Commercial formulations are granular Used as an insecticide, acaricide, and nematocide. <br />(EPA, 1998) <br />Fire Hazard <br />When heated to decomposition, it emits very toxic fumes of nitrogen oxides and sulfur oxides. Incompatible with highly alkaline substances. <br />Unstable in alkali; poor stability at 122F. (EPA, 1998) <br />Fire Fighting <br />(Non -Specific -- Carbamate Pesticide, Solid) Stay upwind; keep out of low areas. Ventilate closed spaces before entering them. Wear <br />positive pressure breathing apparatus and special protective clothing. Move container from fire area if you can do it without risk. Fight fire <br />from maximum distance. Dike fire control water for later disposal; do not scatter the material. <br />(Non -Specific -- Carbamate Pesticide, Solid) Some of these materials may burn but none of them ignite readily. Small fires: dry chemical, <br />carbon dioxide, water spray, or foam. Large fires: water spray, fog or foam. (EPA, 1998) <br />Protective Clothing <br />For emergency situations, wear a positive pressure, pressure -demand, full facepiece self-contained breathing apparatus (SCBA) or <br />pressure- demand supplied air respirator with escape SCBA and a fully -encapsulating, chemical resistant suit. (EPA, 1998) <br />Non -Fire Response <br />Caution : Avoid sources of heat including fire. Aldicarb will liberate toxic nitrogen and sulfur oxide gases when heated. <br />(Non -Specific -- Carbamate Pesticide, solid) Keep unnecessary people away; isolate hazard area and deny entry. Stay upwind; keep out of <br />low areas. Ventilate closed spaces before entering them. Remove and isolate contaminated clothing at the site. Do not touch spilled <br />material; stop leak if you can do it without risk. Use water spray to reduce vapors. <br />Small spills: take up with sand or other noncombustible absorbent material and place into containers for later disposal. <br />Small dry spills: with clean shovel place material into clean, dry container and cover; move containers from spill area. <br />Large spills: dike far ahead of spill for later disposal. (EPA, 1998) <br />Health Hazard <br />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 <br />drops) for a 150 -Ib. person. It is extremely toxic by both oral and dermal routes. (EPA, 1998) <br />Properties <br />Melting Point: 210 to 214° F (EPA, 1998) <br />Vapor Pressure: Less than 0.5 at 68F (EPA, 1998) <br />Boiling Point: Decomposes (NTP, 1992) <br />Molecular Weight: 190.23 (EPA, 1998) <br />TEEL1: 0.21 mg/m3 (TEEL, 2003) <br />TEEL2: 0.3 mg/m3 (TEEL, 2003) <br />TEEL3: 0.3 mg/m3 (TEEL, 2003) <br />Water Solubility: 0.1-1.0 mg/mL at 72° F (NTP, 1992) <br />6/12/2007 Printed from CAMEO Page 1 <br />
