    Carbon monoxide poisoning.

Carbon monoxide (CO) poisoning in helicopters happens when exhaust fumes containing CO leak into the cabin. This can be due to exhaust system leaks or ventilation issues. CO is a colorless, odorless gas that can cause headache, dizziness, nausea, confusion, and even death by preventing oxygen from reaching the body’s organs.

Preventive Measures:

  • Regular maintenance of the exhaust and ventilation systems.
  • Installation of CO detectors in the cabin.
  • Proper pre-flight checks for potential leaks.

Emergency Response:

  • Increase ventilation immediately if CO poisoning is suspected.
  • Use supplemental oxygen if available.
  • Land as soon as possible and seek medical attention.
