Collect leaking liquid in sealable containers. Absorb liquid in sand or inert absorbent. Then store and dispose of according to local regulations.
Methods and materials for containment and cleaning up
First remove all sources of ignition. Then, use absorbent paper to pick up all liquid spill material. Your contaminated clothing and absorbent paper should be sealed in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with 60-70% ethanol followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.
Precautions for safe handling
NO open flames. 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
Provision to contain effluent from fire extinguishing. Separated from strong oxidants. Ventilation along the floor. Store in an area without drain or sewer access.... store this chemical under refrigerated temperatures, and keep it away from oxidizing materials. STORE AWAY FROM SOURCES OF IGNITION.

Persistence and degradability
Both 1- and 2-chloronaphthalene were metabolized by Pseudomonads grown on naphthalene as the sole source of carbon and energy(1). Using a sewage sludge inoculum grown on naphthalene, it was shown that 1- and 2-chloronaphthalene were both degraded on incubation with the inoculum(1). The metabolism of 1-chloronaphthalene by two species of naphthalene utilizing bacteria has been investigated(2). The bacteria were grown in mineral salts medium at pH 6.9, with 1-chloronaphthalene added as the sole source of carbon. Two metabolites were isolated 8-chloro-1,2-dihydro 1,2-dihydroxynaphthalene and 3-chlorosalicylic acid. These metabolites demonstrated that the initial site of bacterial degradation is the ring which does not contain the chlorine constituent(2).
Bioaccumulative potential
BCF values in the range of 142-338 were measured for carp exposed to 0.005 mg/l solutions of 1-chloronaphthalene during an 8 week incubation period. BCF values in the range of 142-403 were measured for carp exposed to 0.05 mg/l solutions of 1-chloronaphthalene during an 8 week incubation period. According to a classification scheme(2), these BCF values suggest bioconcentration in aquatic organisms is high(SRC).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for 1-chloronaphthalene can be estimated to be 3000(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1-chloronaphthalene is expected to have slight mobility in soil(SRC).
Other adverse effects
