Water rescue may be attempted if all of the following are true EXCEPT ________.

Attempting a water rescue hinges on several critical factors to ensure both the rescuer's safety and effectiveness in aiding the victim. The correct answer indicates that if the rescuer is unable to swim, it is inadvisable to attempt a rescue. This is paramount because a rescuer who cannot swim puts themselves at significant risk, potentially leading to two victims instead of one.

The other factors are essential components of making a decision to proceed with a rescue. If the victim is in distress, it indicates a need for immediate intervention. Having help on the way means that professional assistance is being summoned, which can provide a safety net for the rescuer. Additionally, ensuring safe conditions is crucial to prevent further incidents during the rescue operation. Each of these aspects is integral to effective emergency response, but the inability to swim fundamentally limits the rescuer's ability to assist without jeopardizing their own safety.
