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.

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)

Skin decontamination. Skin contamination should be treated promptly by washing with soap and water. Contamination of the eyes should be treated immediately by prolonged flushing of the eyes with large amounts of clean water. If dermal or ocular irritation persists, medical attention should be obtained without delay. Other herbicides

If material on fire or involved in fire: Do not extinguish fire unless flow can be stopped or safely confined. 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, carbon dioxide or dry chemical. Triazine pesticides, liquid, NOS

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)

Wear self-contained breathing apparatus for firefighting if necessary.

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.

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.

For minor spills, follow all precautions indicated on this label and clean up immediately. Take special care to avoid contamination of equipment and facilities during cleanup procedures and disposal of wastes. ... Ametryn Technical

Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.

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.

Nonflammable.An amine, organosulfide. Organosulfides are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.

AEROBIC: Several soil bacteria and fungi are reported to attack ametryne(1). The methylthio group is known to undergo sulfoxidation by microsomal enzymes in plant and animal systems and the same reactions usually hold true for soil microorganisms(1). Methylthio-s-triazine herbicides are generally more resistant to biodegradation than the corresponding chloro-s-triazines(1). No biodegradation was observed when 200 ppm of ametryne was incubated for a month using a soil suspension inoculum at 30 deg C(2). When the concn equivalent of 3 kg/ha of ametryne was incubated in a clay-lime soil, 2.8% and 8.6% of the herbicide degraded to CO2 in 51 and 110 days, respectively(2). In another experiment, 10-50% degradation in 10 days occurred in one of four soils, while degradation was either absent or uncertain in the other three soils(3). In a 25-day experiment, CO2 evolution occurred from ametryne-treated sterile soil that had been inoculated with an extract from ametryne enriched soil, but not from uninoculated controls(1). After 60 days incubation, 8.7% and 63.7% of the applied ametryne remained in inoculated Hilo silty clay loam and Molakai silty clay, two Hawaiian soils that are typically used in the cultivation of sugarcane(4). The inoculum was prepared by leaching Molakai soil with ametryne solutions(4). Biodegradation initially involved N-dealkylation. Less than 0.2% of the ametryne degraded to CO2 in this period(4). No significant degradation occurred in autoclaved controls(4). Ametryne has been shown to be susceptible to degradation by Nocardiodes sp.(5).

An estimated BCF of 19 was calculated in fish for ametryne(SRC), using a log Kow of 2.98(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

The average Koc reported for ametryne in 32 soils was 388.4(1). Ametryne has a Koc value of 300(2). Mean overall Koc values measured in four Hawaiian soils were 257 for surface soil (0 to 20 cm) and 170 for subsoil (60 to 80 cm); Kocs of 530, 170, 156, and 171 were measured in the surface soil of Torrox (mean % OC 1.30, pH 6.7), Eustrustox (mean OC 1.63%, pH 6.4), Tropohumult (mean OC% 2.88, pH 5.3), and Hydrandept (mean OC% 6.22, pH 5.3); Kocs of 235, 254, 87, and 107 were measured in subsoil of Torrox (mean OC% 0.55, pH 6.8), Eustrustox (mean OC% 0.76, pH 5.7), Tropohumult (mean OC% 1.51, pH 5.3), and Hydrandept (mean OC% 3.19, pH 5.6)(3). Koc values were measured for two Kishon River sediments; Kfar Yehushua was 69.33 (7.1 pH, 30% sand, 30% silt 40% clay 1.63% TOC) and Haifa industrial area was 170.40 (6.8 pH, 30 % sand, 20% silt, 50% clay, 1.25% TOC)(4). Koc values ranged from 102-123 in fresh soils amended with activated sludge, anaerobic digested sludge and compost, and 69-129 in incubated soils with the same amendments(5). According to a classification scheme(6), these Koc values suggest that ametryne is expected to have moderate to high mobility in soil(SRC). Of 38 values sited in literature the mean Kd is 5.69(7).

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.
