Sizes of Containers
- 68 kg (150 lb) – 907 kg (2000 lb)
Fusible Plugs
- 1 at valve – 3 at end of container
- melting temperature – approximately 150°F
- purpose
- never remove or tamper
Properties of Chlorine
- gas – 2 ½ times heavier than air
- 1 volume of liquid chlorine chlorine = 45 volumes of chlorine gas
- Chlorine has a high coefficient of expansion, i.e. temperature rise of 25°C will increase volume by approximately 85%.
- Cylinders are filled no more than 85% of volume.
- Chlorine by itself is non-flammable and non-explosive.
- It will support combustion at high temperatures.
Valves
- have packing with adjustable nuts
- gasket – lead or fibre at interface of all connections
replace with new when connecting
Safety Equipment
- SCBA – Self Contained Breathing Apparatus
- storage location
- exhaust fans – intake locations
- scrubbers
- First Aid – remover from contaminated area
obtain appropriate first aid
see a physician
MSDS - eyes – flush with water
see a physician - have an emergency plan
- make Fire Department familiar with your storage facilities
- gas detection with alarms
Vacuum Chlorinator
At point A, water passes through the injector under pressure. This forms a vacuum and causes the diaphragm B to be pulled away from the seat. This allows the vacuum to be transmitted to the rate valve C. If the rate valve is open, vacuum is transmitted through the rate indicator D to the regulating assembly E. The regulating diaphragm is pulled toward the chlorine inlet valve F, opening it. This allows chlorine gas to enter the system, to pass through to A where it is mixed with water and discharged to the point of application. If there is a vacuum failure, a spring on the inlet valve will move the diaphragm away from the valve, close the valve and stop the flow of chlorine. If the valve sticks in the open position, chlorine would pass through the centre of the diaphragm and out through the vent connection to the atmosphere.
