INSTRUCTIONS AND SUGGESTIONS FOR THE GUIDANCE OF USERS OF AERATING CYLINDERS
11. (1) The following instructions and suggestions are issued with a view of minimising the risk attendant on the use of aerating cylinders, including those charged direct from tubes of liquefied gas; also as a guide to those in charge to point out to them the need there is for constant care and watchfulness on their part while in performance of theirduties:-
"THE INSPECTION OF MACHINERY ACT OF 1951"
CHARGING
Before putting the cylinder under pressure see that the pressure reducing valve is correctly set. Examine all mountings, pressure gauge, valve, and fitting plugs, etc., and see that they are in good order and
screwed up.
The method of charging will vary according to the opinion of various makers, and to secure the greatest efficiency their instructions should be carefully observed.
Where cylinders arc charged direct from tubes of liquefied gas, it is essential that the attendant should remember that he is dealing with a gas at a very high pressure, as most tubes are charged to from 800 to 900 lb. per square inch, which pressure is considerably in excess of the bursting pressure of the aerating cylinder.
In order safely to control the use of the gas at such pressure, a pressure reducing valve is fitted to the stop valve on the gas tube, and, when properly regulated, automatically checks the flow of gas except below a given pressure.
72 Reg. 11 REGULATIONS
In the event of the reducing valve being set at too high a pressure or of it creeping due to leaking valve seat or being partly frozen, the safety valve releases the surplus pressure, thus showing that constant care of both reducing and safety valves is essential to safe working.
The stop valve on the gas tube must at all times be opened slowly.
The small stop cock at the delivery side of the reducing valve requires to be first closed; the stop valve is then opened carefully, avoiding any sudden rush of gas, particular notice being taken that the setting of the reducing valve is correct; leaving the stop valve still open, the small stop cock is then opened slowly, allowing the gas to enter the cylinder until the required working pressure is reached.
Where gas is first let into the cylinder and the water forced in later by means of an hydraulic pump, care should be taken that the gas pressure does not exceed 60 to 70 lb. per square inch, otherwise the safe working pressure will be reached before the required amount of water has been pumped in.
All valves between gas tube and cylinder must be closed over night.
WATER
Water used in aerating cylinders should be pure water, having been previously passed through an approved filter. Artesian and well water generally have a detrimental effect on the lining of the cylinder.
PRESSURE GAUGE
Particular care requires to be taken of the pressure gauge. See that it at all times works freely and registers correctly; otherwise the cylinder may be carrying a pressure much different from that which is shown on the dial. See that the pressure gauge is not subjected to violent shocks through sudden inrushes of gas, also that any inaccuracy in the gauge is immediately corrected.
PRESSURE REDUCING VALVE
The pressure reducing valve plays an important part in the safety of the cylinder, requires careful attention, and, when once set to the working pressure, should not be altered without good reason. It receives the gas from the gas tube at an exceedingly high pressure, and delivers it to the cylinder at safe working pressure.
In setting a reducing valve, disconnect pipe to cylinder; slack back adjusting screw till there is no compression on spring; open small stop cock on reducing valve and open slowly the stop valve on gas tube. As now set no gas should pass through; then close small stop cock and gradually screw up adjusting screw till the hand on pressure gauge points to the working pressure~for example, 100 lb.-and let stand for a few minutes. As now set the pressure should remain at 100 lb. Should the pressure continue to increase, it is evident that there is a leakage, necessitating repairs to the reducing valve. Such tests should be carried out from time to time for creeping, and the accuracy of the gauge tested by comparing with the blow-off of the safety valve.
SAFETY VALVE
The safety valve is fitted to a cylinder or charging set so as auto- matically to relieve any surplus pressure over and above the safe working pressure. It requires careful attention, and should be tried at the
REGULA nONS Reg. 11 73
commencement of charging operations to see that the valve is not stuck in its seat. Neglect of the safety valve may have serious results; the majority of accidents to gas cylinders are due to the valve being stuck in its seat.
In some cases an accident has been caused by the attendant interfering with the setting of the safety valve; and in addition to the risk to life and property such interference renders the person responsible liable to a heavy penalty.
A safety valve can only be such when kept in good working order, therefore such safety valves require to be corrected by an Officer of this Department at least once in every year.
FREEZING
It is not uncommon, particularly in winter time, for a stop valve or a pressure reducing valve to become frozen, whether open or closed. If water is allowed to leak back through the check valve into the small passages of the reducing valve, freezing will often take place as soon as the gas is turned off.
Either by way of prevention or cure, the best means to employ is a bag wrung out of hot water and laid over stop valve and reducing valve for a few minutes.
During thawing operations the gas inlet valve on the cylinder should be closed, as it sometimes happens that a stop valve may be opened up several turns before the pressure of the gas overcomes the obstruction, the resulting rush of gas having the effect of a violent blow rather than a steady pressure.
CLEANING
All internal surfaces of gas cylinders, pipes, and connections must be kept thoroughly tinned. The whole should be periodically washed through with hot water and soda.
When a plant has been standing out of use for a period, those portions of a plant with which syrup and fruit juices come in contact should be washed through with hot water and bisulphate of lime, the operation being completed by thorough rinsing with filtered water.
Pitting of the tinned surfaces should be looked for during cleaning operations, and its presence immediately reported to the Inspector.
CARE OF THE PLANT
Malee yourself thoroughly conversant with the method of operating and the use of all mountings on the particular class of cylinder under your care.
See that mountings are at all times in perfect working order and free from leakages.
When bottling operations are carried on, see that the face masks, gauntlets, and breast protections are constantly worn.
Take pride in the plant under your charge, remembering that you are handling gas at a very high pressure, and anything but strict attention to duty may cause destruction to life and property.
INSTRUCTIONS TO INSPECTORS
(2) In testing aerated water vessels under hydrostatic pressure the test pressure shall not exceed 10 per cent. above working pressure.
74 Reg. 12 REGULATIONS
In testing such vessels made of mild steel and fitted with block tin bag lining, the lock nut on the nipple of the tin bag is to be slacked back slightly during the test. If during the test there is any sign of leakage between the nipple and the top plate this is a sure sign that the tin bag is leaking; under such circumstances the use of the vessel must be prohibited until the tin bag has been renewed.
(3) All aerated water vessels shall be opened up at least every five years for the examination of the internal tinned surface.
If the tinned surface is pitted or defective the vessel must be retinned or if lined its lining renewed.
At the time of such inspection all defective or fatigued bolts and/or studs must be renewed.
( 4) All pressure gauges and pressure reducing valves shall be checked with the standard pressure gauge every twelve months or more often if considered necessary.
