Backflow Prevention Practice Exam

What type of hazard might require a cross-connection control program?

1. Low pressure issues

2. High-hazard processes

3. Normal drainage

4. Routine repairs

The correct answer is: High-hazard processes

A cross-connection control program is essential in preventing contaminants from entering the potable water supply through cross-connections. High-hazard processes often involve substances that can pose significant health risks if they were to contaminate drinking water. Examples include industrial activities, chemical manufacturing, and medical or laboratory environments where harmful chemicals are used. Implementing a cross-connection control program in these high-hazard situations ensures that appropriate measures are in place to prevent backflow from occurring. This may include the installation of backflow prevention devices, regular testing and maintenance of those devices, and ongoing employee training about the risks associated with cross-connections. In contrast, the other options do not suggest situations where the risk of contamination through cross-connections is as critical. Low pressure issues, normal drainage, and routine repairs, while they may pertain to general plumbing and system functionality, do not inherently involve hazardous materials that could threaten public health in the way high-hazard processes do. Hence, a cross-connection control program is primarily required in environments where the potential for severe contamination exists due to high-hazard operations.
