A frayed cord is an electrical hazard; the correct action is to stop use, tag or isolate the tool and report so it can be repaired or replaced safely.

3. What is the main purpose of machine guards on workshop equipment?

To increase the machine's speed
To make it easier to clean the machine
To prevent contact with moving parts and reduce risk of injury
To make the machine look complete
Explanation:

Guards are safety devices designed to keep hands, clothing and other objects away from moving parts that could cause cuts, entanglement or crushing injuries.

4. Before starting maintenance on a machine you should always:

Turn it off and leave it as is
Disconnect tools only after finishing work
Isolate and lock out the energy source (lockout-tagout) and ensure the machine cannot start
Hold down the start button while working
Explanation:

Lockout-tagout prevents accidental energising of equipment during maintenance, protecting workers from unexpected start-up and energy release.

5. Which extinguisher is most appropriate for putting out an electrical fire in the workshop?

Garden hose
Water bucket
Carbon dioxide (CO2) or dry powder extinguisher
Wet cloth
Explanation:

Water conducts electricity and should not be used on electrical fires; CO2 or dry powder extinguishers are suitable because they do not conduct electricity and smother the fire.

6. What should you do if someone in the workshop receives a deep cut and is bleeding heavily?

Pour water over the wound and walk away
Try to remove any embedded objects from the wound immediately
Apply direct pressure with a clean cloth, raise the limb if possible and seek first aid help
Leave them alone to rest until the bleeding stops
Explanation:

Direct pressure and elevation help control bleeding while you summon trained first aid or medical care; removing embedded objects can cause more damage.

7. Why must the workshop floor be kept clean and free of oil spills and debris?

To prevent slips, trips and falls and to keep a safe working area
So tools do not get dirty
To make cleaning easier at the end of term
Because it looks nice for visitors only
Explanation:

Good housekeeping reduces the risk of accidents such as slips or trips which are common causes of injury in workshops.

8. Which of these is the correct way to lift a heavy object safely?

Lift quickly using only your arms
Twist your body while lifting to save time
Keep your legs straight and bend your back to lift
Bend your knees, keep your back straight and lift with your legs
Explanation:

Lifting with the legs and keeping the back straight reduces strain on the spine and lowers the risk of back injury.

9. What should you do if you smell gas or see a fuel leak in the workshop area?

Ignore it if it is faint
Turn off sources of ignition, ventilate the area, evacuate and report the leak immediately
Light a match to see where the smell is coming from
Spray water over the area
Explanation:

Gas or fuel leaks are fire and explosion hazards; removing ignition sources, ventilating, evacuating and reporting ensures safety and allows professionals to handle it.

10. Which of the following is NOT allowed in the workshop?

Wearing safety boots when using machines
Using appropriate PPE for tasks
Horseplay and running between machines
Following supervisor instructions
Explanation:

Horseplay increases the risk of accidents near dangerous equipment; it is strictly prohibited in workshops while wearing PPE and following instructions are required.

11. When using compressed air to clean a bench or clothing you should:

Never direct compressed air at people and use it only with proper nozzles and reduced pressure
Blow it directly into your clothing to remove dust
Use the highest pressure available for faster cleaning
Point it at others to help them clean
Explanation:

Compressed air can force particles into the skin or eyes and cause serious injury; use safe nozzles, reduced pressure and never direct it at people.

12. Why must flammable liquids be stored in a designated, labelled cabinet?

Because liquids must be hidden
To keep them out of sight of students only
To reduce fire risk and prevent accidental exposure or ignition
So they mix with other chemicals
Explanation:

Storing flammables in a proper cabinet reduces the chance of fire, limits vapor release and ensures appropriate separation from ignition sources.

13. What is the correct action if you are unsure how to operate a piece of equipment?

Let a friend show you without supervision
Ask the instructor or a qualified person for instruction before using it
Read random online posts instead of asking
Try to use it and learn by trial and error
Explanation:

Proper instruction ensures safe operation and helps prevent accidents caused by incorrect use; never operate unfamiliar equipment without guidance.

14. Which clothing is unsafe in the workshop?

Well-fitted coveralls and safety boots
Gloves suitable for the task
Short hair tied back or hair net
Loose-fitting clothes, jewellery and long hanging sleeves
Explanation:

Loose clothing and jewellery can get caught in moving machinery; wearing fitted protective clothing prevents entanglement hazards.

