Work carried out in a dwelling or building constructed before 1 January 1949 that causes dust emissions is presumed to be at risk within the meaning of article L. 1334-11 if the measures taken to protect occupants are inadequate.
The presumption of risk is lifted when a lead exposure risk report certifies that the coverings concerned by the work do not contain lead in concentrations exceeding the thresholds defined by the order referred to in article L. 1334-2 or when a dust analysis as defined in 2° of article R. 1334-8 concludes that the lead concentration in dust on the ground does not exceed the threshold referred to in this article.
The Prefect will draw up a statement of the expenses incurred by the precautionary measures referred to in article L. 1334-11 and will issue an enforceable collection order to the owner, co-ownership association or operator of the defaulting accommodation.
