Notes: 1Employers may select respirators assigned for use in higher workplace concentrations of a haz-ardous substance for use at lower concentrations of that substance, or when required respirator use is independent of concentration. 2The assigned protection factors in Table 1 are only effective when the employer imple-ments a continuing, effective respirator program as required by this section (29 CFR 1910.134), including training, fit testing, maintenance, and use requirements. 3This APF category includes filtering face-pieces, and half masks with elastomeric face- pieces. 4The employer must have evidence provided by the respirator manufacturer that testing of these respirators demonstrates performance at a level of protection of 1,000 or greater to receive an APF of 1,000. This level of performance can best be demonstrated by performing a WPF or SWPF study or equivalent testing. Absent such testing, all other PAPRs and SARs with helmets/hoods are to be treated as loose-fitting face-piece respirators, and receive an APF of 25. 5These APFs do not apply to respirators used solely for escape. For escape respirators used in association with specific substances covered by 29 CFR 1910 subpart Z, employers must re-fer to the appropriate substance-specific standards in that subpart. Escape respirators for other IDLH atmospheres are specified by 29 CFR 1910.134 (d)(2)(ii).

1.3 DEFINITIONS

A. The following definitions relative to lead paint as used in this Section are offered:

1. ACTION LEVEL (AL): The allowable employee exposure, without

regard to use of respiratory protection, to an airborne concentration of lead over an eight (8) hour time weighted average (TWA), as defined by OSHA. The current action level is thirty micrograms per cubic meter of air (30 ug/m3).

2. AREA MONITORING: The sampling of lead concentrations, which is repre-

sentative of the airborne lead concentrations that may reach the breathing zone of personnel potentially exposed to lead.

3. BIOLOGICAL MONITORING: The analysis of a person's blood and/or urine,

to determine the level of lead concentration in the body.

4. CHANGE ROOM: An area provided with separate facilities for clean pro-tective work clothing and equipment and for street clothes, which prevents cross-contamination.

5. COMPETENT PERSON: A person employed by the Contractor who is capa-

ble of identifying existing and predictable lead hazards in the surroundings or working conditions, and who has authorization to take prompt corrective measures to eliminate them as defined by OSHA.

6. DANGEROUS LEVEL OF LEAD: A level of lead, when present in dried paint

or plaster, contains more than 0.50% lead by dry weight as measured by atomic absorption spectrophotometry (AAS) or 1.0 mg/cm2 as measured by on-site test-ing utilizing an x-ray fluorescence analyzer. (Term is specific to Commonwealth of Massachusetts regulations and HUD guidelines only)

7. EXPOSURE ASSESSMENT: An assessment conducted by an employer to de-

termine if any employee may be exposed to lead at or above the action level.

8. "HIGH EFFICIENCY PARTICULATE AIR" (HEPA): A type of filtering sys-tem capable of filtering out particles of 0.3 microns diameter from a body of air at 99.97% efficiency or greater.


9. LEAD: Refers to metallic lead, inorganic lead compounds and organic lead soaps. Excluded from this definition are other organic lead compounds.

10. LEAD WORK AREA: An area enclosed in a manner to prevent the spread of

lead dust, paint chips, or debris resulting from lead-containing paint disturb-ance.

taining a toxic level of lead.

12. PERMISSIBLE EXPOSURE LIMIT (PEL): The maximum allowable limit of exposure to an airborne concentration of lead over an eight (8) hour time weighted average (TWA), as defined by OSHA. The current PEL is fifty mi-crograms per cubic meter of air (50 ug/m3). Extended workdays lower the PEL by the formula: PEL equals 400 divided by the number of hours of work.

13. PERSONAL MONITORING: Sampling of lead concentrations within the

breathing zone of an employee to determine the 8-hour time weighted average concentration in accordance with 29 CFR 1926.62 and 29 CFR 1910.1025. Samples shall be representative of the employee's work tasks. Breathing zone shall be considered an area within a sphere with a radius of 18 inches and centered at the nose or mouth of an employee.

