1What is the primary purpose of GWO Basic Safety Training (BST)?
A.To certify wind turbine engineers
B.To provide foundational safety training for workers entering the wind energy industry covering working at heights, first aid, manual handling, fire awareness, and sea survival
C.To teach wind turbine design
D.To certify electrical technicians
Explanation: GWO Basic Safety Training (BST) is a modular safety training program developed by the Global Wind Organisation to establish a common safety standard for workers in the wind energy industry. The five modules — Working at Heights, First Aid, Manual Handling, Fire Awareness, and Sea Survival (for offshore) — ensure all personnel have baseline safety competencies before working on or around wind turbines.
2What is the correct procedure for donning a full-body safety harness for wind turbine work?
A.Put it on quickly without adjusting straps
B.Step into the leg straps, pull the harness over shoulders, connect the chest strap, and adjust all straps for a snug fit with the dorsal D-ring centered between the shoulder blades
C.Only clip the waist belt
D.Have someone else put it on for you without inspection
Explanation: Proper harness donning requires: (1) Hold the harness by the dorsal D-ring and shake to untangle straps, (2) Step into the leg straps, (3) Pull the harness up and over the shoulders, (4) Connect and adjust the chest strap at mid-chest level, (5) Tighten all straps for a snug but comfortable fit, (6) Verify the dorsal D-ring is centered between the shoulder blades. A properly fitted harness is critical — too loose allows excessive free fall distance, too tight restricts movement and circulation.
3What is the recovery position used for in first aid?
A.To treat broken bones
B.To maintain an open airway for an unconscious breathing casualty by placing them on their side to prevent choking on fluids
C.To stop severe bleeding
D.To treat burns
Explanation: The recovery position (lateral recumbent position) is used for unconscious casualties who are breathing normally. It keeps the airway open by allowing the tongue to fall forward and any fluids (vomit, blood) to drain from the mouth rather than blocking the airway. The casualty is placed on their side with the upper knee bent for stability and the head tilted slightly downward. The recovery position should NOT be used if a spinal injury is suspected unless the airway is at risk.
4What is the correct lifting technique for preventing back injuries during manual handling?
A.Bend at the waist and lift with your back muscles
B.Keep the load close to the body, bend at the knees and hips, maintain a neutral spine, and lift using leg muscles
C.Twist while lifting to gain momentum
D.Lift with arms extended away from the body
Explanation: Safe manual handling technique requires: plan the lift (assess weight, path, destination), stand close to the load with feet shoulder-width apart, bend at the knees and hips (not the waist), grip the load firmly, keep it close to your body (center of gravity), maintain a neutral spine (natural curve), lift smoothly using leg muscles, and avoid twisting during the lift. This technique minimizes stress on the lower back, which is the most common site of manual handling injuries.
5What are the four elements of the fire tetrahedron?
A.Water, earth, wind, fire
B.Fuel, oxygen, heat, and chemical chain reaction
C.Carbon, hydrogen, nitrogen, oxygen
D.Ignition, fuel, temperature, pressure
Explanation: The fire tetrahedron consists of four elements that must all be present for fire to exist: fuel (combustible material), oxygen (oxidizing agent, normally 21% in air), heat (sufficient temperature to ignite), and an uninhibited chemical chain reaction. Removing any one element extinguishes the fire. This model replaced the fire triangle (which had only three elements) to account for the chemical chain reaction component, which is how some extinguishing agents (dry chemical, halon) work.
6What is the purpose of a Personal Survival Technique (PST) or sea survival module in GWO BST?
A.To learn recreational swimming
B.To prepare offshore wind energy workers for emergency situations at sea including helicopter ditching, life raft boarding, and cold water survival
C.To obtain a fishing license
D.To learn boat navigation
Explanation: The sea survival module prepares workers for emergencies during offshore wind farm operations including helicopter ditching (underwater escape from a submerged helicopter), boarding and operating life rafts, cold water immersion survival, use of personal flotation devices, distress signaling, and helicopter rescue techniques (Hi-line, winching). This training is mandatory for workers who travel to offshore wind farms by helicopter or vessel and addresses the unique survival challenges of working at sea.
7What is the maximum free fall distance allowed when using a personal fall arrest system in wind turbine work?
A.3 feet (0.9 m)
B.6 feet (1.8 m)
C.10 feet (3 m)
D.20 feet (6 m)
Explanation: The maximum permissible free fall distance when using a personal fall arrest system (PFAS) is 6 feet (1.8 meters) per OSHA and most international standards. This is the maximum distance a worker can fall before the fall arrest system begins to engage. The total fall distance (free fall + deceleration + harness stretch + safety factor) must be calculated to ensure the worker does not contact a lower level. Self-retracting lifelines (SRLs) reduce free fall to less than 2 feet.
8What is the correct compression-to-ventilation ratio for adult CPR?
A.15:2
B.30:2
C.5:1
D.10:1
Explanation: The current recommended compression-to-ventilation ratio for adult CPR is 30:2 — 30 chest compressions followed by 2 rescue breaths, repeated until emergency services arrive or the casualty recovers. Compressions should be at least 2 inches (5 cm) deep at a rate of 100-120 per minute. High-quality, uninterrupted chest compressions are the most critical component of CPR. If untrained or unable to perform rescue breaths, continuous compression-only CPR is recommended.
9What does TILE stand for in manual handling risk assessment?
A.Time, Interval, Load, Equipment
B.Task, Individual, Load, Environment
C.Tool, Instruction, Lift, Exit
D.Training, Inspection, Logistics, Evaluation
Explanation: TILE is a manual handling risk assessment framework: Task (what activities are involved — pushing, pulling, lifting, carrying, twisting?), Individual (who is performing the task — their capability, fitness, training?), Load (what is being handled — weight, shape, grip, stability?), and Environment (where is the task performed — space, floor condition, temperature, lighting?). TILE helps identify risk factors and implement controls to reduce manual handling injuries. It should be applied before any significant manual handling activity.
10Which class of fire involves flammable liquids such as oil, diesel, or hydraulic fluid?
A.Class A
B.Class B
C.Class C
D.Class D
Explanation: Class B fires involve flammable liquids and gases including gasoline, oil, diesel fuel, hydraulic fluid, paints, and solvents. These are particularly relevant in wind turbines where hydraulic systems, lubricating oils, and transformer coolants are present. Class B fires should be fought with CO2, dry chemical, or foam extinguishers — NEVER with water, as it can spread the burning liquid. Class A covers ordinary combustibles, Class C covers electrical equipment, and Class D covers combustible metals.

