Hazards and Protection.
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.
Protection
Wear appropriate protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary.
Stability
No data.
Incompatibilities
May react vigorously with strong oxidizing agents May react exothermically with reducing agents to release hydrogen gas Violent explosions at low temperatures in ammonia synthesis gas units have been traced to the addition products of unsaturated hydrocarbons and nitrogen dioxide.

Fire.
Fire fighting
Use water in flooding quantities as fog. Use foam, dry chemical, or carbon dioxide. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Keep run-off water out of sewers and water sources.
Fire potential
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.
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.
Combustion products
Fire may produce irritating, corrosive and/or toxic gases.

Health.
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.
   Ingestion
Nausea, vomiting, diarrhea, and abdominal pain may occur following ingestion.
   Inhalation
Coughing, choking, tachypnea, dyspnea, cyanosis, rales, hemoptysis, pulmonary edema, pneumatoceles, lipoid pneumonia, or respiratory arrest may develop following ingestion and aspiration.
   Skin
May cause irritation or burns.
   Eyes
See Skin.

First aid
 
   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.