14. RESOURCE CONSERVATION RECOVERY ACT (RCRA): RCRA estab-

lishes regulatory levels of hazardous chemicals. There are eight (8) heavy met-als of concern for disposal: arsenic, barium, cadmium, chromium, lead, mercu-ry, selenium, and silver. Six (6) of the metals are typically found in paints, ex-cluding selenium and silver.

15. TOXICITY CHARACTERISTIC LEACHATE PROCEDURE (TCLP): The

U.S. Environmental Protection Agency (USEPA) required sample preparation and analysis for determining the hazard characteristics of a waste material.

2. Antifreeze admixtures will not be allowed in the mortar. No frozen work shall be built upon. No masonry unit having a film of frost on its surface shall be laid in the work. Any completed work found to be affected by frost shall be taken down and rebuilt.

C. Lay masonry plumb; true to line; with level courses; straight, clean, uniform joints; dry surfaces; and straight, plumb corners. Maintain vertical alignment of joints as required to match existing bond patterns. Align horizontal joints with tops of openings, as indicated. Lay units in solid partitions in manner to provide same evenness of surface on each side.

D. Adjust each masonry unit in final position while mortar is still soft and plastic. Remove any unit disturbed after mortar has stiffened and re-lay with fresh mortar.

E. Provide all chases, slots, and recesses as required to accommodate the work of other trades. Close only after such work has been installed tested, and approved. As the work progresses, set all anchors, bolts sleeves, frames, lintels, and all other items of the various trades required to be built-into the masonry. No cutting and patching of completed masonry work will be permitted except as approved by The Owner's Project Manager.


F. Do not use installed masonry work to support or in any way receive scaffolding or other temporary supports.

G. Provide complete protection against breakage, staining and weather damage to masonry. Masonry, when not roofed over, shall be positively protected with non-staining waterproof coverings, properly weighted, at night, during showers, and whenever masons are not working on the structure.

H. Maintain masonry clean as the work progresses. Exercise extreme care at exposed work to prevent smearing or staining with mortar. Wash mortar stains immediately from exposed surfaces. At completion of work cut out and repoint all holes and defective joints, leaving the entire work free of blemishes.

3.02 BRICK MASONRY WORK

A. Brick shall be studied for permeability before laying. Hard impervious brick shall be laid dry to assure maximum bonding. Bricks with high rate of suction (in excess of 0.025 oz. per sq. in. per min. under ASTM C67) shall be laid moist, but free of surface moisture, to permit proper moisture retention in the mortar.

B. Salvaged Bricks shall be re-installed in their proper locations. Construct brick work to conform to approved sample panel.

C. Shove bricks into place (do not lay) in full mortar beds, with vertical and horizontal joints completely filled when laid. Do not slush. Strike exposed joints flush with face of brick, then finish to match existing. Exercise extreme care to prevent mortar from falling into cavities and from bridging across to the new internal vent spaces. Provide temporary wood or metal strips in the cavities, raised as the work is carried up, or other suitable method to prevent clogged vent holes.

D. When mortar at exposed joints has become partially set, and will make a thumbprint under pressure without displacement of mortar, the joints shall be tooled to match existing.

3.04 ADJUSTING

A. Damaged or Defective Masonry:

1. Remove and replace masonry units which are loose, chipped, broken, stained, or otherwise damage or, if units do not match adjoining units as intended.

2. Provide new units to match adjoining units and install in fresh mortar pointed to eliminate evidence of replacement.

3.05 BUILDING CLEANING

A. Clean masonry effected by lintel replacement work:


1. High pressure water wash with EnviroKlean Restoration Cleaner by Prosoco, or approved equal. Prepare sample test area to determine strength of blast.

