Lead
Many buildings built or renovated before 1978 have lead-based paint applied
to some interior or exterior surfaces. Paint containing 0.5 percent or more
lead by weight or 1 mg/cm2 or more lead by x-ray fluorescence is considered
to be lead-based paint.
- Contractors employed by the university should request from
the Project Manager the location of known lead-containing building
materials in the work area(s) to which they are assigned.
- Contractors that disturb lead-based paint during the course of work
should ensure all work is in compliance with the OSHA
Lead in Construction Standard, 29 CFR 1926.62, including
controlling exposures below the permissible exposure limit and providing
biological monitoring for employees, as needed.
- Contractors that disturb lead-based paint during the course
of work should take all necessary precautions to protect University
employees, students and visitors from exposure to lead dust or contamination.
Such
measure may include using plastic sheeting to isolate the work
area, using wet techniques, washing with trisodium phosphate, and/or
using
a HEPA vacuum.
- Where the work area is an area normally occupied or frequently
visited by children under 6 years old or pregnant women, EHS should
be contacted after the work area has been cleaned to perform clearance
testing.
The Contractor shall continue cleaning efforts until sampling results
indicate the lead dust levels are less than or equal to 100 micrograms
per square foot on floor surfaces and less than or equal to 500 micrograms
per square foot on interior window sills, as appropriate.
- Contractors employed to provide abatement of a lead paint hazard
should be licensed by the State of New Jersey to provide such services.
All work should be performed in accordance with applicable laws and
regulations, including N.J.A.C. 5:17, Lead Hazard Evaluation and Abatement
Code.
- In many cases, lead paint chips are considered hazardous
waste by the U.S. Environmental Protection Agency. Contractors shall
ensure
that wastes containing lead-based paint, including paint chips, are
disposed in accordance with federal and state regulations. All hazardous
waste
generated from University facilities must be disposed of by contacting
Princeton University Environmental Health and Safety (EHS).
