4.2 Most important symptoms/effects, acute and delayed

This material is toxic by ingestion and inhalation. It produces disturbances of the respiration and circulation, irritation of the stomach and intestine, and loss of weight. It is irritating to skin and eyes. (EPA, 1998)

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

A person who has inhaled the vapors should be moved to an uncontaminated environment, and cardiopulmonary resuscitation should be administered. If the victim breathes with difficulty, oxygen should be given. In case of eye contact, flush with copious water for at least 20 min and call a physician. In case of ingestion, induce vomiting and call a physician. For skin contact, wash with plenty of soap and water.

5.Fire-fighting measures

5.1 Extinguishing media

Suitable extinguishing media

USE WATER SPRAY, DRY CHEMICAL, FOAM OR CARBON DIOXIDE. USE WATER SPRAY TO KEEP FIRE-EXPOSED CONTAINERS COOL. APPROACH FIRE FROM UPWIND TO AVOID HAZARDOUS VAPORS AND TOXIC DECOMPOSITION PRODUCTS.

5.2 Specific hazards arising from the chemical

Combustion products may contain hydrogen cyanide (hydrocyanic acid, HCN). Vapor may explode if ignited in an enclosed area. When heated to decomposition, it emits highly toxic fumes. Avoid oxidizing material. Hazardous polymerization may not occur. (EPA, 1998)

5.3 Special protective actions for fire-fighters

Wear self-contained breathing apparatus for firefighting if necessary.

6.Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures

Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.

6.2 Environmental precautions

Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT wash away into sewer.

6.3 Methods and materials for containment and cleaning up

Stop or control the leak, if this can be done without undue risk. Use water spray to cool and disperse vapors, and protect personnel. Approach release from upwind. Absorb in noncombustible material for proper disposal.

7.Handling and storage

7.1 Precautions for safe handling

Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.

12.2 Persistence and degradability

AEROBIC: Adiponitrile had a 5-day theoretical BOD of 40% in a river die-away study using unacclimated Ohio River water, 0.5-10 mg/l substrate concn and sewage inocula(1); a 12-day theoretical BOD was >100%(1); negligible degradation was observed after 2 days(1). At a substrate concn of 40 mg/l and 20°C, adiponitrile had theoretical CO2 evolutions of 10 and 60% after 2 and 9 days, respectively, in river die-away studies using unacclimated Ohio River water and sewage inocula(1); at 5°C, theoretical CO2 evolution was 10 and 60% after 7.5 and 33 days, respectively(1). At 20°C, effects of acclimation were examined by redosing at an initial substrate concn of 40 mg/l; the ratio of time it took to achieve 60% oxidation on 1st and 2nd feeding was 2.1 to 1(1). Adiponitrile was found to be toxic to one activated sludge unit after 72 hrs with a metal substrate concn of 500 mg/l; the other two sludge units had 2.2-2.8% theoretical BOD(2). Using a bench scale activated sludge unit, 93-98% BOD removal of adiponitrile was achieved using an influent concn equivalent to 275-350 mg/l BOD and a mean aeration retention time of 7-13 hours(3). Adiponitrile, present at 30 mg/l, reached 85% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 100 mg/l and the Japanese MITI test(4). Microorganisms (Aeromonas sp.) isolated from soil were able to use adiponitrile as their sole source of carbon(5).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated for adiponitrile(SRC), using a log Kow of -0.32(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

The Koc of adiponitrile is estimated as 16(SRC), using a measured log Kow of -0.32(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that adiponitrile is expected to have very high mobility in soil(SRC).

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.
