Use fuel oil only in well-ventilated areas. Large spills should be cleaned by a professional. All spills require significant cleaning and venting.
Tightly seal and properly label storage containers and be sure to vent kerosene heaters outdoors. This will reduce your exposure to carbon monoxide, a deadly gas that can be formed as kerosene burns.
Fuel oil is a general term for a number of burnable liquids made from crude oil. Most common is fuel oil No.1 (also called kerosene), range oil, and jet fuel (JP5). Fuel oils 1-D and 2-D are diesel fuels. Fuel oil No. 2 is home heating oil, and fuel oil No. 4 is a diesel fuel for boats. All fuel oil mixtures have similar chemical and physical properties.
Fuel oils are used to run many types of engines, lamps and heaters. Sometimes small amounts of fuel oil are stored in portable containers for use in space heaters, to clean metal parts, or used in camp stoves or lanterns.
Most fuel oil entering the environment comes from spills or leaking storage tanks. When spilled on soil, some components of fuel oil attach to soil. Furthermore, fuel spilled on water or soil evaporates into the air. Fuel oil can also contaminate soil sediments and private drinking water supplies.
People can breathe fuel oil vapors when filling tanks or after a spill. Other situations include using kerosene heaters, or using kerosene to clean machinery or paint brushes. If water supplies are contaminated, people can inhale the vapors as they bathe, do laundry or use the water for other household purposes. Low-level exposure can occur when contaminated water is used for drinking and for preparing food. Fuel oil spills in basements or attached garages can seriously contaminate the air inside of homes.
Some fuel oil can pass through the skin when people use it as a solvent, spill it on their skin, or use contaminated water. Since some of the chemicals in fuel oil attach to soil particles, children can be exposed as they play in contaminated soil.
No standards exist for the amount of fuel oil vapors allowed in homes or workplaces. Most people can smell fuel oil at levels as low as 0.1 parts per million (ppm) in air.
Although there are no drinking water standards for fuel oil, there are standards for some of its ingredients. "Aromatic" compounds, such as benzene, toluene, and xylene, make up about 35% of fuel oil. The standard for benzene is 5 parts per billion (ppb), toluene is 1 part per million (ppm), and xylene is 10 ppm. We suggest you stop drinking or cooking with water containing these chemicals at levels higher than the standard, or if you smell a kerosene odor or see a oily sheen. If levels are very high, you should avoid washing, bathing, or using the water for other purposes as well.
Everyone's Reaction is Different
A person's reaction to chemicals depends on several things, including individual health, heredity, previous exposure to chemicals including medicines, and personal habits such as smoking or drinking. It’s also important to consider the length of exposure to the chemical, the amount of chemical exposure, and whether the chemical was inhaled, touched, or eaten.
Most people can withstand short exposures to fuel oil vapors without any problems. However, breathing fuel oil vapors over time can affect a person's ability to smell and taste. High levels can cause headaches, nausea, lightheadedness, poor coordination, increased blood pressure and difficulty concentrating. Skin contact with fuel oil can cause irritation that results in itchiness, redness, pain, blisters, and peeling.
Swallowing fuel oil can cause vomiting, diarrhea, swelling of the stomach, cramps, coughing, drowsiness, restlessness, irritability and breathing difficulties. Drinking more than an ounce can result in coma or death. Most accidental poisonings involve children, and many of these children drink kerosene that was being kept in old soft drink bottles.
Exposure to fuel oil is not known to cause cancer in humans. However, long-term exposure to benzene, the most toxic component of fuel oil, is known to cause leukemia. Prolonged or high level exposures to fuel oil can cause kidney and liver damage, nervous system damage, increased blood pressure and reduced blood clotting.
Fuel oil leaves the body within 2-3 days. Although benzene, toluene, and xylene can be measured in blood, there is no good method to determine the level of your exposure. Through tests of the nervous system, kidneys, liver and blood your doctor can evaluate the health effects of fuel oil exposure.
Seek medical advice if you have any symptoms that you think may be related to chemical exposure.
