Risk Assessment Process and Report Preparation
The on-site sequence
A risk assessment answers: is there a hazard, who is exposed, and by what pathway? It begins with an occupant interview (ages, pregnancy, pica and hand-to-mouth behavior, occupancy patterns, renovation history, water use, occupation/hobbies) combined with a visual assessment of paint condition (deteriorated paint is itself a hazard), moisture and surface damage, dust, soil, and water sampling as appropriate, and a review of any prior inspection data.
Evaluation logic
The assessor integrates: paint condition and whether LBP is present; dust-lead loadings versus hazard standards; bare soil lead versus standards; identified pathways (a child's accessible floor, a rubbing door, a deteriorated sill above a crib); and the likelihood and severity of exposure. Then hazards are ranked so recommendations are actionable.
Report elements
A defensible report includes: property and unit identification; dates and personnel/certification; scope and limitations; methods and instrument calibration; sampling locations (with a diagram or clear locator), lab results and their standards; hazard identification and ranking; exposure-pathway narrative tied to occupants; recommendations (interim controls, abatement, specialized cleaning, education, reevaluation); and the signatures, dates, and disclaimer that the assessment reflects conditions at the time of inspection.
Common traps
Expecting zero findings to mean "no report needed," or writing recommendations that do not match the identified hazard (e.g., recommending encapsulation for a dust hazard). Another trap: treating the inspection as the deliverable - an inspection produces LBP locations; the risk assessment produces hazard conclusions and recommendations.
Worked example
Deteriorated LBP on a friction door and elevated floor dust in a toddler's bedroom: the hazard is not merely "LBP present" but the pathway - friction wear generating dust where the child plays. Recommendations address source control (repair/stabilize the door), dust removal, and reevaluation.
