1. HENDERSON EXPLAINED NON-INERT GAS CONTAINERS IT

+

13

THAT IF CONTROL WERE TO BE EXTENDED TC OULD AT CHCE AFFECT NUMEROUS REFRIGERATED INSTALLATIONS SUCH AS AIR CONDITIONING PLANTS IN LARGE COMMERCIAL AND PUBLIC BUILDINGS, COLD STORAGES AND ICE PLANTS WHICH WOULD ENORMOUSLY INCREASE THE SCOPE OF ENFORCEMENT CF THE CRDINANCE.

HE SAID IT WAS ALSO DOUBTFUL IF SIMILAR RIGID CONTROL ON REFRIGERATED SYSTEMS WAS EXERCISED ANYWHERE ELSE OR WAS INDEED LECESSARY.

+A MUCH MORE DETAILED STUDY WOULD BE NEEDED TO ESTABLISH CRITERIA FOR VESSELS CONTAINING NON-INERT GASES WHICH ARE CONNECTED TO AIR OR GAS COMPRESSING PLANT CONTROL,+ MR. HENDERSON SAID.

+THEREFORE SINCE WE CANNOT PROCEED WITH THE NON-INERT GASES AT PRESENT I HAVE DECIDED FOR THE TIME BEING TO DELETE THE REFERENCE TO MY PROPOSAL TO EXTEND THE APPLICATION OF THE ORDINANCE TO VESSELS CONTAINING COMPRESSED INERT GAS.+

UNDER THE NEW LAW THE AMENDMENTS TO THE PRINCIPAL ORDINANCE INCLUDE CLARIFICATION OF THE POWERS OF INSPECTORS OF LAND BOILERS- THE APPLICATION OF THE ORDINANCE TO BOILERS AND PRESSURE RECEIVERS WHICH HAD PREVIOUSLY BEEN EXEMPTED WHERE OWNERSHIP CHANGED FROM THE CROWN CLARIFICATION OF THE SCOPE OF EXEMPTION ACCORDED TO ANY PRESSURE EQUIPMENT FIXED ON A FLOATING CRAFT OR INTENDED FOR SUPPLY OF LOCOMOTIVE POWER TO A VEHICLE, WHICH ARE COVERED BY OTHER LEGISLATION AND A BROADENING OF THE POWER TO HOLD INQUIRIES INTO ALL ACCIDENTS IN OR TO BOILERS AND PRESSURE RECEIVERS.

THE NEW LAW ALSO REQUIRES THAT TECHNICAL DOCUMENTS SUEMITTED TO THE REGISTRAR OF BOILERS AND PRESSURE RECEIVERS, IF WRITTEN IN A LANGUAGE OTHER THAN ENGLISH OR CHINESE, SHOULD BE ACCOMPANIED BY AN ENGLISH TRANSLATION AND THAT ALL APPLICATIONS FOR REGISTRATION OF EQUIPMENT MUST BE MADE AT LEAST 30 DAYS BEFORE THE EQUIPMENT IS PUT

INTO USE.

IT ALSO MAKES PRESSURE ACCUMULATION TESTS OBLIGATORY IN THE CASE OF EXAMINATION OF NEW EQUIPMENT SPECIFIES THE PROCEDURE FOR CARRYING OUT PRESSURE ACCUMULATION TESTS ON BOILERS AND MORE REALISTIC TEST PRESSURES FOR HYDRAULIC TESTS OF EQUIPMENT- AND MAKES IT CLEAR THAT A PORTAELE GAS GENERATOR MAY REQUIRE EXAMINATION BEFORE PERMISSION IS GIVEN FOR IT TO BE USED.

MEASUREMENTS IN THE NEW LAW ARE TO BE GIVEN IN IMPERIAL AS WELL AS METRIC UNITS BECAUSE VERY OFTEN BOILERS AND PRESSURE VESSELS HAVE BEEN IMPORTED WITH SPECIFICATIONS AND INSTRUMENTATIONS IN IMPERIAL UNITS, WHICH MAKES IT DIFFICULT TO GO FULLY METRIC IN THIS FIELD AT PRESENT.
