Poison safety means preventing harmful chemicals, medicines, plants, gases, or contaminated foods from entering the body. It matters at home because many everyday items, such as cleaners, batteries, pesticides, and medications, can be dangerous when used the wrong way. Middle and high school students can help protect family members by recognizing hazards and knowing what to do in an emergency.
Preparedness turns a scary situation into a faster, safer response.
Key Facts
- In a poison emergency in the United States, call Poison Control at 1-800-222-1222 or call 911 if the person is unconscious, not breathing, or having seizures.
- Dose matters: risk increases as the amount of poison per body mass increases, often written as dose = amount of substance / body mass.
- Common routes of poisoning are ingestion, inhalation, skin contact, and eye contact.
- Store medicines, cleaners, pesticides, and batteries in locked or high cabinets away from children and pets.
- Never mix cleaning chemicals because reactions can release toxic gases, such as bleach plus ammonia producing chloramine vapors.
- Label every container clearly and keep chemicals in their original containers to avoid accidental misuse.
Vocabulary
- Poison
- A poison is any substance that can harm the body when it is swallowed, inhaled, injected, or absorbed through skin or eyes.
- Toxicity
- Toxicity is the ability of a substance to cause damage to living tissue.
- Dose
- Dose is the amount of a substance a person is exposed to, often compared with body mass.
- Inhalation
- Inhalation is breathing in a gas, vapor, dust, or mist that may affect the lungs or bloodstream.
- Poison Control

Common Mistakes to Avoid
- Mixing cleaners, especially bleach with ammonia or acids, is dangerous because chemical reactions can produce toxic gases that damage the lungs.
- Storing chemicals in drink bottles is unsafe because someone may mistake the liquid for a beverage and swallow it.
- Waiting to call for help after a suspected poisoning is risky because fast expert advice can prevent worse injury and guide the correct response.
- Trying to make someone vomit without instructions is wrong because some substances can burn the throat again or enter the lungs during vomiting.
Practice Questions

- 2 A family has 3 cleaning sprays, 2 pesticide bottles, 4 medicine bottles, and 1 button battery pack stored under a sink. If all should be moved to a locked cabinet, how many total poison-risk items must be relocated?
- 3 A younger sibling spills an unknown cleaner on their hand and says it burns. Explain the safest first actions and why guessing the chemical or waiting is not a good plan.
