I am not satisfied with your report especially preventive actions.
What did you do to prevent similar accident?
Even the report will not be submitted to anybody, you shall mention and implement more practical and effective measures.
In addition, there are so many activities and potential risks as well for Arch Lining Works.
And some near misses have occurred already.
They may be sign of serious accident.
You shall study from such incidents and take actions to prevent accidents.
I request you to summarize the incidents already occurred and likely to occur and how to prevent them.
Please take action.
Regards,
