Hazards and Protection.
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
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.
Protective clothing should be worn when working with the undiluted preparation.
Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
(Non-Specific -- Carbamate Pesticide, Solid, n.o.s.) Keep unnecessary people away; isolate hazard area and deny entry. Stay upwind, keep out of low areas. Do not touch spilled material, or breathe the vapors, dusts, or fumes from burning materials. Do not handle broken packages without protective equipment. Wash away any material that may have contacted the body with soap and water.
Volatility of 1 mgcu m technical hydrolyzed by acid and alkali.
Incompatible with strong acids and bases, and especially
(Non-Specific -- Carbamate Pesticide, Solid, n.o.s.) 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.(Non-Specific -- Carbamates) Extinguish fire using agent suitable for types of surrounding fire, as the material itself burns with difficulty. Use water in flooding quantities as a fog. Use alcohol foam, carbon dioxide, or dry chemical.
Moderate; liquid formulations may be flammable if they contain a flammable solvent. The technical material may burn, but is difficult to ignite.
Rapid breathing may occur following inhalation of carbamate dusting powders, but is not necessarily related to severity of ensuing symptoms. Blurred vision, miosis, tremor, muscle twitching, convulsions, mental confusion, and coma may occur. Delayed peripheral neuropathy similar to that seen with organophosphates has been described in one case. Protracted malaise and weakness may occur after apparent recovery from carbamate poisoning. No data were available to assess the teratogenic potential of this agent. <br>No data were available to assess the potential effects of exposure to this agent during pregnancy or lactation.
Nausea, vomiting, diarrhea, and abdominal cramping may be noted.
Dyspnea, rales, and pulmonary edema may occur.
Diaphoresis may be noted. Dimetilan was not irritating to the skin of rats.
Pinpoint pupils, tearing, and excessive salivation may be seen.
Do not induce emesis. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
If symptoms develop, move individual away from exposure and into fresh air. If symptoms persist, seek medical attention. If breathing is difficult, administer oxygen. Keep person warm and quiet; seek immediate medical attention.
Remove contaminated clothing and jewelry. Wash the skin, including hair and nails, vigorously; do repeated soap washings. Discard contaminated clothing. Note: see treatment of dermal exposure in the main body of this document for complete information.
If symptoms develop, immediately move individual away from exposure and into fresh air. Flush eyes gently with water for at least 15 minutes while holding eyelids apart; seek immediate medical attention.
