Rinse mouth. Give a slurry of activated charcoal in water to drink, but NOT if convulsions occur. Refer immediately for medical attention. Rest.

Most important symptoms/effects, acute and delayed

ACUTE/CHRONIC HAZARDS: Carcinogen. Toxic. Irritant. Hazardous decomposition product. (NTP, 1992)

ACUTE/CHRONIC HAZARDS: Highly toxic carcinogen. May cause irritation on contact. Hazardous decomposition products. (NTP, 1992)

ACUTE/CHRONIC HAZARDS: Highly toxic. May cause irritation on contact. Hazardous decomposition products. (NTP, 1992)

Excerpt from ERG Guide 151 [Substances - Toxic (Non-combustible)]: Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. (ERG, 2016)

Lindane is a stimulant of the nervous system, causing violent convulsions that are rapid in onset and generally followed by death or recovery within 24 hours. The probable human oral lethal dose is 50-500 mg/kg, or between 1 teaspoon and 1 ounce for a 150-lb (70 kg) person. (EPA, 1998)

Indication of immediate medical attention and special treatment needed, if necessary

Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary . Anticipate seizures and treat if necessary . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport . Do not use emetics. For ingestion, rinse mouth and administer 5 mL/kg up to 200 mL of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal . Lindane and Related Compounds

SECTION 5: Firefighting measures

Suitable extinguishing media

To extinguish a fire involving this chemical you may use a dry chemical, carbon dioxide, foam or halon extinguisher; a water spray may also be used. (NTP, 1992)

Specific hazards arising from the chemical

Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. For electric vehicles or equipment, ERG Guide 147 (lithium ion batteries) or ERG Guide 138 (sodium batteries) should also be consulted. (ERG, 2016)

Excerpt from ERG Guide 151 [Substances - Toxic (Non-combustible)]: Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways. (ERG, 2016)

When heated to decomposition, this compound emits toxic fumes of chlorine, hydrochloric acid, and phosgene. (EPA, 1998)

Special protective actions for fire-fighters

In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep drums, etc., cool by spraying with water.

SECTION 10: Stability and reactivity

Reactivity

Decomposes on heating and on burning. This produces toxic and corrosive fumes including chlorine (see ICSC 0126), hydrogen chloride (see ICSC 0163) and phosgene (see ICSC 0007). Reacts with bases. This produces toxic and corrosive fumes including hydrogen chloride and trichlorobenzenes (see ICSCs 0344, 1049 and 1222).

Decomposes on contact with hot surfaces or flames. This produces toxic and corrosive fumes including chlorine (see ICSC 0126), hydrogen chloride (see ICSC 0163) and phosgene (see ICSC 0007). Reacts with bases and powdered metals.

Chemical stability

Stable to heat, light, oxidation.

Possibility of hazardous reactions

Not flammable.Halogenated aliphatic compounds, such as ALPHA-BHC, are moderately or very reactive. Halogenated organics generally become less reactive as more of their hydrogen atoms are replaced with halogen atoms. Materials in this group may be incompatible with strong oxidizing and reducing agents. Also, they may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.

Conditions to avoid

no data available

Carcinogenicity

Cancer Classification: Suggestive Evidence of Carcinogenicity, but Not Sufficient to Assess Human Carcinogenic Potential

Reproductive toxicity

Limited information is available regarding the reproductive or developmental effects of lindane in humans. The one available study reported increased levels (not statistically significant) of follicle stimulating hormone and decreased levels of testosterone in men occupationally exposed to lindane. It is not known whether these hormonal changes could result in diminished reproductive capability. Animal studies have reported reproductive effects, such as decreased sperm count, increased testicular weight, and disruption of spermatogenesis from oral exposure to lindane. Disrupted ovarian cycling and reduced ovulation rate were reported in female animals exposed to lindane by gavage (experimentally placing the chemical in the stomach). Lindane has not been reported to cause developmental effects, such as birth defects, in animals via oral exposure.

STOT-single exposure

The substance may cause effects on the central nervous system. The effects may be delayed.

STOT-repeated exposure

Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the nervous system, bone marrow, kidneys and liver. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxic effects upon human reproduction.

Aspiration hazard

A harmful concentration of airborne particles can be reached quickly when dispersed.

SECTION 12: Ecological information

Toxicity to daphnia and other aquatic invertebrates: LC50 Daphnia magna (Water flea) 1.64 mg/L/24 hr (95% confidence limit: 1.15-1.78 mg/L); static
Toxicity to algae: no data available
Toxicity to microorganisms: no data available

Persistence and degradability

Pure cultures of Clostridium sphenoicles metabolizes lindane to gamma-3,4,5,6-tetrachloro-1-cyclohexene. Pure cultures of Escherichia coli metabolizes lindane to gamma-2,3,4,5,6-pentachloro-1-cyclohexene.

Bioaccumulative potential

Penaeus duorarum (decapod) exposed to 0.13-0.62 ug/L of lindane for 96 hrs exhibited a bioaccumulation factor of 32-143. Lagodon rhombides (fish) exposed to 18 to 91 ug/L of lindane for 96 hrs exhibited a bioaccumulation factor range of 167 to 554. Cyprinodon variegatus (fish) exposed to 42 to 109 ug/L of lindane for 96 hr exibited bioaccumulation factors ranging from 337 to 727.

Mobility in soil

Sorption to suspended sediment and biota is not extensive, sorption is an important process for ... transporting lindane to anaerobic sediments where transformation occurs.

Other adverse effects

no data available

SECTION 13: Disposal considerations

Disposal methods

Product

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.

Contaminated packaging

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.
