If you work in construction, it's common to encounter asbestos, lead, and other hazardous materials during remodeling or deconstruction. When that happens, follow a few straightforward steps to protect people and the job schedule.
Clear the area
If you find suspected asbestos, clear the area immediately and keep people away until it is assessed. While lead exposure often causes harm only after repeated contact, even small asbestos disturbances can release dangerous fibers.
Report
Report your findings promptly to the appropriate local or federal agency and to your client so occupants and workers are aware of potential exposure. The responsible agency will usually run tests to confirm whether the material is asbestos or something else.
For asbestos and other hazards: get a professional
Only certified professionals should remove asbestos. Even if you have training, you must notify the proper authorities before performing removals in many jurisdictions.
For guidance on safety practices and regulations for construction jobs, see Hazardous Materials and Safety in Construction.
For lead: proceed with caution
In many places you can remove lead yourself, but the process is tricky and requires strict dust control. Anyone working with lead should wear a fitted dust mask or respirator, goggles, and gloves, and should seal and clear the work area to prevent dust spread.
Sweep and clean thoroughly using wet methods or HEPA-equipped equipment before reoccupying the space.
Replace
After removing hazardous materials, consider why the material was there in the first place. Asbestos, for example, was often used for fire resistance and must be replaced with a safe alternative such as fiber-cement or other noncombustible materials.
For coverage considerations related to building materials and work that involves roofing or siding, see Roofing, Siding and Insulation Materials Insurance.
If your project involves chemical or corrosion hazards beyond asbestos or lead, you may want to review guidance on broader workplace hazards and liability: Construction and Workplace Hazards — HazMat, Chemicals, Corrosives & Liability.
Finally, monitor the health of yourself and your crew over time. The greatest risk is prolonged exposure, so document incidents and follow up medically if anyone shows symptoms.
If you need help navigating insurance or next steps, consider talking to an agent.
Frequently Asked Questions
How can I tell if a material is asbestos?
Only a laboratory test on a properly collected sample can confirm asbestos; assume a material is hazardous and restrict access until testing is complete.
Do I need certification to remove asbestos?
Yes—most jurisdictions require certified asbestos removal professionals and notifications to authorities before removal work begins.
Can I remove lead paint myself?
In many areas homeowners or contractors may remove lead paint, but strict precautions for dust control and personal protective equipment are essential.
What immediate steps should I take after a suspected exposure?
Stop work, isolate the area, notify authorities and the property owner, and arrange for testing and professional remediation if needed.
