[Fire Fighting]

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use agent most appropriate to extinguish fire.
[Fire Potential]

Technical material is not flammable. For the emulsifiable concentrates, use ordinary precautions for volatile solvents.
[Ingestion]

Seek medical attention. If individual is drowsy or unconscious, do not give anything by mouth; place individual on the left side with the head down. Contact a physician, medical facility, or poison control center for advice about whether to induce vomiting. If possible, do not leave individual unattended.
[Inhalation]

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.
[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.
[Storage]

Avoid freezing; store above 40F. Do not store near heat or open flame. Emulsifiable concentrates should not be or stored at temperature near flash-point. Should not be frozen.
[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.
[Inhalation]

Respiratory depression - administration of lethal doses intragastrically to animals resulted in shallow, infrequent, and interrupted respirations within 20 to 25 minutes, with death from respiratory arrest within 3 hours to 2 days.
[Skin]

Hyperemia - single applications of 5% trifluralin to the skin was not irritating to rats. Successive daily applications for 5 days produced mild hyperemia lasting 2 days.
[Ingestion]

RESPIRATORY DEPRESSION - Administration of lethal doses intragastrically to animals resulted in shallow, infrequent, and interrupted respirations within 20 to 25 minutes, with death from respiratory arrest within 3 hours to 2 days.
[Personal Protection]

Wear goggles or face shield when handling concn. Coveralls, long-sleeved shirt, impermeable gloves when handling.
[Respirators]

Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
[Exposure Effects]

CNS depression - administration of lethal doses intragastrically to animals produced flaccidity, adynamia, and tremor. In one mouse study, trifluralin administration was associated with various skeletal anomalies in the offspring.
