| First Aid Measures | Back to Contents | 【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. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. | 【Inhalation】
IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. IMMEDIATELY call a physician and be prepared to transport the victim to a hospital even if no symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used. | 【Skin】
IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment. | 【Eyes】
First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. |
| Handling and Storage | Back to Contents | 【Storage】
Keep in well ventilated area. | 【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 | Back to Contents | 【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】
Eye, nose, and mouth irritation are possible with direct contact. | 【Ingestion】
Nausea, vomiting, and diarrhea have been reported. Necrosis of the gastrointestinal mucosa has been reported. | 【Hazards】
Containers may explode when heated. | 【UN (DOT)】

| Exposure Controls/Personal Protection | Back to Contents | 【Personal Protection】
Wear appropriate chemical protective gloves, boots and goggles. | 【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. | 【Exposure limit(s)】
TLV: ppm; 10 mg/m3 (as TWA) (ACGIH 1994-1995). OSHA PEL: TWA 10 mg/m3 NIOSH REL: TWA 10 mg/m3 NIOSH IDLH: 250 mg/m3 | 【Poison Class】
3 |
| Accidental Release Measures | Back to Contents | 【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. Prevent entry into waterways, sewers, basements or confined areas. 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 | Back to Contents | 【Incompatibilities】
Reacts with organic and inorganic bases to form water-soluble salts and with alcohols to form esters Incompatible with strong oxidizing agents and strong bases. | 【Stability】
Stable @ its melting-point shelf life excellent depending upon mfr and formulation; 2-yr minimum conditions leading to inStability: Temperatures above 158 C may cause sealed metal containers to burst. | 【Decomposition】
Toxic gases and vapors which include: hydrogen chloride and carbon monoxide. When heated to decomposition it emits toxic fumes of hydrogen chloride. | 【Combustion Products】
Toxic hydrogen chloride and phosgene gases may be formed. |
