Hazards and Protection.
Storage location should be close to laboratory where it is to be used, so that only small amounts need to be transported. Carcinogens should be kept in only one section of storage area, explosion-proof refrigerator or freezer as required. The area should be appropriately labeled. An inventory should be kept showing the quantity of carcinogen and date it was acquired. Facilities for dispensing should be contiguous to storage area.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Dispensers of liquid detergent should be available. In the laboratory, gloves and protective clothing should always be worn but should not be assumed to provide full protection. Carefully fitted masks or respirators may be necessary when working with particulates or gases, and disposable plastic aprons might provide additional protection. Protective clothing should be of distinctive color, as a reminder not to be worn outside the laboratory.
Wear positive pressure self-contained breathing apparatus (SCBA).
Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Cover with plastic sheet to prevent spreading. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS.
Stable to light, heat, air, carbon dioxide and strong acids.
Incompatible with strong oxidizing and reducing agents Incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.
When heated to decomposition it emits highly toxic fumes of phosgene and hydrogen chloride.
Use method most appropriate to fight surrounding fire.
Toxic gases are generated when solid is heated or when soln burns.
TLV (as gamma-isomer): ppm; 0.5 mg/m3 (skin) (ACGIH 1991-1992).

Elevated body temperature and respiratory depression may occur with prolonged seizures. Abnormally low blood pressure may occur with severe poisoning. Central nervous system excitation, agitation, nervousness, tremor, seizures, sensory disturbances, and peripheral neuropathy may occur. Lindane did not have reproductive effects in a 3-generation rat study. It has not been teratogenic in animals. It disturbed the estrus cycle and reduced fertility in female rats. It has been detected in human breast milk. It produced degenerative changes in the testes of rats.
Nausea, vomiting, diarrhea, hypersalivation, and pancreatitis may occur following ingestion.
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Effects of contact or inhalation may be delayed.
Extensive contact may result in dermatitis, irritation, and local hypersensitivity.
Lindane can irritate the eyes, nose, and throat.
Seek medical assistance.
Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
Remove all exposed clothing and jewelry taking necessary precautions to prevent secondary exposure to health care providers. Irrigate exposed areas promptly with copious amounts of water for at least 30 minutes. Wash the skin, including hair and nails, vigorously; do repeated soap washings. Discard contaminated clothing.
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility. Remove contaminated clothing and jewelry. Wash the skin, including hair and nails, vigorously; do repeated soap washings. Discard contaminated clothing. Carefully observe patient for development of clinical signs and symptoms, and administer treatment as described in dermal exposure where appropriate.
