Consult a physician. Show this safety data sheet to the doctor in attendance.
If inhaledFresh air, rest. Refer immediately for medical attention.
In case of skin contactRemove contaminated clothes. Rinse and then wash skin with water and soap. Refer immediately for medical attention.
In case of eye contactRinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention.
If swallowedRinse mouth. Refer immediately for medical attention. Give a slurry of activated charcoal in water to drink.
4.2 Most important symptoms/effects, acute and delayedThis material may be fatal if swallowed, inhaled, or absorbed through the skin. Repeated inhalation or skin contact may progressively increase susceptibility to poisoning. (EPA, 1998)
4.3 Indication of immediate medical attention and special treatment needed, if necessaryAirway protection. Ensure that a clear airway exists. Intubate the patients and aspirate the secretions with a large-bore suction device if necessary. Administer oxygen by mechanically assisted pulmonary ventilation if respiration is depressed. Improve tissue oxygenation as much as possible before administering atropine, so as to minimize the risk of ventricular fibrillation. In severe poisonings, it may be necessary to support pulmonary ventilation mechanically for several days. /Organophosphate pesticides/
5.Fire-fighting measures 5.1 Extinguishing media Suitable extinguishing mediaIf material on fire or involved in fire: Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use "alcohol" foam, dry chemical or carbon dioxide. /Organophosphorus pesticides, liquid, flammable, toxic; Organophosphorus pesticides, liquid, toxic/
5.2 Specific hazards arising from the chemicalThis is a liquid organophosphorus pesticide. Fire may produce irritating or poisonous gases. Hydrolyzes under alkaline conditions. (EPA, 1998)
5.3 Special protective actions for fire-fightersWear self-contained breathing apparatus for firefighting if necessary.
6.Accidental release measures 6.1 Personal precautions, protective equipment and emergency proceduresUse personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.
6.2 Environmental precautionsPersonal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Collect leaking liquid in covered containers. Then store and dispose of according to local regulations.
6.3 Methods and materials for containment and cleaning upEnvironmental considerations: Air spill: Apply water spray or mist to knock down vapors. /Organophosphorus pesticides, liquid, flammable, toxic; Organophosphorus pesticides, liquid, toxic; Organophosphorus pesticides, solid, toxic/
7.Handling and storage 7.1 Precautions for safe handlingAvoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.
7.2 Conditions for safe storage, including any incompatibilitiesSeparated from food and feedstuffs and oxidizing materials. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing.You should store this chemical in a freezer and away from all mineral acids and bases.
8.Exposure controls/personal protection 8.1 Control parameters Occupational Exposure limit valuesno data available
Biological limit valuesno data available
8.2 Appropriate engineering controlsHandle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.
8.3 Individual protection measures, such as personal protective equipment (PPE) Eye/face protectionSafety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin protectionWear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
Respiratory protectionWear dust mask when handling large quantities.

Soils from two sites in MO planted with corn and treated at different times with terbufos and other pesticides were examined for microbial populations and efficacy of residual insecticide treatment on ten day old house crickets, Acheta domesticus. ... Soil bacteria counts correlated well ... with the biological persistence of the cricket bioassay. ... Actinomycetes dominated the relationships of various degradation bioassay curves.
12.3 Bioaccumulative potentialAn estimated BCF of 560 was calculated for terbufos(SRC), using a log Kow of 4.48(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC).
12.4 Mobility in soilKoc values ranging from 500 to 5000 have been reported for terbufos(1-4). According to a classification scheme(5), these Koc values suggest that terbufos is expected to have low to slight mobility in soil.
