PFD Monitor interpretation

Lack of warnings about dangerous currents in the waterfall pool

Wider context from the report

“(1) The two deceased men were unaware of the dangerous currents in the pool directly below the waterfall and the evidence indicated that other people were also unaware of the dangers. As the waterfall is in close proximity to the village of Llanberis and is easily accessible other people could die in identical circumstances and I am therefore of the opinion that a sign should be erected to warn people of the dangerous characteristics of the waterfall pool. ”

Is this part of a recurring concern?

Yes — Inadequate warnings about location-specific hazards at public waterside locations.

PFD Monitor interpretation

Severe weather temporarily prevents safely accessing the site to install safety warning signs.

Verbatim wording from the response

“Mae arwyddion wedi eu harchebu a’u derbyn a bwriedir eu gosod ar greigiau gerllaw pwll y rhaeadr er mwyn blaen-rhybuddio ymwelwyr i’r safle o’r perygl o farwolaeth sy’n bodoli oherwydd ceryntau tanddwr. Bydd yr arwyddion yn cael eu gosod cyn gynted â phosibl. Mae’r tywydd gwyllt diweddar wedi oedi’r gwaith gan fod angen sicrhau llwybr diogel i weithwyr gyrraedd y safle. Byddant yn cael eu gosod unwaith bydd tywydd yn caniatáu’r gwaith gael ei gynnal yn ddiogel a gobeithir y bydd wedi ei gwblhau erbyn diwedd mis Ionawr 2016.”
