Mammalian toxicity:
Acute oral LD50: >5000 mg/kg (rat), [For comparison table salt is 3000 mg/kg].
Acute dermal LD50: >2000 mg/kg (rabbit).
Skin: Brief contact may cause slight skin irritation with local redness.

Repeated exposure may cause irritation, even a burn.

May cause drying and flaking of the skin.

May cause corneal injury.

Vapour may cause eye irritation experienced as mild discomfort and redness.
Vapour inhalation: LC50 >5.63 mg/L air (rat).
Excessive exposure may cause irritation to upper respiratory tract (nose and throat) and lungs. Symptoms of excessive exposure may be anaesthetic or narcotic effects; dizziness and drowsiness may be observed.
Specific Target Organ Systemic Toxicity (Repeated Exposure): In animals, effects have been reported on the kidney, liver, gall bladder, gastrointestinal tract, urinary tract, thyroid and lung at high doses.
Suspected of causing cancer due to naphthalene, an ingredient in the hydrocarbon solvent.

25 TOXICITY SYMPTOMS:

26 FIRST AID:

If SWALLOWED: Contact the Poisons Information Centre on 131126 immediately. May be fatal if swallowed and enters airways. Do NOT induce vomiting. Wash out mouth with water. Do NOT give anything by mouth to a semiconscious or unconscious patient. Ingestion of naphthalene by humans has caused hemolytic anemia.
If in EYES: Hold eyelids open and wash eyes with plenty of water for 5 minutes, remove contact lenses if present and wash for a further 10 minutes. May cause serious eye irritation which may be slow to heal. May cause corneal injury. Vapour may cause eye irritation experienced as mild discomfort and redness.See a doctor if symptoms persist.
If on SKIN: Remove contaminated clothing. Wash skin thoroughly with soap and water. Brief contact may cause slight skin irritation with local redness.

Repeated exposure may cause irritation, even a burn.

May cause drying and flaking of the skin.
If INHALED: Remove patient to fresh air. If person is not breathing, call an emergency responder or ambulance, then give artificial respiration; if by mouth to mouth use rescuer protection (pocket mask etc). Call a poison information centre or doctor for treatment advice. If breathing is difficult, oxygen should be administered by qualified personnel.
Maintain adequate ventilation and oxygenation of the patient. May cause asthma-like (reactive airways) symptoms. Bronchodilators, expectorants, antitussives and corticosteroids may be of help. The decision of whether to induce vomiting or not should be made by a physician. If lavage is performed, suggest endotracheal and/or esophageal control. Danger from lung aspiration must be weighed against toxicity when considering emptying the stomach. If hemolysis is suspected, monitor hemoglobin, hematocrit, plasma free hemoglobin, and urinalysis. Whole blood or packed RBC transfusion may be required in severe cases. Alkalinization of urine with bicarbonate may prevent renal damage. No specific antidote. Treatment of exposure should be directed at the control of symptoms and the clinical condition of the patient. Have the Safety Data Sheet, and if available, the product container or label with you when calling a poison information centre or doctor, or going for treatment. Skin contact may aggravate pre-existing dermatitis. Repeated excessive exposure may aggravate pre-existing lung disease. See a doctor if symptoms persist.

Advice to doctor: Symptoms of excessive exposure may be anaesthetic or narcotic effects; dizziness, drowsiness, headache, confusion, sweating, nausea and/or vomiting may be observed. Treat symptomatically.
Contact the Poisons Information Centre on 131126.
