What should be the primary objective during the initial response to a hazardous material spill?

Ensuring the safety of all human life is the primary objective during the initial response to a hazardous material spill because the foremost concern in any emergency situation is protecting people from harm. This involves assessing the risks to individuals in the vicinity, including responders and the public, and taking appropriate actions to evacuate and provide medical assistance if needed.

The safety protocols established in hazardous materials response prioritize human health over containment or identification of the substance involved. While containing the spill, documenting details, and identifying the source are critical steps in managing the incident, they come after ensuring that those nearby are safe from exposure to harmful substances. Hence, focusing on human safety first establishes a secure environment from which other response measures can be effectively implemented.
