A rescue procedure is an essential part of every work at height operation. Even the most advanced fall protection equipment cannot eliminate all risks, and stopping a fall is only the first stage of an emergency response. Once a worker has been suspended in a harness or becomes trapped in an elevated or confined location, rapid and organised rescue is necessary to reduce the risk of further injury and allow medical treatment to begin as quickly as possible. A properly developed rescue procedure ensures that recovery can be carried out safely without exposing additional workers to unnecessary danger.
The Work at Height Regulations 2005 require work at height to be properly planned, including arrangements for emergencies and rescue. This means employers should consider how casualties will be recovered before work starts rather than relying solely on the emergency services after an incident occurs. Every rescue procedure should be specific to the workplace, supported by suitable equipment and understood by the personnel responsible for carrying it out.
Why Every Work at Height Activity Needs a Rescue Procedure
A successful fall arrest does not mean the emergency has ended. Although the worker may avoid striking the ground, they can remain suspended several metres above the surface with no practical means of reaching safety. If the casualty has suffered injuries during the fall or becomes unconscious, self rescue may be impossible.
Remaining suspended for an extended period also creates additional medical concerns. Suspension in a harness can affect blood circulation, particularly when the casualty remains motionless. Industry guidance therefore recommends recovering suspended workers as quickly as reasonably practicable rather than waiting for external assistance where an effective on site rescue capability is available.
Many work locations present additional challenges that make immediate planning essential. Workers operating on telecommunications towers, wind turbines, industrial chimneys, offshore platforms or confined spaces may be inaccessible using conventional emergency response methods. In some cases, public emergency services require significant time to reach the casualty, particularly at remote industrial sites.
A documented rescue procedure ensures that everyone understands their responsibilities before an emergency develops. Instead of making decisions under pressure, rescue personnel can follow predefined methods that have already been assessed for safety and practicality.
What Should Be Included in a Rescue Procedure
A rescue procedure should be tailored to the specific workplace rather than copied from a generic template. Different structures, access methods and work activities create different rescue challenges, so the procedure should reflect the hazards identified during the risk assessment.
The document should clearly describe how the casualty will be reached, secured, recovered and transferred to medical care. It should also identify the equipment required, the personnel responsible for the rescue and the communication methods that will be used throughout the operation.
An effective rescue procedure normally includes:
- The types of emergency that may occur.
- Roles and responsibilities of rescue personnel.
- Rescue methods for each working location.
- Required rescue equipment and anchor points.
- Communication and emergency contact arrangements.
- Procedures for casualty care after recovery.
The procedure should also identify situations where different rescue techniques may be required. For example, recovering a worker suspended beneath a roof edge requires different equipment and methods from rescuing a casualty inside a confined space or on a wind turbine.
Weather conditions, nearby machinery, electrical hazards and restricted access routes should all be considered because they may influence how the rescue is performed safely.
Equipment Used During Rescue Operations
Rescue procedures rely on equipment specifically designed for casualty recovery rather than ordinary fall arrest equipment alone. Although harnesses and lanyards provide protection during normal work, additional devices are usually required to raise, lower or retrieve a casualty safely.
Controlled descent devices certified to EN 341 are commonly used to lower casualties from elevated structures in a controlled manner. Rescue kits combining lifting and lowering functions allow rescuers to recover suspended workers while maintaining continuous fall protection throughout the operation.
Tripods, davit arms and retrieval winches are widely used during confined space work. These systems enable casualties to be lifted vertically without requiring additional rescuers to enter hazardous environments unnecessarily. In industrial rope access operations, specialised hauling systems, descenders and rescue pulleys provide similar recovery capabilities.
Typical rescue equipment includes:
- Controlled descent devices.
- Rescue kits with raising and lowering capability.
- Tripods, davit systems and retrieval winches.
- Rescue stretchers where casualty movement is required.
- Certified connectors, pulleys and anchor slings.
- Communication equipment and first aid supplies.
All rescue equipment should be compatible with the site’s fall protection system and inspected in accordance with EN 365 and the manufacturer’s maintenance instructions. Equipment stored for emergency use should remain immediately accessible and ready for deployment at all times.
Training, Competence and Rescue Drills
Even the most comprehensive rescue procedure cannot provide effective protection unless personnel are trained to implement it correctly. Rescue operations often take place under stressful conditions where rapid decision making and effective teamwork are essential. Practical competence therefore plays a far greater role than written documentation alone.
Workers responsible for rescue should receive training that reflects the actual equipment and environments found on site. This normally includes casualty assessment, anchor selection, operation of rescue devices, communication procedures and methods for preventing additional falls during the recovery process.
Rescue drills are equally important. Regular practical exercises allow teams to verify that equipment functions correctly, communication systems remain effective and rescue procedures can be completed within realistic timescales. Many organisations conduct rescue exercises at least annually, while higher risk industries such as offshore energy, rope access and wind energy often carry out drills several times each year.
Training should also address changing workplace conditions. Construction projects, for example, evolve continuously as structures are completed, meaning rescue routes and anchor locations may require frequent revision. Rescue procedures should therefore be reviewed whenever significant changes occur to the workplace or working methods.
Competence should not be viewed as a one time achievement. Regular refresher training helps maintain practical skills and ensures rescue teams remain familiar with new equipment, revised procedures and updated safety guidance.
Common Mistakes and Best Practice
One of the most common mistakes is assuming that emergency services alone will provide an adequate rescue capability. Although fire and rescue services play a vital role, they may require considerable time to reach casualties suspended from structures or located within remote industrial sites. Employers should therefore provide appropriate on site rescue arrangements whenever reasonably practicable.
Another frequent problem is preparing a rescue procedure that does not match the actual workplace. Generic documents often fail to consider site specific hazards such as restricted access, overhead obstructions, electrical installations or structural changes. Rescue planning should always reflect the real conditions in which work will take place.
Insufficient equipment is another recurring issue. Rescue kits stored in locked vehicles or distant welfare facilities may delay recovery when every minute is important. Rescue equipment should be positioned close to the work area and inspected regularly to ensure it remains immediately available.
Poor communication can also compromise rescue operations. Rescue personnel should know who has authority to initiate the rescue, how emergency information will be shared and how external emergency services will be contacted if additional assistance becomes necessary.
Best practice begins with thorough planning. Rescue procedures should be developed alongside the work at height risk assessment, integrated into the overall safe system of work and supported by appropriate equipment, competent personnel and regular practical exercises. The procedure should also be reviewed after every drill, near miss or actual rescue to identify opportunities for continuous improvement.
A rescue procedure is far more than a written emergency document. It is a structured operational plan that combines risk assessment, trained personnel, certified rescue equipment and clearly defined responsibilities to ensure that workers can be recovered quickly and safely when an incident occurs. By developing site specific rescue procedures and practising them regularly, organisations can significantly improve emergency response while reducing the consequences of accidents during work at height.
