Which symbol denotes a hole?

Which symbol denotes a hole?

• A. H
• B. P
• C. TOX
• D. CHM

Answer: (A)

In damage control diagrams, you use symbols that convey fast, precise meaning about openings and hazards. A hole is an actual breach in the hull, so marking it with H gives an unmistakable, quick cue that this location is an opening that must be blocked or pumped to prevent uncontrolled flooding. The other marks point to different things: P is more about piping or pumps, while TOX and CHM indicate hazardous conditions like toxic gases or chemicals. Because H directly identifies the hull breach, it’s the correct symbol for a hole.
