What is one of the important cutoffs for lead testing in multi-family homes built between 1960 and 1977?

In the context of lead testing for multi-family homes built between 1960 and 1977, the important cutoff is 11 parts per million (ppm). This threshold is significant because it aligns with regulations established to assess the potential for lead hazards in these properties. Homes constructed during this period often contain lead-based materials, and testing above this concentration indicates a greater likelihood of lead exposure risks to occupants, particularly children.

The value of 11 ppm represents a level where lead is considered a concern, prompting further action such as remediation or more thorough inspection. Understanding these cutoffs is critical for inspectors and property owners to ensure safety and compliance with environmental health standards. Thus, recognizing 11 ppm as the appropriate cutoff helps guide effective lead management strategies in eligible multi-family homes.
