SECTION 02 83 33.13

LEAD-CONTAMINATION CLEANING AND DISPOSAL SPECIFICATION

VAMC – DALLAS, TX – HERZOG BUILDING, FORMER GUN RANGE ROOMS

PART 1 - GENERAL

1.1 SUMMARY

A. Section Includes:

1. This specification pertains to the decontamination of the Former Gun

Range Rooms located on the 2nd floor of the Herzog Building next to the VAMC located in Dallas, Texas. In September, 2015, wipe samples were collected from the floor of the Former Gun Range. The results indicated that the floor, walls, and any equipment, shelving, etc.

located in these rooms are potentially contaminated with lead dust.

All walls, the ceiling, floors, shelving, equipment, etc. located in the Gun Range rooms must be decontaminated. If furniture or other equipment exists inside the work area that is not built-in (may be furniture being stored in this area), Contractor will clean these items and remove them from the room(s) prior to remediation occurring. TCLP will not be conducted on this project (it is impossible to obtain enough lead dust to properly sample for TCLP analysis). All waste will be assumed hazardous, and disposed of at a landfill that accepts hazardous waste.

1.2 RELATED WORK

A. NOT APPLICABLE TO THIS PROJECT

1.3 DEFINITIONS

A. Action Level: Employee exposure, without regard to use of respirator, to an airborne lead concentration of 30 micrograms(µ) per cubic meter

(m3) of air determined as an 8-hour Time-Weighted Average (TWA). As used in this section, ”30 micrograms per cubic meter of air" refers to OSHA

29 CFR 1926.62 Lead in Construction Action Level (AL).

B. Area Monitoring: Sampling of lead concentrations within lead control area and inside physical boundaries which are representative of airborne lead concentrations which may reach breathing zone of personnel potentially exposed to lead.

02 83 33.13 - 2

C. Breathing Zone: Area within hemisphere, forward of shoulders, with 150 mm to 225 mm (6 to 9 inches) radius and center at nose or mouth of employee.

D. Certified Industrial Hygienist (CIH): As used in this section, refers to an Industrial Hygienist Certified in the Comprehensive Practice of

Industrial Hygiene by the American Board of Industrial Hygiene and

Board for Global EHS Credentialing, employed by Contractor.

E. Change Rooms and Shower Facilities: Rooms within designated physical boundary around lead control area equipped with separate storage facilities for clean protective work clothing and equipment and for street clothes which prevents cross contamination.

F. Competent Person: Person capable of identifying lead hazards in work area and authorized by contractor to take corrective action. Meets the

OSHA definition of Competent Person.

G. Decontamination Room: Room for removal of contaminated personal protective equipment (PPE).

H. Eight-Hour Time Weighted Average (TWA): Airborne concentration of lead averaged over 8-hour workday to which an employee is exposed.

I. High Efficiency Particulate Air (HEPA) Filter Equipment:

HEPA filtered vacuuming equipment with UL 586 filter system capable of collecting and retaining lead-contaminated paint dust. HEPA filter means 99.97 percent efficient against 0.3 micron (0.012 mil) size particles.

J. Lead: Metallic lead, inorganic lead compounds, and organic lead soaps.

Excluded from this definition are other organic lead compounds.

K. Lead Control Area: Enclosed area or structure with full containment to prevent spreading lead dust, paint chips, and debris from lead-based paint removal operations. Lead control area is isolated by physical boundaries to prevent unauthorized entry of personnel.

L. Lead Permissible Exposure Limit (PEL): Fifty micrograms per cubic meter of air (50 µg/m3) determined as an 8-hour TWA as determined by

29 CFR Part 1926.62. When employee is exposed for more than 8-hours per work day, determine PEL by the following formula. PEL micrograms/cubic meter (parts per million) of air = 400/No. of hrs. worked per day.

M. Personnel Monitoring: Sampling of lead concentrations within employee breathing zone to determine 8-hour time weighted average concentration according to 29 CFR Part 1926.62. Take samples that are representative of the various employee's work tasks.

02 83 33.13 - 3

N. Physical Boundary: Area physically roped or partitioned off around enclosed lead control area to limit unauthorized entry of personnel. As used in this section, "inside boundary" shall mean same as "outside lead control area."
