CFR 1910.1200. 

Potential Health Effects

Eye Contact: May cause severe eye irritation. May cause slight corneal injury. May cause

Inhalation: No adverse effects are anticipated from single exposure to dust. 

Ingestion: Very low toxicity if swallowed. Harmful effects not anticipated from swallowing small 

amounts. 

Effects of Repeated Exposure: In animals, effects have been reported on the following organs: 

Gastrointestinal tract. 

4. First-aid measures 

Eye Contact: Wash immediately and continuously with flowing water for at least 30 minutes. Remove 

contact lenses after the first 5 minutes and continue washing. Obtain prompt medical consultation, 

preferably from an ophthalmologist. 

Skin Contact: Wash skin with plenty of water. 

Inhalation: Move person to fresh air; if effects occur, consult a physician. 

Ingestion: No emergency medical treatment necessary. 

Notes to Physician: Chemical eye burns may require extended irrigation. Obtain prompt 

consultation, preferably from an ophthalmologist. No specific antidote. Treatment of exposure should 

be directed at the control of symptoms and the clinical condition of the patient. 

5. Fire Fighting Measures 

Extinguishing Media: Water. Dry chemical fire extinguishers. Carbon dioxide fire extinguishers. 

Fire Fighting Procedures: Keep people away. Isolate fire and deny unnecessary entry. Soak 

thoroughly with water to cool and prevent re-ignition. Use water spray to cool fire exposed containers 

and fire affected zone until fire is out and danger of reignition has passed. Fight fire from protected 

location or safe distance. Consider the use of unmanned hose holders or monitor nozzles. 

Immediately withdraw all personnel from the area in case of rising sound from venting safety device or 

discoloration of the container. Hand held dry chemical or carbon dioxide extinguishers may be used 

for small fires. Dust explosion hazard may result from forceful application of fire extinguishing agents. 

Move container from fire area if this is possible without hazard. Contain fire water run-off if possible. 

Fire water run-off, if not contained, may cause environmental damage. Review the “Accidental 

Release Measures” and the “Ecological Information” sections of this (M)SDS. 

Special Protective Equipment for Firefighters: Wear positive-pressure self-contained breathing 

apparatus (SCBA) and protective fire fighting clothing (includes fire fighting helmet, coat, trousers, 

boots, and gloves). If protective equipment is not available or not used, fight fire from a protected 

location or safe distance. 

Unusual Fire and Explosion Hazards: Container may rupture from gas generation in a fire situation. 

Do not permit dust to accumulate. When suspended in air dust can pose an explosion hazard. 

Minimize ignition sources. If dust layers are exposed to elevated temperatures, spontaneous 

combustion may occur. 

Hazardous Combustion Products: During a fire, smoke may contain the original material in addition 

to combustion products of varying composition which may be toxic and/or irritating. 

6. Accidental Release Measures 

Steps to be Taken if Material is Released or Spilled: Contain spilled material if possible. Small 

spills: Sweep up. Collect in suitable and properly labeled containers. Large spills: Contact Dow

AgroSciences for clean-up assistance. See Section 13, Disposal Considerations, for additional 

information. 

Personal Precautions: Evacuate area. Refer to Section 7, Handling, for additional precautionary 

measures. Only trained and properly protected personnel must be involved in clean-up operations. 

Keep upwind of spill. Spilled material may cause a slipping hazard. Ventilate area of leak or spill. 

Use appropriate safety equipment. For additional information, refer to Section 8, Exposure Controls 

and Personal Protection. 

Environmental Precautions: Prevent from entering into soil, ditches, sewers, waterways and/or 

groundwater. See Section 12, Ecological Information. 

7. Handling and Storage 

Handling 

General Handling: Keep out of reach of children. Do not get in eyes. Avoid contact with skin and 

clothing. Wash thoroughly after handling. Avoid breathing vapor. Use with adequate ventilation. 

Keep container closed. Good housekeeping and controlling of dusts are necessary for safe handling 

of product. Keep away from heat, sparks and flame. See Section 8, EXPOSURE CONTROLS AND 

PERSONAL PROTECTION. 

Storage 

Store in a dry place. Store in original container. Do not store near food, foodstuffs, drugs or potable 

water supplies.

Aminopyralid Dow IHG TWA 10 mg/m3 

RECOMMENDATIONS IN THIS SECTION ARE FOR MANUFACTURING, COMMERCIAL 

BLENDING AND PACKAGING WORKERS. APPLICATORS AND HANDLERS SHOULD SEE THE 

PRODUCT LABEL FOR PROPER PERSONAL PROTECTIVE EQUIPMENT AND CLOTHING. 

Personal Protection

Eye/Face Protection: Use chemical goggles. Eye wash fountain should be located in immediate work 

area. 

Skin Protection: Wear clean, body-covering clothing. 

Hand protection: Use gloves chemically resistant to this material when prolonged or 

frequently repeated contact could occur. Examples of preferred glove barrier materials 

include: Neoprene. Nitrile/butadiene rubber (“nitrile” or “NBR”). Polyvinyl chloride (“PVC” or 

“vinyl”). NOTICE: The selection of a specific glove for a particular application and duration of 

use in a workplace should also take into account all relevant workplace factors such as, but 

not limited to: Other chemicals which may be handled, physical requirements (cut/puncture 

protection, dexterity, thermal protection), potential body reactions to glove materials, as well as 

the instructions/specifications provided by the glove supplier. 

Respiratory Protection: Respiratory protection should be worn when there is a potential to exceed 

the exposure limit requirements or guidelines. If there are no applicable exposure limit requirements 

or guidelines, wear respiratory protection when adverse effects, such as respiratory irritation or 

discomfort have been experienced, or where indicated by your risk assessment process. For most 

conditions, no respiratory protection should be needed; however, in dusty atmospheres, use an 

approved particulate respirator. The following should be effective types of air-purifying respirators: 

Organic vapor cartridge with a particulate pre-filter. 

Ingestion: Use good personal hygiene. Do not consume or store food in the work area. Wash hands 

before smoking or eating. 

Engineering Controls

Ventilation: Use local exhaust ventilation, or other engineering controls to maintain airborne levels 

below exposure limit requirements or guidelines. If there are no applicable exposure limit

requirements or guidelines, general ventilation should be sufficient for most operations. Local exhaust 

ventilation may be necessary for some operations.
