What should be prioritized as the first line of defense against chemical spills?

Prioritizing prevention through proper handling and storage serves as the most effective first line of defense against chemical spills. Effective prevention strategies reduce the likelihood of spills occurring in the first place. This includes implementing strict protocols for storing hazardous materials, ensuring containers are sealed, labeling chemicals accurately, and training personnel in safe handling practices. These proactive measures create an environment where spills are less likely to happen, thereby safeguarding both personnel and the surrounding environment from potential harm.

On the other hand, while immediate evacuation, notifying authorities, and using absorbent materials are all important response measures, they represent steps to be taken after a spill has occurred. Evacuation focuses on safety after a hazardous situation has developed, and notifying local authorities often involves external response and remediation efforts. Using absorbent materials is a strategy for managing spills, but prevention is always more effective and desirable than response.
