暴露限值Flammable liquid; flash point (closed cup) 36°C (97°F) (NFPA 1986), 39°C (102°F) (Merck 1996), 35.5°C (96°F) (Meyer 1989); vapor pressure 8 torr at 20°C (68°F); vapor density 4.1 (air=1); the vapor is heavier than air and may travel a considerable distance to a nearby ignition source and flash back; autoignition temperature 425°C (797°F); fire- extinguishing agent: dry chemical, foam, or CO2; use a water spray to keep fire- exposed containers cool and to disperse the vapors。
Cumene forms explosive mixtures in the air within the range 0.9–6.5% by volume in air. Cumene may form peroxide on prolonged exposure to air. It should be tested for peroxides before it is subjected to distillation or evaporation。.

稳定性稳定，但如果与空气接触，可能会在储存中形成过氧化物。在加热或蒸馏之前测试过氧化物的存在。易燃。与强氧化剂不相容。
