Before collecting paint chip samples, what must you do to avoid elevated lead dust levels?

To ensure safety and minimize elevated lead dust levels prior to collecting paint chip samples, it is crucial to clean the area thoroughly. This step helps to remove any existing lead dust or contaminants that could skew the results of the sampling or pose health risks during the collection process.

Cleaning involves using appropriate methods to adequately remove dust and debris, especially in environments where lead-based paint is suspected. This not only protects the individuals conducting the sampling but also safeguards others who may enter the area afterward. While inspecting and measuring the area are important procedures in the overall assessment and risk management process, proper cleaning is essential for ensuring that the conditions are safe and accurate for lead testing.
