And HOLD that judgment!
As a teamleader you are responsible for (a part of) the operations. It is in your interest that it gets safely done. You do not pass judgment before the investigation is fully complete. Therefore, you will assist with the investigation on all fronts. Provide all relevant information, make people available for interviews.
Ask to be involved when recommendations are being composed, because they will need to be realistic and achievable and there is no-one better placed than you to determine this.
