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 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
Classified by the World Health Organization as highly hazardous. Has also been rated as extremely to super-toxic. Acute oral exposure (ingestion) to oxamyl has caused death. Oxamyl is a potent cholinesterase inhibitor. (EPA, 1998)
Indication of immediate medical attention and special treatment needed, if necessary
The clinical approach to carbamate toxicity is similar to that for organophosphate poisoning; the major exception is that pralidoxime usually is not recommended. Carbamates
SECTION 5: Firefighting measures
Suitable extinguishing media
This is a solid carbamate pesticide. Move container from fire area. Fight fire from maximum distance. Dike fire control water for later disposal; do not scatter the material. Wear positive pressure breathing apparatus and special protective clothing. Extinguish fire using agent suitable for type of surrounding fire, as the material itself does not burn or burns with difficulty. Use water in flooding quantities as a fog. Use alcohol foam, carbon dioxide or dry chemical. (EPA, 1998)
Specific hazards arising from the chemical
When heated to decomposition, it emits toxic fumes of nitrogen oxides and sulfur oxides. This is a solid carbamate pesticide. Container may explode in heat of fire. (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
If you spill this chemical, you should dampen the solid spill material with water,then transfer the dampened material to a suitable container. Use absorbent paper dampened with water to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Wash all contaminated surfaces with a strong soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

Precautions for safe handling
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
You should protect this material from exposure to light and air, and store it under refrigerated temperatures.

SECTION 10: Stability and reactivity
Reactivity
Decomposes to innocuous materials in natural waters and in soil. Aeration, sunlight, alkalinity, and higher temperatures increase the rate of decomposition. (NTP, 1992)
Chemical stability
Solid and formulations are stable.
Possibility of hazardous reactions
OXAMYL is a carbamate ester. 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.
Conditions to avoid
no data available
Incompatible materials
Incompatible with alkaline materials.
Hazardous decomposition products
Decomposes to innocuous materials in natural waters and soil.

Persistence and degradability
Using loamy sand (pH 6.8) from North Carolina and a sandy soil (pH 6.4) from Florida, half-lives for the degradation of oxamyl were 11 and 15 days, respectively, under aerobic conditions(1). Under anaerobic conditions, a half-life of 6 days was obtained with Keyport silt loam (pH 4.7)(1). The decomposition of oxamyl in soils followed first-order kinetics, the half-life ranging from 4-33 days in a Bet Dagan soil(2). Less than 5% of the oxamyl remained after one day in four water saturated, anaerobic subsoils at 10 deg C(3). Half-lives in aerobic soils ranged from 21 days in loamy fine sand to 415 days in fine sand at 10 deg C(3). Oxamyl in moist soils (Arrendondo sand, Cecil sandy loam, and Genada silt loam) was rapidly mineralized to CO2; mineralization half-lives for 14C oxamyl ranged from 23 to 46 days(4).
Bioaccumulative potential
An estimated BCF of 3.1 was calculated for oxamyl(SRC), using a log Kow of -0.48(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).
Mobility in soil
An experimental study using Arrendondo, Cecil, and Webster soils found Koc values of 8, 6, and 10, respectively(1). According to a classification scheme(2), these Koc values suggest that oxamyl is expected to have very high mobility in soil. Laboratory experiments show that oxamyl is fairly mobile in muck, loamy sand, and 2 silt loam soils (with movement faster in the loamy sand and slowest in the muck)(3). However, field leachate studies in silt loam, loamy sand, and fine sand show that movement is not that extensive even after 3 to 5 months with very little oxamyl below 15 inches(3). This difference may be attributed to oxamyl degradation losses being greater than movement through soil despite large rainfall levels(3).
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.
