Note: Excessive amounts of any burnable dusts can produce explosive mixtures if allowed to disperse in the air in confined
areas where ignition sources occur. Prevent excessive dust dispersal in areas of use, storage, or production.
Protective equipment and precautions for firefighters
As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and
standard protective gear.
Personal precautions, protective equipment, and emergency procedures
Personal Precautions Use reasonable personal protective equipment as required to prevent contact with eyes or
skin and to avoid breathing dust. Remove ignition sources prior to clean-up.
Environmental precautions Prevent entry into waterways, sewers, basements or confined areas. Do not flush into
surface water or sanitary sewer system. See Section 12 for additional ecological
information.
Methods for containment Prevent further leakage or spillage, if safe to do so.
Methods for clean-up Use reasonable personal protective equipment as required. Cover powder spill with plastic
sheet or tarp to minimize spreading and keep powder dry. Take up mechanically, placing
in appropriate containers for disposal. Avoid creating dust. Clean contaminated surface
thoroughly. Soak up excess with inert absorbent material.
Safe Handling Use only outdoors or in well-ventilated area. Get special instructions before use. Do not handle until
all safety precautions have been read and understood. Avoid breathing dust. Use personal
protective equipment as required. Wash hands thoroughly after handling.
Storage Conditions Keep containers tightly closed in a cool, well- ventilated place. Store locked up. Keep out of the
reach of children. Keep away from food, drink and animal feed.
Incompatible materials Avoid strong acids or alkali, or other reactive substances.

2, 4-Dichlorophenoxyacetic acid 2-ethylhexyl ester (2,4-D ester) is an analogue of 2,4-D. Toxicological and exposure data is typically
referenced to the related parent compound, 2,4-D, as is done here.
Engineering controls: Use with adequate ventilation to prevent dust buildup in air.
