18、iscussionA large building space is defined as onewhose minimum dimension exceeds two feet.3.2.6 ownerthe person, partnership, corporation, agency,or other entity who owns the building in which the IRCCS isto be applied whether such ownership is by virtue of deed,contract, or any other instrument for

19、 acquiring legal title underthe laws of the state in which the building is located.4. 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

20、of an IRCCS will reduce 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

21、 of electrical wiring 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.4.4 This pr

22、actice presents requirements that are general innature and considered practical. They are not intended asspecific recommendations. Consult the manufacturer for rec-ommended application methods.5. Safety Precautions5.1 The applicator shall wear proper clothing and equipmentas recommended by the manuf

23、acturer and shall follow localcodes and safety regulations for building construction sites.(For example, hard hats, safety goggles, and respiratory pro-tection will be required, depending on site conditions.)5.2 Ventilation shall be provided to insure that mist andoverspray are immediately dispersed

24、 from the application area.If natural ventilation is not adequate, place OSHA approvedfans may be placed in windows or doors adjacent to theapplication area to improve ventilation.5.3 Manufacturers instructions shall be consulted for allapplicable handling and safety recommendations.6. Pre-Installat

25、ion 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,rotting, or other structural damage. Do not apply IRCCS insuch areas until t

26、he 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. Ifthere is reason to believe the electrical system is faulty, do notapply t

27、he 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 deficiencies: lights dimming, fusesblowing, circuit breakers tripping frequently,

28、 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 areas where an IRCCS is to be applied, theapplicator shall locate and plan the

29、application around venti-lation openings. The applicator shall not apply the IRCCS in away that will plug or otherwise obstruct existing ventilationopenings.6.2 Preparations:6.2.1 All electrical wiring at or near the IRCCS applicationsurfaces shall be protected to ensure that the IRCCS materialcanno
