| [Fire Fighting] Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. | |
| [Fire Fighting] Use of water spray when fighting fire may be inefficient. Small Fires: Dry chemical, carbon dioxide, water spray or alcohol-resistant foam. Large Fires: Water spray, fog or alcohol-resistant foam. Use water spray or fog; do not use straight streams. | |
| [Fire Potential] HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. | |
| [Fire Potential] This material is nonflammable | |
| [Ingestion] DO NOT INDUCE VOMITING. Volatile chemicals have a high risk of being aspirated into the victim's lungs during vomiting which increases the medical problems. 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. IMMEDIATELY transport the victim to a hospital. | |
| [Ingestion] Seek medical assistance. | |
| [Inhalation] Vapors may cause dizziness or suffocation. May cause irritation or burns. | |
| [Inhalation] IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used. | |
| [Inhalation] Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. | |
| [Skin] May cause irritation or burns. | |
| [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. | |
| [Skin] Remove and isolate contaminated clothing and shoes. Wash skin with soap and water. Flush with running water for at least 20 minutes | |
| [Eyes] See Skin. | |
| [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. | |
| [Eyes] Flush with running water for at least 20 minutes. | |
| [Storage] Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage. | |
| [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. | |
| [Ingestion] See inhalation. | |
| [Inhalation] Symptoms of exposure to this compound include irritation of the skin, eyes, mucous membranes and upper respiratory tract. | |
| [Skin] See inhalation. | |
| [Eyes] See inhalation | |
| [Hazards] Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. | |

| [Personal Protection] Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Whre chemical resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots. | |
| [Personal Protection] Wear appropriate protective gloves, clothing and goggles. | |
| [Respirators] Wear positive pressure self-contained breathing apparatus (SCBA). | |
| [Respirators] When working with this chemical, wear a NIOSH-approved full face chemical cartridge respirator equipped with the appropriate organic vapor cartridges. If that is not available, a half face respirator similarly equipped plus airtight goggles can be substituted. However, please note that half face respirators provide a substantially lower level of protection than do full face respirators. | |

| [Small spills/leaks] If you should spill this chemical, use absorbent paper to pick up all liquid spill material. Seal the absorbent paper, as well as any of your clothing which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Wash any surfaces you may have contaminated with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned. | |
| [Small spills/leaks] Make no contact with the spilled material. ELIMINATE all ignition sources and ground all equipment. Stop leak if you can do it without risk. A vapor suppressing foam may be used to reduce vapors. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Use clean non-sparking tools to collect absorbed material. | |
| [Incompatibilities] Incompatible with strong oxidizing agents and bases Flammable and/or toxic gases are generated by the combination with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents Can react with air to give first peroxo acids, and ultimately carboxylic acids. | |
