Correct Answer:
A. Inspect for gas leaks, ensure pressure gauges are functional, check the integrity of hoses, and verify that regulators are properly calibrated.
Explanation:
- A. Correct: Safety checks for oxy-acetylene welding include inspecting for gas leaks, ensuring pressure gauges are operational, checking hoses for wear or damage, and verifying that regulators are correctly calibrated. These steps are essential for safe and effective welding.
- B. Incorrect: While checking for gas leaks and ensuring the proper condition of hoses is relevant, painting for visibility and checking gas levels or hose colors are not standard safety inspections.
- C. Incorrect: Heating the torch is not a pre-welding safety check, and cylinder color is not a safety feature. Checking for kinks in hoses is important but does not encompass the full range of necessary inspections.
- D. Incorrect: Automatic shut-off features are not standard for all torches, checking cylinder labels alone does not cover all safety features, and hose length is less relevant than hose condition and integrity.
