Noise
Very high frequency and intensity sound is produced when plasma cutting. Exposure
to high levels of noise can cause hearing damage and potentially permanent hearing
loss.
Protect your hearing with appropriate ear defenders or plugs while plasma cutting
particularly at high power levels and in confined spaces
If you are in doubt it is best to measure the level to ensure it is below recommended
levels of exposure
Plasma Arc Ultraviolet Radiation
Plasma arc radiation can burn your eyes and skin, without adequate protection
your eyes and skin are at risk, if exposed your eyesight can be permanently
damaged please ensure you are wearing adequate PPE.
The following should be treated as a guide as to the minimum shade numbers to use for
eye protection while plasma cutting.
