Lead-Based Paint (LBP)• LBP was banned in 1978. Pre-1978 housing stock is “presumed LBP.”

• Intact LBP (covered by several layers of non-LBP) is generally not considered hazardous.

• LBP which is deteriorated or disturbed thru remodeling produces lead contaminated dust and lead contaminated soil.

California Department of Health ServicesChildhood Lead Poisoning Prevention Branch

Senate Bill 460Provides local agencies authority to order the abatement of identified lead hazards. (Health and Safety Code sec. 105251-105256)

Amended the State Housing Law making lead hazards a housing code violation (Health and Safety Code sec. 17920.3)

Requirements for Lead Hazard Evaluation (testing)

• Must be a DHS-certified Inspector/Assessor to take dust, soil, or paint samples.

• Exceptions:1. Dust sampling to determine the adequacy

of containment.2. Compensation exemption

Abatement Options• Permanent measures: Door/window

replacement, paint removal or encapsulation. Soil removed or covered with concrete.

• Temporary measures: Paint stabilization and repair. Soil covered with grass or bark chips.

Visual Identification of Lead Hazards

Possible Lead Paint Hazard(presence of deteriorated “presumed lead based paint” on property built before 1978)

How to identify deteriorated How to identify deteriorated paint paint

To identify deteriorated To identify deteriorated paint, you will need to paint, you will need to answer this question answer this question Is Is the paint peeling, the paint peeling, chipping, chalking or chipping, chalking or cracking?cracking? If the answer If the answer to this question is yes, to this question is yes, then the paint should be then the paint should be considered deteriorated. considered deteriorated.

Identify areas where Identify areas where deteriorated paint is common deteriorated paint is common

You should look for deteriorated paint on all You should look for deteriorated paint on all painted building components, especially any painted building components, especially any exterior and interior walls, windows, or trim exterior and interior walls, windows, or trim damaged from a roof or plumbing leak. Also look damaged from a roof or plumbing leak. Also look on surfaces that experience friction or impact on surfaces that experience friction or impact When two surfaces slide across each other or When two surfaces slide across each other or strike one another, the painted surface may strike one another, the painted surface may become deteriorated become deteriorated Examples of friction and impact surfaces are Examples of friction and impact surfaces are doors, windows, floors, and trim areas doors, windows, floors, and trim areas

Is there anything else you Is there anything else you should look for? should look for?

When performing a visual assessment, you should also When performing a visual assessment, you should also look for: look for: Paint chips or dust from painting activities that were not Paint chips or dust from painting activities that were not cleaned up cleaned up Paint residue on the floors (this paint might be a hazard Paint residue on the floors (this paint might be a hazard for small children) for small children) Evidence of paint chips in the soil near Evidence of paint chips in the soil near driplinesdriplines on on exterior surfaces exterior surfaces

Peeling Peeling

Peeling paint is always considered to be deteriorated. Peeling paint is often caused by moisture or poor preparation of the surface before painting. This may affect small or large areas

Chipping Chipping

All chipping paint should be considered to be deteriorated. Chipping often is a result of impact to the painted surface Chipping paint may also be caused by poor surface preparation or paint failure

CrackingCracking

This photo shows a different form of cracking on a column base. This paint may start chipping soon. This type of cracking is considered deteriorated paint and must be repaired.

Chalking Chalking Some paints were designed to chalk as a method to keep the paint surface clean. If these paints contain lead, the chalking will also contain lead. You should consider chalking paint to be deteriorated if you can see evidence of chalking on the surfaces below the paint or on the ground.

In summary, deteriorated paint is: In summary, deteriorated paint is:

Unsafe Work Practices:

Disturbing Presumed Lead-Based Paint w/out Containment

(a) “Presumed LBP” = Pre-1978 surface coating

(b) “Containment” = Method to contain lead hazards in work area (e.g. plastic tarps)

Unsafe Work Practices…never dry sand, burn, or dry scrape lead-based paint

Unsafe Work Practices Can Create Lead Hazards

What Is Containment?What Is Containment?“Containment” means a system, process, or barrier used to contain lead hazards inside a work area such as described in “Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing,” U.S.Departmentof Housing and Urban Development, June 1995, Chapter 8, “Containment and Barrier Systems,” Table 8.1, Table 8.2, and Table 8.3, or “Guide for Containing Surface Preparation Debris Generated During Paint Removal Operations,” Society for Protective Coatings, Technology Guide 6, October 1, 2004
