How should rescuers approach a hazardous materials leak to ensure safety?

Approaching a hazardous materials leak at a distance is crucial for ensuring the safety of rescuers. This strategy allows for the assessment of the situation without putting themselves directly in harm's way or exposing themselves to potential toxic substances, explosive vapors, or chemical reactions. By maintaining distance, rescuers can evaluate the type and extent of the leak and make informed decisions about necessary actions and response measures.

Staying at a distance also provides an opportunity to implement protective measures without immediate exposure. This approach aligns with principles of safety in hazardous materials response, where the primary objective is to minimize risk while effectively managing the incident. Once a safe distance is established, further actions can be taken based on analysis and assessment of the leak, potentially using remote tools or equipment to gather additional information if necessary.

Overall, the priority is to protect lives—both of rescuers and bystanders—by minimizing direct exposure to the hazardous environment.
