The Irish Health Service Executive called for all approaches to medical facilities to be kept clear for users to access treatment.
Taoiseach (Irish prime minister) Micheál Martin said people who were not protesting “want this resolved”.
“We’re going to do everything we can to keep the economy going,” he added.
Earlier, Martin told RTÉ that the blocking of roads and infrastructure was “not a fair form of protest”.
He said it was “unacceptable” that people would be denied access to fuel and clear water.
“For people who said they were concerned about the price of fuel, to now be denying people access to fuel is beyond any logical comprehension.”
Martin said that the government did not anticipate violence.
However Irish Defence Minister Helen McEntee claimed the actions of some protesters was “now crossing into criminal behaviour”.
“There are genuine people there with genuine concerns…but those involved in protests who are actively blocking and preventing people from accessing fuel…they have to stop.”
Sinn Féin leader Mary Lou McDonald called for the taoiseach (Irish prime minister) and tánaiste (deputy PM) to “pick up the phone” to protesters.
McDonald also said she did not want to see “disruption” or protesters “sleeping in tractors” on O’Connell Street, adding “people should engage respectfully”.