2. Spot clean stains, efflorescence, atmospheric grime, and rust with SureKlean Heavy Duty Concrete Cleaner. Dilute as per manufacturer’s specifications.

a. Pre-wet a large area. When cleaning highly porous surfaces on hot days, a second pre-wetting is suggested. When cleaning vertical walls, keep lower areas wet to avoid streaks.

b. Apply cleaning solution freely, using a soft fibered masonry washing brush or low pressure (40 psi) spray. Allow it to remain on the wall for 1-2 minutes, depending on drying conditions. Do not allow cleaning solution to dry into the surface, because this may leave residue and stain.

c. Reapply cleaning solution and scrub or scrape surface using wood blocks or other non-metallic scraping devices. Take care not to harm the surface.

d. Rinse thoroughly with fresh water. Complete rinsing is important to assure removal of all residues from the porous masonry. High pressure rinsing equipment with pressures of 500-1500 psi at a volume of 6-10 gallons per minute will prove most effective

e. Protect windows, window frames, and window trim from damage due to cleaning chemicals and operations. Protect against water infiltration into the building due to pressure washing.

3.06 BUILDING CLEANING

A. Clean entire exterior of building exterior:

1. High pressure water wash with EnviroKlean Restoration Cleaner by Prosoco, or approved equal the entire building. Prepare sample test area to determine strength of blast.

2. Spot clean stains, efflorescence, atmospheric grime, and rust with SureKlean Heavy Duty Concrete Cleaner. Dilute as per manufacturer’s specifications.

a. Pre-wet a large area. When cleaning highly porous surfaces on hot days, a second pre-wetting is suggested. When cleaning vertical walls, keep lower areas wet to avoid streaks.

b. Apply cleaning solution freely, using a soft fibered masonry washing brush or low pressure (40 psi) spray. Allow it to remain on the wall for 1-2 minutes, depending on drying conditions. Do not allow cleaning solution to dry into the surface, because this may leave residue and stain.


c. Reapply cleaning solution and scrub or scrape surface using wood blocks or other non-metallic scraping devices. Take care not to harm the surface.

d. Rinse thoroughly with fresh water. Complete rinsing is important to assure removal of all residues from the porous masonry. High pressure rinsing equipment with pressures of 500-1500 psi at a volume of 6-10 gallons per minute will prove most effective.

3. Spot clean paints, oils, grease, and coatings with SureKlean Fast Acting Stripper by Prosoco, or approved equal.

a. Prepare the surface by thoroughly dry scraping off all peeling and loose paint.

b. Apply a thick coating of Sure Klean Fast Acting Stripper using a natural fiber cleaning brush, roller or large paint brush.

c. Allow stripper to dwell on the surface for 15-30 minutes or until coating “lifts” or shows indications of dissolving. Periodic agitation with a stiff bristle bush will improve stripper penetration. Take precautions to prevent passerby from coming near treated surfaces.

NOTE: Stripper should not be allowed to dry on the surface - stripping results may be unsatisfactory. If tests indicate long waiting periods will be necessary, reapply the stripper to prevent the previously applied material from drying.

d. Remove stripper and residue using pressure rinsing equipment (400-600 psi) or garden hose with adjustable water nozzle. Adjust the nozzle to provide a concentrated stream of water and flush the stripper and residue thoroughly from the surface. Heated water (150-180F) may improve stripping efficiency.

NOTE: Coatings that have been on the surface for a number of years will react differently when chemically stripped. Often, removing paints will require multiple applications and increased “dwell” time before complete removal.

e. Follow by thoroughly cleaning with EnviroKlean Restoration Cleaner according to product instructions.

4. Apply clear breathable masonry sealer to 100% of the exterior masonry. All proposed waterproofing materials shall comply with the latest edition of the Massachusetts Architectural Industrial Maintenance VOC Rule. Provide evidence of compliance with VOC Rule from Manufacturer. Clear sealers may be by the following manufacturers or approved equal:

a) BASF - Hydrozo Clear 40 VOC b) Conproco – Shield MX c) Prosoco – SureKlean Weather Seal H40


The sealer shall be compatible to the façade joint sealant material. Protect all existing surfaces during installation. Provide a 10-year Warranty from the manufacturer on the clear sealer. Install as per the manufacturer’s recommendations.
