4.1088.9a
All worker safety specifications will be in accordance with SWS 2.0100.3 Worker Safety
Ensure worker safety, especially in regard to fall protection considerations and contaminants found in demolition, such as asbestos, lead, polychlorinated biphenyls, etc.
4.1088.9c
Conduct pre-inspection in accordance with SWS 2.0100.4 Work Area Inspection and Stabilization
Gaps, cracks, and holes in fire separations located within the work area will be visually identified and incorporated into air sealing work scope, including those that span two conditioned or unconditioned spaces
Where drawings are available that identify specific fire-resistance ratings (i.e., 1 hour, 2 hour), materials and methods will be employed to preserve or restore such rating
Where drawings are unavailable or do not identify specific fire-resistance ratings, the fire-resistance rating of the assembly may be inferred from the current construction (i.e., single 5/8 sheetrock, concrete masonry unit), and materials and methods employed will be consistent with restoring or preserving such inferred fire-resistance rating
Repairs necessary to stabilize work areas and protect or preserve integrity of energy improvement will be completed before subject work begins
Insulation will not be installed if moisture-related issues are not resolved
Ensure and preserve the integrity of fire separations
Ensure a durable, continuous air and
thermal boundary
Thermal boundary
The separation between the interior and exterior environments of a building that slows heat flow
4.1088.9d
Sealants will be compatible with their intended surfaces and applied in accordance with manufacturer specifications
Selection will be durable, pest resistant, and have a weather-appropriate seal
Indoor sealants will be low volatile organic compound (
VOC
VOC
Volatile organic compound
) products that meet independent testing and verification protocols, such as Green Seal GS-36, "GREENGUARD Children and Schools," or comparable certifications
Fire-resistance rated assemblies will be provided with sealants permitted by the authority having jurisdiction and adopted building code
Prevent intrusion of moisture and pests into the sealed assembly
Prevent exposing workers or occupants to excessive
VOC
VOC
Volatile organic compound
levels
Ensure sealant meets or exceeds the performance characteristics of the assembly and is compliant with local fire code requirements
4.1088.9e
When tenting is required, an airtight, rigid, and insulated enclosure will be installed around entire sprinkler system exposed within the attic
Enclosure will be sealed to the existing attic
air barrier
Air barrier
The separation between the interior and exterior environments of a building that slows air flow to the point that no smoke movement is visible at 50 pascals of pressure difference across the boundary
Fire-rated materials will be used when applicable
Insulation will be installed on top of enclosure to the same R-value as the rest of the attic or rigid insulated enclosure will have an equivalent R-value as the rest of the attic
Align insulation and
air barrier
Air barrier
The separation between the interior and exterior environments of a building that slows air flow to the point that no smoke movement is visible at 50 pascals of pressure difference across the boundary
Create insulated enclosure that prevents sprinkler system from freezing
