Hi, did the criteria before this one ask you to identify health, safety and security hazards in general and in your setting?
Consider next how you'd react to them if encountered.
eg. a health and safety risk would be spilled water on the floor maybe near handwashing facilities, a play-tray or craft table. To mitigate the hazard and make sure slips & falls were avoided what would you do?
The same for security, what risks have you already identified eg. children leaving the setting unseen, visitors to the setting entering without permission or checks?
There's good reading & images in the
Preventing Injuries to Under 5s publication on gov.uk and your setting's Health & Safety, Safeguarding policy will also be useful.
Hope this helps a little xx
