Certified Fire Protection Specialist (CFPS) — Question 34

A waste material with which of the following characteristics is considered a hazardous waste under the United States Federal Resource Conservation and Recovery Act (RCRA)?

Answer options

• A. PH ≤ 2 or ≥ 12.5, or a liquid flashpoint of 140°F (60°C) or less
• B. PH ≤ 2 or ≥ 12.5, or a liquid flashpoint of 100°F (37.7°C) or less
• C. PH ≥ 7 or ≤ 11, or a liquid flashpoint of 140°F (60°C) or less
• D. PH ≥12.5, or a liquid flashpoint of 200°F (93.3°C) or less

Correct answer: D

Explanation

The correct answer is D because hazardous waste is defined by its pH levels and flashpoints, and a pH of 12.5 or higher or a flashpoint below 200°F indicates a significant risk. Options A, B, and C do not meet the RCRA hazardous waste criteria, as their pH or flashpoint values fall outside the specified thresholds.
