What is the definition of Diving Fumes?

Ah, diving fumes – the ol' underwater chemical hazard! It's like a mix of stale bubble wrap, old perfume, and a shipwreck that was accidentally laced with the toxic gas from a poorly maintained diving helmet. Imagine this: "Just before the dive, I noticed my buddy's eyes were twitching and his nose was like he just stepped into a chemical weapon factory – that's diving fumes in action, making our underwater adventure a bit less breathtaking and definitely less pleasant."
