A defibrillator has been placed on Snowdon to help if anyone suffers a heart attack while they go walking
on the mountain.
The device has been installed at Hafod Eryri, which is capable of delivering an electrical shock that can jump-start a stopped heart if someone goes into cardiac arrest.
Such an item may be a lifesaver if anyone is in trouble near the top of the mountain, but other safety measures those venturing out can take may be of greater importance in saving lives on mountains all over Britain.
These include having the right men's outdoor clothing
or women's outdoor clothing
for the weather, particularly in the cold winter months, while items like a walking GPS
and Ordnance Survey maps
can help avoid navigational errors.
One famous person to die of a heart attack while climbing a mountain was politician Robin Cook, who collapsed on Ben Stack in the northern Highlands in 2005.
