Why should workers avoid drinking directly from water sources in the field?

Workers should avoid drinking directly from water sources in the field primarily to prevent exposure to pathogens and chemicals. Natural water sources can be contaminated with harmful microorganisms such as bacteria, viruses, and protozoa, which can lead to serious health issues, including gastrointestinal infections and other diseases. Additionally, water sources may contain pollutants from agricultural runoff, industrial discharges, or other environmental contaminants that pose health risks.

By avoiding drinking directly from these sources, workers significantly reduce their risk of illness and ensure their safety and well-being during field operations. This practice is essential for maintaining overall health, particularly in settings where access to safe drinking water is limited, and proper hydration is crucial for performance and productivity.
