When encountering a spill or hazardous material, what should be the immediate priority?

The immediate priority when encountering a spill or hazardous material is to control the situation. This involves assessing the spill to prevent further harm to individuals and the environment. Control measures may include securing the area to prevent access, establishing a perimeter, and ensuring that appropriate safety protocols are in place to minimize exposure risks to bystanders and responders.

By prioritizing control of the situation, responders can mitigate potential hazards, protect lives, and limit the spill's impact on the environment. Once the situation is controlled, responders can then assist injured parties, document the scene, and contact environmental agencies as necessary for cleanup or further action.
