Can a work area be reoccupied before dust sample results are returned?

Can a work area be reoccupied before dust sample results are returned?

• A. Yes, after a visual inspection shows no issues.
• B. Yes, if the renovator approves.
• C. Only after a clearance certificate is posted.
• D. No

Answer: (D)

Reoccupancy after renovation depends on verified evidence that lead dust levels are below the acceptable limit. Visual checks or someone’s approval do not guarantee that dust is absent or at safe levels, because lead dust can be invisible and spread during cleaning. Dust wipe sampling provides an objective measurement, and the area must meet the clearance standard before it’s considered safe to use again. The formal signal that reoccupancy is allowed is the clearance certificate being posted, which happens only after the samples are analyzed and meet the required limit. So you should not reoccupy before the dust results are returned; wait for the clearance certificate to be posted to confirm it’s safe.
