When transporting chlorine in cargo tanks, having an emergency kit for controlling leaks is a critical requirement. Chlorine is a highly toxic and corrosive substance that can pose serious health risks if there is a leak or spill. An emergency kit designed for leak control typically includes items such as plugs, clamps, or absorbent materials specifically suited for handling chlorine. This kit allows the driver or the response team to take immediate action to contain and control the leak, minimizing the potential impact on public safety and the environment.

The other options may not directly pertain to the immediate safety measures required for transporting chlorine. While an emergency contact number is important for communication during incidents, it does not address leak containment directly. A secondary containment system might be a consideration in some shipping practices, but it’s not specifically mandated within the context of cargo tanks for chlorine. Lastly, a personal flotation device is not relevant to the handling or transportation of chlorine since it is not a waterborne operation and does not apply to this hazardous material.
