Which action should be prioritized when dealing with a hazardous material spill?

The priority in dealing with a hazardous material spill is to call for professional help and isolate the area. This is crucial because hazardous materials can pose immediate risks to health and safety, not only for those directly involved in the spill but also for bystanders and the environment. By calling for professional help, you ensure that trained responders with the right equipment and expertise are on their way to manage the situation safely and effectively.

Isolating the area prevents others from entering a potentially dangerous environment, minimizing the risk of exposure and further contamination. This is a critical step that ensures that everyone remains safe until professionals can handle the spill appropriately.

While determining the source of the spill is important for remediation efforts, it should only be attempted by trained professionals. Evacuating the area is also a necessary step, but without isolating the area and calling for help, the situation could escalate. Documentation is essential for later analysis and reporting, but it is not a priority during the initial emergency response. The immediate focus must always be on safety and containment.
