FIRST AID ESSENTIALS
A poison is a substance (other than an infectious substance) that is harmful to human health if ingested, inhaled, injected, or absorbed through the skin.
Signs and symptoms
Poisons can cause a wide range of symptoms including:
- Burning pain in the mouth or throat;
- Blurred vision;
- Difficulty breathing;
- Respiratory arrest; and
- Cardiac arrest.
Recognition of poisoning may be obvious from the circumstances of the incident, but this is not always true. A person may complain of physical symptoms without realising these are due to a poison. Alternatively, they may exhibit abnormal behaviour, which may be misinterpreted as alcoholic confusion or psychiatric disturbance.
It is important to seek medical assessment or advice after significant exposure to a poison, even if symptoms are initially mild or absent.
The principles of managing a patient who has been poisoned are:
- Prevention of poisoning of the rescuer.
- Decontamination of the patient.
- Resuscitation and supportive care, using the Basic Life Support Flowchart
If the poison is SWALLOWED:
- Give the person who has swallowed the poison a sip of water to wash out their mouth.
- DO NOT try to make them vomit
If the poison is INHALED:
- Immediately get the person to fresh air, without placing yourself at risk.
- Avoid breathing fumes.
- If it is safe to do so, open doors and windows wide.
If the poison enters the EYE:
- Flood the eye with saline or cold water from a running tap or a cup/jug.
- Continue to flush for 15 minutes, holding the eyelids open.
If the poison contacts the SKIN:
- Remove contaminated clothing, taking care to avoid contact with the poison.
- Flood skin with running cold water.
- Wash gently with soap and water and rinse well.
