PVC is often used as the insulating sheath on electrical cables. PVC is chosen because of its good electrical insulation, ease of extrusion, and resistance to burn. [40] In a fire, PVC can form hydrogen chloride fumes; the chlorine serves to scavenge free radicals, making PVC-coated wires fire retardant.
Due to its toxic nature, vinyl chloride is not found in other products. Poly(vinyl chloride) (PVC) is very stable, storable and not toxic. [2] Until 1974, vinyl chloride was used in aerosol spray propellant. [7] Vinyl chloride was briefly used as an inhalational anaesthetic, in a similar vein to ethyl chloride, though its toxicity limited this use.
The U.S. Flammable Fabrics Act is an act that was passed in 1953 to regulate the manufacture of highly flammable clothing. [1] [2] It was enacted after years of rayon viscose fabrics being proven to be the primary cause of quick starting, high temperature fires as well as having the secondary effect of causing illnesses in factory workers.

The Palisades fire claimed two elementary schools and badly damaged Palisades Charter High School. But campuses near fire zones — those with buildings intact, including Odyssey, Canyon and ...
Fire-retardant materials should not be confused with fire-resistant materials. A fire resistant material is one which is designed to resist burning and withstand heat . An example of a fire-resistant material is one which is used in bunker gear worn by firefighters to protect them from the flames of a burning building.
Under the state’s administrative regulations, updated last year, new school construction is not allowed in flood zones unless the “finished floor elevation” is at least 12 inches “above ...
Chemicals on the red list may not be included in materials used in construction that seeks to meet the criteria of the Living Building Challenge (LBC). According to ILFI, the list is composed of materials that should be phased out of production due to health concerns. The list is now updated annually. [1]
Fire-safe polymers are polymers that are resistant to degradation at high temperatures. There is need for fire-resistant polymers in the construction of small, enclosed spaces such as skyscrapers, boats, and airplane cabins. [1] In these tight spaces, ability to escape in the event of a fire is compromised, increasing fire risk.
