  1. Chapter 16 Poisons, Toxins, and Poisonous Plants

  2. Lesson Objectives (1 of 2) • Identify the causes of carbon monoxide poisoning. • Assess and manage carbon monoxide poisoning. • Identify the signs of and know how to manage poison ingestion. • Recognize and treat plant-induced dermatitis.

  3. Overview • Many commonly used products are toxic to some people when used appropriately, and they can be toxic to anyone when used inappropriately. • Chemical poisons are not common in the wilderness. • Should learn the basic principles to treat most poisonings. • Never touch or eat a plant unless you know that it is safe.

  4. Carbon Monoxide Poisoning (1 of 6) • Can be caused by: • Cooking on a stove in a tightly closed tent or snow cave • A camper with a faulty heater or stove • Prolonged use of a car heater with the motor idling

  5. Carbon Monoxide Poisoning (2 of 6) • What to look for: • Flu-like symptoms, generalized aching, or swollen glands • Similar symptoms in others exposed • Sick pets • Difficulty with breathing • Headache

  6. Carbon Monoxide Poisoning (3 of 6) • What to look for: • Ringing in the ears • Chest pain • Muscle weakness • Nausea and vomiting • Dizziness and blurred or double vision • Altered mental status

  7. Carbon Monoxide Poisoning (4 of 6) • What to look for: • Cardiac arrest • In the terminal stages of carbon monoxide poisoning, bright pink skin

  8. Carbon Monoxide Poisoning (5 of 6) • What to do: • Do not go into an enclosed space where someone has collapsed without first trying to determine the cause of the problem. • When it is safe, move the victim into fresh air immediately. • Check breathing.

  9. Carbon Monoxide Poisoning (6 of 6) • What to do: • Give CPR, if necessary. • Give the victim oxygen, if available. • Call for rescue and evacuate as soon as possible.

  10. Toxic Plants and Poisons (1 of 4) • Do not eat plants you cannot identify. • Never eat mushrooms unless you are sure they are safe.

  11. Toxic Plants and Poisons (2 of 4) • What to look for: • Abdominal pain and cramping • Nausea or vomiting • Diarrhea • Burns, odor, and stains around the mouth • Drowsiness or unresponsiveness • Poison containers or evidence of poisonous plants nearby

  12. Toxic Plants and Poisons (3 of 4) • What to do: • Determine critical information: • Age and size of victim • What was swallowed • How much was swallowed • When it was swallowed

  13. Toxic Plants and Poisons (4 of 4) • What to do: • Place the victim on the left side. • Evacuate as soon as possible. • Take a specimen of the plant for identification by an expert.

  15. Plant-Induced Dermatitis (2 of 3) • What to look for: • Itching, redness, swelling, blisters. • Reaction can start 8 to 48 hours after exposure. • Reaction can continue for several days.

  16. Plant-Induced Dermatitis (3 of 3) • What to do: • Wash exposed areas with cold water. • For mild, localized contact, apply calamine lotion or hydrocortisone cream. • For severe, generalized reaction, apply calamine lotion and seek medical care. • Apply hydrocortisone cream, cover with transparent plastic wrap, and bind with a bandage. • Soak affected area in hot water.
