Worked Solution & Example Answer:2.1 All personal and environmental safety rules are applicable when a surface grinder is used - NSC Mechanical Technology Automotive - Question 2 - 2017 - Paper 1
Step 1
State THREE safety rules which are only applicable while the surface grinder is in operation.
Answer
-
Ensure that sparks generated during the grinding process do not pose a danger to co-workers.
-
Always bring the material slowly into contact with the grinding wheel to avoid sudden contact.
-
Never attempt to clean or adjust the machine while it is in motion, to prevent accidents.
Step 2
Give TWO reasons why the pressure gauge of a hydraulic press must be tested regularly.
Answer
-
To ensure there are no leaks in the system, which could lead to pressure drops and ineffective operation.
-
To confirm that the gauge readings are accurate, ensuring the hydraulic press functions within the required pressure parameters.
Step 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.
-
Confirm that all electrical parts are properly insulated to prevent electric shock.
-
The operator must be familiar with the equipment and its safe operation to avoid accidents.
Step 4
State TWO safety rules that must be taken into consideration for the safe handling of coil spring compressors.
Answer
-
Ensure that the compressor is strong enough for the spring to prevent breakage and injury.
-
Always use proper protective equipment such as gloves and goggles to safeguard against potential injuries.
