To conform with "best practice", can you be signalman for a crane operation and stand-by for a colleague who has entered a cargo tank at the same time?
Yes.
No.
Normally no, but if we are in a hurry to get lots of jobs done before entering port and the Chief Mate knows about it, then it is alright to do so.
Yes, provided I have radio contact with the man inside the tank.
I don't know
No.
In order to determine the correct answer to this question, we need to refer to best practices and industry standards for crane operations and ensuring safety during cargo tank entries.
To conform with best practices, it is generally not acceptable for a signalman to stand-by for a colleague who has entered a cargo tank at the same time. This is because it is important to prioritize safety and ensure that all necessary precautions are taken during crane operations and tank entries.
However, there is a mention of a specific scenario where it might be considered acceptable. The scenario mentioned is when there is a need to complete multiple tasks before entering port and the Chief Mate is aware of and approves the arrangement. It's important to note that this seems to be an exceptional case and not a standard practice.
If radio contact is established between the signalman and the person inside the tank, it may be possible to have a signalman stand-by. This allows for communication and coordination, increasing safety during the operation.
Without more information, it is not possible to definitively select one answer. It would be best to consult specific industry regulations, guidelines, and the organization's safety policies to determine the appropriate course of action in such a situation.
