What is a hazardous materials survey?

A hazardous materials survey checks a building for risky stuff that could harm health or the environment if disturbed. It usually focuses on things like asbestos, lead paint, or some chemical residues that were common in older buildings. The point is to figure out what's there, where it is, and if it needs to be dealt with. This isn't just a formality; it helps owners and contractors make smart choices before doing any work like repairs or demolition. If any risky materials are found, the report will say how to handle or get rid of them safely.