15. What should you do with broken tools or parts you find in the workshop?

Keep using them until they fail completely
Report them and place them in a designated area for repair or disposal
Hide them to avoid trouble
Throw them into the general waste bin outside immediately
Explanation:

Broken tools are unsafe; reporting and segregating them prevents further use and allows proper repair or disposal following workshop rules.

16. Why is it important to have emergency exits and routes kept clear at all times?

So everyone can leave quickly and safely during an emergency
Because they look neat
To store extra materials near the exits
So teachers can block routes when needed
Explanation:

Blocked exits slow evacuation and increase risk during fires or other emergencies; clear routes are essential for safe escape.

17. What should visitors or new students do when they enter the workshop?

Wait outside without telling anyone
Start using tools if they look easy
Report to the supervisor, receive safety briefing and wear required PPE
Wander around to find interesting tools
Explanation:

Supervision and a safety briefing ensure visitors understand hazards and wear appropriate PPE so they remain safe in the workshop.

18. Which sign indicates that hearing protection must be worn in a certain area?

A green first aid cross
A sign that says 'no food allowed'
A symbol of ear defenders or an ear with sound waves and the words 'hearing protection required'
A picture of a fire extinguisher
Explanation:

Hearing protection signs use recognizable ear or ear-defender symbols to show areas where noise levels require ear protection for safety.

19. When performing welding, what is an essential safety precaution?

Weld in a crowded area for supervision
Stand directly under the welding arc without mask
Wear a certified welding mask, gloves and use proper ventilation or fume extraction
Only wear sunglasses and a short sleeve shirt
Explanation:

Welding produces bright light, sparks and harmful fumes; a welding mask protects eyes and face, gloves protect hands and ventilation removes fumes.

20. What is the correct procedure after an accident that causes injury in the workshop?

Report the incident to the supervisor immediately and complete an accident report
Only tell friends and not the teacher
Try to hide what happened to avoid blame
Ignore it if the injury seems small
Explanation:

Timely reporting ensures injured persons get proper care and helps the workshop address hazards to prevent future incidents.

21. How should corrosive chemicals be handled and stored in the workshop?

Mixed with other chemicals to save space
In labelled containers, with protective PPE, and stored in a separate, ventilated area
Poured into regular bins after use
Left open on workbenches
Explanation:

Correct labelling, PPE and separate storage reduce the risk of chemical burns, inhalation and dangerous reactions with other substances.

22. Why must you secure a workpiece properly before using a drill or lathe?

So the machine will use more power
Because it looks professional
To prevent the workpiece from moving, which could cause injury or poor workmanship
To reduce the noise only
Explanation:

A loose workpiece can spin, be thrown or cause cutters to bite unexpectedly; secure clamping ensures safety and accuracy.

23. What is the safest action when you notice a small fire starting in a waste bin?

Throw water on it without thinking about materials involved
Raise the alarm, use the correct type of extinguisher if trained, and evacuate if it grows
Try to beat it with bare hands
Leave it and continue working
Explanation:

Quickly alerting others and using the right extinguisher can control small fires; if unsure or if the fire spreads, evacuate and call for help.

24. What is the reason for wearing safety boots in the workshop?

Because trainers are not allowed
To protect feet from heavy falling objects, sharp items and electrical risks
To keep feet warm only
To be fashionable
Explanation:

Safety boots have reinforced toes and soles that protect feet from impacts, punctures and sometimes electrical hazards common in workshops.

25. If a chemical label shows a hazard symbol and you do not know what it means, you should:

Use it carefully without further information
Pour it into the sink to see its reaction
Consult the Safety Data Sheet (SDS) or ask the supervisor before use
Mix it with water to reduce hazard
Explanation:

An SDS provides information on hazards, first aid and safe handling; always check it or ask a supervisor to avoid dangerous exposures.

26. What should you do with oily rags and cloths used in the workshop?

Store them in a cardboard box near the heater
Burn them immediately in the workshop
Place them in a designated metal container with a lid to prevent spontaneous combustion
Throw them on the floor to dry
Explanation:

Oily rags can self-heat and ignite; storing them in a closed metal container reduces oxygen supply and the risk of spontaneous combustion.

27. Why must mobile phones and earphones often be restricted during practical workshop sessions?

Because they are expensive
So students can talk loudly
Because they can distract users and reduce awareness of hazards and instructions
To make the workshop quiet only
Explanation:

Distractions from phones or earphones reduce concentration and hearing of warnings, increasing the chance of accidents around machinery.
