Discussion on working inside containers.
Thread Content
A question from 611: For equipment and containers that are flammable, explosive, or toxic, it is necessary to perform purging before entering them for maintenance; work can only proceed after the analysis shows that the conditions are satisfactory. ( ) What are the rules here? Is this question correct? Isn’t isolation necessary? Is it not necessary to obtain a permit for working in confined spaces?
Simply put, it should be correct. It is necessary to obtain the relevant tickets; it is an additional condition.
The statement in the question is correct; there’s no need to go into further details. If we did, then the workers would also need relevant special operation certificates and things of that kind. Just look at the question alone.
Actually, this can be misleading; just going in to work inside the container comes with very strict requirements. Can it really be considered correct if it’s done separately? ? The samples were qualified at the time of sampling, but they were not isolated from the system – are accidents of this kind that common? .
It’s similar to expanding or contracting sentences – it can be extended as well – but it is correct in its own right. To claim that it’s incorrect without any isolation measures is wrong; after all, safety measures require things like issuing invoices, allowing the system to release pressure, shutting off power, ensuring ventilation, cooling down, and using purging methods – there are many other requirements as well!
Not all containers can be isolated, right? A space operation permit is mandatory; more specifically, there must be a dedicated person to supervise operations from outside
Correct, it’s just explained in a simpler way
