Which of the following is true concerning the proper procedure for dilution of a spill?

• A. Dilution is effective on its own
• B. Dilution may be effective when combined with other containment tactics
• C. Dilution should only be used for solid spills
• D. Dilution can help in removing the spill from the area

Answer: (B)

The correct answer regarding the proper procedure for dilution of a spill is that dilution may be effective when combined with other containment tactics. This approach acknowledges that while dilution can reduce the concentration of hazardous materials, it is most effective when used in conjunction with methods such as containment, absorption, or other remediation strategies.

Using dilution alone may not adequately address the risks, especially for hazardous materials that can cause environmental harm even when their concentration is reduced. Therefore, the combination of techniques allows for a more comprehensive and safer response to spills, ensuring that the material is properly managed and the impacted area is adequately treated.

Other options suggest either an overconfidence in the effectiveness of dilution alone or propose incorrect limitations on its application. For example, stating that dilution is effective on its own overlooks the potential dangers and complexities involved in handling hazardous spills, while asserting dilution should only apply to solids misrepresents its relevance to various spill types. The idea that dilution can help remove the spill from the area lacks context since removing hazardous materials often requires more than just diluting and may lead to further spread if not managed correctly.
