Harmful Substances That Could Be Taken into The Body

Harmful substances are things that can make us sick if we eat, drink, or touch them.

Examples are:

1. Pesticides (used to kill bugs on plants)
2. Cleaning chemicals (like bleach and disinfectants)
3. Expired or spoiled foods
4. Medicines not prescribed to you
5. Alcohol
6. Smoke or fumes from cars or factories

Avoiding these substances is crucial for good health.

How Harmful Substances Enter the Body

Harmful substances may enter through swallowing, breathing, skin contact or the eyes. Household chemicals must never be poured into drink bottles because someone may mistake them for water. Smoke and fumes should not be deliberately inhaled.

If exposure occurs, pupils should move away from danger and alert an adult immediately. They should not force vomiting, mix chemicals or give an unknown remedy. The product container or label can help a responsible adult or health worker decide the correct action.
