When considering a self-help project in a facility built before 1978, it is vital to verify hazards that are specific to older buildings. These structures are particularly at risk for containing materials that can pose significant health risks, including asbestos insulation and paint containing lead.

Asbestos insulation is a common material in buildings constructed prior to 1978 and can release harmful fibers into the air if disturbed, leading to serious respiratory issues and diseases like asbestosis and mesothelioma. Verification of its presence is crucial before any renovations or disturbances in the area.

Lead paint is another major concern; homes built before 1978 are likely to have been painted with lead-based paints. This presents a serious risk, particularly during renovations that may create dust or chips that can be ingested or inhaled, especially by young children. Both of these hazards necessitate thorough field verification to ensure safety before proceeding with any projects.

Other options may mention hazardous components like radon, carbon monoxide, chemical spills, and mold, but these do not hold the same level of historical association with pre-1978 buildings as asbestos and lead paint do, making them less critical to verify in this specific scenario.
