Hazards and Protection.
Storage
Do not store near heat or open flame. Store in original container only. Do not contaminate water, seed or feed by storage. Keep away from children.
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
Protective gloves and clothing. Safety goggles or eye protection in combination with breathing protection if powder.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Cover with plastic sheet to prevent spreading. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS.
Stability
Indefinitely stable; not sensitive to light or heat stable to UV radiation.
Incompatibilities
Organic amides/imides react with azo and diazo compounds to generate toxic gases Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents Can react as acids.
Decomposition
On combustion, forms toxic gases (carbon monoxide, nitrogen oxides, HCl).

Exposure effects
CNS excitation progressing to CNS depression is reported in fatally poisoned animals.
   Inhalation
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Effects of contact or inhalation may be delayed.
   Skin
Alachlor may cause allergic skin reactions.
   Eyes
Alachlor may be a mild irritant to the eyes.

First aid
 
   Ingestion
Dilution: immediately dilute with 4 to 8 ounces (120 to 240 ml) of water (not to exceed 15 ml/kg in a child). 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.
   Skin
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
   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.
