A Risk Level: High indicates a significant potential for adverse health effects with repeated or prolonged exposure, requiring strict safety measures to protect individuals. This classification applies to environments where substances or conditions are present in elevated concentrations, such as industrial settings or during emergency response. Protective equipment, controlled access, ventilation systems, and training are mandatory. Public health agencies recommend minimizing exposure through engineering controls and administrative policies. While high risk does not mean inevitable harm, it signals the need for vigilance and adherence to safety protocols. These measures ensure that workers and the public can remain safe while performing necessary tasks, with continuous monitoring to reduce exposure over time.
