Which is a key strategy for controlling a hazardous materials leak?

Using absorbent materials or plugs to contain the leak is a key strategy for controlling a hazardous materials leak because it directly addresses the source of the leak and helps to limit the spread of hazardous substances. This approach aids in minimizing environmental contamination and exposure risks to personnel. Absorbent materials can soak up liquids, helping to prevent them from spreading and creating larger hazards, while plugs can physically block or fill the leak source to stop further release.

In contrast, while evacuating personnel from the area is a vital safety measure for ensuring the safety of individuals nearby, it does not directly control the leak. Applying immediate chemical neutralizers can be helpful in some cases, but timing and knowledge of the chemical involved are crucial since improper use could lead to more hazardous reactions. Utilizing high-pressure water jets may inadvertently spread the hazardous materials rather than contain them, potentially worsening the situation. Therefore, using absorbent materials or plugs is a proactive and effective method for controlling leaks in hazardous materials incidents.
