Hi a very warm welcome to the site.
Ask your setting/workplace for a copy of their health and safety policy and then think about the things/procedures that happen on a daily basis that keep everyone safe and healthy eg. what happens at children's registration and collection times, hygiene - food, hands and cleaning up, storage arrangements and lifting, first aid areas and how the rooms inside and out are checked for risks, and then less regularly events such as Fire Drills and training dates.
It's possible your tutor has recommended this
level 3 handbook for your course?
Like pages 105+ of this
EYE book you will find pages in there to help you research, use the index to look for Health and Safety.
A few websites you can use to gather information from are
Public Health England
HSE.gov.uk
Food Standards Agency
OfStEd
Preventing unintentional injuries to Under 5s
you may also find your own local Authority website has advice that your setting uses
- find your council
Hope this helps a little xx
