Worked Solution & Example Answer:2.1 State the reason why oil and grease should never be used on or near the regulator of oxy-acetylene equipment - NSC Mechanical Technology Welding and Metalwork - Question 2 - 2017 - Paper 1
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 when in contact with the high-pressure oxygen environment, leading to explosive reactions. This poses a significant risk of fire and severe injury.
Step 2
Name THREE safety precautions when handling or using the gas cylinders.
Answer
-
Always secure gas cylinders in an upright position to prevent them from falling.
-
Ensure that the regulator is in good condition and properly fitted before use.
-
Use the correct transport methods, such as a cylinder cart, to move gas cylinders safely.
Step 3
Name THREE safety precautions when handling or using the gas cylinders.
Answer
-
Always check for leaks in the gas cylinder before use by applying soapy water to the fittings and observing for bubbles.
-
Keep the cylinder away from heat sources, as exposure can increase pressure and risk of explosion.
-
Store gas cylinders in a well-ventilated area to avoid the accumulation of any gas leaks.
