4 | health hazard |
1 | harmful for our bodies or the ozone layer |
9 | harmful or fatal – acute toxicity |
6 | harmful to the environment |
1 | explosion or other reactivity hazards |
8 | compressed gas |

Answer:

To solve this WHMIS (Workplace Hazardous Materials Information System) symbol - matching problem, we analyze each symbol, its name, and the safety implications:

Symbol 1 (Explosion/Reactivity Hazard)

• Name/Explanation: Explosion or other reactivity hazards.
• In Your Own Words: This symbol means the material can explode or have violent chemical reactions. To stay safe, we should avoid exposing it to heat, shock, or incompatible substances, and handle it with extreme care.

Symbol 2 (Flammable Material)

• Name/Explanation: Flammable material.
• In Your Own Words: The material can easily catch fire. We should keep it away from open flames, sparks, and hot surfaces, and use proper fire - safety equipment if handling it.

Symbol 3 (Oxidizing Material)

• Name/Explanation: Oxidizing material.
• In Your Own Words: This material can make other substances burn more easily or intensely. We should store it separately from flammable materials and avoid mixing it with combustibles.

Symbol 4 (Harmful for Body/Ozone)

• Name/Explanation: Harmful for our bodies or the ozone layer.
• In Your Own Words: The material is damaging to our health (like causing irritation or illness) or harms the ozone layer. We should use proper personal protective equipment (PPE) like gloves and masks, and follow disposal guidelines to protect the environment.

Symbol 5 (Corrosion)

• Name/Explanation: Corrosion.
• In Your Own Words: The material can damage or destroy other materials (like metals) or harm living tissue (like skin). We should use corrosion - resistant containers and wear protective gear to prevent contact.

Symbol 6 (Harmful to Environment)

• Name/Explanation: Harmful to the Environment.
• In Your Own Words: The material can damage ecosystems, plants, or animals. We should dispose of it properly, following environmental regulations, and avoid releasing it into the environment.

Symbol 7 (Health Hazard)

• Name/Explanation: Health hazard.
• In Your Own Words: The material can cause long - term or serious health problems (like cancer or organ damage). We should limit exposure, use PPE, and follow safety protocols for handling.

Symbol 8 (Compressed Gas)

• Name/Explanation: Compressed gas.
• In Your Own Words: The material is a gas under pressure. We should handle the container carefully to prevent leaks or ruptures, and store it in a well - ventilated area.

Symbol 9 (Acute Toxicity)

• Name/Explanation: Harmful or fatal – acute toxicity.
• In Your Own Words: The material can cause immediate harm or death if ingested, inhaled, or touched. We should handle it in a fume hood, use PPE, and have emergency procedures in place.

Final Matching Table
