It seems that the Twitter post you provided does not mention anything related to maintenance report feedback for a public flat house in Singapore. The post contains a list of chemicals, including sulphuric acid and hydrogen peroxide, which could potentially be used for harmful purposes, but it does not provide any context or information that would suggest it is related to a maintenance report feedback. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house.
