Sparks
Sparks form as the plasma arc torch vaporizes metal. These sparks are tiny
droplets of extremely hot molten metal and are a possible fire hazard. The volume
of sparks formed and the area over which they are scattered depend on several
variables. These variables include the type and thickness of the material being cut,
the cutting current, and the feed rate. Where practical, keep all combustible material
at least 35 ft. (10.7 m) away from the plasma arc work area. Where this is not
practical, protect all combustible materials with close fitting, flame proof covers or
shields. Protect wooden or other combustible floors by covering them with sand or
installing fire-resistant shields. Shield any wall openings, floor openings, cracks,
ducts, or conveyors within 35 ft. (10.7 m) of the torch to prevent sparks from passing
into adjacent areas.
WARNING
Sparks from the cutting process may ignite flammable items in the
machine bed which may then be drawn into the extraction unit,
possibly causing a fire.
NOTE: Be sure to use an approved facemask and approved eye protection
when cleaning or servicing the dust collector.
NOTE: Plasma arc cutting systems can produce large volumes of fumes. If
you exhaust fumes to the outside atmosphere, additional air
pollution control devices may be in order to conform to local, state,
and federal government ordinances. Air pollution control devices
are the responsibility of each individual user.
Internal Ventilation System
Due to the noxious and toxic nature of many torch cutting by-products, Piranha
recommends venting the machine's internal ventilation system (referred to as the
"dust collector") to the outside atmosphere. This recommendation is especially
important when the shop has one of the following:
1. Low ceilings and/or confined area
2. Large amount of welding and/or torch cutting near the plasma system
3. Poor cross plant ventilation
