The event is held annually from 9am on September 9 (the 9th hour of the 9th day of the 9th month).
SKDC Chairman Cllr Jacky Smith led a minute's silence to remember NHS and emergency services personnel who have died as a result of their service.
She said: "The men and women of our emergency services demonstrate incredible courage and professionalism every single day.
"Time and time again, they are there for us when we need them most. As a country, we are indebted to them for their extraordinary commitment to the public. This flag raising is our opportunity to honour the work they do and say a heartfelt thank you.
"This year it is especially important that we acknowledge and commemorate the Emergency Services and the NHS for the professionalism and care they have provided since the Covid-19 pandemic entered this country."
Emergency Services Day aims to:
- Promote good citizenship and the effectiveness and efficiency of the emergency services
- Encourage people to act responsibly to minimise the risk of having to use emergency services
- Educate people to learn life-saving skills and how to help the emergency services
- Encourage people to consider volunteering, possibly as a Special Constable or NHS Responder
More than two million people work and volunteer in the NHS and emergency services today, including 250,000 first responders.
They work in a range of jobs - from answering emergency calls to dealing with administration to practising medicine, fighting fires, policing the streets and saving lives at sea and on mountains, lowland and in caves.
