Ní cheadóidh fostóir tumadóirí do thumadóirí, a bheidh ag gabháil d'oibríochtaí tumadóireachta, aer comhbhrúite ar mó a bhrú ná brú an uisce ag doimhneacht 50 méadar a úsáid.
An employer of divers shall not permit the use by divers engaged in diving operations of compressed air at a pressure which exceeds the pressure of water at a depth of 50 metres.
I gcás go n-úsáidfear aer comhbhrúite mar is cuí agus go mbeidh, ina chuid den ghléasra tumadóireachta nó den trealamh áirithe, píblíne aeir a seoltar aer isteach ann ó uachtar an uisce, beidh sé de dhualgas ar an bhfostóir tumadoirí a chinntiú go mbeidh caidéal aeir, gléas comhbhrúite .aeir nó sorcóir aeir mar chuid den ghléasra nó den trealamh sin, agus i gcás go mbainfear úsáid as gléas comhbhrúite aeir den chineál sin, go soláthrófar cúl-soláthar leordhóthanach aeir chun ligean don tumadóir an dromchla a bhaint amach má loiceann an gléas comhbhrúite.
Where compressed air is duly used and the diving plant or equipment concerned includes an air pipeline into which air is supplied from above water, it shall be the duty of the employer of divers to ensure that such plant or equipment includes an air pump or air compressor or air cylinder, and that where use is made of such an air compressor, a sufficient reserve of air is provided to allow the diver to reach the surface if the compressor fails.
