Materials that have gone beyond their shelf life shall beremoved from the job site, or manufacturer shall providedocumentation attesting that the product is still usable for itsoriginal i
17、ntended purpose.7.3 Materials shall be kept dry until used and stored off theground under cover.8. Equipment and Utilities8.1 Equipment used for application shall be of a typerecommended by the SFRM manufacturer. Equipment shallinclude, but is not limited to: application machine, materialmixer, mate

19、ing (see 12.1.1), and8.3.2 Forced ventilation (see 12.1.2).9. Fire Resistance Classifications9.1 GeneralRequired fire resistance classifications areoutlined by building codes such as those published by BOCA,3SBCCI,4ICBO5and enforced by local authorities havingjurisdiction. Required fire resistance c
20、lassifications are deter-mined by construction type, occupancy, and location.9.2 Architects and material specifiers shall indicate onconstruction drawings and in specifications the required fireresistance classification(s) for a project. They shall also indi-cate what elements of that project are to
21、 be so protected. (SeeNote 1.)NOTE 1The architect and material specifier may indicate on construc-tion drawings and in specifications a reference number for a fire resistancesystem capable of providing the required protection.10. Safety10.1 Current OSHA, applicable local ordinances, or coderegulatio
22、ns shall be followed at all times.10.1.1 Equipment shall have safety guards that meet appli-cable OSHA regulations in place. 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 equipm
23、ent that may be 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
24、 and comfort reasons.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 th
25、e work area shall 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
26、recommen-dations 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 th
27、erequirements of 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 conditio
28、ns andcleaning procedures 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 no
29、t recommend application 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 P
30、ractice E1368.Ifit 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 pr

32、nimum average bond strength of 80 %and a minimum individual bond strength of 50 % whencompared to the bond strength of the fire resistive coating asapplied to clean uncoated18 in. (3.2 mm) thick steel plate. Theaverage minimum bond strength values shall be determinedbased upon a minimum of five bond

Application Environment12.1 General:12.1.1 A minimum ambient and substrate 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 p
36、rogress, enclosures and heat shall beprovided to maintain temperatures.12.1.2 In most instances, 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
37、 otherwise approved to applythe SFRM.13.1.1 Equipment, mixing, and application shall be in 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 foundac
38、ceptable.13.1.3 Work shall be coordinated with other trades so thatproject progress is not 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 reducin
39、gsubsequent SFRM damage.13.1.4 SFRM shall be applied after all roof construction,installation 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 a
40、pplied to steel deck prior tocompletion of concrete work on steel deck.13.1.7 Surface sealers 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 Dur
41、ing Curing14.1 SFRM are susceptible to damage while they are curing.Precautions shall be taken 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 th
42、e curing period of the SFRM applied to the roof.(WarningRoof traffic at any time after the 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 rec
43、ommended limits donot occur. The maximum allowable steel deck deflection shallbe determined in accordance with Test Method E759 and theeffects of impact shall be determined in accordance with TestMethod E760.15. Inspection Procedures15.1 An independent testing laboratory shall inspect theapplied SFR
44、M upon the completion of each floor for thicknessand density in accordance with Test Methods E605.15.2 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
45、 documents or buildingcode authority, the SFRM shall be tested upon curing forcohesion/adhesion in accordance with Test Method E736 by anindependent testing laboratory.15.4 Results of cohesion/adhesion testing shall be madeavailable to the SFRM applicator as soon as practical. Depend-ing upon job sc
46、heduling and jobsite conditions, it may not bepossible to conduct cohesion/adhesion tests 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 Patc
47、hing shall be done by the SFRM applicator.Responsibility for payment of patching shall 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 swep
