4.First-aid measures

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

Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.

In case of skin contact

Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .

In case of eye contact

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

If swallowed

Rinse mouth. Give a slurry of activated charcoal in water to drink. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention .

4.2 Most important symptoms/effects, acute and delayed

LIQUID: POISONOUS IF SWALLOWED. Irritating to skin and eyes. (USCG, 1999)

4.3 Indication of immediate medical attention and special treatment needed, if necessary

Airway protection. Insure that a clear airway exists. Intubate the patients and aspirate the secretions with a large-bore suction device if necessary. Administer oxygen by mechanically assisted pulmonary ventilation if respiration is depressed. Improve tissue oxygenation as much as possible before administering atropine, so as to minimize the risk of ventricular fibrillation. In severe poisonings, it may be necessary to support pulmonary ventilation mechanically for several days. /Organophosphate pesticides/

9.Physical and chemical properties

10.Stability and reactivity

10.1 Reactivity

no data available

10.2 Chemical stability

More stable in alkaline formulations, then when at neutral or acid pH.

10.3 Possibility of hazardous reactions

PRACTICALLY NONFLAMMABLE.Organothiophosphates, such as DIAZINON, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides. POISONOUS GASES ARE PRODUCED WHEN HEATED. Oxides of sulfur and of phosphorus are generated in fires (USCG, 1999). DIAZINON is incompatible with the following: Strong acids & alkalis, copper-containing compounds [Note: Hydrolyzes slowly in water & dilute acid.] (NIOSH, 2016).

10.4 Conditions to avoid

• Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Half-lives reported for diazinon in sterile (non-sterile) soils were 12.5 weeks (<1 week) in sandy loam and 6.5 weeks (2 weeks) in organic soil(1). Diazinon disappeared more quickly from unsterilized natural water (12 weeks) than from unsterilized distilled or sterilized natural water (>16 weeks), suggesting that degradation is both biological and chemical in nature in natural waters(2). Percent theoretical biological oxygen demand (BOD) was 16% for diazinon incubated with municipal sewage for 7.5-8.3 days(3). Diazinon, present at 100 mg/L, reached 0% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(4).

12.3 Bioaccumulative potential

BCF values were measured in the following species: topmouth gudgeon (Pseudodorasbora parva), 152, silver crucian carp (Cyprinus auratus), 36.6, carp (Cryprinus carpio), 65.1, guppy (Lebisters reticuatus) 17.5, crayfish (Procambarus clarkii), 4.9, red snail (Indoplanorbis exustus), 17.0, pond snail (Cipangopoludina malleata), 5.9(1); a fish (Fundulus heteroclutus), 10(2); species unreported, 35(3); carp, 120, rainbow trout, 63, loach, 26, shrimp, 3(4); sheepshead minnow, 200(5); eel(Anguilla anguilla) muscle and liver, 1600 and 800, respectively(6); perch 27(7); earthworm 8(8); fish from the Philipines, 12(9). According to a classification scheme(10), the range of experimental BCFs suggests the potential for bioconcentration in aquatic organisms is low to moderate(SRC).

12.4 Mobility in soil

The Koc for diazinon ranged from 40-432, and averaged 191 for 3 soils(1); in one sediment, the Koc was 250(1). For sandy loam(2.0% OM, pH 5.4), silt loam(1.4% OM, pH 7.0), silt loam(1.8% OM, pH 6.5) and sand(1.4% OM, pH 7.0), the Kocs were 1,539, 1,007, 1,653, and 1,842, respectively, with a recommended value of 1520(2). The Koc for diazinon was found to be 1589 in an Hungarian brown forest soil(3). The Koc for diazinon in two New Zealand topsoils was 165.22 and 324.49(4); the Koc in a New Zealand subsoil was 1447.47(4). According to a classification scheme(5), these experimental Koc values suggest that diazinon is expected to have moderate to low mobility in soil(SRC). Diazinon was given a leaching index of 2.0 (<20 cm movement/yr with 150 cm of annual rainfall)(6). Diazinon is reported to be fairly strongly adsorbed onto soil with low mobility(7).

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.
