Rhiwbach Buoyancy Aids

Users of Rhiwbach are asked to contribute towards a batch of buoyancy aids which are available for groups to use to cross the flooded chamber on floor one of the mine.

Buoyancy Aids (and Life Jackets) are used at the users own risk; instructional staff should satisfy themselves that the BAs are fit for purpose prior to each user. Any suspect BAs should be removed from the mine and the users group notified by either submitting the attached form, or emailing the users group: minereports@googlegroups.com
