Guard Inspection and Tool Use

Ensure guards are tight and if cracked or missing, stop using them immediately and replace them.
Tools used such as hammers and flat shovels should not be hardened too much to prevent injuries from shattering on impact.
When using a hand cone, you need to observe the surrounding area for people or obstacles.
After replacing the new grinding wheel piece should be tightened and confirmed to be safe before use.
When working with a welder, the grinder should guard against arc light so as not to sting the eyes.
No welding equipment shall be moved.
Before operating on the line must wear glasses, dust masks and other labor protection products.
Precautions for gas cutting process

During the cutting process before gas cutting, sheet metal processors need to pay attention to adjusting the preheating flame to maintain a neutral flame or a slight oxidizing flame. The distance between the tip of the flame core and the surface of the cut piece is preferably maintained at three to five millimeters.
The center of the cutting oxygen channel should be aligned with the edge of the plate to help reduce slag splatter.
During gas cutting, care is taken to adjust the distance between the cutting nozzle and the cutting surface and the tilt angle of the cutting nozzle, as well as to adjust the gas cutting oxygen pressure and control the cutting speed to ensure the safety of the gas cutting process.
Welding and joining position processing

When using the welding joint cutting drill, be careful not to drill the underlying steel plate. After the cutting is completed, the residual weld joints should be completely knocked out before assembling the new plate.
Treat the joints of the beams before welding to prepare them for shielded welding.
Pay attention to the size of the holes when opening them.
When removing the paint film, be careful not to damage its galvanized layer.
Other Precautions

When using electric high-frequency equipment, avoid people in the direction of grinding to prevent injury.
