What is the recommended approach to repairing a plaster wall with potential asbestos risk?

Explanation:
When a plaster wall may contain asbestos, the priority is to minimize disturbance and dust that could release fibers. The best approach is to use an asbestos-free joint compound for patching and skim coats and to avoid sanding the area. Using an asbestos-free compound prevents introducing asbestos material into the repair, and avoiding sanding reduces airborne dust and exposure. Aggressive sanding can release asbestos fibers, removing the plaster and replacing it with drywall is more invasive and increases disturbance, and applying a sealant alone may hide damage without properly repairing or addressing fiber risk.
