Abstract

This study was undertaken to investigate fire risk characteristics of the plastics foam that is used an insulating materials in workplaces. The ignition characteristics and combustion gas of the plastics foam were carried out using the ISO self-Ignition tester, the Cone Calorimeter, and NES combustion analyzer. The experimental materials used were commercial samples and their composition is not disclosed by the manufacturer. As the experimental results, the self-ignition temperature of the plastics foam ranges from $410^{\circ}C$ to $510^{\circ}C$, and the flash-ignition temperature of plastics foam ranges from $370^{\circ}C$ to $450^{\circ}C$. The difference of ignition temperature on density with plastics foam type was smaller since the amount of combustible gas to ignite is not caused enough. The time to ignition of the polyethylene foam in samples of the plastics foam was shorter, and its of polyethylene foam was longer. The concentration of carbon dioxide of the polyethylene foam shows higher in samples of the plastics foam. It is found that the concentration values of carbon monoxide of the plastics foam show very fatality on people during exposure of 30 minutes in fire.
