| First Aid Measures | Back to Contents | 【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. |
| Handling and Storage | Back to Contents | 【Storage】
Store in cool, dry place. Exposure of water-soluble formulations to air can cause some loss of water solubility. | 【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 | 【Ingestion】
Nausea, vomiting, and diarrhea may be noted following ingestion. | 【Inhalation】
Symptoms: irritation eyes, skin, upper respiratory system; in animals: thyroid injury Target Organs: Eyes, skin, respiratory system, thyroid. | 【Skin】
Cyanosis unresponsive to oxygen therapy may be noted in patients with methemoglobinemia due to absorption of excessive amounts of these agents. | 【Eyes】
See inhalation. |
| Exposure Controls/Personal Protection | Back to Contents | 【Personal Protection】
Wear appropriate personal protective clothing to prevent skin contact. | 【Respirators】
Use NIOSH/MSHA approved respirator appropriate for exposure of concern. | 【Exposure limit(s)】
NIOSH REL: TWA 1 ppm (10 mg/m3) | 【Poison Class】
4 |
| Fire Fighting Measures | Back to Contents | 【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】
Active ingredient and dry formulations are non-flammable; the liquid formulation (hyvar-xl) is a combustible mixture which should be kept away from heat and open flame. |
| Accidental Release Measures | Back to Contents | 【Small spills/leaks】
Evacuate area and ventilate. Wear protective equipment. If required, use an inert absrobent. Sweep up and place in an appropriate container for disposal. Wash contaminated surfaces. |
| Stability and Reactivity | Back to Contents | 【Stability】
Stable up to MP and slowly sublimes @ temperature just below its MP active ingredient is chemically stable under normal storage conditions stable in aqueous bases. Slowly decomposed by concentrated acids. | 【Incompatibilities】
Strong oxidizing agents. | 【Decomposition】
When heated to decomposition it emits very toxic fumes of hydrogen bromide and nitrogen oxides. |
