Worked Solution & Example Answer:2.1 Name any TWO pieces of personal safety equipment that you need to wear when working with an angle grinder - NSC Mechanical Technology Fitting and Machining - Question 2 - 2018 - Paper 1
Step 1
Name any TWO pieces of personal safety equipment that you need to wear when working with an angle grinder.
Answer
When working with an angle grinder, it is essential to wear the following pieces of personal safety equipment:
-
Safety goggles or face shield – These protect your eyes and face from flying debris and sparks.
-
Ear protection (ear plugs or muffs) – This is crucial to prevent hearing damage from the loud noise of the grinder.
Step 2
State THREE safety precautions you should observe before pressing a bearing from a shaft on a hydraulic press.
Answer
Before pressing a bearing from a shaft on a hydraulic press, ensure to observe these safety precautions:
-
Check the pressure gauge - Ensure that the pressure gauge is in working order and the pressure does not exceed the prescribed limits for the operation.
-
Secure the workpiece - Make sure the workpiece is securely fastened and that any clamping devices are properly in place to prevent movement during pressing.
-
Inspect for hazards - Examine the hydraulic press for any potential hazards, such as leaks in the hydraulic pipes or issues with the apparatus that could endanger operators.
Step 3
Why is it important to wear an arc-welding helmet/shield during arc welding?
Answer
Wearing an arc-welding helmet/shield is important for the following reasons:
-
Protection from ultra-violet rays - The helmet shields your skin and eyes from harmful UV radiation produced during welding.
-
Debris protection - It provides protection for your face from sparks and molten metal while chipping the slag after welding.
Step 4
State TWO safety precautions that should be adhered to before you start working on a milling machine.
Answer
Before starting work on a milling machine, adhere to these precautions:
-
Clamp workpieces securely - Always ensure that workpieces and clamping devices are properly secured to prevent movement during operation.
-
Check guards - Ensure that all guards are in place and functional to protect against accidental contact with moving parts.
Step 5
What safety aspect must be executed before leaving ANY machine after completing a given task?
Answer
Before leaving any machine, it is crucial to ensure that the machine is turned off completely and that all moving parts have come to a full stop. This prevents accidents and ensures safety for the next operator.
Step 6
State ONE safety precaution you should observe when using a spring compressor to remove a coil spring from a motor vehicle's suspension.
