Hello, Should I use on or at ? On /at 02.May.2009 accident, we understood that we are weak in many areas. I know that with days, we should use "on". But, the noun after the date (accident) makes me doubt.
I'm afraid we need a little more context and background.[/quote]
An accident happened in my place of work. Much later on, when analyzing the reasons and causes, one of my colleagues wrote that sentence in his letter to safety officer. He meant that this accident showed that we had weaknesses that we didn't know until we faced the accident. For example: there were not enough fire extinguishers. We did not have all local emergency phone numbers handy. The fire extinguishers had not been installed in a suitable place.etc.
