Personal precautions, protective equipment and emergency procedures
Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.
Environmental precautions
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
Methods and materials for containment and cleaning up
Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.
Precautions for safe handling
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.
Conditions for safe storage, including any incompatibilities
Store the container tightly closed in a dry, cool and well-ventilated place. Store apart from foodstuff containers or incompatible materials.

Exposure controls
Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Individual protection measures
Eye/face protectionWear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).
Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
If the exposure limits are exceeded, irritation or other symptoms are experienced, use a full-face respirator.

Persistence and degradability
A partially purified enzyme of the soil fungus Geotrichum candidum converted 5-chloro-o-toluidine to 4,4'-dichloro-2,2'' dimethylazobenzene(2). The same compound was isolated when 5-chloro-o-toluidine (obtained from hydrolysis of chlordimeform) was incubated in soil for 90 days(1). In addition, three other oxidation products were detected(1). The rate of loss of 5-chloro-o-toluidine in soil as a result of these reactions was not measured(1).
Bioaccumulative potential
Using an estimation method(2), a log Kow value of 2.58 has been estimated for 5-chloro-o-toluidine. Based on this log Kow and a recommended regression equation(1), the bioconcentration factor for 5-chloro-o-toluidine has been estimated to be 54(SRC). Therefore, bioconcentration of 5-chloro-o-toluidine in aquatic organisms should not be important.
Mobility in soil
Based on an estimated log Kow of 2.58 and a recommended regression equation(1), a log Koc of 2.37 has been estimated for 5-chloro-o-toluidine(SRC). This value indicates that 5-chloro-o-toluidine may be moderately mobile in soil(2). However, primary aromatic amines can react with humic matter in soil forming an irreversible complex and as a result may be immobilized in soil(3-4). With the increase in humic matter in soil, the tendency of irreversible complex formation may increase and 5-chloro-o-toluidine may become increasingly immobilized. In sandy soil containing a marginal amount of humic matter, 5-chloro-o-toluidine may be mobile(5,SRC).
Other adverse effects

Disposal methods
ProductThe 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.
