1、Designation: C 930 05Standard Classification ofPotential Health and Safety Concerns Associated WithThermal Insulation Materials and Accessories1This standard is issued under the fixed designation C 930; the number immediately following the designation indicates the year oforiginal adoption or, in th
2、e case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This
3、 classification identifies potential concerns and ef-fects that could result from direct contact with thermal insula-tion materials and accessories, or be caused by indirect actionof events such as aging, fire, or physical disturbance.1.2 Intent of Classification:1.2.1 It is the intent of this class
4、ification to alert others topotential concerns, effects, hazards, or risk.1.2.2 It is not the intent of this classification to establish thedegree of risk or hazard or limiting values of potential hazards.1.2.3 It is not the intent of this classification to establish orrecommend methods or markings
5、to reduce or mitigate thepotential; however, it is recognized that correct procedures andprecautionary measures can substantially reduce or eliminatesome of the potential concerns, effects, hazards, or risks.NOTE 1See Appendix X1 for commentary.1.3 This classification recognizes the responsibility o
6、f pro-ducers and users, as appropriate, to: (1) provide information onknown effects or hazards, (2) advise on established safety andhealth practices, and (3) determine applicable regulatory re-quirements.1.4 This classification does not address the health and safetyconcerns of thermal insulation mat
7、erials and accessories duringmanufacture.1.5 Omission of an item from this classification does notimply an absence of potential concerns or effects.1.6 There is no importance in the order of listing.2. Terminology2.1 Definitions of Terms Specific to This Standard:2.1.1 degree of riskthe probability

9、lth potential.2.1.4 indirect action or eventsthe actions or events thatare not directly created by, or straightforwardly caused by, theperson(s) potentially exposed to the effects or hazards.2.1.5 potentialthe possible as opposed to the actual; thatwhich may, but has not yet, come into being; that w
10、hich islatent, unrealized.2.1.6 riskthe exposure to chance of injury or illness orloss.3. Significance and Use3.1 The purpose of this classification is to identify potentialconcerns and effects which may occur during the life cycle(installation, service, removal, and disposal) of insulationmaterials
11、 and accessories resulting from direct contact orindirect action or events.3.2 This classification does not identify remedial or preven-tive steps that may be taken to correct potential problems orhazards; rather it is intended as a checklist that will make iteasier to deal constructively with these
12、 potentials, and todetermine what, if any, specific requirements need to be addedto other standards concerning insulation materials or accesso-ries. (See Appendix X2 for sources of information.)3.3 This classification recognizes that proper handling andinstallation procedures can substantially reduc
13、e the potentialconcerns and effects. Further, it recognizes that in somesituations the presence 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 indi
14、vidual compo-nents of an insulation system with each other or the environ-mental conditions within which the system will operate, orboth, may create unanticipated effects. (See Appendix X3.)4. Basis of Classification4.1 Classification is based on several broad groupings ofpotential concerns that cou
15、ld result from direct contact withthermal insulation materials and accessories, or be caused byindirect actions or events.1This classification is under the jurisdiction of ASTM Committee C16 onThermal Insulation and is the direct responsibility of Subcommittee C16.40 onInsulation Systems.Current edi

17、rectaction or events are described as follows:4.2.1 Potential Health EffectsThose effects that createrisk of temporary or permanent changes in normal bodyfunctions and biochemical activity. The latter may involvevapors (such as organic solvent fumes), corrosive liquids(acids, alkalies, and organics)
18、, and solids (usually high surfacearea particulates) that react with body tissues or fluids.4.2.1.1 AMaterial Safety Data Sheet (MSDS) is required bythe Occupational Safety and Health Administration (OSHA),U.S. Department of Labor (29CFR 1910.1200) for hazardouschemicals produced in the United State
19、s, or imported. (TheMSDS for any product or material is issued and available fromthe organization producing the product or material.)4.2.1.2 The MSDS for any insulation product, system, oraccessory (including adhesives) should be obtained and re-viewed to determine any potential effect on humans usi
20、ng orinstalling the material.4.2.1.3 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.4.2.2 Potential Traumatic Injury Effects (Table 1)Theseeffects may result from sharp or rough material
21、s or accessorieswhich have protrusions or abrasive surfaces, cause overheat-ing, or transmit electrical energy, and generally require directcontact with the material or accessory causing lacerations,abrasions, punctures, etc.4.2.3 Potential Effects Resulting from Combustion (Table2) Those effects th
22、at 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.4.2.4 Potential Effects from Structural Conditions (Table3)Those effects that resu
23、lt 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.5.

COMMENTARYX1.1 Background of StandardThe original concept wasto develop two standards that alert task groups writing stan-dards to safety and health con
29、cerns associated with thermalinsulation materials and accessories during installation andafter installation. Classification C 930 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 c
30、lassification standard proceededthrough a number of drafts, with several new approaches to theclassification and information presented. Finally it was agreedthere was sufficient similarity between the existing standard(Classification C 930 80) and the proposed, so that theyshould be combined into on
31、e standard (Oct. 1982 Subcommit-tee meeting).X1.1.2 This revision combines the concerns and effectsassociated 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 docum
32、ent intended solely to alertstandards writers and users of insulating materials and acces-sories to 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 a
33、vailable to manufacturers and users, eventhough it is recognized that many of these are routinely used.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
34、C930 80,many requests to add qualifying or explanatory phrases andfootnotes that indicate increased 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 no
35、ting palliativemeasures and assigning degrees of risk to some products andnot others. Consequently it was agreed that the tables shouldnot contain comparative risk information.X1.1.5 The tables are non-qualitative, non-quantitative listsof potential hazards to be used by standards writers, manufac-t
36、urers, and users who are responsible for taking the potentialsinto account. Thus they are no more, no less, than checklists.X1.1.6 Since adoption of Classification C 930 85, anOSHA (Occupational Safety and Health Administration, U.S.Department of Labor) Regulation on Hazard Communication29CFR 1910.1

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 Classificat
44、ion C 930 85:X1.2.1 Descriptions of Terms Specific to This StandardThis section replaced the former Section 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 o
45、ccur during the life cycle (installation, service,removal, and disposal) of insulation materials and accessories,and points out that remedial or preventative steps are notidentified.X1.2.3 Basis of ClassificationThis section replaced theprevious 3, “General Types of Hazard” of ClassificationC 930 80
46、. It reflects a new approach to the grouping andidentification of potentials. All sections are concerned withpotentials that may occur during and after installation.X1.2.4 Table 1, Potential Health EffectsThe terminologyof products, etc., were upgraded and the quantifiers wereremoved from “potential
47、 effects on humans.”X1.2.5 Table 2, Potential for Traumatic InjuryThis tablereplaced the former Table 2, “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
48、 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. All items listed in the previous Table 4 ofClassificatio
