What is the primary hazard of using water from non-potable sources during firefighting?

Using water from non-potable sources during firefighting poses significant health risks due to the potential for contamination. Non-potable water can contain harmful pathogens, chemicals, or pollutants that may lead to serious health issues for firefighters and bystanders. This contamination can occur through contact with skin, inhalation of aerosols, or ingestion, especially during the chaos of a fire response. These health risks underscore the importance of ensuring that water used in firefighting is safe and clean.

In comparison, while insufficient pressure, equipment damage, and slower response times are valid concerns associated with water sourcing and firefighting operations, they do not carry the same immediate health implications as contamination. The critical nature of ensuring the safety of personnel and the public is why contamination stands out as the primary hazard when utilizing non-potable water sources.
