Consult a physician. Show this safety data sheet to the doctor in attendance.
If inhaledIf breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician.
In case of skin contactWash off with soap and plenty of water. Consult a physician.
In case of eye contactRinse thoroughly with plenty of water for at least 15 minutes and consult a physician.
If swallowedNever give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.
4.2 Most important symptoms/effects, acute and delayedno data available
4.3 Indication of immediate medical attention and special treatment needed, if necessaryThe usual measures for gut and skin decontamination are recommended for large doses. Disulfiram-alcohol reactions usually last several hours and respond to fluids, oxygen, and analgesics. Dysrhythmias may develop, and patients with serious reactions should have cardiac monitoring. /Dithio- and thiocarbamates/
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. /Thiocarbamate pesticides, liquid, toxic, flammable; Thiocarbamate pesticides, liquid, flammable, toxic/
5.2 Specific hazards arising from the chemicalno data available
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 precautionsPrevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided.
6.3 Methods and materials for containment and cleaning upEnvironmental considerations: Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Absorb bulk liquid with fly ash, cement powder, or commercial sorbents. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner./ /Thiocarbamate pesticides, liquid, toxic, flammable; Thiocarbamate pesticides, liquid, flammable, toxic; Thiocarbamate pesticides, liquid, 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 incompatibilitiesStore in a cool, dry place. Keep container closed when not in use. Do not store below 32 dg F. Product crystalizes at lower tempratures. Warm or store at higher tempratures and mix to redissolve crystals and assure uniformity before use. /Vapam/
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.

AEROBIC: Sodium methyldithiocarbamate in soil breaks down by chemical means rather than by soil microorganisms(1). Data on the biodegradation of sodium methyldithiocarbamate in aquatic systems were not available(SRC, 2008).
12.3 Bioaccumulative potentialSodium methyldithiocarbamate hydrolyzes rapidly to form methyl isothiocyanate(1) and therefore is unlikely to bioconcentrate in aquatic organisms(SRC).
12.4 Mobility in soilSodium methyldithiocarbamate hydrolyzes rapidly to form methyl isothiocyanate(1) and therefore is unlikely to adsorb or leach(SRC). In soil, this transformation occurs at an extent >90% (following first-order kinetics), corresponding to a half-life of about 0.06 days at 25°C(2). However, a coefficient of adsorption on soil organic matter (Kom) of 228 L/kg has been reported(2).
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 Disposal methods ProductThe 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 packagingContainers 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.
