4.3 Indication of immediate medical attention and special treatment needed, if necessary

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.

5.Fire-fighting measures

5.1 Extinguishing media

Suitable extinguishing media

5.2 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)

5.3 Special protective actions for fire-fighters

Wear self-contained breathing apparatus for firefighting if necessary.

6.Accidental release measures

• Toxicity to microorganisms: no data available

12.2 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).

12.3 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.

12.4 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).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

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.

Contaminated packaging

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.
