Science Test

🔥 Flame

Hazard: Flammable (catches fire easily)
Think: Flame = FIRE
👉 Examples: alcohol, gasoline

🧠 Memory trick: If you see fire, it can catch fire.

🔥⭕ Flame over Circle

Hazard: Oxidizer (makes fires burn stronger)
Think: Fire + oxygen = bigger fire
👉 It doesn’t burn itself, but helps other things burn

🧠 Memory trick: Circle = oxygen feeding the flame

🧯 Gas Cylinder

Hazard: Gases under pressure
Think: Compressed gas tank
👉 Can explode if heated or damaged

🧠 Memory trick: Cylinder = tank = pressure

🧪 Corrosion

Hazard: Corrosive

• Causes serious eye damage

• Burns skin

• Eats through metal

🧠 Memory trick: Liquid eating a hand = eats stuff

💥 Exploding Bomb

Hazard: Explosive
👉 Can explode if dropped, heated, or shocked

🧠 Memory trick: Bomb = BOOM

☠ Skull and Crossbones

Hazard: Acute toxicity (fatal or toxic)
👉 Can kill you quickly if swallowed, inhaled, or touched

🧠 Memory trick: Skull = death

🌳🐟 Environment

Hazard: Aquatic toxicity
👉 Harmful to fish, plants, and water life

🧠 Memory trick: Dead tree + fish = bad for nature

🫁 Health Hazard

Hazards include:

• Carcinogenicity (can cause cancer)

• Respiratory sensitization (breathing problems)

• Aspiration hazard (can enter lungs)

🧠 Memory trick: Person with star in chest = inside your body damage

❗ Exclamation Mark

Hazards include:

• Skin or eye irritation

• Skin sensitization

• Harmful (not deadly, but dangerous)

🧠 Memory trick: ❗ = WARNING

🦠 Biohazardous (sometimes listed separately)

Hazard: Biohazardous infectious materials
👉 Bacteria, viruses, blood

🧠 Memory trick: Bio = living germs

✏ TEST ANSWER TEMPLATE (USE THIS)

🧠 ONE-MINUTE MEMORY BOOST (DO THIS TONIGHT)

Say this out loud 3 times:

• Fire burns

• Circle feeds fire

• Cylinder = pressure

• Corrosion eats

• Bomb explodes

• Skull kills

• Tree & fish = environment

• Chest symbol = long-term health

• Exclamation = irritation
