4.1 Description of necessary first-aid measures
General advice
Consult a physician. Show this safety data sheet to the doctor in attendance.
If inhaled
If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician.
In case of skin contact
Wash off with soap and plenty of water. Consult a physician.

Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.
If swallowed
Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.
4.2 Most important symptoms/effects, acute and delayed
Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: Inhalation of material may be harmful. Contact may cause burns to skin and eyes. Inhalation of Asbestos dust may have a damaging effect on the lungs. Fire may produce irritating, corrosive and/or toxic gases. Some liquids produce vapors that may cause dizziness or suffocation. Runoff from fire control may cause pollution. (ERG, 2016)
4.3 Indication of immediate medical attention and special treatment needed, if necessary
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/
5.Fire-fighting measures
5.1 Extinguishing media
Suitable extinguishing media
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/
5.2 Specific hazards arising from the chemical
Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot. For UN3508, be aware of possible short circuiting as this product is transported in a charged state. (ERG, 2016)
5.3 Special protective actions for fire-fighters
Wear self-contained breathing apparatus for firefighting if necessary.
6.Accidental release measures
6.1 Personal precautions, protective equipment and emergency procedures

10.Stability and reactivity
10.1 Reactivity
no data available
10.2 Chemical stability
Very stable over several yr of shelf life, with only slight sensitivity to natural light & extreme temp which would occur normally.
10.3 Possibility of hazardous reactions
A triazine derivative. 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.

12.2 Persistence and degradability
AEROBIC: It has been reported that the methylthio group of prometryne is oxidized by soil microorganisms to the sulfoxide and sulfone; the sulfone is hydrolyzed to 2,4-bis(isopropylamino)-6-hydroxy-1,3,5-triazine(1). Adaptation and enrichment of viable microbial populations may be necessary for the degradation of methylthio-s-triazines such as prometryne(2). The half-life for degradation of prometryne incorporated into soil under field conditions has been observed to range from nearly 120 days to 145 days(3). Prometryne was shown to degrade, type of degradation not specified, in the field with a half-life of 58 days and in the laboratory experiments with half-lives of 64 days for surface soil (0-25 cm, pH 5.3, 0.53% organic carbon, 98% sand) and 141 days for subsurface soil (25-50 cm, pH 5.5, 0.15% organic carbon, 98% sand)(4). The time required for decomposition of prometryne in soil has been reported as 1 to 6 months; however, whether this refers to total degradation of parent as well as active metabolites is unknown(5). Residual activity of prometryne incorporated into soil at selective rates for specific soil types is from 1-3 months under most normal conditions(6). Half-life for the biodegradation of prometryne in aerobic soil has been reported as 150 days(7). Prometryne was applied at 2 kg a.i./ha along with diazinon, and measurements were made to determine the extent of dissipation in orchard soils(8). Concns dropped from 967 ng/g to 400 ng/g in the 67 day study period(8). Soils received an initial application of prometryne followed by a 4 year aging period. Several more treatments were then given to this soil over a 6 month period(9). After the initial 4 year period, 53.5% of the initial radiolabel was present as bound residues; after the 6 month period of multiple treatments, bound residues decreased to 33.2% while extractable residues increased to 50.9% of the total radiolabel(9). Prometryne has been shown to be susceptible to degradation by Nocardiodes sp.(10).
12.3 Bioaccumulative potential
An estimated BCF of 48 was calculated in fish for prometryne(SRC), using a log Kow of 3.51(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).
12.4 Mobility in soil
Koc values of 300 and 600 were measured for prometryne in soil at a pH of 7 and 5, respectively(1). Koc values of 200, 320, 808, and 1000 were measured in batch adsorption experiments at 10°C using river sediment from 4 different locations on the same river(2). According to a classification scheme(3), these Koc values suggest that prometryne is expected to have slight to very high mobility in soil(SRC).
12.5 Other adverse effects
no data available
13.Disposal considerations
13.1 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.
Contaminated packaging
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.
