Is it necessary to install cofferdams within the torch area?

As the title suggests, does the torch system require the installation of cofferdams and sump pits to drain rainwater and water from surface washing? Thank you! Please explain the reason, thank you! If the answer is good, give it a rating!
It depends on your medium, such as corrosion, toxicity, and so on. Of course, from an environmental perspective, it would be better to have such structures in place; however, the wastewater collected cannot be easily treated, and generally no dikes are constructed.
Now, a three-level prevention and control system is required; the torch area, as a potential source of pollution, should be enclosed with dikes, and separate systems for rainwater and wastewater must be established.
It’s obvious that wherever there’s a risk of flammable liquids leaking and spreading, dikes need to be installed; otherwise, how can you allow the liquids to flow around freely?
