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.

In case of eye contact

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

/SRP:/ Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Poisons A and B/

5.Fire-fighting measures

5.1 Extinguishing media

Suitable extinguishing media

Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: SMALL FIRE: Dry chemical, CO2, water spray or regular foam. LARGE FIRE: Water spray, fog or regular foam. Do not scatter spilled material with high-pressure water streams. Move containers from fire area if you can do it without risk. Dike fire-control water for later disposal. FIRE INVOLVING TANKS: 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. (ERG, 2016)

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

12.2 Persistence and degradability

AEROBIC: Using water from two nursery recycling ponds, pendimethalin exhibited first-order half-lives of 26.9-37.4 days at 10°C in non-sterile water and 137.5-183.4 days in sterile water(1); at 22°C, the first-order half-lives were 16.4-29.1 days in non-sterile water and 71.4-121.0 days in sterile water(1). A soil degradation study using an agro-soil from Iowa found virtually no pendimethalin biodegradation over a 160-day period(2); it was thought that pendimethalin desorption from the soil was very difficult resulting in no bioavailablity(2). The persistence of pendimethalin was studied in non-flooded and flooded nonsterile and sterile sandy loam soil (0.35% organic carbon, pH 8.2%) at 30°C over 90 days(3). The degradation was first order with half-lives of 52.2 and 33.4 days in nonsterile nonflooded and flooded soil, respectively, and 66.9 and 44.9 days in sterile nonflooded and flooded soil, respectively(3). Therefore degradation is faster in flooded than in nonflooded soil. While the herbicide was more persistent in nonsterile than sterile soil, only 11-14% of the degradation over 90 days could be attributed to microbial activity. The formation of two major metabolites, N-(1-ethylpropyl)-3,4-dimethyl-2-nitrobenzene-1,6-diamine and 3,4-dimethyl-2,6-dinitroaniline indicate that under aerobic conditions N-dealkylation and reduction of the less hindered nitro groups are primary transformation mechanisms. The same products were formed when pendimethalin was incubated with enriched cultures of soil fungi(4). Under flooded conditions, the sole product was N-(1-ethylpropyl)-5,6-dimethyl-7-nitrobenzimidazole which is formed through the intermediate, 6-aminopendimethalin in the presence of a source of carbon(3). Presumably, the source of carbon is needed to supply the carbon atom on the benzimidazole ring(SRC). Statements were also made by the investigators without any supporting data that complete degradation of pendimethalin in flooded soil could occur in four and even one day, as a result of which short periods of excessive rainfall could cause unexpectedly rapid dissipation of pendimethalin and the formation of alternate degradation products(3). No discussion of possible mechanisms was presented for the comparable amounts of degradation in sterile soil(SRC).

12.3 Bioaccumulative potential

A bioconcentration study using USEPA guideline 165-4 (OPPTS 850.1730), Bluegill fish (Lepomis macrochirus) and a 28-day exposure period determined a pendimethalin BCF value of 5,100(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is very high(SRC). 14C-Pendimethalin-treated soil (1 and 10 ppm) was added to a model ecosystem containing 16 L of water 400 g of soil, snails, fish, algae, and daphnids and monitoring over 30 days(3); snails reached their peak 14C level between days 7 and 15; while 50% of the radioactivity was pendimethalin on day-1, <1% was so by day-15; fish reached their peak 14C level on day-1 and thereafter levels declined paralleling that of 14C in water; while 76% of the radioactivity was pendimethalin on day-1, this decreased to 22% by day-30; these data suggest that fish preferentially accumulated pendimethalin over more polar metabolites and degraded it more slowly than snails; algae accumulated 14C slowly over the 30-day experiment and daphnia reached a 14C plateau between day-7 and day-15, but this depurated within 10 days in fresh water; the maximum 14C BCF (as pendimethalin) ranged from 190 (algae) to 312 (fish)(3). The BCF of pendimethalin in a sea nettle (Chrysaora quinquecirrha) was 0.42 after 16 hrs(4).

12.4 Mobility in soil

Batch equilibrium adsorption tests using nine different soils (organic carbon ranging from 0.44% to 2.91%) determined pendimethalin Koc values ranging from 7,011-43,863(1). Koc values in five different soils ranged from 6,500-29,400 with a median/recommended Koc value of 13,400(2). According to a classification scheme(3), these Koc values suggest that pendimethalin is expected to be immobile in soil. A four year field study in a sandy loam soil from 2003-2007 found no pendimethalin detected below a 10 cm soil depth(4). A field study in turfgrass land of loamy sand soil observed a low runoff and leaching of applied pendimethalin(5); runoff was highest following the first rainfall and decreased exponentially thereafter(5). Koc values of 10,200 and 22,000 were observed using two sediments from a nursery recycling pond(6).

12.5 Other adverse effects

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.
