Instructions for nondestructive testing personnel?

What are the precautions for nondestructive testing workers?

The lines of flaw detection instruments and auxiliary electrical equipment should be insulated, and the shell should be reliably grounded. When overhauling, the power supply should be cut off first.

X-ray flaw detection operators should regularly check their health. Protective equipment must be worn at work.

Fences and warning signs should be set up at the X-ray inspection work site.

When X-ray inspection, you should evacuate quickly. Mechanical operation should be used when exploring photos, and it is forbidden to touch the radiation source with your hands.

For X-ray flaw detection, there should be lead protective screen or other protective measures. Before exposure, the operator should deviate from the "window" of the X-ray machine, and the exposure should be carried out after the personnel arrive at the safe area.

After the ultrasonic instrument is electrified, it is forbidden to open the protective cover to prevent high-voltage electricity from hurting people.

Protective glasses should be worn during fluorescence penetrant inspection. It is forbidden to directly touch the fluorescent powder and developing powder on the workpiece by hand. The preparation of color flaw detector or the screening of fluorescent powder, magnetic powder and developing powder should be carried out in a well-ventilated place.
