What should be regularly inspected to ensure safe oxyfuel cutting operations?

Regular inspection of the hoses and connections is crucial for ensuring safe oxyfuel cutting operations because these components are directly involved in the delivery of gases to the torch. Over time, hoses can develop leaks due to wear, abrasion, or exposure to heat. Similarly, connections can become loose or corroded, which may lead to dangerous gas leaks.

By consistently checking hoses for cracks, cuts, or signs of deterioration, and ensuring that all connections are tight and secure, operators can significantly reduce the risk of accidents, such as fire or explosion, caused by gas leaks. This practice is a key safety measure in oxyfuel cutting setups, where the integrity of the gas supply system is paramount to safe and efficient operation.

The other options focus on components that, while important, do not encompass the broader aspects of the entire gas delivery system that needs regular checks.
