| [Flash Point] 51 | |
| [Autoignition] 450 | |
| [Fire Fighting] To fight fire, use carbon dioxide, dry chemical. Use water in flooding quantities as fog. Solid streams of water may spread fire. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use foam, dry chemical, or carbon dioxide. | |
| [Upper exp. limit] 5.1 | |
| [Lower exp. limit] .8 | |
| [Fire Potential] Flammable liquid when exposed to heat or flame. Diethyl benzene combustible. Moderate fire risk. | |
| [Ingestion] Pure petroleum distillates - gastric decontamination is not indicated in the majority of accidental ingestions, since systemic toxicity is unlikely from a pure petroleum distillate. Other hydrocarbons - gastric decontamination may be indicated if a large amount of a toxic hydrocarbon has been ingested (e.G., Suicide attempt) and if spontaneous vomiting has not occurred. Decontamination may also be indicated for ingestions of highly toxic hydrocarbons (e.G., Halogenated hydrocarbons, carbon tetrachloride) and for hydrocarbons which contain very toxic additives (e.G., Heavy metals, pesticides). The decision to decontaminate should be based on the toxicity of the agent, the volume ingested, time of ingestion and patient's clinical status. The potential for rapid cns depression, with seizures and/or respiratory depression, must be considered. | |
| [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 wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists. Some chemicals can produce systemic poisoning by absorption through intact skin. Carefully observe patients with dermal exposure for the development of any systemic signs or symptoms and administer symptomatic treatment as necessary. | |
| [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. | |
| [Storage] Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry,well-ventilated area away from incompatible substances. | |
| [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. | |
| [Inhalation] Coughing, choking, tachypnea, dyspnea, cyanosis, rales, hemoptysis, pulmonary edema, pneumatoceles, lipoid pneumonia, or respiratory arrest may develop following ingestion and aspiration. | |
| [Skin] May irritate or burn. May cause toxic effects if absorbed through the skin. | |
| [Eyes] See Skin. | |
| [Ingestion] Nausea, vomiting, diarrhea, and abdominal pain may occur following ingestion. | |
| [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] Wear appropriate protective gloves, clothing and goggles. | |
| [Respirators] Wear positive pressure self-contained breathing apparatus (SCBA). | |
| [Exposure Effects] Mild central nervous system depression or excitation may occur after ingestion or vapor inhalation. CNS effects can occur secondary to hydrocarbon pneumonitis and hypoxia, or from additives and contaminants (aniline, heavy metals, camphor, or pesticides). Some hydrocarbons are simple asphyxiants (e.G., Methane, ethane, propane gasses) which can produce CNS effects secondary to hypoxia. In a prospective study in Toronto, major congenital malformations were noted in 13 of 125 fetuses of mothers exposed to organic solvents during pregnancy. | |

| [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. | |
