Prediction of Smoke Risk Ratings in the Combustion of Different Species of Wood

Abstract

In this study, smoke performance index-V and smoke growth index-V were calculated to expand Chung's equations 1, 2, and 3 and to standardize smoke hazard rating evaluation in case of fire. For this purpose, six types of wood were selected and measured by the cone calorimeter method according to ISO 5660-1. Also, overall, smoke risk was graded by smoke risk index-VI according to Chung's equation-VI. As a results, smoke hazard index-VI was found in the order of oyster oak (0.03) ≈ chestnut (0.04) ≈ zelkova (0.08) < PMMA (1.00) < pitch pine (3.13) < spruce (10.08) < lauan (11.65). Therefore, it was predicted that oyster oak, chestnut, and zelkova had the lowest smoke risk, and lauan had the highest. However, the average concentration of carbon monoxide in the specimen is 53-142 ppm, which is higher than the OSHA limit (PEL), it is concerned that it will harm health.
