need help finding makaton signs

[lavywith3]

dd3 has no expressive language at 3yrs and using makaton but basically using something special to teach myself as can't afford training. Specialist teacher set iep targets today at nursery including embedding sign for 'dangerous' to help her recognise danger around but noone knows the sign for dangerous, including her!! Can anyone help?

in BSL it's right hand out flat, palm facing to your left and fingers pointing upwards, tap hand against forehead.

Thank you. Tbh think it doesn't really matter as long as we use same sign at home & nursery so will use that :)
