Which term is used to refer to the immediate effects of exposure to hazardous substances?

The term that refers to the immediate effects of exposure to hazardous substances is "acute hazard." This term is used to describe situations where exposure results in harmful effects that appear swiftly after contact, often within hours or days. Acute hazards can cause immediate health issues, such as poisoning or acute respiratory distress, which can be life-threatening or lead to significant health impacts.

In safety and health contexts, understanding acute hazards is crucial for developing appropriate response strategies, hazard communication, and protective measures. Identifying these immediate risks allows for effective training and readiness in handling hazardous substances, ensuring that workers can respond promptly to potential emergencies. Establishing procedures based on recognizing acute hazards helps organizations safeguard the health of their employees and maintain regulatory compliance.
