Furthermore, some manufacturers used excess formaldehyde to ensure chemical bonding of all of the urea. The industry is mitigating this issue by switching to binder materials not containing formaldehyde; some manufacturers offer agriculturally based binder resins made from soybean oil. Natural fiber insulations can be used loose as granulats or formed into flexible or semi-rigid panels and rigid panels using a binder (mostly synthetic such as polyester, polyurethane or polyolefin). It has little structural strength but can provide racking strength and insulation with comparable or superior R-values depending on the ratio of hemp to binder. UFFI provides little mechanical strength, as the material is weak and brittle. Epoxy is too expensive to use as an insulator on its own, but it has a high R-value (7 to 9), high strength, and good chemical and moisture resistance. Environmentally friendly. Non-expansive (good for existing homes where interior sheathing is in place). Laiserin, J. (2003) "The BIM Page Archived 2015-07-08 at the Wayback Machine", The Laiserin Letter.

Knutt, Elaine (16 July 2015). "Spain launches BIM strategy with pencilled-in 2018 mandate". The technical definitions vary between countries so the United Nations created the Globally Harmonized System of Classification and Labeling of Chemicals, which defines the flash point temperature of flammable liquids as between 0 and 140 °F (60 °C) and combustible liquids between 140 °F (60 °C) and 200 °F (93 °C). The South African BIM Institute, established in May 2015, aims to enable technical experts to discuss digital construction solutions that can be adopted by professionals working within the construction sector. They can be used for ceilings, floors, walls, and roofs. Sheep's wool has no reduction in performance even when condensation is present, but its fire retarding treatment can deteriorate through repeated moisture. Most commercial insurance companies hire a risk control specialist whose primary job is to survey property to ensure compliance with NFPA standards, assess the current risk level of the property, and make recommendations to reduce the probability of fire loss.
The Chief Fire Prevention Officer or Chief of Fire Prevention will normally train newcomers to the Fire Prevention Division and may also conduct inspections or make presentations. They may or may not require fire retardants or anti-insect/pest treatments. As a result, only half of the required buildings have fire plans, and of those, only around 10 percent are up-to-date. Some insulation materials have fire or health risks, some so significant the materials are no longer allowed to be used but remain in use in some older buildings such as asbestos fibers and urea. Buildings with elaborate emergency systems may require the assistance of a fire protection consultant. This does not affect the effectiveness of the insulation, but may require choosing an installer more carefully, as any batt should be cut to fit the cavity well. Insulation may be categorized by its composition (natural or synthetic materials), form (batts, blankets, loose-fill, spray foam, and panels), structural contribution (insulating concrete forms, structured panels, and straw bales), functional mode (conductive, radiative, convective), resistance to heat transfer, environmental impacts, and more. Steen et al.: The Straw Bale House, 1994). Using a straw bale in-fill sandwich roof greatly increases the R value. When building a house, they are glued together and secured with lumber.
Fire safety is often a component of building safety. All programs tend to mix messages of general injury prevention, safety, fire prevention, and escape in case of fire. These are usually entertaining and designed to capture children's attention and relay important messages. There are no mandated or national best practice BIM standards or protocols in South Africa. Organisations implement company-specific BIM standards and protocols at best (there are isolated examples of cross-industry alliances). Capital Facilities Industry. National Institute of Standards and Technology. In June 2016, McKinsey & Company identified 5D BIM technology as one of five big ideas poised to disrupt construction. A 3D virtual model can also be created by creating a point cloud of the building or facility using laser scanning technology. The "As-Built" BIM model is populated with relevant building component information such as product data and details, maintenance/operation manuals, cut sheet specifications, photos, warranty data, web links to product online sources, manufacturer information and contacts, etc. This database is made accessible to the users/owners through a customized proprietary web-based environment. A full implementation of BIM also requires the project teams to collaborate from the inception stage and formulate model sharing and ownership contract documents.
