First Aid Measures

Ingestion
DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician.
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.

Handling and Storage

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.

Hazards Identification

Inhalation
Ingestion of large amounts may cause bradypnea, respiratory failure, hyperventilation, or pulmonary edema.
Skin
Direct contact may cause skin irritation.
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.

Exposure Controls/Personal Protection

Personal Protection
Wear appropriate clothing to prevent any reasonable probability of skin contact. Wear eye protection to prevent any possibility of eye contact.
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.

Fire Fighting Measures

Fire Fighting
U.S. Coast guard recommendations-extinguish with dry chemicals, foam, or carbon dioxide. Water may be ineffective. Use water to cool exposed containers. (Cghcd* 78/uscg) DOT recommendations (same as for 2,4-d acid)-small fires: dry chemical, carbon dioxide, waterspray, or foam. Large fires: water spray, fog, or foam. Fight fire from maximum distance. If you can do so without risk, move container from fire area. bureau of explosives recommendations-use extinguishing agent suitable for type of surrounding fire.).
Fire Potential
Combustible material: may burn but does not ignite readily.

Accidental Release Measures

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 and Reactivity

Stability
No data.
Incompatibilities
Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products.
Combustion Products
Fire may produce irritating, corrosive and/or toxic gases.
