    Notes: The flammability and ignitability of polyethylene using antimony trihalide compounds as fire retardants was evaluated by standard methods to determine retardant effectiveness. Compared with other retardants, the antimony trihalide compounds, antimony tribromide and antimony trichloride, substantially reduced both the flammability and the ignitability of the polyethylene. The influence of retardant concentration, heat flux and type of polyethylene was also studied.

    A study of the synergistic action of antimony oxide in fire-retardant polyethylene (1991)
    New York, NY [u.a.] : Wiley-Blackwell
    Fire and Materials 15 (1991), S. 37-42

    Notes: The fire-retardant effectiveness of mixtures of hexabromocyclododecane (HBCD) and artimony oxide (Sb2O3) in polyethylene (PE) was examined utilizing differential thermal analysis (DTA), gas chromatography/mass spectroscopy (GC/MS) and limited oxygen index (LOI) techniques. It was determined that the normal practice of mixing Sb2O3 with HBCD induced a synergistic chemical reaction at 250°C whose main product, SbBr3, was responsible for enhanced fire retardancy. The mixing of SbBr3 directly into the PE produces a superior fire-retardant polyethylene.

    Mathematical modelling of LPG tanks subjected to full and partial fire engulfment (1990)
    Chichester [u.a.] : Wiley-Blackwell
    International Journal for Numerical Methods in Engineering 30 (1990), S. 629-646

    Notes: This paper describes the use of field and zone modelling techniques in studying the behaviour of LPG tanks when subjected to accidental fire conditions. The field modelling approach is used to determine the free convective flows and heat transfer in both the vapour and the liquid regions, and also the heat transfer through the tank wall. Zone modelling techniques are employed to calculate the fire heat flux and the radiation heat transfer from the vapour wetted wall to the liquid/vapour interface. The model is verified by comparing predicted results with full scale experimental data obtained by the Health and Safety Executive, U.K.1 The comparisons indicate that the model can accurately predict the tank pressure and time to first valve opening. The model is used to investigate the effect of fire exposure level on the tank behaviour.

    To BLEVE or not to BLEVE: Anatomy of a boiling liquid expanding vapor explosion (1993)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: The loss of containment (LOC) for Pressure Liquefied Gas (PLG) vessels under accidential fire engulfment is shown to be very complex. The LOC depends upon: (i) the extent and intesity of external heating, (ii) the pressure relief device (PRD) operation and flare (if contents flammable), (iii) the fluid and fill level, (iv) the construction of the vessel, and (v) the thermohydraulic history of the commodity prior to failure.The Simple experiments described here shows that there exists a new type of more powerful failure than the BLEVE. This even we call a BLCBE, a Boiling Liquid Compressed Bubble Explosion. A hypothesis is advanced to explain this mode of failure which is supported by an initial series of small scale experiments involving Argon, water, R11, and R123.A comprehensive test program to determine the details of the BLCBE and BLEVE failure modes is indicated along with work to determine methods of protection.
