Specific hazards arising from the chemical
Excerpt from ERG Guide 130 [Flammable Liquids (Water-Immiscible / Noxious)]: HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. (ERG, 2016)
Special protective actions for fire-fighters
Use powder, AFFF, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

Reactivity
900 ppm [IDLH based on 10% of the lower explosive limit for safety considerations even though the relevant toxicological data indicated that irreversible health effects or impairment of escape existed only at higher concentrations.]
Reacts violently with acids and strong oxidants. This generates fire and explosion hazard. The substance can form explosive peroxides.
Chemical stability
Volatile
Possibility of hazardous reactions
Flammable liquid.As a result of flow, agitation, etc., electrostatic charges can be generated.Mixing CUMENE in equal molar portions with any of the following substances in a closed container caused the temperature and pressure to increase: chlorosulfonic acid, nitric acid, oleum, NFPA 1991.

SECTION 12: Ecological information
Toxicity
- Toxicity to fish: LC50 - Cyprinodon variegatus - 4.7 mg/L - 96 h.
- Toxicity to daphnia and other aquatic invertebrates: EC50 - Daphnia magna - 2.14 mg/L - 48 h.
- Toxicity to algae: EC50 - Desmodesmus subspicatus (previous name: Scenedesmus subspicatus) - 2.01 mg/L - 72 h.
- Toxicity to microorganisms: EC50 - activated sludge of a predominantly domestic sewage - > 2 000 mg/L - 3 h. Remarks:Respiration rate.
Persistence and degradability
AEROBIC: Isopropylbenzene biodegradation in batch reactors proceeded following about 144 hr of acclimation and after 120 hr, isopropylbenzene was non-detectable. In unacclimated cultures, the half-life of isopropylbenzene was 206 hr (62 hr after acclimation)(1). When isopropylbenzene was incubated with an activated sludge acclimated to benzene, the theoretical BOD was reduced by 37.8% after 192 hr(2). A 20-day biological oxygen demand study was conducted using unacclimated, settled, domestic wastewater as the inoculum. After 10 and 20 days, the theoretical BOD was 62% and 70%, respectively(3). Activated sludge acclimated to aniline degraded isopropylbenzene following an acclimation period of about 30 hr(4). Activated sludge samples from three different communities were able to degrade 50 mg/L isopropylbenzene(5). A biodegradation rate constant of 0.322/day was calculated when 0.235-0.571 g/cu m isopropylbenzene was added to soil microcosms from a weathered petroleum spill site(6).
Bioaccumulative potential
A BCF of 35.5 was measured in goldfish which were exposed to isopropylbenzene at 1 mg/L(1,2). According to a classification scheme(3), this BCF value suggests the potential for bioconcentration in aquatic organisms is moderate.
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of isopropylbenzene can be estimated to be 700(SRC). According to a classification scheme(2), this estimated Koc value suggests that isopropylbenzene is expected to have low mobility in soil. A Kd value of 0.374 was reported for isopropylbenzene added at 113.1 ug/L to an anaerobic microcosm using aquifer material from Canada Forces Base Borden(3).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
