it to be carried directly on the body or in a compact rope bag, making it immediately available at the workplace.

The automatic descent process requires no additional intervention in the downward movement during evacuation. The DEUS ONE is designed for one person and is combined with a particularly compact hybrid rope. Depending on the version, the system is available with a rope bag or in moisture-protected packaging, allowing it to be adapted to different storage and application requirements.

What must be considered regarding rope length, user weight and evacuation height?

The self-rescue device must be suitable for the actual evacuation height and the user’s weight. The available rope length must be sufficient to reach a safe destination area. At the same time, the load limits approved for the respective device must not be exceeded.

Potential obstacles, edges, façade projections, wind conditions and pendulum movements must also be taken into account during planning. An insufficient rope length, an unsuitable anchor point or a blocked descent route can prevent evacuation. The entire escape route must therefore be assessed in advance and checked regularly for changes.

Which standards apply to self-rescue and evacuation devices?

EN 341 is particularly relevant for personal evacuation devices. It defines requirements for descender devices used for rescue and evacuation. Depending on the product and target market, additional international requirements such as ANSI Z359.4 may also apply.

However, the stated standard alone is not decisive. The device must be explicitly approved for the intended application, the specified user weight and the required descent height. The manufacturer’s instructions regarding storage, inspection, service life and operating limits must also be observed.

How is a self-rescue device integrated into an evacuation concept?

A self-rescue device must be incorporated into the risk assessment and the company’s evacuation concept before work begins. Suitable anchor points, escape routes, descent heights, user groups and possible restrictions must be defined. It must also be established in which situations self-rescue is possible and when assisted rescue is required.

Users must be familiar with the specific SKYLOTEC evacuation device and know the intended procedures. Regular instruction and practical exercises ensure that the device can be used quickly and correctly in an emergency. Only the combination of a suitable self-rescue device, an accessible anchor point and a practised evacuation procedure creates a reliable emergency concept.
