Lighter fluid is a flammable liquid used to ignite charcoal, grills, and other combustible materials. Ingesting this substance, even in small amounts, poses significant health risks, leading to severe poisoning and potentially life-threatening complications. Immediate medical attention is crucial if exposure occurs.
Understanding Lighter Fluid’s Composition
Lighter fluid primarily consists of hydrocarbons, organic compounds made of hydrogen and carbon atoms. Common components include petroleum distillates like naphtha, kerosene, or mineral spirits. Wick-based lighters often use naphtha, while gas-type lighters contain butane or isobutane. Charcoal lighter fluids can be petroleum-based or alcohol-based, such as methanol or ethanol. These substances are highly volatile and vaporize quickly, making them effective fuels but also dangerous if consumed.
Immediate Effects of Ingestion
Ingesting lighter fluid causes rapid symptoms. A burning sensation develops in the mouth, throat, and esophagus due to chemical irritation, leading to severe pain and difficulty swallowing. Nausea, vomiting, and abdominal pain are common, sometimes accompanied by blood in vomit or stool. A chemical odor on the breath may also be present.
Pulmonary aspiration is an immediate risk, occurring when fluid or stomach contents are inhaled into the lungs during ingestion or vomiting. This triggers coughing, choking, and difficulty breathing. Aspiration can lead to chemical pneumonitis, a lung condition where chemicals irritate and damage lung tissues.
Potential Internal Damage
Beyond immediate irritation, lighter fluid can cause severe internal damage, especially if aspirated or absorbed into the bloodstream. Aspiration leads to chemical pneumonitis, characterized by inflammation and damage to lung tissue. This can progress to acute respiratory distress syndrome (ARDS), a life-threatening condition where fluid accumulates in the lungs, hindering oxygen exchange. Nonfatal pneumonitis may resolve over one week, though severe cases can take longer.
Systemic absorption of hydrocarbons affects the central nervous system (CNS), causing dizziness, confusion, lethargy, and sleepiness. In severe cases, individuals may experience seizures or a coma. Hydrocarbons can also sensitize the heart muscle to catecholamines, increasing the risk of abnormal heart rhythms, including fatal ventricular arrhythmias. Less commonly, severe poisoning may impact the kidneys and liver, with some halogenated hydrocarbons causing damage days after ingestion.
Crucial Steps After Exposure
Immediate action is crucial if someone has ingested lighter fluid. Call for emergency medical help, contacting 911 or the Poison Control Center (1-800-222-1222). Provide information about the substance, quantity, and the person’s condition. Do not induce vomiting, as this significantly increases aspiration risk and worsens lung damage.
While waiting for help, move the person to fresh air if fumes were inhaled. Do not give anything by mouth if swallowing is difficult, or if there is vomiting or decreased alertness. If fluid contacted skin or eyes, flush the area with plenty of water for at least 15 minutes. Medical evaluation and monitoring in a hospital are necessary to manage symptoms and address any developing internal damage.
