How should welding cylinders be moved safely?

• Using a dolly or hand truck
• By a minimum of two people
• Rolling them across the floor
• By tilting and rolling them on their bottom edges

Correct Answer

• By tilting and rolling them on their bottom edges

Explanation Welding cylinders can be moved by tilting and rolling them on their bottom edges. This method allows for easier transportation as the cylinders can be tilted onto their edges and then rolled along the floor. This technique is commonly used because it requires less effort compared to other options such as using a dolly or hand truck, or having a minimum of two people to lift and carry the cylinders. Rolling the cylinders across the floor is also a feasible method, but tilting and rolling them on their bottom edges is generally preferred for convenience and efficiency.

What is the minimum height above the floor for refrigerant piping that crosses an open space?

• 6'6"

This requirement helps prevent potential damage to the piping and ensures that people can pass through the area without obstruction.
