| [Flash Point] 126 | |
| [Fire Fighting] Extinguish with dry chemicals, foam, or carbon dioxide. Water may be ineffective. Cool exposed containers with water. | |
| [Fire Potential] Material itself does not burn or burns with difficulty. | |
| [Ingestion] Seek medical assistance. | |
| [Inhalation] Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols. | |
| [Skin] Remove contaminated clothing and jewelry. Wash the skin, including hair and nails, vigorously; do repeated soap washings. Discard contaminated clothing. Treat dermal irritation or burns with standard topical therapy. Patients developing dermal hypersensitivity reactions may require treatment with systemic or topical corticosteroids or antihistamines. | |
| [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] Store at ambient temperatures with open venting. | |
| [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] Ingestion of large amounts may cause bradypnea, respiratory failure, hyperventilation, or pulmonary edema. | |
| [Skin] Direct contact may cause skin irritation. Chlorodioxin contamination of products may produce chloracne with heavy exposure. | |
| [Eyes] See Skin. | |
| [Ingestion] Nausea, vomiting, and diarrhea have been reported. Necrosis of the gastrointestinal mucosa has been reported. | |
| [Hazards] Containers may explode when heated. | |

| [Personal Protection] See information, this field, in accession number 8400333 (2,4-d esters). | |
| [Respirators] Wear positive pressure self-contained breathing apparatus (SCBA). | |
| [Exposure Effects] Low dose exposures - vertigo, headache, malaise, and paresthesias may occur depending on the specific compound involved. High dose exposures - muscle twitching, spasms, profound weakness, polyneuritis, and unconsciousness may occur depending on the specific compound involved. Idiosyncratic reactions - peripheral neuropathies 2,4-D and 2,4,5-T have caused adverse reproductive effects in experimental animals. Allegations of human birth defects due to these compounds have not been confirmed. | |
