Hazards and Protection.
Store at in a clean, dry, and well-ventilated area.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Wear long-sleeved clothing and protective gloves when handling. Wear appropriate chemical protective clothing, gloves, boots and goggles.
Wear positive pressure self-contained breathing apparatus (SCBA).
Caution : Avoid sources of heat including fire. Aldicarb will liberate toxic nitrogen and sulfur oxide gases when heated. (Non-Specific -- Carbamate Pesticide, solid) Keep unnecessary people away; isolate hazard area and deny entry. Stay upwind; keep out of low areas. Ventilate closed spaces before entering them. Remove and isolate contaminated clothing at the site. Do not touch spilled material; stop leak if you can do it without risk. Use water spray to reduce vapors. Small spills: take up with sand or other noncombustible absorbent material and place into containers for later disposal. Small dry spills: with clean shovel place material into clean, dry container and cover; move containers from spill area. Large spills: dike far ahead of spill for later disposal.
Poor stability at 50 C; unstable in alkali analysis. Indicated that this material had not changed under storage conditions for approx 4 years.
Incompatible with highly alkaline substances.
When heated to decomposition, aldicarb emits very toxic fumes of nitrogen oxides and sulfur oxides.
(Non-Specific -- Carbamate Pesticide, Solid) Stay upwind; keep out of low areas. Ventilate closed spaces before entering them. Wear positive pressure breathing apparatus and special protective clothing. Move container from fire area if you can do it without risk. Fight fire from maximum distance. Dike fire control water for later disposal; do not scatter the material.(Non-Specific -- Carbamate Pesticide, Solid) Some of these materials may burn but none of them ignite readily. Small fires: dry chemical, carbon dioxide, water spray, or foam. Large fires: water spray, fog or foam.
Aldicarb is non-flammable and is difficult to ignite, but it may burn.
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.
Fire may produce irritating, corrosive and/or toxic gases.
Rapid breathing may occur. Headache, blurred vision, miosis, tremor, muscle twitching, seizures, mental confusion, and coma may occur. Delayed peripheral neuropathy similar to that seen with organophosphates has been described in one case. Dystonic reaction may occur following parenteral injection. Aldicarb was not teratogenic in rats or rabbits, but fetal rats were more sensitive to cholinesterase inhibition in the brain than the dams. Two stillbirths occurred after pregnant women consumed aldicarb-contaminated watermelons.
Nausea, vomiting, diarrhea, and abdominal cramping may be noted.
Dyspnea, rales, bronchoconstriction and pulmonary edema may occur.
Diaphoresis may be seen.
Pinpoint pupils, tearing and excessive salivation may be seen.
Seek medical assistance.
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult.
Remove contaminated clothing and jewelry. Wash the skin, including hair and nails, vigorously; do repeated soap washings. Discard contaminated clothing.
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
