Most important symptoms and effects, both acute and delayed

ACUTE/CHRONIC HAZARDS: Highly toxic by ingestion, inhalation, and skin absorption. (NTP, 1992)

It is very toxic. The probable oral lethal dose is 50 to 500 mg/kg, or 1 teaspoonful to 1 ounce for a 150 lb. person. (EPA, 1998)

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)

Indication of any immediate medical attention and special treatment needed

Observation. Persons exposed to high levels of organochlorine pesticides by any route should be observed for sensory disturbances, incoordination, speech slurring, mental aberrations, and involuntary motor activity that would warn of imminent convulsions. Solid organochlorine insecticides

SECTION 5: Firefighting measures

Extinguishing media

If material involved in fire: Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use "alcohol" foam, dry chemical, or carbon dioxide. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Keep run-off watter out of sewers and water sources. Endosulfan (organochlorine pesticides, liquid, toxic); Endosulfan (organochlorine pesticides, solid, toxic)

Specific Hazards Arising from the Chemical

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)

Container may explode in heat of fire. Fire or run off from fire control water may release irritating or poisonous gases. Slowly oxidizes in air. Do not store at temperature below 20F. (EPA, 1998)

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)

Advice for firefighters

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

SECTION 6: Accidental release measures

Personal precautions, protective equipment and emergency procedures

Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT wash away into sewer. Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

Environmental precautions

Do NOT wash away into sewer. Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. Personal protection: chemical protection suit including self-contained breathing apparatus.

Methods and materials for containment and cleaning up

SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a POTW is acceptable only after review by the governing authority. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must meet Hazardous Material Criteria for disposal.

Toxicity

  • Toxicity to fish: LC50; Species: Danio rerio (Zebra danio, adult, length 3.5 cm, weight 0.18 g); Conditions: freshwater, renewal, 25 deg C, pH 7.1, hardness 35 mg/L CaCO3, dissolved oxygen 5.1 mg/L; Concentration: 1.6 ug/L for 24 hr (95% confidence interval: 1.3-2.1 ug/L) /97% purity mixture of Alpha
  • Toxicity to daphnia and other aquatic invertebrates: EC50; Species: Daphnia magna (Water flea, age <24 hr neonate); Conditions: freshwater, static, 25 deg C; Concentration: 166.44 ug/L for 5 hr (95% confidence interval: 138.25-218.66 ug/L); Effect: decreased food consumption

Persistence and degradability

Degradation of endosulfan by soil microorganism of family pseudomonas was studied. the alcohol was main metabolite from either isomer, beta-isomer also yielded small amt of endosulfan ether as well as isomerized to more stable alpha-isomer ...

Bioaccumulative potential

A measured BCF of 2,650 was obtained for zebra fish exposed to 0.3 ug/L of endosulfan for 21 days in a flow-through aquarium(1). A BCF value of 11,583 was measured for endosulfan in yellow tetra fish exposed to 0.3 ug/L of endosulfan for 21 days in a flow-through aquarium(2). It was noted in both sets of experiments that endosulfan depuration by fish was rapid, with approximately 81% total endosulfan elimination within 120 hours when the fish were placed in a tank of pure water containing no endosulfan(1,2). According to a classification scheme(3), this BCF data suggests the potential for bioconcentration in aquatic organisms is very high, provided the compound is not metabolized by the organism(SRC).

Mobility in soil

Koc values from 350 to 1,135, and of 2,000 were reported for endosulfan in soil(1,2). The Koc of alpha-endosulfan in marine sediment was measured as 3,981 and the Koc for beta-endosulfan was measured as 19,953(3). According to a classification scheme(4), these Koc values suggests that endosulfan is expected to be moderately mobile to immobile in soil.

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.
