Natural gas customers in Galway city, Headford, Castlebar, Tuam Ballinrobe, Claremorris, Westport, Ballina and Crossmolina are being told to turn the supply at the meter box off until further notice.
Gas is an odourless substance until a smell is added so it is noticeable.
If a gas leak was now to occur, homeowners would not be able to smell it.
It was processed at the Ballanaboy terminal in Mayo however the odourless gas managed to enter the network, Shell EP confirmed.
In a statement issued by Gas Networks Ireland, the company confirmed a ‘quantity of odourless gas’ entered the network.
They said: “The operator of the Corrib gas terminal has confirmed that a quantity of odourless gas has entered the gas network. This affects natural gas customers in Galway and Mayo only.
“Natural Gas is odourless, but a smell is added, for safety purposes in the unlikely event of a leak.
“We are urging gas customers… to turn off their gas supply at the valve in their meter box until further notice.
“We are recommending this action because in the unlikely event of a leak customers in these locations only, will be unable to smell gas in the current circumstances.
“We will work with priority customers including hospitals to try to ensure their operations are not interrupted.
“We are working with the Corrib operator to resolve this issue and remove the un-odourised gas from the network in a safe and controlled fashion.”
The Environmental Protection Agency was notified that flaring at the site due to problems with the quality of gas exported from the terminal.
The EPA says it expected flaring to continue for a further 12 to 24 hours.
Efforts are also being made to remove the unscented gas from the network which could take up to 72 hours.
Inspectors from the EPA are currently monitoring the situation.

Shell had a close relationship with the Nazis during and after the reign of Sir Henri Deterding, an ardent Nazi, and the founder and decades long leader of the Royal Dutch Shell Group. His burial ceremony, which had all the trappings of a state funeral, was held at his private estate in Mecklenburg, Germany. The spectacle (photographs below) included a funeral procession led by a horse drawn funeral hearse with senior Nazis officials and senior Royal Dutch Shell directors in attendance, Nazi salutes at the graveside, swastika banners on display and wreaths and personal tributes from Adolf Hitler and Reichsmarschall, Hermann Goring. Deterding was an honored associate and supporter of Hitler and a personal friend of Goring.
Deterding was the guest of Hitler during a four day summit meeting at Berchtesgaden. Sir Henri and Hitler both had ambitions on Russian oil fields. Only an honored personal guest would be rewarded with a private four day meeting at Hitler’s mountain top retreat.
