March 22, 2018, The Department Of Energy released a circular that may affect the life of dormitory students. I said such because the item is commonly used by students staying in dormitories and boarding house. Perhaps it is also popular to low income households. It is more on safety over economy.
The small LPG tank. What they commonly call, regardless of brand, as gasulete. It gained popularity since the date I am not sure. It can be bought for a fraction of price of regular LPG. Small size. Easy buy and carry and back for refill. Required a very minimal space, perfect for dormitory and boarding house setting. Take it out only when needed and store after. Usually fitted with stove. It is lpg and stove in one. No need shed extra cash for a separate appliance.
This is it. Department Circular No. DC2018-03-0004 entitled: “Prohibiting the Sale and Distribution of Small-Sized 2.7kg Capacity and Below LPG Cylinders without the Required “For Outdoor Use Only” Marking in Addition to the Usual Mandatory Marking for LPG Cylinders.”
The lpg of concern lacks two safety features:
1.) Pressure Relief Valve (PRV); and
Pressure relief valves maintain specific amount of pressure within. If the limit exceeds the valve partially to fully opens releasing excess. It automatically shut off itself when adequate is attained. The feature is quite useful in case the tank is overfilled (imo) or subjected to heat. It will automatically balance itself and prevent exploding. Now, think what is gonna happen if this feature is absent.
Pressure regulator on the other hand maintains the lpg tank pressure vs the appliance to a consistent 2.75kPa. That is what I understand. Not so sure what happens if the pressure fluctuates. Leaks probably. Stove is directly installed on top of small lpg, so equipping it with appropriate pressure regulator is not an option.
According to Department of Energy absence of such make the item more likely to cause fires.
Small lpg are sold as the following.
1.) Shine Gaz;
2.) Petron Gasulette;
3.) Superkalan (Brenton); and
4.) Powerkalan (Pryce Gases)
I have seen many households and establishments having their lpg tanks on the outside. I assume there is a regulatory agency that require this. I am also considering the transfer of our regular lpg tank outdoor. This is the right thing to do. No matter how safe the lpg tank is made, accidents still happen. In case of failures, leaks can easily dissipates.
