HEAT
Plasma arc cutting creates a Heat-Affected Zone (HAZ) around the cut edge of the
workpiece. Until the hot edges cool, the HAZ will burn an unprotected hand
severely.
1. When removing produced parts or skeletons from the machine, operators should
wear heat-resistant, gauntlet-type gloves.
2. The torch, cutter bars, ducting, and dust collector become hot during torch
cutting. Avoid contact with these components unless you are wearing
heat-resistant gloves.
NOISE
The noise levels generated during plasma arc cutting may be as high as 105
decibels. This depends on the distance from the machine, arc, plasma torch nozzle
design, gas velocity, material type, and plate thickness. Piranha recommends that
each user check the sound levels in his own shop under normal operating
conditions.
Based on those findings, provide adequate ear protection to all personnel who must
work near the machine, in accordance with applicable local, state, and federal
industry standards.
NOTE: Noise levels that can cause discomfort or damage to hearing will
vary greatly from one individual to another. Piranha recommends
that ear protection be furnished to any worker who requests it,
regardless of applicable industrial standards or tested noise levels.
WARNING
Exposure to noise from the cutting process can damage hearing.
Wear appropriate ear protection when operating the machine or
when working in the proximity of the machine.
