EPA Lead Supervisor Course Practice Exam

HUD disturbance is considered when the area is more than how many square feet (interior and exterior)?

2 ft2 Interior / 2 ft2 Exterior 6 ft2 Interior / 20 ft2 Exterior 12 ft2 Interior / 12 ft2 Exterior 4 ft2 Interior / 4 ft2 Exterior

Correct Answer:

2 ft2 Interior / 2 ft2 Exterior

Explanation:

HUD disturbance is about when renovation work disturbs lead-based paint enough to require lead-safe practices. The trigger is a disturbance of more than 2 square feet on interior surfaces or more than 2 square feet on exterior surfaces. This small threshold is used to prevent the spread of lead dust during common home repairs. So, the correct threshold is 2 square feet both inside and outside. Disturbances exceeding this limit call for containment, proper cleanup, and lead-safe work procedures. The other numerical options represent thresholds from different regulatory contexts and do not define HUD disturbance in this setting.
