Worked Solution & Example Answer:2.1 All personal and environmental safety rules are applicable when a surface grinder is used - NSC Mechanical Technology Welding and Metalwork - Question 2 - 2017 - Paper 1
Step 1
2.1 All personal and environmental safety rules are applicable when a surface grinder is used. State THREE safety rules which are only applicable while the surface grinder is in operation.
Answer
- Ensure that sparks generated during operation do not pose a danger to co-workers by keeping the work area clear.
- Always bring materials slowly into contact with the grinding wheel to prevent snags and accidents.
- Never clean or adjust the surface grinder while it is in motion to avoid injuries.
Step 2
2.2 Give TWO reasons why the pressure gauge of a hydraulic press must be tested regularly.
Answer
- To ensure that there are no leaks in the hydraulic system, which could lead to pressure loss and operational failures.
- To confirm that the pressure readings are accurate, ensuring safe and efficient operation of the hydraulic press.
Step 3
2.3 State THREE important safety precautions that should be observed before MIG/MAGS welding is done.
Answer
- Ensure that the working area is well ventilated to prevent the accumulation of harmful fumes.
- Make sure that electrical parts are properly insulated to avoid electrical hazards.
- The operator should be familiar with the equipment to ensure proper and safe usage.
Step 4
2.4 State TWO safety rules that must be taken into consideration for the safe handling of coil spring compressors.
Answer
- Ensure the compressor is strong enough for the spring being handled to prevent failure during the compression.
- Always handle the spring carefully and ensure it is secured properly to prevent it from escaping or causing injury.
