ASTM C930-19

Standard Classification of Potential Health and Safety Concerns Associated With Thermal Insulation Materials and Accessories

SIGNIFICANCE AND USE
4.1 The purpose of this classification is to identify potential concerns and effects which may occur during the life cycle (installation, service, removal, and disposal) of insulation materials and accessories resulting from direct contact or indirect action or events.  
4.2 This classification does not identify remedial or preventive steps that may be taken to correct potential problems or hazards; rather it is intended as a checklist that will make it easier to deal constructively with these potentials, and to determine what, if any, specific requirements need to be added to other standards concerning insulation materials or accessories. (See Appendix X2 for sources of information.)  
4.3 This classification recognizes that proper handling and installation procedures can substantially reduce the potential concerns and effects. Further, it recognizes that in some situations the presence or creation of potential effects or hazards results from an intervening act of human or natural origin, or depends on access to or contact with the materials or accessories. Lack of compatibility of the individual components of an insulation system with each other or the environmental conditions within which the system will operate, or both, may create unanticipated effects. (See Appendix X3.)
SCOPE
1.1 This classification identifies potential concerns and effects that could result from direct contact with thermal insulation materials and accessories, or be caused by indirect action of events such as aging, fire, or physical disturbance.  
1.2 Intent of Classification:  
1.2.1 It is the intent of this classification to alert others to potential concerns, effects, hazards, or risk.  
1.2.2 It is not the intent of this classification to establish the degree of risk or hazard or limiting values of potential hazards.  
1.2.3 It is not the intent of this classification to establish or recommend methods or markings to reduce or mitigate the potential; however, it is recognized that correct procedures and precautionary measures can substantially reduce or eliminate some of the potential concerns, effects, hazards, or risks.  
Note 1: See Appendix X1 for commentary.  
1.3 This classification recognizes the responsibility of producers and users, as appropriate, to: (1) provide information on known effects or hazards, (2) advise on established safety and health practices, and (3) determine applicable regulatory requirements.  
1.4 This classification does not address the health and safety concerns of thermal insulation materials and accessories during manufacture.  
1.5 Omission of an item from this classification does not imply an absence of potential concerns or effects.  
1.6 There is no importance in the order of listing.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM C930-19 - Standard Classification of Potential Health and Safety Concerns Associated With Thermal Insulation Materials and Accessories - provides a comprehensive checklist identifying potential health and safety concerns arising from the use of thermal insulation materials and related accessories throughout their lifecycle: installation, service, removal, and disposal. Developed by ASTM Committee C16, this international standard is designed to support manufacturers, specifiers, installers, and users in recognizing possible issues arising from direct contact or indirect events such as fire, aging, or disturbance of insulation systems.

While ASTM C930-19 does not prescribe remedial actions or establish degree of risk, it serves as a structured resource to help stakeholders address or preempt potential concerns by reviewing system compatibility and handling practices, and by referencing existing regulatory requirements.

Keywords: thermal insulation, health effects, safety concerns, installation, removal, ASTM C930, insulation system compatibility, structural hazards, fire safety

Key Topics

Potential Health and Safety Effects Identified:

• Direct Contact Hazards: Risks associated with physical contact, including cuts, abrasions, punctures, thermal burns, or exposure to hazardous chemicals present in insulation materials or accessories.
• Indirect Action/Event Hazards: Issues triggered by events such as aging, fire, physical disturbance, or incompatibility with other materials, potentially leading to hazardous emissions, structural failure, or combustion byproducts.
• Combustion and Fire Hazards: Concerns arising from smoke, toxic gases, heat generation, and reduced visibility during fire events involving insulation materials.
• Structural Impact: Potential weakening or failure of building structures due to overloading or material deterioration, possibly leading to collapse.
• Electrical Hazards: Possibility of electrical shock or fire from insulation in contact with wiring, especially if insulation is conductive or if old wiring is present.
• Material Compatibility: Risks of unexpected reactions or failures due to incompatibility between system components or unsuitable environmental conditions.

Responsibilities:

• Producers and users are responsible for providing information on known hazards, advising on safe handling, and identifying applicable regulatory requirements.
• Safety Data Sheets (SDS) should be reviewed for all materials to determine health and safety impacts.

