Step 1
State the reason why oil and grease should never be used on or near the regulator of oxy-acetylene equipment.
Answer
Oil and grease can ignite in the presence of oxygen, potentially causing explosions or fires. Therefore, it is critical to keep these substances away from oxy-acetylene equipment to ensure safety.
Step 2
Name THREE safety precautions when handling or using the gas cylinders.
Answer
- Always secure the cylinders in an upright position to prevent tipping.
- Use appropriate personal protective equipment (PPE) such as gloves and goggles when handling the cylinders.
- Ensure that the area is well-ventilated to avoid the accumulation of flammable gas.
Step 3
List TWO precautions you would take when welding using the MAGS/MIGS welding machine.
Answer
- Always wear appropriate PPE, including a welding helmet and protective clothing, to safeguard against sparks and UV radiation.
- Make sure the work area is free of flammable materials to reduce the risk of fire.
Step 4
Which safety precautions should be observed when working on the following parts of a lathe:
Answer
2.4.1 Tailstock: Ensure that the tailstock is properly secured before operating the lathe to prevent movement.
2.4.2 Machine guard: Make sure the guard is well secured before switching on the machine and check that it is in good condition.
2.4.3 Chuck: Keep hands away from the rotating chuck, do not leave the chuck key in the chuck, and turn the chuck by hand to verify that there is no danger of the workpiece striking any part of the lathe.
