It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house in Singapore. The term "working risk" is not a common term used in maintenance reports, and it does not provide any specific information about a facility or infrastructure that needs maintenance. Therefore, the post does not match any of the categories I provided in my previous answer.
