What does ERPG-2 represent?

ERPG-2 stands for Emergency Response Planning Guidelines Level 2 and is specifically defined as the maximum airborne concentration of a substance that is likely to cause serious health effects or that could be life-threatening. This guideline assists emergency responders in assessing the potential impact of a hazardous material release and helps determine the necessary protective actions to safeguard public health.

When ERPG-2 is established for a particular substance, it reflects exposure conditions that could lead to significant and potentially severe health consequences in the population if the exposure occurs at or above this concentration. Therefore, understanding ERPG-2 is crucial for effective emergency planning and response, enabling responders to make informed decisions regarding public safety and health during a hazardous materials incident.
