Hi pinkcandy,
You should find a lot of what you need with these and in your setting's policies and procedures:
http://www.elderabuse.org.uk/http://www.adass.org.uk/old/publications/guidance/safeguarding.pdfAlso see you local Safeguarding Adults Board website.
Roles - Social services, police, health, voluntary and private agencies - research their roles.
Advice - your own management and policies and procedures, local safeguarding board, guidelines such as the essential standards and the social care worker's codes of practice.........
Hope that helps
Aunty Sue
