SECTION 4: First aid measures
Description of necessary first-aid measures
Fresh air, rest.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Give one or two glasses of water to drink. Refer for medical attention .
Most important symptoms/effects, acute and delayed
Exposure Routes: inhalation, skin absorption, ingestion, skin and/or eye contact Symptoms: Pain, burn eyes, lacrimation (discharge of tears), conjunctivitis; erythema (skin redness) eyelids, blepharospasm; irritation throat, cough, chest tightness; headache; erythema (skin redness), skin vesiculation Target Organs: Eyes, skin, respiratory system (NIOSH, 2016)
Indication of immediate medical attention and special treatment needed, if necessary
Rapid support of respiration and circulation is essential to successful treatment of cyanide intoxication. Massive cyanide overdoses have survived with only good supportive care. Immediate attention should be directed toward assisted ventilation, administration of 100% oxygen, insertion of intravenous lines, and institution of cardiac monitoring. Obtain an arterial blood gas immediately and correct any severe metabolic acidosis (pH below 7.15). Oxygen (100%) should be used routinely in moderate or severely symptomatic patients even in the presence of a normal pO2, since 100% O2 increases O2 delivery, may reactivate cyanide-inhibited mitochondrial enzymes, and potentiates the effect of thiosulfate. Avoid mouth to mouth resuscitation during CPR in order to prevent self poisoning. Cyanides

Methods and materials for containment and cleaning up
1. ventilate area of spill. 2. for small quantities, sweep onto paper or other suitable material, place in appropriate container & burn in safe place (such as fume hood). large quantities may be reclaimed; however, if this is not practical, dissolve in flammable solvent (such as alcohol) & atomize in suitable combustion chamber equipped with appropriate effluent gas cleaning device. 3. decontaminate area of spill: (a) by washing with a 5% solution of sodium hydroxide in 50/50 ethyl alcohol/water; or (b) by adding flake sodium hydroxide to a solution or slurry of the spill in isopropyl alcohol; or (c) by covering the spill with a 10% solution of sodium hydroxide in 50/50 isopropyl alcohol/water & letting stand 20 minutes before flushing with water.
SECTION 7: Handling and storage

- Toxicity to daphnia and other aquatic invertebrates: no data available
- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
Persistence and degradability
no data available
Bioaccumulative potential
An estimated BCF of 30 was calculated for 2-chlorobenzalmalononitrile(SRC), using an estimated log Kow of 2.76(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.
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for 2-chlorobenzalmalononitrile can be estimated to be 1700(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2-chlorobenzalmalononitrile is expected to have low mobility in soil.
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.
