SECTION 4: First aid measures
Description of necessary first-aid measures
Move the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.
Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.
Rinse with pure water for at least 15 minutes. Consult a doctor.
Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Most important symptoms/effects, acute and delayed
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 immediate medical attention and special treatment needed, if necessary
The clinical approach to carbamate toxicity is similar to that for organophosphate poisoning; the major exception is that pralidoxime usually is not recommended.
SECTION 5: Firefighting measures
Suitable extinguishing media
Excerpt from ERG Guide 151 [Substances - Toxic (Non-combustible)]: SMALL FIRE: Dry chemical, CO2 or water spray. LARGE FIRE: Water spray, fog or regular foam. Move containers from fire area if you can do it without risk. Dike fire-control water for later disposal; do not scatter the material. Use water spray or fog; do not use straight streams. FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn. (ERG, 2016)
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)
Special protective actions for fire-fighters
Wear self-contained breathing apparatus for firefighting if necessary.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.
Environmental precautions
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
Methods and materials for containment and cleaning up
Spillages of pesticides at any stage of their storage or handling should be treated with great care. Liquid formulations may be reduced to solid phase by evaporation. Dry sweeping of solids is always hazardous: These should be removed by vacuum cleaning or by dissolving them in water or other solvent in the factory environment. Pesticides
SECTION 7: Handling and storage
Precautions for safe handling
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Rooms used for storage only should be soundly constructed and fitted with secure locks. Floors should be kept clear and the pesticides clearly identified. Pesticides

Appropriate engineering controls
Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Individual protection measures, such as personal protective equipment (PPE)
Wear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).
Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. 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.
If the exposure limits are exceeded, irritation or other symptoms are experienced, use a full-face respirator.

SECTION 10: Stability and reactivity
Reactivity
Thio and dithiocarbamates slowly decompose in aqueous solution to form carbon disulfide and methylamine or other amines. Such decompositions are accelerated by acids.
Chemical stability
Indefinitely stable; not sensitive to light or heat
Possibility of hazardous reactions
NonflammableDIALLATE is a thiocarbamate ester. Flammable gases are generated by the combination of thiocarbamates and dithiocarbamates with aldehydes, nitrides, and hydrides. Thiocarbamates and dithiocarbamates are incompatible with acids, peroxides, and acid halides.
Conditions to avoid
no data available
Incompatible materials
no data available
Hazardous decomposition products
When heated to decomposition it emits very toxic fumes of /hydrogen chloride, nitrogen oxides and sulfer oxides/.

SECTION 12: Ecological information
Toxicity
- Toxicity to fish: no data available
- Toxicity to daphnia and other aquatic invertebrates: no data available
- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
Persistence and degradability
The half-lives of diallate applied to various agricultural soils range from 2-6 wk(1-3). The principal loss mechanism is biodegradation; while the half-life in four microbially active agricultural soils was 4 wk, it was 20 wk when the soil was sterilized(3). Both isomers biodegrade at similar rates and the only volatile degradation product is carbon dioxide(4).
Bioaccumulative potential
The log BCF calculated for diallate is 2.1(1), which indicates only moderate bioconcentration in fish.
Mobility in soil
The measured value for Koc for diallate is 1900(1). Another investigator measured the Freundlich adsorption isotherms for diallate to five Saskatchewan soils. The values of the Freundlich constant, k, and exponent, 1/n, were (soil organic matter, pH; k, 1/n): Melfort loam (10.5%, 5.9, 56, 0.72), Weyburn sandy loam (6.5%, 6.5; 11, 0.97), Regina clay (4.2%, 77; 9, 0.95), Indian Head sandy loam (4.1%, 7.8; 7, 0.98), and Asquith loamy sand (1.8%, 7.5; 5, 1.03)(4). Assuming a conversion factor of 1.724% organic carbon per percent organic matter, the respective values of Koc of the five soils are 920, 280, 391, 307, and 448, respectively(4). The leaching of diallate and other thiocarbamate herbicide, in soil was shown to be proportional to its solubility in water and inversely proportional to the amount of organic matter in the soil(2). When surface applications of diallate were applied to 5 soils contained in 55 cm columns, the soil wetted to field capacity and the depth of leaching determined 48 hr later, it was found that the diallate leached to 15 cm in washed sand, remained in the top 5 cm in a peaty muck and penetrated to 5-10 cm in three other soils(2). Diallate applied to the test field plots remained in the top 5 cm of soil(3).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.
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.
