Hydrocarbon Poisoning: Symptoms, Risks, and Emergency Care

Hydrocarbon poisoning occurs when substances such as fuels, solvents, or petroleum-based products are inhaled or swallowed. These products are commonly found in items like gasoline, kerosene, lighter fluid, paint thinners, and certain cleaning or industrial products.

In Canada, hydrocarbon exposure is a serious safety concern—especially for young children, who are more likely to ingest these substances accidentally, and adolescents, who may be exposed through intentional inhalation. This article is intended for public education and prevention awareness and does not replace medical advice or emergency care.

Why Hydrocarbon Poisoning Is Dangerous

Hydrocarbons are easily inhaled into the lungs or absorbed into the body. The health effects depend on:

The type of hydrocarbon
Whether it was swallowed or inhaled
The amount and concentration
The age and health of the person exposed

A major risk after ingestion—particularly in young children—is aspiration pneumonitis, which occurs when the substance enters the lungs.

Signs and Symptoms of Hydrocarbon Poisoning

After Ingestion

Even a small amount can cause immediate symptoms, including:

Coughing or choking
Gagging or vomiting
Burning sensation in the stomach (more common in older children and adults)

Young children may also experience:

Bluish colouring of the lips or skin (cyanosis)
Breath-holding episodes
Persistent coughing

Aspiration into the lungs can lead to hypoxia (low oxygen levels) and respiratory distress, sometimes developing over several hours.

After Inhalation

Inhalation exposure, more often seen in adolescents, can be extremely dangerous and unpredictable.

Possible effects include:

Dizziness or confusion
Heart rhythm disturbances
Sudden collapse due to serious arrhythmias
Seizures, lethargy, or coma with certain hydrocarbon types

Some heart rhythm disturbances can occur without warning, particularly if the person becomes agitated.

How Hydrocarbon Poisoning Is Diagnosed

Diagnosis is based on a combination of symptoms, history, and testing.

Healthcare providers may:

Perform pulse oximetry to measure oxygen levels
Order a chest X-ray, usually several hours after exposure
Look for clues such as chemical odour on breath or clothing
Assess for paint or fuel residue on the hands or around the mouth

Aspiration pneumonitis is diagnosed using symptoms along with imaging and oxygen measurements. Additional tests may be needed if breathing becomes compromised.

Management and Medical Care

Hydrocarbon poisoning is treated with supportive care.

Key steps include:

Removing contaminated clothing
Thoroughly washing exposed skin
Monitoring breathing ОБand oxygen levels
Avoiding induced vomiting or stomach emptying, which can increase lung injury

Individuals who remain symptom-free after a period of observation may be discharged. Those with respiratory symptoms or other complications require hospitalization and close monitoring.

Prevention Tips for Families and Workplaces

Store fuels and solvents in locked, clearly labelled containers
Keep hazardous products out of children’s reach
Never store chemicals in drink bottles or food containers
Ensure good ventilation when using hydrocarbon-containing products
Educate teens about the serious risks of inhalant exposure

Prompt recognition and safe storage play a critical role in preventing serious injury.
