What is considered a high hazard substance?

A high hazard substance is defined as a material that can adversely affect human health. This classification encompasses chemicals or biological agents that pose a significant risk of injury or illness upon exposure. Such substances may lead to serious health effects, including chronic health conditions or acute reactions, making their management and containment critical in preventing backflow incidents that could contaminate drinking water supplies.

The context of water quality and safety emphasizes the importance of identifying and managing high hazard substances to protect public health. Understanding this concept is crucial for professionals in backflow prevention and certification, as it informs their practices and compliance with safety regulations. By recognizing these hazardous substances, certified professionals can take appropriate steps to mitigate risks and ensure that the water supply remains safe for consumers.
