BURN SAFETY - Intense ultraviolet light, sparks, and hot metal produced by plasma arc cutting
will harm exposed skin and eyes. Operators and bystanders must wear protective clothing and
equipment to avoid hazards.
EYE SAFETY - Wear appropriate tinted safety goggles with side shields, or a welding helmet to
protect eyes. Refer to the chart for recommended lens or shield shade;
Arc Current Lens/Shield Shade
Up to 100 Amps Shade No. 8
100-200 Amps Shade No. 10
200-300 Amps Shade No. 12
Over 400 Amps Shade No. 14
Do not use eyewear with broken or pitted lenses or covers. Replace them at once.
Post warnings and inform people in the area not to look directly at the arc unless appropriate glasses,
goggles, or a welding helmet is worn.
The Vulcan Operating Area should be adapted to reduce the reflection and transmission of ultraviolet
light. Install protective screens or curtains to reduce ultraviolet transmissions. Paint walls and other
surfaces with dark colors to reduce reflection.
SKIN SAFETY - Always wear protective clothing including, but not exclusive to, gauntlet gloves,
safety shoes, and head covering.
Flame retardant clothing with cuffless trousers to shield body from sparks and slag is strongly
suggested.
After cutting, the sheet edges and the cutting table are dangerously sharp and hot. To avoid cuts and
burns, use heavy gloves to handle pieces during removal.
Never touch the front of the torch when starting it. After cutting has been completed, allow adequate
time for the front of the torch to cool.
Qualified first-aid personnel and facilities should be available at or near any Vulcan site to treat
accidental eye and skin burns at once.
FUME HAZARDS AND PRECAUTIONS - Plasma Arc Cutting vaporizes metals into toxic gases,
so constant ventilation and precautions regarding exposure to the operator or any persons near the
Vulcan are absolutely necessary! An appropriate ventilation system, designed to safely withdraw
toxic fumes from the area, must be installed and used whenever the Vulcan is operated. Do not use
the Vulcan in a confined space unless a safe ventilation system and an operator's fresh air supply
is present and working properly! Refer to Section 1, Preliminary Installation for details regarding the
necessary initial ventilation setups.
Be sure to activate the ventilation system before starting the torch. Check periodically to confirm that
the vent system continues to remove air efficiently! To ensure that it pulls with its greatest force
during cutting, always cover the table top(s) completely, so that air can only flow through a small area
forcing gases into the 12" vent hole. If sheets smaller than 5 x 10' are used, cover excess space on
table top(s) with scrap metal.
Do not cut containers with toxic materials inside or containers that have held toxic materials. Clean
such containers thoroughly before cutting.
