The requirements for testing laboratory qualifications and product sampling, as well as the specific material and test standards and editions used in this evaluation, are as set forth in the applicable documentation noted in Section 6.0 of the master evaluation report. 3.0 DEFINITIONS The following definitions are from the Definitions and Testing Requirements for Residential Insulation, Version 1.0, and are applicable to the subject of this report. 3.1 General Definitions Insulation: Any material mainly used to slow down heat flow. It may be mineral or organic, fibrous, cellular, or reflective (aluminum foil). It may be in rigid, semi-rigid, flexible, or loose-fill form. Residential Buildings: Single family homes (attached or unattached), multifamily buildings with 4 units or fewer, or multifamily buildings (condominiums, apartments) with 3 stories or less in height above grade. 3.2 Insulation Product Definition Spray or Pour Foam Insulation: A thermal insulating material that is sprayed or poured (as a gel or foamy liquid) into place, ESR-2642 Supplement | Most Widely Accepted and Trusted Page 2 of 9 and expands or sets into a cellular foam and cures at the point of installation through a chemical reaction. Foamed materials include, but are not limited to, polyurethane, polyisocyanurate, phenolic and cementitious insulation. 3.3 Insulation Performance Definitions R-value: The inverse of the time rate of heat flow through a body from one of its bounding surfaces to the other surface for a unit temperature difference between the two surfaces, under steady state conditions, per unit area. For the purposes of the Seal and Insulate with ENERGY STAR program, only Imperial units will be accepted [(h·ft2·°F)/Btu]. Smoke-Development Index: The characteristic of a material to emit smoke when exposed to flame or fire compared to red oak and inorganic cement. Flame-Spread Index: The characteristic of a material to resist the spreading of flames when exposed to flame or fire compared to red oak and inorganic cement. 3.4 Thermal Resistance: The SPRAYTITE®, COMFORT FOAM® and WALLTITE® spray-applied foam plastic insulations have thermal resistance R-values as noted in Table 1 of ESR-2642, based upon testing. 3.5 Installation 3.5.1 General: The installation of the SPRAYTITE®, COMFORT FOAM® and WALLTITE® spray-applied foam plastic insulations must be in accordance with the requirements set forth in Sections 4.0 and 5.0 (as applicable) of ESR-2642. The insulation is manufactured on-site by spray polyurethane foam applicators meeting the qualification requirements stated in Section 5.5 of ESR-2642. The insulation should not be installed in direct contact with chimneys, flues or heat-producing appliances. See Figure 7 for recommended clearances. 3.5.2 Personal Protective Equipment (PPE): The following personal protective equipment (PPE) requirements are reprinted from the website of the American Chemistry Council (ACC) and deal with Spray Polyurethane Foam Health and Safety (http://www.spraypolyurethane.org/PPE): “PPE for SPF High Pressure Interior Application: When spraying an SPF two-component high pressure spray polyurethane foam system indoors, sprayers and helpers should wear:  A NIOSH-approved full face or hood-type supplied air respirator (SAR) (as outlined in your company's Respiratory Protection Program)  MDI-resistant chemical gloves (e.g., nitrile), or fabric gloves coated in nitrile, neoprene, butyl, or PVC  Chemically resistant long-sleeve coveralls or chemically resistant full body suit with hood  MDI-resistant fitted boots/booties” “Protective Clothing: The use of appropriate protective clothing is necessary whenever there is possibility of direct contact with SPF chemicals. The appropriate protective clothing varies depending upon the potential for exposure. Applicators and helpers typically wear disposable coveralls to keep spray and mist from contacting skin and clothing. To protect skin, wear PPE in such a manner as to protect all skin (in other words, there should be no exposed skin showing). When not wearing a hood respirator, select a coverall with an attached hood or spray head cover. For tasks where there is a potential for splash, consider a suit coated with an impermeable coating such as PVC and MDI-resistant fitted boots/booties.” “Gloves: Gloves made of nitrile, neoprene, butyl or PVC generally provide adequate protection against A-side materials. (See Guidance for the Selection of Protective Clothing for MDI Users, Center for the Polyurethane Industry (CPI) Guidance Document AX178). A-side protection is generally considered adequate to provide B-side protection; however, consult the manufacturer’s SDS for specific information about B-side protection.” “Eye and Face Protection: Appropriate eye protection helps prevent eye contact from splashes of liquid SPF chemicals, accidental sprays of reacting foam, aerosols and vapors that are likely to be present during spraying, and airborne particulate associated with sanding and grinding operations. The type of eye protection needed depends on the nature of the activity.” Persons handling liquid SPF chemicals in open containers can protect their eyes by wearing safety goggles or safety goggles in combination with face shields. The use of contact lenses is discouraged. During application of SPF, eye protection may be provided by virtue of wearing a full-face or hood respirator. OSHA requires that an eyewash* or safety shower be provided in the work area where the eyes or body may be exposed to “injurious corrosive materials.” Consult the SDS for all materials to be used on the job in advance to help you understand whether such materials will be present, and if so, how to comply with applicable OSHA requirements. “Respiratory Protection: Engineering controls, such as local exhaust ventilation, can be used to control SPF chemical exposures. Administrative controls, such as work schedules and work practices, are used concurrently to minimize exposure. Respirators are needed when air concentrations continue to exceed occupational exposure limits when engineering and administrative controls are implemented. These limits have been set for a number of SPF chemicals and some common chemicals encountered during SPF application. ESR-2642 Supplement | Most Widely Accepted and Trusted Page 3 of 9 Air-purifying respirators (APR) and powered air-purifying respirators (PAPR) are generally appropriate for exterior applications and may be used when spraying polyurethane foam in exterior applications. Supplied air respirators (SAR) are typically used in interior applications. Refer to the NIOSH Respirator Decision Logic (2004) for more information regarding respirator selection.” Ventilation of the work area is required and should be in accordance with Ventilation Considerations or Spray Polyurethane Foam: Guidance on Ventilation During Installation of Interior Applications of High-Pressure Spray Polyurethane Foam as published by the Spray Foam Coalition (SFC) of the Center for the Polyurethanes Industry (CPI). The following statement regarding ventilation of the work area is reprinted from the guidance document: “Work zone mechanical ventilation during and after SPF installation is designed to prevent workers and others in the area from being exposed to SPF chemicals above recommended or permissible levels. Potential health effects from exposure above recommended levels can range from no effects to slight irritation of the eyes, skin or respiratory system to the development of chronic lung or pulmonary disease depending on the individual person and level and duration of overexposure.” 3.5.3 Occupancy Time after Installation: The re-entry or re-occupancy time shall be in accordance with the manufacturer's installation instructions, which are reprinted on pages 4 and 5 of this certification. 3.5.4 Figures: Figures 1 through 6 represent general installations of the SPRAYTITE®, COMFORT FOAM® and WALLTITE® spray-applied foam plastic insulations in vented and unvented crawl spaces, the interior of below-grade foundation walls, the exterior of above-grade walls, and in vented and unvented attics.

