The crew of a yacht were found to be suffering the early effects of carbon monoxide poisoning on arriving in St Helier Marina.
Jersey Fire and Rescue service was called out on Thursday evening (14 May) to reports of an onboard alarm sounding.
The crew of the sailing yacht which had travelled to the island were suffering with headaches.
It is one of the common symptoms of carbon monoxide poisoning - in addition to dizziness, an upset stomach and vomiting.
The odourless and potentially deadly gas can originate from engines, generators and fuel-burning stoves.
JFRS service is reminding mariners of the dangers of the 'silent killer'. Crew Commander Brown said:
"If travelling on your boat this summer, be aware of the causes of carbon monoxide, as this could be yourself in this situation.
- Cook in a well ventilated area.
- Ensure your cabin area is not affected by engine fumes.
- Ensure any electrical components, including batteries, are functioning correctly and not damaged when charging.“
