If you have multiple liquefied natural gas (LPG) connections or one along with a piped natural gas (PNG) connection, be ready to have your cylinder blocked if you do not surrender it. The three government oil marketers blocked as many as 3.8 million LPG connections by March 2012.

Oil marketing companies IndianOil, Bharat Petroleum and Hindustan Petroleum together blocked nearly 2.9 million LPG connections belonging to customers having more than one connection across states. Similarly, around 900,000 LPG connections with consumers having PNG connections were blocked.
