Description of necessary first-aid measures
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.
Most important symptoms/effects, acute and delayed
Extremely toxic: probable oral lethal dose for humans is 5-50 mg/kg; between 7 drops and 1 teaspoonful for 70 kg person (150 lb.). (Non-Specific -- Carbamate Pesticide, Solid, n.o.s.) Poisonous; may be fatal if inhaled, swallowed, or absorbed through skin. Contact may cause burns to skin and eyes. (EPA, 1998)
Indication of immediate medical attention and special treatment needed, if necessary
Zectran was fed to dogs for 1 wk using (14)c ring-labeled material. 3/4 of excreted radioactivity was found in urine & 1/4 in feces, & in urine 86% of it was as glucuronide or sulfate of corresponding phenol with about 5% of hydroquinone & about 2% of unconjugated phenol being formed.
SECTION 5: Firefighting measures
Suitable extinguishing media
If material /is/ on fire or involved in /a/ fire do not extinguish fire unless flow can be stopped. 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, dry chemical or carbon dioxide. Carbamate pesticide, liquid, nos, (compounds and preparations) (agricultural insecticides, nec, liquid); Carbamate pesticide, liquid, nos (compounds and preparations) (agricultural insecticides, nec, liquid); Carbamate pesticide, liquid, nos (compounds and preparations) (insecticides, other than agricultural, nec
Specific hazards arising from the chemical
Non-Specific -- Carbamate Pesticide, Solid, n.o.s.) Fire may produce irritating or poisonous gases. This material may burn but does not ignite readily. Container may explode in heat of fire. When heated to decomposition it emits toxic fumes of nitrogen oxides. Avoid decomposition in highly alkaline media. Subject to photo-decomposition in the solid state. (EPA, 1998)
Special protective actions for fire-fighters
Wear self-contained breathing apparatus for firefighting if necessary.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
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.
Environmental precautions
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.
Methods and materials for containment and cleaning up
A system for removing pesticides from the wash water produced by pesticide applicators as they clean their equipment has been developed. The first step is the flocculation/coagulation and sedimentation of the pesticide-contaminated wash water. The supernatant from the first step is then passed through activated carbon columns.

Chemical stability
Stable under normal conditions, decomp in highly alkaline media
Possibility of hazardous reactions
MEXACARBATE is a carbamate ester-amine. Amines behave as chemical bases. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.

Persistence and degradability
Mexacarbate biodegraded in soil under unspecified conditions to yield 4-methylamino-3,5-xylyl methylcarbamate, 2,6-dimethylhydroquinone and 4-dimethylamino-3,5-xylenol(1). Pure cultures of HF-3 (a bacterium) and the fungus, Trichoderma viride, are capable of degrading mexacarbate to the major metabolites, 4-dimethylamino-3,5-xylenol and 4-methylamino-3,5-xylyl methylcarbamate(2). Degradation of 14-C labeled mexacarbate was studied in sterile and nonsterile sand loam and clay loam forest soil litters under aerobic and submerged conditions(3). The half-lives for 14-C02 evolution in the nonsterile sandy loam and clay loam litters ranged were 7.31 and 8.88 days, respectively, under aerobic conditions and 7.72 and 9.32, respectively, under submerged conditions(3). Only 1-4% 14-Co2 was evolved in experiments with the autoclaved (sterile) soil litters(3). The recovery of free or loosely bound mexacarbate after 45 days of incubation ranged from 1-2% under aerobic conditions and 8-11% under submerged conditions in nonsterile soil; the recovery from sterile soil ranged from 46-50% under aerobic conditions and 30-38% under submerged conditions(3). These results indicate that the litter microbes contributed to the degradation of mexacarbate and the release of 14-C02(3). Degradation products included desmethylated carbamates, various xylenols, polar, and unknown products(3).
Bioaccumulative potential
Direct introduction of mexacarbate into water resulted in a BCF value of 14 in shrimp and exposure of the shrimp and silverside fish to mexacarbate on sand gave BCF values of 18 and 45, respectively(1). Using a reported water solubility of 100 ppm(2), a BCF of 46 was calculated(3,SRC). Based on the observed and estimated BCF, mexacarbate will not be expected to bioconcentrate in aquatic organisms(SRC).
Mobility in soil
Errors in analysis of the insecticide zectran in natural waters have been attributed to particulate matter in these waters. zectran does sorb onto particulates, according to the amount of organic matter measured as chemically oxidizable carbon.
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.
