What is the maximum allowed reading for floor clearance tests after lead work?

• A. 10
• B. 50
• C. 100
• D. 400

Answer: (A)

The maximum allowed reading for floor clearance tests after lead work is 10 micrograms per cubic meter (µg/m³). This standard is in place to ensure that any residual lead dust has been thoroughly cleaned and does not pose a health risk to occupants, particularly vulnerable populations such as children and pregnant women. The threshold of 10 is based on guidance from health and environmental agencies aimed at minimizing lead exposure. Maintaining this level is crucial for ensuring safety and compliance with regulations governing lead remediation. Readings above this level would indicate that additional cleaning or remediation measures are required before the area can be safely occupied.
