GRADE 9 Pre-technical – HANDLING WASTE MATERIALS Quiz
1. What is the main reason we should separate different types of waste at the place where it is generated (for example, in a school workshop)?
Separating waste at the source makes it easier to recycle materials, dispose of hazardous items safely and reduce health risks during handling and collection.
2. Which of the following is an example of hazardous waste commonly found in workshops that needs special handling?
Leftover paint and paint thinners contain chemicals that can harm people and the environment and must be stored and disposed of according to safety rules.
3. What is the best immediate action if a classmate gets a cut from a rusty nail while handling scrap material?
Cleaning the wound and getting adult help or medical attention reduces infection risk and ensures proper care such as tetanus protection.
4. Which practice follows the 'Reduce' part of the 3Rs (Reduce, Reuse, Recycle) in a school workshop?
Reducing means using fewer resources and creating less waste, for example by choosing durable tools and buying only what is needed.
5. Why should electronic waste (like old batteries or broken phones) not be thrown with ordinary rubbish?
Electronic waste contains heavy metals and toxic substances; proper recycling or disposal prevents pollution and health hazards.
6. Which is a safe way to store sharp waste (nails, broken glass) before disposal at school?

NEMA and county governments set and enforce waste management regulations in Kenya, while schools must follow these rules.
9. Which of these is an advantage of recycling materials from the school's workshop?
Recycling conserves resources, lowers waste disposal needs and schools can sometimes sell recyclables to raise funds.
10. What is the safest way for students to handle chemical spills from materials like glue or solvents in a workshop?
Chemical spills should be managed by trained staff using PPE and correct methods to avoid harm to people and the environment.
11. Which of the following is the correct description of upcycling?
Upcycling creatively reuses materials to make better or more valuable products, reducing the need for new resources.
12. Why is open burning of plastic waste near the school dangerous?
Burning plastic releases harmful chemicals and particulates that damage lungs, the environment and contribute to pollution.
13. When collecting recyclable paper in school, which practice helps keep it suitable for recycling?
Recyclable paper must be clean and dry; food or oil contamination can make it unusable for recycling.
14. Which of the following items from a workshop should be taken to a hazardous waste collection point rather than the ordinary bin?
Batteries and solvent cans contain hazardous substances that need to be collected and treated separately to avoid pollution.
15. What is a good way for students to help reduce plastic waste at school?
Using refillable bottles and reducing single-use plastics lowers the amount of plastic waste created.
16. How should sharp objects removed from waste be prepared before disposal to protect waste handlers?

Reusing means finding a new purpose for an item rather than discarding it, saving resources and money.
18. Who should students report to if they find illegal dumping of waste near the school grounds?
Reporting to adults and authorities ensures the issue is handled lawfully and safely; students should not try to manage hazardous dumping alone.
19. Which container label best helps with waste segregation at a school workshop?
Clear labels for recyclables, organics and hazardous waste guide correct disposal and make recycling and safe disposal possible.