This supplement expires concurrently with the master report reissued February 2015. ESR-2642 Supplement | Most Widely Accepted and Trusted Page 4 of 9 BASF Re-Occupancy Times for Interior Building Spray Applications Jim Andersen, Marketing Applications Specialist SR 021514 Introduction The application of spray foam insulation is done through special high pressure spray application equipment, Low pressure application units or single component foams. This document will discuss two part foams field process using high pressure application equipment. When the combination of liquid part A compound and liquid B compound is done to produce either closed cell or open cell spray foam insulation there are potential health hazards during the application. OSHA and other government agencies have established protection requirements for all workers that can be exposed to the chemicals during the spray application. Only trained and properly protected workers are allowed in the spray application areas during the spraying and for a period after the spraying has stopped. Requirements The spray area should be posted with keep out WARNING signs before and after spraying. Workers only that are trained and have the necessary personal protection equipment are allowed inside the spray area. All others must be kept out as well as pets. Ventilation of the spray area is to be done incorporating the guidance documents: “Ventilation Guidance for Spray Polyurethane Foam Application,” published by the U.S. Environmental Protection Agency (EPA), online at www.epa.gov/dfe/pubs/projects/spf/ventilation-guidance.html and “Good Practices – Engineering Controls and Ventilation,” published by the American Chemistry Council’s Center for the Polyurethanes Industry, available online at: www.spraypolyurethane.org/GoodPractices#EngineeringControls The following general requirements must also be followed, Code of Federal Regulations Title 29 CFR §1926.20 Safety and Health Regulations for Construction: General Safety and Health Provisions available online at www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=STANDARDS&p_id=10606 The applicators and building owners should visit www.spraypolyurethane.org and also www.spf.basf.com for up to date information about spray polyurethane foam construction applications before starting projects. Industry Established Re Occupancy Times The Spray Foam Industry and government agencies have worked together to establish general guidelines for re occupancy. These can be found at www.spraypolyurethane.org. The general statement of 24 hours for re occupancy times for interior building applications is the general rule BASF suggests for two part high pressure spray. “Evaluation reports for many types of building products, including SPF insulation, often include the suggested reoccupancy time, which is variable: for an interior application using two-component high-pressure SPF, some manufacturers recommend 24 hours before reoccupancy, and for an interior two-component, low-pressure SPF kit application, some manufacturers recommend a one hour reoccupancy time. Consult the product manufacturer to determine the recommended reoccupancy time for the particular job and SPF in use. Note: ”Exterior applications where the spray application is done to a roof top application or exterior walls and where there is wide open air spaces; the risk control is done by closing off all air intake areas to a building interior,(windows, doors, warning signs and HVAC intake vents). Roof or exterior applications will generally have plenty of ventilation with natural wind as well as massive volumes of space to dissipate the concentration of materials. Therefore the controls used for interior applications are not generally required, such as added ventilation. The elastomeric roof coatings vary in risks and must be assessed and the risks evaluated on a job by job and material specific basis by the spray foam applicator company. BASF Re occupancy Research BASF, Air Products and Honeywell have conducted proprietary studies for indoor air quality measurements on spray foam applications to retrofit attics. Robert, William, James Andersen, Richard Wood, and Mary Bogdan. “Ventilation and Re-Occupancy of a Residential Home Sprayed with High Pressure Polyurethane Foam.” Presented at the CPI Technical Conference, September 2012 ESR-2642 Supplement | Most Widely Accepted and Trusted Page 5 of 9 This study of three houses where the attic was sealed and ventilated during the spray application has resulted in no chemicals detected within the house at levels greater than those currently assigned levels by government agencies and private chemical manufactures’ Material Safety Data Sheets (MSDS) or Safety Data Sheets (SDS). This particular application process indicates 2 hours after spraying has stopped and ventilation continued that re- occupancy can occur within the homes. The spray foam was done above the sheetrock in non inhabited attic spaces. BASF continues field monitoring testing as well as supports continued research being done by the American Chemistry Council/Center for the Polyurethane Industries of which we are an active member. Summary This information has been provided for use by our spray foam applicators and distributors use. It may also be used to inform end customers who have contracted to have spray foam produced by spray foam applicators to their buildings. It is offered in good faith and believed to present the risks and best industry practices to manage them. Since each field application is different the responsibility rests with spray foam applicators to assess the job risks and control them per the OSHA and others requirements.
