Dust

Question Title

9. Which statement about PPE is TRUE?

Gloves are only needed for corrosive compounds

PPE provides the last line of defence against hazards

Lab coats are optional when handling solvents

PPE replaces all other safety procedures

Question Title

10. What key information does a safety data sheet (SDS) provide?

Names of researchers who designed the chemical

Hazards, handling, and first aid measures

Chemical supplier details

The molecular structure of the chemical

Question Title

11. What is the purpose of a standard operating procedure (SOP)?

To train students in waste recycling

To give step-by-step safety and handling instructions

To list chemicals used in a project

To summarise experiment results

Question Title

12. What is the correct practice when diluting acids?

You can use a metal container for mixing

Add both at the same time

Add acid to water slowly

Add water to acid

Question Title

13. Why must reducing and oxidising agents be stored separately?

They are expensive chemicals

They may react violently or cause fires

They evaporate quickly

They produce harmless gases

Question Title

14. Which of the following gases can cause asphyxiation?

Helium

Nitrogen dioxide

Carbon monoxide

Oxygen

Question Title

15. Why are heavy metals such as mercury and lead of environmental concern?

They dissolve easily in water

They can neutralise acids

They are toxic and bioaccumulate in organisms

They are non-reactive elements

Question Title

16. What is the main risk associated with cyanide compounds?

Eye irritation and skin burns

Respiratory failure or death

Explosion

Corrosion

Question Title

17. Why should nanoparticles be used in sealed environments?

They evaporate quickly

They can cause respiratory and cellular damage

They are expensive to produce

They lose activity in the open air

Question Title

18. Which practice helps protect against radiation exposure?

Wearing thick gloves

Using shielding, minimising exposure time, and maintaining distance

Coming closer to inspect the source

Turning off warning signs

Question Title

19. When classifying chemical waste, how should mixtures be treated?

By the size of the container

By colour of the waste

Based on the most hazardous component

Based on the least hazardous component

Question Title

20. Which of the following should be disposed of in a separate, labelled container?

Paper towels

Plastic pipettes

Silica waste

Empty reagent bottles

Question Title

21. Which of the following is correct about fume cupboard use?

Keep the sash fully open at all times

Place equipment at the front edge

Keep materials at least 15 cm inside the hood

Store chemicals inside when not in use

Question Title

22. Why should incompatible chemicals not be stored together?

They may evaporate faster

They can react dangerously, causing fires or explosions

They occupy too much space

They become less reactive

Question Title

23. What is a good practice for maintaining a chemical inventory?

Record toxic chemicals

Update the list once a year

Update it whenever chemicals are received, used, or disposed of

Keep it private and inaccessible to others

Question Title

24. What is the first action to take during a laboratory emergency?

Finish your experiment

Stay calm and follow emergency procedures

Get out immediately

Wait for a supervisor to arrive
