Electrical Safety & Fire Prevention is one of 9 topics in the Grade 10 Agricultural Technology CAPS syllabus, covered across 3 lessons on Study Vault. Below are real practice questions from this topic with full worked answers.
Sample practice questions
Easy
1. Why should electrical equipment never be operated with wet hands or in a wet environment?
Water dramatically increases the conductivity of a path through the body, increasing shock risk
Water has no effect on electrical safety
Wet hands improve grip on electrical equipment with no safety trade-off
Electrical equipment is always waterproof by design
Answer: Water dramatically increases the conductivity of a path through the body, increasing shock risk — Water dramatically increases the conductivity of a path through the body, which is why electrical equipment should never be operated with wet hands or in a wet environment.
Easy
2. What is the first priority when responding to a worker who has sustained an electrical shock and is still in contact with the source?
Switch off or isolate the power source before touching the affected person
Immediately touch and pull the person away with bare hands
Call for help and wait without taking any other action
Pour water on the person to cool them down
Answer: Switch off or isolate the power source before touching the affected person — The power source must be switched off or isolated before touching the affected person, since touching someone still in contact with a live source can pass the current through the rescuer as well.
Medium
3. Name the type of object that can safely be used to push a shock victim away from a live source if the power cannot be quickly switched off.
Answer: a non-conductive object — A non-conductive object, such as a dry wooden pole, can be used to push the person away from the source if power cannot be quickly switched off; metal or wet objects must never be used.
