They shall not affect the performance of the safe break. 5.1.6 Safe breaks type 1 and type 2, except nozzle breaks, when operated shall close liquid lines both up stream and down stream of the break. For safe breaks type 2 it is not required to close vapour lines either side of the break. A means to close off vapour lines may be included. 5.1.7 On re-usable safe breaks, the sections that break away shall be constructed so that the means of reconnection cannot be damaged by impacts suffered as a result of separation. 5.1.8 The construction shall be such that on reconnection of a re-usable device, or attempted reconnection of a non re-usable device, fluid shall not be sprayed out during the reconnection action. 5.2 Hose breaks Hose breaks which incorporate hose shall use hose conforming to EN 1360 or prEN 13483. 5.3 Inlet threads 5.3.1 Safe break type 1 Form 1 threads for the hose connection shall be parallel threads according to EN ISO 228–1 according to Table 1.
