Questions & Answers about kono mondai wa anzen ni kanrenshite iru.

Why is は used after 問題?

は marks 問題 as the topic of the sentence.

So この問題は means something like:

• As for this issue...
• This issue...

In English, we often just start with the subject directly, but Japanese often separates the topic from the rest of the statement.

You could think of the structure as:

• この問題は = as for this issue
• 安全に関連している = is related to safety

What exactly does この問題 mean here? Is it problem, issue, or question?

問題 can mean several related things depending on context:

• problem
• issue
• question on a test
• matter or concern

In this sentence, issue or problem is probably the most natural translation.

So この問題 is likely:

• this issue
• this problem

If it were talking about homework or an exam, it could also mean this question.
