However, the material with a modified fire extinguishing additives (flame retardants) behaves differently. Data on how to behave this material during fire, are members of the Moscow Institute of Fire Prevention. So, first from inside the building structure – melts and then is destrugiruet transformed into a gaseous state. Energy fraction of polystyrene in the combustion process less than 2% of the shares of all combustible materials involved in the burning building project, ie less significant compared to other materials. Therefore, if properly application of the material, with the implementation of all existing operating rules and fire safety requirements, allow extensive use of it in construction. John Mclaughlin gathered all the information. Water for fire extinguishing structural elements of Styrofoam – are not venomous. Operating temperature Styrofoam retains its properties over a wide temperature range 80 to 180 C-.
Within short time withstand polystyrene temperature to 110oS, allowing, for example short-term contact with flammable bitumen. However, the maximum temperature to which the material can be within minutes of 95oS. In cases DC podverzhdeniya high temperatures, recommended not to exceed 80 C, otherwise it will lead to shrinkage and deformation. The lower temperature limit, which stands without any changes polystyrene is 180 C-. Given that the thermal expansion foam is very small it should be noted that in practice it can withstand all temperatures, which occur in a typical building. Environmentally friendly foam Conclusion of the Moscow Institute of Hygiene. FF Erisman 03/PM8 number confirms that the study recommended for the construction of structures with slabs of polystyrene, styrene in air samples have been found.