Applications

Practical Uses of ASTM C930-19:

• Standards Development: Assists technical committees and standards writers in considering health and safety aspects when drafting requirements for insulation materials.
• Specification and Procurement: Supports architects, engineers, and specifiers in evaluating potential concerns before selecting products for projects.
• Installer Awareness: Acts as a checklist for installers to identify possible hazards during installation, removal, or maintenance procedures, emphasizing proper handling to mitigate risks.
• Risk Assessment: Enables facility managers and safety professionals to identify potential issues throughout the lifecycle of insulation, informing risk management strategies.
• Compliance and Regulation: Provides a reference for meeting regulatory requirements concerning health and safety during use of insulation products.

4. Significance and Use
4.1 The purpose of this classification is to identify potential concerns and effects which may occur during the life cycle
(installation, service, removal, and disposal) of insulation materials and accessories resulting from direct contact or indirect action
or events.
4.2 This classification does not identify remedial or preventive steps that may be taken to correct potential problems or hazards;
rather it is intended as a checklist that will make it easier to deal constructively with these potentials, and to determine what, if
any, specific requirements need to be added to other standards concerning insulation materials or accessories. (See Appendix X2
for sources of information.)
4.3 This classification recognizes that proper handling and installation procedures can substantially reduce the potential
concerns and effects. Further, it recognizes that in some situations the presence or creation of potential effects or hazards results
from an intervening act of human or natural origin, or depends on access to or contact with the materials or accessories. Lack of
compatibility of the individual components of an insulation system with each other or the environmental conditions within which
the system will operate, or both, may create unanticipated effects. (See Appendix X3.)
5. Basis of Classification
5.1 Classification is based on several broad groupings of potential concerns that could result from direct contact with thermal
insulation materials and accessories, or be caused by indirect actions or events.
5.2 Potentials that occur from direct contact or indirect action or events are described as follows:
5.2.1 Potential Health Effects—Those effects that create risk of temporary or permanent changes in normal body functions and
biochemical activity. The latter may involve vapors (such as organic solvent fumes), corrosive liquids (acids, alkalies, and
organics), and solids (usually high surface area particulates) that react with body tissues or fluids.
5.2.1.1 A Safety Data Sheet (SDS) is required by the Occupational Safety and Health Administration (OSHA), U.S. Department
of Labor (29 CFR 1910.1200) for hazardous chemicals produced in the United States, or imported. (The SDS for any product or
material is issued and available from the organization producing the product or material.)
5.2.1.2 The SDS for any insulation product, system, or accessory (including adhesives) should be obtained and reviewed to
determine any potential effect on humans using or installing the material.
5.2.1.3 When tests are included in a standard, the SDS for chemicals required should be reviewed to ensure that proper guidance
for safe handling and use is incorporated.
5.2.2 Potential Traumatic Injury Effects (Table 1)—These effects may result from sharp or rough materials or accessories which
have protrusions or abrasive surfaces, cause overheating, or transmit electrical energy, and generally require direct contact with the
material or accessory causing lacerations, abrasions, punctures, etc.
5.2.3 Potential Effects Resulting from Combustion—Those effects that result principally from the emission of heat, gases (toxic
and non-toxic), fibers, particulates, and depletion of oxygen which takes place during combustion that exposes or involves
insulation materials or accessories. The exposure effects can result from the actual combustion process or from the effluents that
originate as a consequence of the combustion. Combustion can cause thermal effects (burns or scalds), toxic effects (resulting from
the inhalation of asphyxiant or irritant combustion products, typically contained in the vapor phase), dermal effects (such as skin
irritation) and impaired vision due to smoke obscuration, obscuration. In some cases, smoke, or some toxicants contained in smoke,
can cause eye irritation and other health effects. The principal effect of smoke obscuration is not an actual health effect but the
resulting loss of visibility, which can impair egress or rescue, or both, in case of fire. The effects resulting from combustion (or
fire) are a function of the material (or materials) involved in the fire, the fire scenario and the amount of material that has burnt.
Any combustible insulation material has the potential to be involved in fires. ASTM Committees E05 (on Fire Standards), E34 (on
Occupational Health and Safety) and F23 (on Protective Clothing), as well as NFPA (National Fire Protection Association), SFPE
(Society of Fire Protection Engineers) are potential resources to better understand the effects of combustion or fire.
5.2.4 Potential Effects from Structural Conditions (Table 2)—Those effects that result principally from the overloading or
deterioration of structural members of a building resulting in failure of the structure, or a portion of it, and its collapse on
occupants.
5.2.5 Guidance on Burn Injuries. Guide C1055 provides guidance on burn injuries associated with heated system surface
contacts.
