Close to safe area in hazardous Scottish island (7)

I believe the answer is:

eriskay

'scottish island' is the definition.

'close to safe area in hazardous' is the wordplay.
'close to' says to take the final letters (the close/ending of).
'area' becomes 'a' (maths abbreviation).
'in' means one lot of letters goes inside another.
'hazardous' becomes 'risky' ('risky' can be a synonym of 'hazardous').
The last letter of 'safe' is 'e'.
'a' placed within 'risky' is 'riskay'.
'e'+'riskay'='ERISKAY'

I've seen this clue in The Guardian.
