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. See Notes.

In case of skin contact

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

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

4.2 Most important symptoms/effects, acute and delayed

Aldicarb is a carbamate pesticide. It is super toxic; the probable oral lethal dose for humans is less than 5 mg/kg, or a taste (less than 7 drops) for a 150-lb. person. It is extremely toxic by both oral and dermal routes. (EPA, 1998)

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

Symptomatic treatment of the carbamate insecticide-poisoned patient, including aggressive respiratory support & the use of atropine to reverse severe muscarinic manifestations, is the same as with organophosphate insecticide poisoning. Because of the shorter duration of effect, atropine therapy is usually required for <24 hr. The principal difference in therapy for carbamate & organophosphate insecticide exposure involves pralidoxime. 2-PAM is relatively contraindicated in carbamate insecticide poisoning, because it may enhance acetylcholinesterase inactivation. After mixed or combined exposures involving both organophosphate & carbamate insecticides or in severe poisonings with an unidentified anticholinesterase agent, it is reasonable cautiously to administer 2-PAM. /Carbamate insecticides/

5.Fire-fighting measures

5.1 Extinguishing media

Suitable extinguishing media

Move the container of aldicarb from the fire area, if possible, and fight the fire from the maximum distance, using agents suitable for the type of surrounding fire. In case of small fires, use dry chemical powder, carbon dioxide, water spray, or standard foam. For larger fires, use water spray, fog, or standard foam. Thermal decomposition products may include toxic oxides of nitrogen, sulfur, and carbon. Avoid breathing toxic dusts and fumes from burning material.

5.2 Specific hazards arising from the chemical

When heated to decomposition, it emits very toxic fumes of nitrogen oxides and sulfur oxides. Incompatible with highly alkaline substances. Unstable in alkali; poor stability at 122F. (EPA, 1998)

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

Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.

6.2 Environmental precautions

Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

6.3 Methods and materials for containment and cleaning up

In case of spillage during storage or transport, isolate the affected area, cover the spills with a sweeping compound, and post danger signs. Cover the area with suitable sheets, transfer spoiled material in reclaim containers for disposal. Decontaminate the area with 5% sodium hydroxide solution. Use all personal protective devices for handling spills. All tools and equipment should be decontaminated, rinsed, and dried. All clothing should be laundered.

7.Handling and storage

7.1 Precautions for safe handling

Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.

7.2 Conditions for safe storage, including any incompatibilities

Provision to contain effluent from fire extinguishing. Separated from food and feedstuffs.Store aldicarb indoors in an isolated, well-ventilated, clean, dry, cool area (not above 46°C). Store away from incompatible substances, such as highly alkaline materials. Aldicarb should be stored in a manner that will preclude mixing with water, because the resultant solution may be seriously hazardous. Do not store near food, animal feed, or other items intended for human or animal consumption. Make certain that the storage area is inaccessible to children.

12.2 Persistence and degradability

Aldicarb has been extensively studied both in the laboratory under controlled conditions and in the field(1). Under aerobic conditions, it has been shown to oxidize at the sulfur atom to form first the sulfoxide, followed by further oxidation to the sulfone. Under anaerobic conditions, reduction to the corresponding aldehyde and nitrile is the proposed degradation pathway. It has not been definitively shown that these reactions are abiotic or biotic(1). Mineralization half-lives for the aerobic incubation of aldicarb were 20-361 days in surface soils up to 30 cm depth, and 131-233 days (223-1130 days anaerobic) in subsurface soils between 20 and 183 cm in depth(2). Metabolites detected in aerobic soils included aldicarb sulfoxide and sulfone and their oximes and aldicarb sulfoxide nitrile; under anaerobic conditions no aldicarb sulfone or its degradation products were detected(2). Aldicarb did not degrade in sterile or unsterile groundwater under anaerobic conditions in 60-65 days at pH 5.2 and 6.0 or in 40 days in aerated groundwater at pH 7.6 (with or without added sieved limestone)(3). In unfiltered anaerobic groundwater and anaerobic groundwater amended with limestone and filtered with membrane filters to remove microorganisms, the half-lives of aldicarb were 62 and 433 days, respectively(4). Using this same groundwater, but aerated with sterile air under laboratory conditions, the half-life of aldicarb ranged from 34 to 94 days at pH 8.5(4). Aldicarb sulfoxide and aldicarb sulfone degraded more rapidly, with half-lives in the range of 10-47 days (sulfoxide) and 4-32 days (sulfone) under aerobic conditions. Under anaerobic conditions the half-lives ranged from 25-32 days (sulfoxide) and 26-109 days (sulfone)(4). Aldicarb sulfoxide has been shown to be reduced to aldicarb in groundwater under anaerobic conditions in groundwater to which glucose had been added(4). Aldicarb degraded faster in soil which had been previously treated with carbofuran. After 1 day, 68% of aldicarb applied remained in soil not treated with carbofuran, whereas 16% remained in soil treated 4 times with carbofuran between 1-13 weeks prior to treatment with aldicarb. Zero% remained in soil treated once with carbofuran 13 weeks prior to treatment with aldicarb(5).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for aldicarb(SRC), using a log Kow of 1.13(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). Aldicarb had mean log bioconcentration ratios of 0.263 and -0.92 for plant/soil in above and below ground plants, respectively(4).

12.4 Mobility in soil

Koc values for aldicarb have been reported from data in the UK database in 1993 to range from 7 to 80(1). Measured Koc values have also been reported as 30(2) and 32(3). In Valois sand (30.1% sand, 55.2% silt, 14.7% clay, 1.64% organic carbon) the Koc was 22(4). According to a classification scheme(5), these Koc values suggest that aldicarb is expected to have very high to high mobility in soil. Aldicarb and its metabolites are rapidly degraded in soils, which can limit the mobility and leaching potential of these compounds(6-8).

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.
