Grounded electrical connec-tions shall be used.10.1.2 Protective EquipmentAll persons in the applica-tion area shall wear protective equipment as required. Ex-amples of equipment that may be

23、needed are: respirators, dustmasks, coveralls, goggles or safety glasses, and hard hats.10.1.3 Workmen shall not wear loose fitting clothing thatcould become caught in the machinery. However, that person-nel actually spraying product may wear loose, long sleeveclothing for protection and comfort rea

24、sons.10.1.4 ScaffoldWhen required, a strong, lightweight,stable, rolling scaffold shall be used. An open grate flooringwill help prevent material build up on the scaffold floor. Safetyrailing meeting OSHA regulations shall surround the scaffoldfloor area.10.1.5 FloorsThe floors in the work area shal

25、l be keptfree of obstructions, excessive moisture, waste material, orother unsafe conditions.11. Substrate Preparation11.1 Prior to the application of SFRM, all areas to besprayed shall be inspected by the applicator to ensure a suitablesurface for proper SFRM bonding. The following recommen-dations

26、 shall be followed:11.1.1 All surfaces to be sprayed shall be free of dirt, grease,oil, mill scale, loose scale, loose rust, or any material that willimpair proper adhesion.11.1.2 CleaningThe applicator shall bring to the generalcontractors attention any surface that does not meet therequirements of

27、 11.1.1. Responsibility for cleaning substratesshall be established prior to submittal of SFRM bid. Unaccept-able surfaces shall be cleaned in accordance with substrate orSFRM manufacturers recommendations. (On asbestos removalprojects it is necessary to coordinate substrate conditions andcleaning p

28、rocedures to ensure the integrity of the post removalencapsulant coatings.)11.1.3 MaskingSurfaces that are susceptible to damageand are not to be sprayed shall be masked, covered orotherwise protected from the overspray of SFRM.11.1.4 Painted SurfacesSFRM manufacturers generallydo not recommend appl

29、ication to painted surfaces. If it hasbeen established that a paint or primer is necessary, the primedsubstrate sprayed with SFRM shall be tested in accordancewith Test Methods E119.11.1.5 Post removal encapsulated surfaces (lockdown coat-ings) shall be inspected in accordance with Practice E 1368.I

30、fit has been established that a lockdown coating is necessary,the coated substrate sprayed with the SFRM shall be tested inaccordance with Test Methods E119.11.1.6 Where UL fire resistance rating designs are utilized,unless specifically prohibited in a design, SFRM may beapplied to primed or painted

Theaverage minimum bond strength values shall be determinedbased upon a minimum of five bond tests conducted inaccordance with Test Method E 736.12. Application Environment12.1 General:12.1.1 A minimum ambient and subst

35、rate temperature of4.4C (40F) shall be maintained for 24 h before, during, anda minimum of 24 h after the application of the SFRM unlessotherwise recommended by the material manufacturer. Ifnecessary for job progress, enclosures and heat shall beprovided to maintain temperatures.12.1.2 In most insta

36、nces, natural ventilation is sufficient. Inenclosed areas, forced ventilation shall be introduced forcuring.13. Application13.1 GeneralSFRM shall be applied by an experiencedfirm. The firm shall be licensed or otherwise approved to applythe SFRM.13.1.1 Equipment, mixing, and application shall be in

37、ac-cordance with SFRM manufacturers written specifications andapplication instructions.13.1.2 Application shall not start until SFRM applicatorinspects the substrates to receive protection and they are foundacceptable.13.1.3 Work shall be coordinated with other trades so thatproject progress is not

38、delayed. Application of SFRM shall becompleted prior to the installation of duct work, piping,conduit, and other suspended items. Hangers for these itemsmay be installed prior to SFRM application, thus reducingsubsequent SFRM damage.13.1.4 SFRM shall be applied after all roof construction,installati

39、on of roof-top HVAC equipment and other relatedwork is completed.13.1.5 Bonding adhesive or other surface preparation shallbe used when required and as recommended by SFRMmanufacturer.13.1.6 No SFRM shall be applied to steel deck prior tocompletion of concrete work on steel deck.13.1.7 Surface seale

40、rs are optional. When used, the surfacesealer shall be as recommended by the SFRM manufacturerand shall be applied in accordance with the SFRM manufac-turers written application instructions.14. Protection During Curing14.1 SFRM are susceptible to damage while they are curing.Precautions shall be ta

41、ken to allow the materials to curewithout physical abuse.14.1.1 Heating and ventilation shall be provided whenneeded for curing (see 12.1).14.1.2 No roof traffic shall be allowed during application orduring the curing period of the SFRM applied to the roof.(WarningRoof traffic at any time after the

42、SFRM is fullycured shall be avoided if possible. Excessive traffic, loading orimpact, can cause SFRM delamination.)14.1.3 Care shall be taken so that deflection or impactgreater than the SFRM manufacturers recommended limits donot occur. The maximum allowable steel deck deflection shallbe determined

43、 in accordance with Test Method E 759 and theeffects of impact shall be determined in accordance with TestMethod E 760.15. Inspection Procedures15.1 An independent testing laboratory shall inspect theapplied SFRM upon the completion of each floor for thicknessand density in accordance with Test Meth

44、ods E 605.15.2 Results of thickness and density testing shall be madeavailable to the SFRM applicator before application progressesmore than two floors beyond the floor in question.15.3 Where required by contract documents or buildingcode authority, the SFRM shall be tested upon curing forcohesion/a

45、dhesion in accordance with Test Method E 736 byan independent testing laboratory.15.4 Results of cohesion/adhesion testing shall be madeavailable to the SFRM applicator as soon as practical. Depend-ing upon job scheduling and jobsite conditions, it may not bepossible to conduct cohesion/adhesion tes

46、ts in a timely manner.16. Patching16.1 PatchingIn areas where the SFRM has been re-moved, it shall be resprayed or patched with the same materialor with a compatible material as determined by a fire test.16.2 Patching shall be done by the SFRM applicator.Responsibility for payment of patching shall

47、be decided priorto bid submittal.17. Clean up17.1 Upon completion of the application, the work areashall be cleaned.17.1.1 EquipmentAll equipment shall be removed fromthe site.17.1.2 FloorsAll floors shall be swept clean.17.1.3 MiscellaneousAll waste materials such as polyeth-ylene, floor sweepings,

48、 or trash bags shall be removed from thework area and disposed of in an appropriate manner.18.
