If a chlorine leak occurs, where will chlorine gas accumulate? Near the ____________ of the tank.

• A. Top
• B. Bottom
• C. Side
• D. Center

Answer: (B)

Chlorine gas is heavier than air, so it tends to settle into the lowest point after a release. In a tank, a leak will cause chlorine to pool at the bottom, creating a concentrated and hazardous atmosphere there. You wouldn’t expect it to accumulate at the top or in the middle because the gas naturally sinks toward the lowest area. This behavior is why safer response relies on proper ventilation and monitoring at low points, rather than expecting any buildup at higher elevations.
