Fire behaviour – A preliminary study
Proceedings of the Annual Congresses of the Grassland Society of Southern Africa, 1978There is a serious deficiency in knowledge concerning the behaviour of fires in South Africa. Arising from this, an investigation was initiated to characterise the behaviour of head and back fires under a variety of environmental conditions. The results showed that head fires had a significantly greater rate of spread, length of flame and overall ...

Fire Safety Journal, 1991
Ducts are used in buildings for air venting or for smoke extraction. In both cases they have to go through fire walls. In this respect ducts have to provide enough fire resistance to avoid transfer of fire from one compartment to another. France has testing methodologies to assess the fire behaviour of ducts.

Comparison of Techniques for Visualising Fire Behaviour
Transactions in GIS, 2007AbstractDuring every Australian summer fires are common in the south‐eastern region of the continent. The combined forces of climate, topography and vegetation make Victoria in particular, one of the most fire prone regions on earth (DSE 2003). Throughout its history, Victoria has seen a number of devastating bushfires, including Black Friday 1939, Ash

Fire behaviour in the Kruger National Park
Journal of the Grassland Society of Southern Africa, 1985Fire research in the Kruger National Park has largely been focused on the effect of the season and frequency of burning on the vegetation. Very little information is available on the effect of fire behaviour and in particular fire intensity, on the flora of the park.

Motorists drive through tunnels at high speeds. In consequence, they see the tunnel in a flash and have no idea how the tunnel looks like when they have to walk in the tunnel, for example, when evacuation is required. The authorities responsible for evacuation (and escape signs) are experts who fail to see the tunnel the way the general public does ...

Fire behaviour of polyester–clay nanocomposites
Fire and Materials, 2005AbstractThe aim of this study was on the one hand, to compare the fire behaviour of polyester/clay nanocomposites with that of the neat polymers added with the conventional flame retardant melamine isocyanurate (MIC) and on the other hand, to study the effect of the flame retardant added to the nanocomposites.Polyester/clay nanocomposites were prepared

The effect of fire front width on surface fire behaviour
International Journal of Wildland Fire, 2000To determine the effect of fire front width on surface fire spread rates, a series of simultaneously ignited experimental fires was carried out in a pine plantation. Fires were ignited in plots with widths ranging from 0.5 m to 10 m and were burned in low wind conditions. Flame lengths were small in all fires, ranging from 20 cm to 60 cm.

Fire retardants and product behaviour in fire tests
Polymer International, 2000Fire safety aspects of polymeric materials in various types of use have led to finding effective ways to reduce the ease of ignition, flame spread and heat evolved as well as the amount of smoke, toxic and corrosive gases produced. Depending on the polymer and the end‐use application of the product, different fire‐retardant methods are used with the ...

Predicting Fire Behaviour with Fire Danger Tables
Australian Forestry, 1968SUMMARY The factors used in the construction of McArthur's (1958) fire danger tables are discussed briefly. The use of the tables to estimate fire danger and predict fire behaviour is discussed, and the effects of fuel quantity, fuel types, slope, diurnal changes in fuel moisture content, recent rainfall, large fuel components, and a number of other ...

The behaviour of lithium batteries in a fire
Journal of Power Sources, 1989Abstract Fire trials are described that involved all of the types of lithium primary cells commercially available in the U.K. and of interest for Defence applications. The electrochemical system and the design of the cell case caused major differences in behaviour. These are discussed, and hazards to personnel evaluated. The efficacy of a water spray
