If any fuel is swallowed, call a physician or
poison control center immediately. Do not delay
calling a physician merely because no adverse
effects are noticed at first; the toxic effects of a
gasoline-methanol blend, including blindness,
may not become apparent for many hours. If
gasoline is swallowed, do not induce vomiting.
If a gasoline-methanol blend is swallowed,
induce vomiting under the direction of a
physician or poison control center.
Gasoline and gasoline-methanol blends may
contain small amounts of carcinogens, such as
benzene. Long-term exposure to unleaded
gasoline vapors has caused cancer in laboratory
animals. Further, excessive inhalation of fuel
vapors can cause headache, dizziness, nausea,
loss of coordination, and other symptoms which
could interfere with your ability to safely
operate your vehicle. To the extent possible,
avoid breathing vapors while refueling. If fuel
vapors are inhaled in excessive quantities, move
the victim to fresh air and seek medical
attention.
Fuels can also be harmful if absorbed through
the skin. When refueling, be careful not to
splash fuel on yourself or your clothing. If fuel
is splashed on the skin, promptly remove
contaminated clothing and wash the skin
thoroughly with soap and water.
Fuels can cause severe eye irritation and possibly
eye damage. If fuel is splashed in the eyes,
remove contact lenses (if worn), flush with large
amounts of water for 15 minutes, and seek
medical attention.
