Section 1: Environmental and Safety Considerations in Physics, Part 1 and 2

Question Title

* 2. Why is understanding laboratory risks essential in the physical sciences?

To increase the speed of experiments

To ensure personal and environmental safety

To protect people, the environment, and comply with regulations

To avoid repeating experiments

Question Title

* 3. Which of the following requires environmental and biosafety ethics clearance?

Using deionised water for cleaning glassware

Working with sodium chloride crystals

Handling genetically modified organisms

Measuring melting points of solids

Question Title

* 4. What is the primary purpose of ethical clearance?

To reduce paperwork for researchers

To ensure compliance with safety and environmental standards

To allow unrestricted use of chemicals

To slow down research approval

Question Title

* 5. What is a major hazard in chemistry laboratories?

Dust

Broken electrical cables

Flammable solvents and reactive chemicals

Loud noise from machinery

Question Title

* 6. Which statement about PPE is TRUE?

PPE replaces all other safety procedures

Lab coats are optional when handling solvents

PPE provides the first line of defence against hazards

Gloves are only needed for corrosive compounds

Question Title

* 7. 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

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

To summarise experiment results

To list chemicals used in a project

To give step-by-step safety and handling instructions

To train students in waste recycling

Question Title

* 9. 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

* 10. Why must reducing and oxidising agents be stored separately?

They produce harmless gases

They evaporate quickly

They may react violently or cause fires

They are expensive chemicals

Question Title

* 11. Which of the following gases can cause asphyxiation?

Helium

Nitrogen dioxide

Carbon monoxide

Oxygen

Question Title

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

They are non-reactive elements

They are toxic and bioaccumulate in organisms

They can neutralise acids

They dissolve easily in water

Question Title

* 13. What is the main risk associated with cyanide compounds?

Corrosion

Explosion

Respiratory failure or death

Eye irritation and skin burns

Question Title

* 14. Why should nanoparticles be used in sealed environments?

They lose activity in the open air

They are expensive to produce

They can cause respiratory and cellular damage

They evaporate quickly

Question Title

* 15. 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

* 16. 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

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

Empty reagent bottles

Silica waste

Plastic pipettes

Paper towels

Question Title

* 18. 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

* 19. 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

* 20. What is a good practice for maintaining a chemical inventory?

Keep it private and inaccessible to others

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

Update the list once a year

Record toxic chemicals

Question Title

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

Wait for a supervisor to arrive

Get out immediately

Stay calm and follow emergency procedures

Finish your experiment
