More than 17,000 people have signed a petition calling for Chorley And South Ribble Hospital’s accident and emergency department to reopen.
The online petition, set up by Jane Astley, calls for more funding to be given to Lancashire Teaching Hospitals NHS Trust so it can be retained.
The A&E department shut on Monday, with bosses blaming acute staffing problems for the closure, which they say is temporary.
The Government must now respond to the petition as it has more than 10,000 signatures.
If it reaches 100,000 names, it will be considered for debate in Parliament.
Enid Armstrong, secretary/treasurer for the Friends Of Lancashire Teaching Hospitals NHS Trust, said she was not surprised so many people had signed the petition.
She said: “The hospital was built for the people of Chorley and they are very, very passionate about it.
“I know that from when we used to do car boot sales and market stalls and Christmas tombolas. Even if they don’t win they are not bothered because the money goes to the hospital.”
The Friends will discuss the situation at their annual general meeting at 7.30pm on Monday at Chorley Town Hall.
Chorley’s MP Lindsay Hoyle met Health Secretary Jeremy Hunt today and a full meeting with officials will be held early next week to talk about the hospital’s A&E department in detail.
It will also be discussed at a special meeting of Chorley Council at 5.30pm on Friday.
A notice of motion submitted by council leader Coun Alistair Bradley and deputy Coun Peter Wilson states “alarm” that it has closed.
It says: “Given the concerns about treatment and quality of care for Chorley residents, we ask that the A&E department at Chorley Hospital is re-opened as a matter of urgency.”
