See Section 9 for Flammability Properties 



Slight fire hazard. Dust/air mixtures may ignite or explode. 



regular dry chemical, carbon dioxide, water, regular foam 

Large fires: Use regular foam or flood with fine water spray. 

Move container from fire area if it can be done without risk. Do not scatter spilled material with high-pressure water streams. Dike for later disposal. Use extinguishing agents appropriate for surrounding fire. Avoid inhalation of material or combustion by-products. Stay upwind and keep out of low areas. 









Stop leak if possible without personal risk. Small spills: Absorb with sand or other non-combustible material. Collect spilled material in appropriate container for disposal. Keep unnecessary people away, isolate hazard area and deny entry. Notify Local Emergency Planning Committee and State Emergency Response Commission for release greater than or equal to RQ (U.S. SARA Section 304). If release occurs in the U.S. and is reportable under CERCLA Section 103, notify the National Response Center at (800)424-8802 (USA) or (202)426-2675 (USA). 









Store and handle in accordance with all current regulations and standards. May be subject to EPA pesticide registration. Keep separated from incompatible substances. 

Component Exposure Limits 

Biological limit value 



Provide local exhaust ventilation system. Ventilation equipment should be explosion-resistant if explosive concentrations of material are present. Ensure compliance with applicable exposure limits. 



Eyes/Face Wear splash resistant safety goggles with a faceshield. Provide an emergency eye wash fountain and quick drench shower in the immediate work area. 



Wear appropriate chemical resistant clothing. 



Wear appropriate chemical resistant gloves. 



Under conditions of frequent use or heavy exposure, respiratory protection may be needed. Respiratory protection is ranked in order from minimum to maximum. Consider warning properties before use. Any supplied-air respirator with a full facepiece that is operated in a pressure-demand or other positive-pressure mode. Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode. For Unknown Concentrations or Immediately Dangerous to Life or Health - Any supplied-air respirator with a full facepiece that is operated in a pressure-demand or other positive-pressure mode in combination with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive-pressure mode. Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode.

Component Carcinogenicity

None of this product's components are listed by ACGIH, IARC, NTP, DFG or OSHA

Studies revealed a significant increase in soft-tissue sarcomas, malignant lymphomas and bronchial carcinomas in workers exposed to chlorophenoxy herbicides. 

respiratory disorders, skin disorders and allergies, 



DICAMBA DIMETHYLAMINE SALT: May cause irritation of the mucous membranes 2,4-D AND DERIVATIVES: Exposure to 2,4-D and its derivatives may cause irritation with sore throat and burning sensations in the nasopharynx and chest, coughing, lacrimation, rhinitis, dullness, dizziness, and ataxia Other effects of fatigue, nausea, vomiting, diarrhea, stomach pains, malaise, headache, fever, tachycardia, urinary incontinence, constipation, leukopenia, myalgia, and transient unconsciousness may occur A delayed peripheral neuropathy may develop characterized by paresthesias, severe pain, symmetrical motor and sensory deficits, weakness, myotonia, fasciculations, and in some cases paralysis of the extremities The disability may be prolonged and recovery incomplete.



DICAMBA DIMETHYLAMINE SALT: Effects on the liver, kidney, and lung were observed in laboratory animals exposed to dicamba salts 2,4-D AND DERIVATIVES: In addition to the effects listed in acute exposure, occupational exposure to 2,4-D and its derivatives has produced a sweet taste in the mouth, hyperacusia, lowered sensitivity to taste and smell, increased salivation, vertigo, somnolence, anorexia, heaviness of the legs Other effects have included hypotension, bradycardia and other cardiovascular system changes, pain in the region of the liver and stomach, and changes in the digestive function, liver function and metabolic processes A case report described a child with multiple congenital anomalies and severe mental retardation of uncertain cause born to parents heavily exposed to 2,4-D while spraying trees An increased prevalence of slowed nerve conduction velocity with no associated symptoms was reported in a study of chemical workers employed in the production of 2,4-D and 2,4,5-T Epidemiological studies revealed a significant increase in soft-tissue sarcomas, malignant lymphomas, and bronchial carcinomas in workers exposed to chlorophenoxy herbicides including 2,4-D.



(2,4-DICHLOROPHENOXY)ACETIC ACID DIMETHYLAMINE See information on 2,4-D and derivatives.



DICAMBA DIMETHYLAMINE SALT: May cause irritation Dicamba has produced moderate sensitization in guinea pigs 2,4-D AND DERIVATIVES: May cause irritation If sufficient amounts are absorbed through the skin, effects, including peripheral neuropathy, as described in acute inhalation may occur.

DICAMBA DIMETHYLAMINE SALT See information on corrosive substances.



DICAMBA DIMETHYLAMINE SALT: In laboratory animals, acute doses of dicamba produced myotonic muscular spasms, exhaustion, urinary incontinence, dyspnea, cyanosis, and death Minor lung hemorrhages were found in some animals Most survivors recovered in 2 to 3 days and showed no macroscopic pathology 2,4-D AND DERIVATIVES: Ingestion of 2,4-D and its derivatives may cause irritation of the mouth, throat, and gastrointestinal tract, nausea, vomiting, chest and abdominal pain, and diarrhea Ingestion of very large doses may produce metabolic acidosis, fever or subnormal temperatures, hyperventilation, hypotension, vasodilation, flushing of the skin, sweating, cardiac arrhythmias, tachycardia, lethargy, weakness, intercostal paralysis, renal and hepatic dysfunction, myotonia, coma, and convulsions Damage to skeletal muscle may be manifest by muscle twitching and aching with elevated serum enzymes and myoglobin in the blood and urine Impaired memory and changes in color vision were reported in one case of poisoning Death may be due to circulatory collapse.



DICAMBA DIMETHYLAMINE SALT: Slight liver necrosis and cytoplasmic vacuolization were recorded at 800 ppm in a 90-day feeding study with rats Some effects on the kidney and lung were observed in laboratory animals fed dicamba salts 2,4-D AND DERIVATIVES: No data available.
