Which methods are effective for containing hazardous spills?

Containment bunds and absorbent materials are highly effective methods for managing hazardous spills. Containment bunds are barriers built around a spill to prevent the hazardous substance from spreading beyond the immediate area. They effectively isolate the spill, allowing for controlled cleanup and minimizing environmental impact. Absorbent materials, such as booms, pads, or granules, are used to soak up liquids, making it easier to remove the hazardous substance from the surface and reducing the risks associated with spills.

Using these methods not only facilitates safer response actions but also ensures compliance with regulations regarding hazardous materials management. Proper containment and absorption are critical in preventing further contamination of soil and water resources, thus helping to protect public health and the environment.

Other methods mentioned may not be as effective in the immediate containment of spills. For instance, water spraying may dilute a spill but can also spread hazardous materials, while evaporation and dilution techniques could result in harmful vapors or require further environmental controls. Immediate evacuation and clean-up are crucial steps in emergency response but do not address the initial containment of the spill itself.
