Fire Awareness in Wind Turbines: Preventing, Responding and Mitigating Fire Risks

Wind energy’s hidden hazard

Wind power is a cornerstone of the global energy transition, but towering turbines are not without risk. Fire incidents, though infrequent, can lead to catastrophic losses. Firetrace International reports that fire is the second leading cause of accidents in wind turbines, accounting for between 10–30 % of all catastrophic accidents. Data from the Caithness Windfarm Information Forum shows about 11.7 fires per year, yet 91 % of wind‑turbine fires go unreported. When a nacelle catches fire, operators often must stand by until it burns out; in 90 % of cases the turbine suffers significant damage or total loss. With each turbine costing millions to build and generating thousands of euros in revenue per day, avoiding fire disasters is critical.

Why GWO Fire Awareness training matters

To mitigate these risks, the Global Wind Organisation (GWO) developed a Fire Awareness module for workers in the wind industry. FMTC Safety’s GWO Fire Awareness course introduces delegates to the causes and dangers of fire in wind turbines and teaches them how to act correctly in an emergency. The half‑day course combines theoretical lessons and practical exercises, highlighting that panic cannot save lives; instead, knowledge and calm action do.

After classroom sessions on fire theory and turbine design, delegates practise recognising hazards, using extinguishing agents and executing contingency plans. Training covers the emergence of fire, proper use of fire extinguishers and blankets, smoke detection, emergency escape procedures and personal safety. It also demonstrates how to get yourself and colleagues to safety during realistic scenarios. Successful completion earns a GWO Module Fire Awareness certificate, valid for two years.

Common causes of wind turbine fires

Understanding why turbines catch fire helps technicians prevent incidents before they start. Recent analyses highlight three main causes:

• Mechanical failures: Gears and bearings inside the nacelle endure intense stress. Without proper lubrication and maintenance, friction generates heat that can ignite surrounding materials. Regular inspection and predictive maintenance programmes are essential.
• Electrical malfunctions: Generators, inverters and transformers handle high electrical loads. Short circuits, overloads or arcing can create sparks and heat that ignite combustible materials. Ensuring proper installation, tight connections and routine thermal imaging inspections reduces this risk.
• Lightning strikes: Because turbines stand tall on exposed sites, they are vulnerable to lightning. While turbines include lightning protection systems, these systems must be maintained to ensure they dissipate energy effectively; failure can lead to component damage and fire. Upgrading lightning conductors and surge protection devices helps reduce this threat.

The recent fire at the Clements Gap wind farm in South Australia illustrates the consequences. A turbine caught fire, igniting a grass fire below and causing about US$2.2 million in damage. Fortunately no one was injured, but the incident underscores the need for vigilance and robust prevention strategies.

What delegates learn in Fire Awareness training

Comprehensive training covers both theory and practice. According to survival training providers, the module teaches participants to:

• Demonstrate knowledge of fire development and spread, and understand the causes of fires in wind turbines.
• Recognise early signs of fire in a turbine environment.
• Understand contingency plans, smoke detection methods and emergency escape procedures.
• Take correct action on discovering a fire, including the safe use of portable fire extinguishers and fire blankets.
• Safely evacuate and account for personnel while maintaining communication.

Practical exercises use realistic equipment such as breathing apparatus, fire trays, hydrants and multiple types of extinguishers. Trainees practise extinguishing controlled fires and navigating smoke‑filled compartments, building muscle memory that is crucial during real emergencies.

Fire prevention strategies for wind turbines

Fire awareness training is only one piece of the safety puzzle. Operators and technicians can reduce fire risks by adopting proactive measures:

1. Implement rigorous maintenance routines. Scheduled inspections, lubrication and timely replacement of mechanical components reduce friction and overheating.
2. Monitor electrical systems. Regular thermographic surveys and testing detect hotspots or wiring faults that could spark a fire. Ensure proper grounding and surge protection.
3. Maintain lightning protection systems. Inspect conductors, downleads and grounding systems after storms. Upgrade older turbines with modern lightning protection to handle direct strikes.
4. Install automatic detection and suppression systems. Firetrace notes that cost‑effective suppression technology can detect and suppress fires at their source, reducing damage and downtime.
5. Establish clear contingency plans. Document evacuation routes, muster points and communication procedures. Use smoke detectors, heat sensors and remote monitoring to provide early warning.
6. Promote good housekeeping. Keep nacelle interiors clean, remove flammable debris and ensure that electrical enclosures are sealed.

Practical tips for technicians

During daily operations, technicians should:

• Wear appropriate personal protective equipment (PPE) and understand which fire extinguishers to use for different fire classes (e.g., CO₂, foam, powder).
• Verify that fire extinguishers, blankets and first‑aid kits are in place and inspected.
• Familiarise themselves with emergency ladders, descent devices and rescue kits used during evacuation.
• Participate actively in drills and report any malfunctioning equipment or safety concerns.
• Keep their GWO certificates up to date; refreshers are required every two years.

Building a fire‑conscious culture

Fire awareness goes beyond individual training—organisations must cultivate a culture where safety is everyone’s responsibility. Encourage open communication about hazards, schedule regular drills and integrate fire safety into daily toolbox talks. Supervisors should lead by example, ensuring that maintenance and housekeeping tasks are prioritised.

FMTC Safety’s GWO Fire Awareness course provides a solid foundation in fire prevention and emergency response. By understanding the causes of wind turbine fires, keeping equipment in top condition and practising coordinated responses, wind technicians can minimise risk and protect themselves, their colleagues and the multi‑million‑euro assets they maintain.