Frequently Asked Questions

What is GWO Basic Safety Training?

GWO Basic Safety Training (BST) is a standardized safety training program developed by the Global Wind Organisation for workers in the wind energy industry. It consists of five modules: Working at Heights, First Aid, Manual Handling, Fire Awareness, and Sea Survival (offshore). BST is required for access to wind turbine sites operated by GWO member companies globally.

How long does GWO BST training take?

The full GWO BST program takes approximately 5 days to complete all five modules. Working at Heights requires 2 days, First Aid 2 days, Manual Handling 1 day, Fire Awareness half a day, and Sea Survival 1.5 days (offshore only). Some providers offer condensed schedules. Refresher courses are shorter, typically 2-3 days total.

How much does GWO BST cost?

GWO BST costs approximately $1,500-3,000 for the full five-module package, depending on the training provider, location, and whether the sea survival module is included. Individual modules can sometimes be taken separately. Refresher courses are typically 40-60% of the initial cost. Employers often cover the training costs.

How long is GWO BST certification valid?

GWO BST certificates are valid for 2 years from the date of completion. Before expiration, workers must complete refresher courses to maintain their certification. Expired certificates prevent access to GWO member wind turbine sites. Some employers require annual refreshers for certain modules.

Do I need the Sea Survival module for onshore wind?

The Sea Survival module is required only for offshore wind operations. Onshore wind technicians typically need only the four land-based modules: Working at Heights, First Aid, Manual Handling, and Fire Awareness. However, having all five modules provides maximum career flexibility across both onshore and offshore roles.

Where can I take GWO BST training?

GWO BST training is delivered by GWO-certified training providers worldwide. The GWO website (globalwindsafety.org) has a provider directory searchable by location and module. Training centers are located near major wind energy markets in Europe, North America, Asia, and other regions. All certified providers follow the same GWO standards.
