Climbing high into the air is a normal part of a wind technician's day. Modern turbines stand between 80 to 140 meters high. At these heights, there is no room for mistakes.

Staying safe is not just about wearing the right gear—it starts with having the right safety mindset.

1. Respect the Height, Do Not Fear It

Experienced technicians will tell you: “Respect the height, do not fear it.” Fear makes you nervous, makes your hands sweat, and causes rushed decisions. Respect means you move deliberately, you never skip safety steps, and you think about risks before you start moving.

2. The Golden Rules of Height Safety

🦺 Your Harness is Your Life

Before every single climb, you must complete a non-negotiable inspection of your harness and fall-arrest block.

  • Look for cuts or fraying in the straps.

  • Check for damaged stitching.

  • Inspect metal buckles for cracks or rust.

  • The Rule: If a harness looks suspicious, do not use it. Get a replacement instantly.

🔗 The "Never Unclip" Principle (Two-Point Rule)

When climbing or moving inside the nacelle, you must always be attached to a certified anchor point. When you move from one anchor to another, use your double lanyards to ensure you are never completely unattached from the turbine structure.

This sounds simple, but when you are physically tired or under time pressure, this is exactly where accidents happen.

🪢 Know the Rescue Plan Before You Climb

Before you go up the tower, you and your partner must know the site-specific rescue plan.

  • If your colleague faints or gets hurt inside the hub, how do you get them down?

  • Where is the rescue kit (like a Milan or ActSafe device) located?

  • Who calls the emergency services?

  • The Rule: If nobody has explained the rescue plan on a new site, do not climb. Ask the Site Manager first. Being safe is being professional.

3. Tool Management: Dropping Objects is Lethal

If you drop a heavy 19mm wrench from 100 meters in the air, it hits the ground with the force of a bullet. It will easily go through a safety helmet and kill someone below.

  • Tether Everything: Every tool you take up the tower—wrenches, multimeters, radios, and even your phone—must be attached to your harness or a tool bag using safety tethers or lanyards.

  • Drop Zones: Ensure the area directly under the turbine is blocked off with warning tape while you are working above.

4. Manage Your Fatigue

Climbing towers is physically exhausting. When your body is tired, your balance, coordination, and focus drop rapidly.

If you feel completely exhausted or dizzy, speak up and tell your team leader. A good safety culture means it is always safe to say stop when you cannot work safely.
