Working at Height on Wind Turbines

Wind turbine towers reach heights of 80 to 150 metres, making work at height the primary safety hazard.
Access to nacelles and hubs is via internal ladders, climbing systems, or service lifts within the tower.
Fall arrest systems, harnesses, and self-retracting lifelines are mandatory for all climbing and nacelle access.
Rescue from a wind turbine nacelle at height is extremely challenging and must be pre-planned.
Weather conditions at hub height are significantly more severe than at ground level, especially wind and cold.
The Work at Height Regulations 2005 apply to all work on wind turbines during construction and maintenance.
GWO (Global Wind Organisation) Basic Safety Training is the industry standard for turbine workers.
Confined space hazards exist inside the tower base, nacelle enclosure, and blade root areas.
Dropped objects from turbine height can be lethal — exclusion zones must be maintained at ground level.
Lightning strike risk on tall turbine structures requires monitoring and a clear stop-work procedure.

Prevent fatal falls	Falls from turbine towers and nacelles at heights exceeding 80 metres are invariably fatal without fall arrest systems.
Rescue challenges	Incapacitated workers at nacelle height cannot be rescued quickly without a trained team and pre-planned procedure.
Extreme conditions	High wind speed, cold, and lightning at hub height create life-threatening conditions that change rapidly.

Do

Don't

Complete GWO Basic Safety Training before accessing any wind turbine structure
Wear a full body harness and connect to the fall arrest system before climbing
Check weather forecasts for wind speed and lightning risk before ascending the tower
Carry out a pre-climb equipment check on harness, lanyards, and self-retracting lifelines
Brief the team on the rescue plan and confirm rescue equipment is available at height
Maintain an exclusion zone at ground level to protect against dropped objects from above
Use the service lift where available to reduce climbing fatigue and fall exposure time
Carry a charged radio or phone for continuous communication with the ground team
Monitor weather conditions while at height and descend if conditions deteriorate
Report any defects in fall arrest systems or tower access equipment immediately

DON'T climb a wind turbine without valid GWO training and a pre-climb health check
DON'T ascend the tower without connecting to the fall arrest system at all times
DON'T work at nacelle height when wind speeds exceed the safe working limit specified
DON'T remain at height during lightning storms — descend immediately when warnings are issued
DON'T carry loose tools or materials that could be dropped from height during climbing
DON'T enter the nacelle or blade root without checking for confined space hazards first
DON'T work alone at turbine height — a minimum of two persons is required for rescue
DON'T use damaged harnesses, lanyards, or self-retracting lifelines — replace immediately
DON'T climb without adequate rest — fatigue increases the risk of errors at height
DON'T allow ground workers within the exclusion zone while people are working above
