LEAD HAZARD MITIGATION STANDARDS
Types of Hazards on Window Units
Deteriorated paint- any interior or exterior paint or other coating that is cracking, chipping, peeling, or chalking; or any paint or coating that is otherwise damaged or separated from the surface to which it was applied. Any chewable lead-based painted surface on which there is evidence of teeth marks.
Friction surface – Surface that is subject to abrasion or friction as it operates and lead dust is likely to occur around such surfaces. Treatment of friction surfaces is required only if there is evidence that the paint surface is subject to abrasion; and lead dust levels on the nearest horizontal surface underneath the friction surface are equal to or greater than the standards specified.
Impact Surface- Impact surface is damaged, abraded, rubbed, impacted or otherwise deteriorated. Paint on an impact surface that is damaged, abraded, rubbed, impacted or otherwise deteriorated requires remediation.
Lead Hazard Remediation Strategies
All lead-based paint, including pre-1978 painted surfaces required to be assumed positive, must be intact with no paint or coating on a damaged or deteriorated component; no surface which has loose, delaminating, flaking, peeling, chipping, chalking, or blistering paint; no paint that is otherwise becoming separated from the substrate; no paint which is abraded by friction or impact, shows evidence of teeth marks, or is damaged by water.
Historic windows units are comprised of parts with different functions, where the remediation plan is specific to their condition and use. Non-functioning units or parts without friction or impact can be mitigated through encapsulation and stabilization to eliminate chipping, peeling, flaking and/or chalking.
Lead Hazard Remediation Strategies include the following methods:
Enclosure- Lead-painted surface is covered with metal, plastic, or other approved material to prevent lead paint debris from being released.
Paint Removal & Refinishing- Removing lead-based paint to bare wood and coating with paint.
Replacement- Part is reproduced in-kind and refit into unit.
