Sweep spilled substance into sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.
Methods and materials for containment and cleaning up
Despite the use of solvent extraction as a means of separating organic materials, its application to wastewater treatment generally has been limited to removal of phenol & its compounds present at high concentrations. This paper provides a systematic methodology of the extraction problem, which may be used to establish the treatability criteria for organic priority pollutants. The treatabilities are calculated based on distribution coefficients & extraction column models in the literature. Distribution coefficients (estimated) for 2-chloronaphthalene & other pollutants in various solvents are given.

Persistence and degradability
Chlorinated naphthalenes are more resistant to biodegradation than naphthalene (a readily biodegradable compound). ... The higher the degree of chlorination the more slowly /a particular/ chloronaphthalene will be degraded . Chloronaphthalenes containing chlorosubstituents in both rings may be more resistant to biodegradation than chloronaphthalenes containing chlorine in only one ring. Chloronaphthalenes
Bioaccumulative potential
After 7 days exposure to water concn ranging from about 100 to 750 ug/l, the bioconcentration factor of 2-chloronaphthalene in the tissue of one year old, female guppies (Poecillia reticulata) was 4300(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is very high(SRC).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for 2-chloronaphthalene can be estimated to be 3,000(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2-chloronaphthalene is expected to have slight 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.
