In Japan, cardboard beds are used in many disaster shelters, and research on the combustibility of cardboard beds has been conducted with the aim of further improving the safety of shelters environment. Here, the combustibility of the flame-retardant cardboard bed is considered by using the maximum combustion calorie, its arrival time, and the rapid rise time as the evaluation standard of combustion behavior. The effects of changes in the types of flame-retardant cardboard beds and parameters of installation intervals are considered on combustion behavior. From these results, it is shown that the flame retardant treatment can delay the combustion and when installed at intervals of 800 mm, it can prevent fire spread.
There is a relationship between the flame-retardant treatment and the cardboard bed, and that flame retardancy have possibility of increase the risk of fire within a certain distance.
