Description of first aid measures
If inhaledFresh air, rest. Refer for medical attention.

Most important symptoms and effects, both acute and delayed
Exposure Routes: inhalation, skin absorption, ingestion, skin and/or eye contact Symptoms: Acne-form dermatitis; liver damage, jaundice Target Organs: Skin, liver (NIOSH, 2016)
Indication of any immediate medical attention and special treatment needed
NAPHTHALENE toxicosis caused by vapor inhalation can usually be managed simply by removing the individual to fresh air. Skin contamination should be removed promptly by washing with soap and water. Eye contamination should be removed by flushing with copious amounts of clear water. Irritation may be severe, and if it persists, should receive medical attention. SRP: /It may be helpful to empty stomach and administer dose of activated charcoal/ Examine the plasma for evidence of hemolysis: a reddish-brown tinge. Examine the blood smear for "ghosts" and Heinz bodies. If /hemolysis is/ present, monitor red blood cell count and hematocrit for anemia, urine for protein, and cells. Measure direct- and indirect-reacting bilirubin in the plasma. Monitor fluid balance and blood electrolytes. If possible, monitor urinary excretion of naphthol to assess severity of poisoning and clinical progress. If hemolysis is clinically significnt, administer intravenous fluids to accelerate urinary excretion of the naphthol metabolite and protect the kidney from products of hemolysis. Use Ringer's-lactate or sodium bicarbonate to keep urine pH above 7.5. Consider use of mannitol, or furosemide, to promote diuresis. If urine flow declines, intravenous infusions must be carefully monitored to avoid fluid overload. Institute hemodialysis. Consider charcoal hemoperfusion in tandem to extract naphthalene and end-products. If anemia is severe, blood transfusions may be needed. Hydrocortisone may be of some benefit if significant hemolysis is present. Fumigant poisoning
Extinguishing media
In case of fire in the surroundings: all extinguishing agents allowed.
Specific Hazards Arising from the Chemical
Literature sources indicate that this chemical is nonflammable. (NTP, 1992)
Advice for firefighters
In case of fire in the surroundings, use appropriate extinguishing media.
Personal precautions, protective equipment and emergency procedures
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. Carefully collect remainder. Then store and dispose of according to local regulations.
Environmental precautions

Methods and materials for containment and cleaning up
First remove all sources of ignition, then dampen the solid spill material with toluene, then transfer the dampened material to a suitable container. Use absorbent paper dampened with toluene to pick up any remaining 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 toluene 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
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
This material should be stored in a refrigerator.

Persistence and degradability
Octachloronaphthalene is reported to have "poor" biodegradability(1). Tetra to hexachlorinated naphthalenes showed no biodegradation during 28 day aerobic biodegradation experiments, although there is some evidence that lower chlorinated forms may biodegrade(2).In addition, a predictive method based upon evaluated biodegradation data and the fact that octachloronaphthalene contains 8 aromatic chlorine substructures predicts that octachloronaphthalene
Bioaccumulative potential
Bioconcentration factor in Oncorhynchus mykiss, exposure concentration 1.3 x 10(-2) ug/L, 330
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for octachloronaphthalene can be estimated to be 1.1X10+5(SRC). According to a classification scheme(2), this estimated Koc value suggests that octachloronaphthalene is expected to be immobile in soil.
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.
