Hazards and Protection.
Storage
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.
Handling
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.
Protection
Wear protective clothing when working with undiluted preparation.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
(Non-Specific -- Carbamate Pesticide, Solid, n.o.s.) Keep unnecessary people away; isolate hazard areas and deny entry. Stay upwind and keep out of low areas. Do not touch spilled material or breathe the dusts, vapors, or fumes from burning materials. Use water spray to reduce vapors. Do not handle broken packages without protective equipment. Wash away any material that may have contacted the body with soap and water. Take up small spills with sand or other noncombustible absorbent material and place in containers for later disposal. Small dry spills: with clean shovel place material into clean, dry container and cover; move containers from spill area. Dike far ahead of large spills for later disposal.
Stability
No change at 50 C for 140 hr, half life @ pH 7, 310 hr and @ pH 9, 5.7 Hr. Hydrolyzed in alkalies.
Incompatibilities
Incompatible with strong acids and bases, and especially

Fire.

Fire fighting
(Non-Specific -- Carbamate Pesticide, Solid, n.o.s.) Stay upwind; keep out of low areas. 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. Wear positive pressure breathing apparatus and special protective clothing.(Non-Specific -- Carbamates) Extinguish fire using agent suitable for the 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. (Non-Specific -- Carbamate Pesticide, Solid, n.o.s.) This material may burn, but does not ignite readily. For small fires, use dry chemical, carbon dioxide, water spray, or foam. For large fires, use water spray, fog, or foam.
Fire potential
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.
Hazards
Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion and poison hazard indoors, outdoors or in sewers.
Combustion products
Fire will produce irritating, corrosive and/or toxic gases.

Exposure effects
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. Dystonic reaction may occur following parenteral injection. 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.
   Ingestion
Nausea, vomiting, diarrhea, and abdominal cramping may be noted.
   Inhalation
Dyspnea, rales, and pulmonary edema may occur.
   Skin
See inhalation.
   Eyes
See inhalation.

First aid
 
   Ingestion
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.
   Inhalation
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 and isolate contaminated clothing and shoes.
   Skin
Remove contaminated clothing and jewelry. Wash the skin, including hair and nails, vigorously; do repeated soap washings. Discard contaminated clothing.
   Eyes
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.
