Bug Fixes

  • [CP037] In Kraft-faced Fiber Glass Batt Insulation, the Fiber Base component has been renamed “Biosoluble glass fibers” to be more specific about the glass fiber type most commonly used in this product profile, which has no known hazards. A new source (JM MSDS 3) has been added as a reference to this change. The nested components of Fiber Base have also been removed, which used to differentiate between recycled glass cullet and virgin glass. Lastly, the lead, mercury, and arsenic impurities associated with glass cullet have been removed. These changes affect only the health profile.
  • [CP056] In Double Pane IGU, Type I Clear, Flat Glass has been dissociated with the CASRN 65997-17-3 and its hazards. This change affects only the health profile.
  • [CP072] In Exterior Door w/ IGU, Type I Clear, Flat Glass has been dissociated with the CASRN 65997-17-3 and its hazards. This change affects only the health profile.
  • [CP092] In Copper Piping, a few sources’ links were updated. Copper was recharacterized as Copper (bulk), which is not associated with any health hazards (as opposed to the powder specific form of Copper). Silver was moved to the Impurities section as per recommendation by CDA (Copper Development Association). This change affects only the health profile.
  • [CP094] In Intumescent firestop sealant, missing sources for the following impurities were added: Quartz, Nitric Acid, Sulfuric Acid.
  • [CP115] In Granular Fill, a typo was corrected in the function of Coarse Aggregate and Crushed Stone. % weight part figures for second level components were made more precise. Gravel and Sand components in Reclaimed Concrete were missing and have now been added. This change affects only the health profile.
  • [CP123] In Mineral Fiber Batt Insulation, the Uniformat code B3040 Traffic Bearing Horizontal Enclosures was removed. Subcomponents of Mineral Wool Fibers were removed. This change affects only the health profile.
  • [CP176] In Glass Fiber Reinforced Polymer Water Storage Tank, the CASRN for the impurity Methyl Ethyl Ketone Peroxide was corrected from 1338-23-5 to 1338-23-4.
  • [CP178] In Laminated Glass, Ultraclear, Low Iron Glass has been dissociated with the CASRN 65997-17-3 and its hazards. This change affects only the health profile.
  • [CP179] In Fiber Glass Board Insulation, the Fiber Base component has been renamed “Biosoluble glass fibers” to distinguish the glass fiber type most commonly used in this product profile which has no known hazards. The nested components of Fiber Base have also been removed, which used to differentiate between recycled glass cullet and virgin glass. This change affects only the health profile.
  • Mineral wool, fiber glass and components with the CASRN 65997-17-3 are no longer further broken down by oxide content. Although glass varieties are often described by their oxide content, the Quartz research team concluded that the hazards of individual oxides do not accurately describe the hazards of glass fibers themselves. The hazards for this CASRN have been updated to include an Orange Cancer hazard. The health profiles of the following CPs were affected by this change: CP056, CP072, CP074, CP094, CP108, CP129, CP130, CP131, CP152, CP172, CP176, CP178, CP179.
  • The Coarse Aggregate component has been renamed “Gravel” to be more specific about the specific type of coarse aggregate in our profiles. This affects the following CPs: CP001, CP029, CP042, CP115, CP169, CP170.
  • The Copper component has been renamed “Copper, all forms” to distinguish between hazards that are specific to the dust form of Copper and hazards that are shared between all forms of Copper. The health profiles of the following CPs were affected by this change: CP017, CP018, CP019, CP026, CP044, CP056, CP069, CP072, CP074, CP077, CP092, CP095, CP095, CP100, CP127, CP132, CP174.

The Quartz team has been busy finding and squashing database bugs over the past few months. If you're an active user of our data, please pay careful attention to the correction details below. Many products have had minor composition changes resulting in health and environmental profile changes, while others have only had changes to source lists.

Bug Fixes

  • [CP039] In Polyester Powder Coating, duplicate components were removed. This change only affects the health profile.
  • [CP056] In Double Pane IGU, the % weight of “Airspace” component was adjusted due to a calculation error. All other weights for the components were updated to reflect the change, affecting both health and environmental profiles.
  • [CP072] In Exterior Door w/ IGU, the % weight of “Airspace” component was fixed and all other weights for components were updated to reflect the change, affecting both health and environmental profiles. Additionally, the weight changes in EPS were propagated to the “EPS Insulation” component and composition percentages were fixed for the steel encasement. Finally, the “Insulated Glazing Unit (Double Pane)” was updated to “Tempered Sheet Glass” and its sources and sub-component weights were adjusted. Hazards for PVC updated to just Developmental (orange) and Respiratory (orange).
  • [CP108] In Type X Drywall, an extra Calcium Sulfate Dihydrate component removed. This change only affects the health profile.
  • [CP115] In Granular Fill, hazards were not being displayed for components of Ground Granulated Blast Furnace Slag and incorrect percentages were being listed for chemicals that existed in multiple components. These errors have been fixed but do not affect the overall health and environment profile figures.
  • [CP120] In Expanded Polystyrene Foam (EPS), the weights for the pentane isomers were adjusted to better reflect literature sources. This change affects both health and environmental profiles.
  • [CP127] In Steel Door, an error in steel composition percentages were corrected for top and bottom channels and door skins. Overall health and environment profile figures were not affected.
  • [CP146] In Acrylic Floor Adhesive, composition adjustments were made due to an error in Gum Rosin calculations. This change affects both health and environmental profiles.
  • [CP179] In Fiberglass Board Insulation, the % weight of all the components were adjusted based on a more accurate product density value. This change affects both health and environmental profiles.
  • Hazards for PVC updated to Developmental (orange) and Respiratory (orange), which change the overall health profile for the following CPs: CP091, CP072, CP125, CP129, CP130, CP150.
  • Errors in source lists for chemicals that occur in multiple components in a single product have been corrected. Changes will be apparent at the component level. Product level sources remain the same. The following CPs have been affected: CP005, CP018, CP019, CP025, CP027, CP029, CP037, CP039, CP056, CP069, CP072, CP074, CP091, CP094, CP108, CP109, CP110, CP112, CP115, CP120, CP123, CP125, CP127, CP129, CP130, CP131, CP132, CP133, CP146, CP147, CP150, CP151, CP152, CP168, CP169, CP170, CP173, CP174, CP176, CP179.
