What chemical method of containment involves applying a second material to neutralize a hazardous material?

The correct answer is identified as neutralization because this method specifically involves employing a second material to chemically react with a hazardous substance, thereby neutralizing its potential danger. For example, in an incident involving an acid spill, a base can be applied to neutralize the acidity, converting it into a less harmful substance. This process is crucial for mitigating the effects of hazardous materials and safely educating responders on how to approach these situations effectively.

Neutralization is generally effective in cases where a chemical reaction can transform a hazardous substance into a non-toxic or less toxic form. This contrasts with other methods mentioned such as absorption, which involves soaking up the hazardous material to contain it, but does not change its chemical nature. Understanding the specific functions and applications of these methods helps responders effectively decide on the best course of action during HAZMAT incidents.
