LEAD ABATEMENT study guide
10 ug/ft2 - floors
10 ug/ft2 - interior windows, sills or stools
100 ug/ft2 - window troughs or window well
50 ug/m3 - Osha permissible exposure limit
30 ug/m3 - Osha action level - Requires 2 hr training & 1 blood test
Drinking Water Levels - 15 ppb (parts-per-billion)
Lead soil levels - 400 ppm (parts-per-million)
Lead soil Levels (2) - 5000 ppm (parts-per-million) HUD requires abatement of soil
hazard
BLOOD LEAD LEVELS - Children - 5 ug/dl requires investigation
, LEAD ABATEMENT study guide
BLOOD LEAD LEVELS - Children (2) - 20 ug/dl = Lead poisoned
Blood Lead Levels Adults - 20 ug/dl = concern
Blood Lead Levels Adults (2) - 30 ug/dl = removed from work
Blood Lead Levels Adults (3) - 15 ug/dl = back to work level
Defined forms of abatement - Removal, Enclosure, Encapsulation
How long does encapsulant last? - 20 years
Lead Hazards! - 1. Contaminated Soil
2. Contaminated Dust
3. Lead Based Paint
4. LBP Friction Surface
5. LBP Impact surface
6. LBP chewable surface
