Fresh air, rest. Refer for medical attention.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
Rinse with plenty of water (remove contact lenses if easily possible).
Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.
Narcotic action with long-lasting effects; depressant to central nervous system. (USCG, 1999)
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Aromatic hydrocarbons and related compounds
To fight fire, use foam, carbon dioxide, dry 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)
Use powder, AFFF, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.
Personal protection: chemical protection suit and filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT let this chemical enter the environment.

NO open flames, NO sparks and NO smoking. Above 31°C use a closed system, ventilation and explosion-proof electrical equipment. Prevent build-up of electrostatic charges (e.g., by grounding). Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Fireproof. Separated from strong oxidants and acids. Cool. Keep in the dark. Store only if stabilized. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing.... Precautions ... such as mounds around storage tanks, sills at doorways or especially designed floors /are needed/ to limit spread of escaping liquid. Open flames & other sources of ignition should be excluded where cumene is stored.

Reacts violently with acids and strong oxidants. This generates fire and explosion hazard. The substance can form explosive peroxides.
Volatile
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.

Evaluation: No data were available from studies in humans. There is sufficient evidence in experimental animals for the carcinogenicity of cumene. There is sufficient evidence in experimental animals for the carcinogenicity of alpha-methylstyrene. Cumene is possibly carcinogenic to humans (Group 2B). alpha-Methylstyrene is possibly carcinogenic to humans (Group 2B).
No information is available on the reproductive or developmental effects of cumene in humans. Inhalation studies in rats and rabbits reported no significant adverse effects on reproduction or fetal development. No effects on sperm were observed in male rats exposed by inhalation.
If swallowed the substance easily enters the airways and could result in aspiration pneumonitis. The substance may cause effects on the central nervous system. Exposure far above the OEL could cause unconsciousness.
Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the liver and upper respiratory tract. This substance is possibly carcinogenic to humans.
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C.
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).
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.
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).

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.
