NOISE CAN DAMAGE HEARING

Pacemaker and hearing aid operation can be affected by

magnetic fields from high currents.
Pacemaker and hearing aid wearers should consult a

doctor before going near any plasma arc cutting and

gouging operations.
To reduce magnetic field hazards:
• Keep both the work cable and the torch lead to one

side, away from your body.

• Route the torch leads as close as possible to the

work cable.

PACEMAKER AND HEARING AID OPERATION

Cutting with a plasma arc can exceed acceptable noise

levels as defined by local codes in many applications.

Prolonged exposure to excessive noise can damage

hearing. Always wear proper ear protection when cutting

or gouging, unless sound pressure level measurements

taken at the installed site have verified personal hearing

protection is not necessary per relevant international,

regional, and local codes.
Significant noise reduction can be obtained by adding

simple engineering controls to cutting tables such as

barriers or curtains positioned between the plasma arc

and the workstation; and/or locating the workstation

away from the plasma arc. Implement administrative

controls in the workplace to restrict access, limit

operator exposure time, screen off noisy working areas

and/or take measures to reduce reverberation in working

areas by putting up noise absorbers.

Use ear protectors if the noise is disruptive or if there

is a risk of hearing damage after all other engineering

and administrative controls have been implemented.

If hearing protection is required, wear only approved

personal protective devices such as ear muffs or ear

plugs with a noise reduction rating appropriate for the

situation. Warn others in the area of possible noise

hazards. In addition, ear protection can prevent hot

splatter from entering the ear.

Frozen pipes may be damaged or can burst if you attempt to thaw them with a plasma torch.

A PLASMA ARC CAN DAMAGE FROZEN PIPES

• Do not wrap or drape the torch lead or work cable

around your body.

• Keep as far away from the power supply as possible.
