15、ards concerning insulation materials or accesso-ries. (See Appendix X2 for sources of information.)4.3 This classification recognizes that proper handling andinstallation procedures can substantially reduce the potentialconcerns and effects. Further, it recognizes that in somesituations the presence
16、 or creation of potential effects orhazards results from an intervening act of human or naturalorigin, or depends on access to or contact with the materials oraccessories. Lack of compatibility of the individual compo-nents of an insulation system with each other or the environ-mental conditions wit
17、hin which the system will operate, orboth, may create unanticipated effects. (See Appendix X3.)5. Basis of Classification5.1 Classification is based on several broad groupings ofpotential concerns that could result from direct contact withthermal insulation materials and accessories, or be caused by
18、indirect actions or events.5.2 Potentials that occur from direct contact or indirectaction or events are described as follows:5.2.1 Potential Health EffectsThose effects that create riskof temporary or permanent changes in normal body functionsand biochemical activity. The latter may involve vapors
19、(suchas organic solvent fumes), corrosive liquids (acids, alkalies,and organics), and solids (usually high surface area particu-lates) that react with body tissues or fluids.5.2.1.1 AMaterial Safety Data Sheet (MSDS) is required bythe Occupational Safety and Health Administration (OSHA),U.S. Departm
20、ent of Labor (29CFR 1910.1200) for hazardouschemicals produced in the United States, or imported. (TheMSDS for any product or material is issued and available fromthe organization producing the product or material.)5.2.1.2 The MSDS for any insulation product, system, oraccessory (including adhesives
21、) should be obtained and re-viewed to determine any potential effect on humans using orinstalling the material.5.2.1.3 When tests are included in a standard, the MSDS forchemicals required ahould be reviewed to ensure that properguidance for safe handling and use is incorporated.5.2.2 Potential Trau
22、matic Injury Effects (Table 1)Theseeffects may result from sharp or rough materials or accessorieswhich have protrusions or abrasive surfaces, causeoverheating, or transmit electrical energy, and generally requiredirect contact with the material or accessory causinglacerations, abrasions, punctures,
23、 etc.5.2.3 Potential Effects Resulting from Combustion (Table2) Those effects that result principally from the emission ofheat, gases (toxic and non-toxic), fibers, particulates, anddepletion of oxygen which takes place during combustion thatexposes or involves insulation materials or accessories.5.
24、2.4 Potential Effects from Structural Conditions (Table3)Those effects that result principally from the overloadingor deterioration of structural members of a building resulting infailure of the structure, or a portion of it, and its collapse onoccupants.TABLE 1 Potential Traumatic InjuryInsulation

COMMENTARYX1.1 Background of StandardThe original concept wasto develop two standards that alert task groups writing stan-dards to safety and health concerns associated with thermalinsulation materials and accessories during installation andafter in
31、stallation. Classification C930 80 resulted from anumber of drafts and concerned the effects during installation.X1.1.1 Subsequently attention was given to the effects afterinstallation and a proposed classification standard proceededthrough a number of drafts, with several new approaches to theclas
32、sification and information presented. Finally it was agreedthere was sufficient similarity between the existing standard(Classification C930 80) and the proposed, so that theyshould be combined into one standard (Oct. 1982 Subcommit-tee meeting).X1.1.2 This revision combines the concerns and effects
33、associated with thermal insulation materials and accessoriesduring installation, and (after) when remodeling, or retrofitting,or as a result of indirect action or events.X1.1.3 This is a resource document intended solely to alertstandards writers and users of insulating materials and acces-sories to
34、 potentials. It is most emphatically not an evaluation ofcomparative risks, nor is it a predictor of inevitable problems.No effort has been made to address the numerous preventive orremedial measures available to manufacturers and users, eventhough it is recognized that many of these are routinely u
35、sed.The user in a corporate sense has a responsibility to advise theinstaller (tradesman), as an employee, of the informationsupplied by the manufacturer.X1.1.4 During deliberations on the revision of C930 80,many requests to add qualifying or explanatory phrases andfootnotes that indicate increased
36、 or decreased potential riskwith specific products were received. It became clear that thisqualifying or explanatory information would move the classi-fication into territory beyond its own scope by noting palliativemeasures and assigning degrees of risk to some products andTABLE 2 Potential Effects

43、ative, non-quantitative listsof potential hazards to be used by standards writers,manufacturers, and users who are responsible for taking thepotentials into account. Thus they are no more, no less, thanchecklists.X1.1.6 Since adoption of Classification C930 85, anOSHA (Occupational Safety and Health
44、 Administration, U.S.Department of Labor) Regulation on Hazard Communication29CFR 1910.1200 has been implemented. The use and avail-ability of Material Safety Data Sheets (MSDSs) has becomewidespread. MSDSs are more comprehensive and up-to datethan Table 1 in Classification C930 85. Therefore, Table
45、 1has been deleted. Standards writers and users should refer toMSDSs and applicable federal, state, and local laws andregulations for potential health effects.X1.2 Summary of Changes in Classification C930 85:X1.2.1 Descriptions of Terms Specific to This StandardThis section replaced the former Sect
46、ion 2 on Definitions. Allof the terms were new and relate to terms used.X1.2.2 Significance and UseThis section was new. Itfocuses on identification of the potential concerns and effectsthat may occur during the life cycle (installation, service,removal, and disposal) of insulation materials and acc
47、essories,and points out that remedial or preventative steps are notidentified.X1.2.3 Basis of ClassificationThis section replaced theprevious 4, “General Types of Hazard” of Classification C93080. It reflects a new approach to the grouping and identificationof potentials. All sections are concerned
48、with potentials thatmay occur during and after installation.X1.2.4 Table 1, Potential Health EffectsThe terminologyof products, etc., were upgraded and the quantifiers wereremoved from “potential effects on humans.”X1.2.5 Table 2, Potential for Traumatic InjuryThis tablereplaced the former Table 2,
49、“Mechanical Safety Hazards,” andprincipally covers electric shock potentials.X1.2.6 Table 3, Potential Effects Resulting fromCombustionThis table reflects the intent of the previousTable 3.X1.2.7 Table 4, Potential Effects Resulting from StructuralConditionsThis new category recognizes that there may bean effect from moisture on certain structural components, orfrom uncontemplated additional weight load of added insulat-ing materials.
