CSA standard W117.2-12 (R2017) - Safety in welding, cutting, and allied processes and ANSI (American National Standards Institute) standard Z49.1: 2021Safety in Welding, Cutting and Allied Processes were created to protect persons and property from injury, illness, and damage from fire and explosions that may occur from these processes.
CCOHS: Welding - Ergonomics
Select matte finishes for welding area to avoid reflection of welding arc light and to obtain a satisfactory level of lighting. Choose any colour except blue or turquoise; they reflect UV light. Reduce distraction by making piping, ducting or structural supports the same colour as the background unless piping requires colour coding due to its ...
Welding - Storage and Handling of Compressed Gas Cylinders
2024年5月10日 · Always check for leaks before using the welding system, after shutting it down, and before transporting cylinders. Use commercial leak detection products for a leak test that is specified in the safe operating procedure or on the safety data sheet. These solutions must be compatible with the gas being checked.
