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 be highly flammable and may lead to dangerous explosions if they come into contact with the high-pressure gas. The buildup of oil or grease can also impair the proper functioning of the regulator, leading to unsafe conditions.
Step 2
Name THREE safety precautions when handling or using the gas cylinders.
Answer
- Always secure gas cylinders upright to prevent them from falling.
- Ensure that the inspection date of the cylinders is current and check for any damage before use.
- Use proper personal protective equipment (PPE), such as gloves and goggles, when handling cylinders.

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 starting the machine to avoid any unintended movement.
2.4.2 Machine guard: Make sure the guard is well secured before switching on the machine and ensure it is in good condition to prevent accidents.
2.4.3 Chuck: Keep hands away from the rotating chuck and ensure the chuck is well secured before operation. Always turn the chuck manually to confirm no part of the workpiece can strike any part of the lathe.
