Significance and Use4.1 This practice recognizes that effectiveness, safety, anddurability of an IRCCS depends not only on the quality of thematerials, but also on the proper installation.4.2 Improper installation of an IRCCS will redu
20、ce itsthermal effectiveness, cause fire risks and other unsafe condi-tions, and promote deterioration of the structure in which it isinstalled. Specific hazards that can result from improperinstallation include: heat buildup in recessed lighting fixtures,deterioration of failure of electrical wiring
21、 components, anddeterioration of wood structures and paint failure due tomoisture accumulation.4.3 This practice provides recommendations for the instal-lation of IRCCS materials in a safe and effective manner.Actual conditions in existing buildings will vary greatly.Insome cases additional care sho
22、uld be taken to ensure safe andeffective installation.4.4 This practice presents requirements that are general innature and considered practical. They are not intended asspecific recommendations. The user should consult the manu-facturer for recommended application methods.5. Safety Precautions5.1 T
23、he applicator shall wear proper clothing and equipmentas recommended by the manufacturer and shall follow localcodes and safety regulations for building construction sites.(For example, hard hats, safety goggles, and respiratory pro-tection may be required, depending on site conditions.)5.2 Ventilat
24、ion should be provided to insure that mist andoverspray are immediately dispersed from the application area.If natural ventilation is not adequate, OSHA approved fansmay be placed in windows or doors adjacent to the applicationarea to improve ventilation.5.3 Manufacturers instructions shall be consu
25、lted for allapplicable handling and safety recommendations.6. Pre-Installation Inspection and Preparation6.1 Inspections:6.1.1 Inspect the roof, walls, ceilings, and floors to identifyareas where previous or existing moisture problems havecaused paint peeling, warpage, stain, visible fungus growth,r
26、otting, or other structural damage. Do not apply IRCCS insuch areas until the owner has been informed and has certifiedthese conditions have been corrected and their source(s)eliminated.6.1.2 In areas where the IRCCS is to be applied, compo-nents of the electrical system shall be in good condition.
27、Ifthere is reason to believe the electrical system is faulty, do notapply the IRCCS in such areas until the owner has beeninformed and qualified inspection and repair have been per-formed.NOTE 1The CPSC Product Safety Fact Sheet No. 18 has identified thefollowing signs of potential electrical defici
28、encies: lights dimming, fusesblowing, circuit breakers tripping frequently, electrical sparks and glowingfrom receptacles, light flickering, and cover plates on switches and outletsthat are warm or hot to the touch. Useful safety information is alsocontained in the NFPA 54 and NFPA 211.6.1.3 In area
29、s where an IRCCS is to be applied, theapplicator shall locate and plan the application around venti-lation openings. The applicator shall not apply the IRCCS in away that may plug or otherwise obstruct existing ventilationopenings.6.2 Preparations:6.2.1 All electrical wiring at or near the IRCCS app
30、licationsurfaces shall be protected to ensure that the IRCCS materialcannot contact the electrical wiring system.6.2.2 Where attic ventilation is compromised by the instal-lation of an IRCCS or the subsequent application of fibrousinsulation, vent baffles shall be installed at the soffits of theatti
31、c such that attic ventilation airflows are maintained inaccordance with applicable building codes.6.2.3 All materials shall be mixed for at least 2 minimmediately before spraying. Manufacturers instructions shallbe consulted for type of mixing equipment and mixing methodsto be employed. If material
32、is to be sprayed from a pressurepot, the pot shall be equipped with an air driven agitator.NOTE 1Apply IRCCS to cover the exposed roof deck area. Thelow-emittance surface of the IRCCS must face the interior of the attic.FIG. 1 Typical Residential UseNOTE 1Apply the IRCCS to cover the entire interior
33、 surface area. Thelow-emittance surface of the IRCCS must face the interior of the bldg.FIG. 2 Typical Industrial, Commercial, and Agricultural UseC13210427.
