Soon, the kitchen at Parliament House will run entirely on CNG with a joint parliamentary committee approving a proposal for a piped connection to the premises.
The committee on Maintenance of Heritage Character and Development of Parliament House Complex, headed by Lok Sabha Speaker Sumitra Mahajan, approved the proposal Monday.
Officials said the pipe will be covered with stone slabs that match the exterior of the building.
The kitchen was shifted out of the main building in 2012 in the aftermath of the Mumbai Mantralaya fire, following orders from the then Speaker Meira Kumar.
The Delhi Fire Department had also raised an alarm over the storage and use of LPG cylinders in the main heritage building, commissioned in 1927.
The multiple kitchens in the entire premises cater to nearly 4,000 people, including MPs, staff, media and security personnel during the session.
Sources said the idea had been sent to the Indian National Trust for Art and Cultural Heritage (INTACH) for consideration and endorsement.
The multi-party committee includes Minister for Heavy Industries and Public Enterprises Anant Geete (Shiv Sena), Congress leader in the Lok Sabha Mallikarjun Kharge, Deputy Speaker M Thambidurai, L K Advani (BJP), Trinamool Congress leader Sudip Bandyopadhyay, Biju Janata Dal leader Bhartruhari Mahtab, Janata Dal(United) president Sharad Yadav, K Rahman Khan (Congress) and CP Thakur (BJP). Home Minister Rajnath Singh, Parliamentary Affairs Minister M Venkaiah Naidu and Rajya Sabha Deputy Chairman P J Kurien are ex-officio members of the committee.
CNG consists mostly of methane and is drawn from gas wells or in conjunction with crude oil production.It also contains hydrocarbons as well as other gases such as nitrogen, helium, carbon dioxide, sulphur compounds and water vapour.
A sulphur-based odourant is normally added to CNG to facilitate leak detection. It is lighter than air and normally dissipates in the case of a leak, giving it a significant safety advantage over gasoline or LPG.
