Last updated Feb. 26, 2018

Approved by: Maulik P. Purohit MD MPH

Diesel Oil Poisoning is the accidental or intentional intake of the compound. The intake may be through swallowing diesel oil or inhaling its fumes.


What is Diesel Oil Poisoning?

  • Diesel oil or diesel is a byproduct of petroleum distillation. It can be also derived from non-petroleum products including biogas, natural gas, fatty-acid methyl ester (biodiesel), dimethyl ether, and hydrogenated oils and fats
  • Diesel is colorless liquid with a distinctive odor that is used as a commercial and vehicular fuel including as a fuel for heavy equipment, railroad, and aircraft
  • Diesel Oil Poisoning is the accidental or intentional intake of the compound. The intake may be through swallowing diesel oil or inhaling its fumes
  • The condition is diagnosed based upon the clinical history, combination of signs and symptoms, and additional tests (that may include, in some cases, radiological studies and laboratory tests)

Diesel Oil Poisoning may be also referred to as the following:

  • Diesel Oil Toxicity
  • Diesel Poisoning
  • Diesel Toxicity

What are the Causes of Diesel Oil Poisoning?

  • Diesel Oil Poisoning is caused by the ingestion or inhalation of diesel oil. The chemical may also get into the eye, resulting in eye-related symptoms
  • This intake could be accidental, or in some cases intentional, to bring self-harm
  • Diesel oil is a toxic substance that is also readily combustible. It generally has other added compounds

Note: The compound can interact with other prescribed or non-prescribed medications in the body. Such interactions may enhance the therapeutic effects of other medications being taken, resulting in undesired side effects.

What are the Signs and Symptoms of Diesel Oil Poisoning?

The signs and symptoms of Diesel Oil Poisoning can vary from one individual to another. It may be mild in some and severe in others. Several systems of the body, such as the digestive system, respiratory system, vascular system, nervous system, skin and ENT may be affected.

The signs and symptoms of Diesel Oil Poisoning may include:

  • Burning and associated pain in the mouth, throat, and food-pipe; this may affect the nose, ears, and eyes
  • Respiratory difficulties, if the chemical is inhaled; asphyxiation may occur
  • Throat inflammation may cause difficulty in swallowing, breathing
  • Skin burns
  • Vision abnormalities including loss of vision
  • Headache and lethargy
  • Nausea, vomiting (blood in vomit may be seen)
  • Bloody stools
  • Stomach and abdominal pain that may be cramping
  • Sudden reduction in blood pressure (hypotension)
  • Feeling dizzy or drowsy
  • Low level of alertness or response; sleepiness
  • Individuals act ‘drunk’ or agitated
  • Unable to walk properly; lack of coordinated movements
  • Seizures
  • Collapse and coma

Pulmonary complications may include the following (mostly on inhalation of the vapor fumes):

  • Pleural effusion
  • Respiratory failure
  • Chemical pneumonitis
  • Hemorrhagic lung edema (bleeding in the lungs)
  • Lung collapse (pneumothorax)
  • Development of secondary infections including pneumonia
  • Empyema, or the accumulation of pus in the pleural cavity
  • Brain damage from reduced oxygen supply to the brain

How is First Aid administered for Diesel Oil Poisoning?

First Aid tips for Diesel Oil Poisoning:

  • Call 911 or your local emergency help number immediately, for emergency assistance
  • Call the Poison Control Center at 1-800-222-1222 (or your local poison control center) for further instructions
  • Provide them with information such as the compound taken, quantity and time of ingestion, age, weight and general health status of affected individual
  • Carefully remove the individual from the exposure area; move them to region of fresh air immediately
  • Confirm that the airways are protected; also, ensure breathing and the presence of pulse
  • If exposure of the eye has occurred, then wash thoroughly with copious amounts of water. Any paint on skin may be washed away
  • Unless instructed by a healthcare professional, DO NOT induce vomiting in the affected individual
  • Following an ingestion of the substance, immediately give water or milk to drink
  • In case of symptoms that indicate difficulty in swallowing including vomiting or decreased alertness, do not give anything by way of mouth
  • Take individual to emergency room (ER) for further treatment
  • Always try to take the compound bottle/container to the ER

The emergency medical health professional might perform the following steps towards treating the condition:

  • Monitor vital signs
  • Medically manage symptoms and provide breathing support, if necessary
  • Gastric lavage for elimination of the substance from the stomach (irrigation using special solutions)
  • Wash eyes or skin repeatedly and thoroughly (irrigation), to eliminate any remaining compound
  • Surgical treatment for skin burns including removal of burnt skin
  • Administer fluids by an intravenous drip line

Who should administer First Aid for Diesel Oil Poisoning?

First aid for Diesel Oil Poisoning is administered by healthcare professionals.

  • The individual who is affected, or someone near, should call 911 for emergency assistance (or the local emergency number)
  • They should also call the poison control center at 1-800-222-1222 (or the local poison control center) and follow instructions

What is the Prognosis of Diesel Oil Poisoning?

  • The prognosis of Diesel Oil Poisoning is dependent on the amount of substance consumed, time between consumption and treatment, severity of the symptoms, as well as general health status of the patient
  • If the individual can recover from the symptoms, with appropriate medication and early support, the outcome is generally good. This is mostly the case with mild poisoning
  • Since, diesel oil is a poisonous substance, the severity of damage to the body, and consequently the prognosis, is dependent on the amount of chemical ingested and promptness with which treatment is provided
  • In some case, damage to the mouth, throat, or gastrointestinal tract may be severe. This can lead to severe pain, bleeding, and infection, and potentially worsen the outcome. The internal injuries may continue to worsen and deaths have been reported following a few weeks to months
  • In case of complications, such as aspiration of swallowed oil into the lungs or eye exposure leading to blindness (if the cornea is affected), the outcome may be adversely affected

In general, toxicities are common situations in the emergency departments. A majority of the cases are often not fatal, when appropriate treatment is given.

How can Diesel Oil Poisoning be Prevented?

Diesel Oil Poisoning can be prevented by:

  • Avoiding siphoning diesel oil with your mouth from an automobile tank using a tube
  • Always following instructions for usage of any household products
  • Keeping any poisonous/hazardous chemicals and other materials out of children’s reach
  • Keep all poisons correctly labeled and in suitable storage locations
  • Using appropriate protective wear when working with such chemicals (such as face masks and hand gloves)
  • Being aware of basic first aid steps in case of an emergency (such as inadvertent poisoning)

What are certain Crucial Steps to be followed?

  • Call 911 (or your local emergency number) for emergency assistance, if symptoms are life-threatening
  • Call Poison Control Center at 1-800-222-1222 (or the local poison control center) and follow the recommend steps
  • It would be helpful if the following information is readily available:
    • Type, amount and time of intake of the substance
    • Age and weight of the individual
    • And, the overall health status of the individual
