Practice Exam Questions And Correct

BSEE Wind Technician Safety Certification Practice Exam Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

1) What is the primary OSHA standard regulating fall protection in general industry?

• OSHA 1926 Subpart M
• OSHA 1910 Subpart D
• OSHA 1915 Subpart I
• OSHA 1904 Recordkeeping

Rationale: OSHA 1910 Subpart D addresses walking-working surfaces and

fall protection requirements for general industry, including wind energy.

2) Minimum free-fall distance permitted before a fall arrest system engages?

• 12 ft 1 / 4

• 6 ft
• 4 ft
• 20 ft

Rationale: ANSI/OSHA standards typically allow a maximum of 6 ft free fall

for personal fall arrest systems.

3) The purpose of a lockout/tagout (LOTO) procedure is to:

• Increase productivity
• Control hazardous energy during maintenance
• Mark faulty equipment
• Reduce paperwork

Rationale: LOTO isolates and controls energy sources to prevent accidental

startup or release.

4) Which PPE is mandatory when working near rotating equipment?

• Loose clothing
• Fitted clothing and tied-back hair
• Jewelry allowed
• Gloves with ribbons

Rationale: Rotation hazards require fitted clothing to avoid entanglement.

• / 4

5) Which standard outlines proper electrical safety practices?

A. ANSI Z359

B. NFPA 70E

C. ISO 45001

D. OSHA 300

Rationale: NFPA 70E provides electrical safety requirements including arc

flash protection.

6) What is the safest method to climb wind turbine ladders?

• Holding tools while climbing
• Using a fall arrest climbing system
• Running to save time
• Leaning back

Rationale: Fall arrest rail or cable climbing systems reduce fall risk.

7) Arc flash boundaries are determined primarily by:

• Turbine height
• Technician seniority
• Incident energy level
• Cable color

Rationale: Incident energy rating defines arc flash PPE and distance

requirements. 3 / 4

8) What is the first step in an emergency evacuation at height?

• Take photos
• Initiate communication and call for help
• Leave the victim
• Disable alarms

Rationale: Activate emergency response to ensure coordinated rescue.

9) A wind turbine nacelle is considered a confined workspace due to:

• Unlimited egress
• Limited ventilation and restricted entry/exit
• Open-air design
• Noise level alone

Rationale: Confinement increases hazard exposure like heat, fumes, limited

access.

10) When is a fire watch required during hot work?

• Optional
• When combustibles are nearby
• Only outdoors
• When supervisor is absent

Rationale: Fire watch reduces ignition risk around flammable material.
