Fire Prevention

When using the Spirit system, it is necessary to exercise good judgment. While cutting,
the arc produces sparks that could cause a fire if they fall on flammable materials.
Make sure that all flammable materials are a suitable distance away from the cutting
area. All flammable liquids should be at least 40 feet away from the cutting area,
preferably stored in a metal cabinet. Plasma cutting should never be attempted on
containers that contain flammable materials. Make sure that fire extinguishers are
readily accessible in the cutting area.
Make sure that the cutting area is properly ventilated when using oxygen as a cutting
gas.

Explosion Prevention

The Spirit system uses compressed gases. Use proper techniques when handling
compressed gas cylinders and other compressed gas equipment.
following guidelines to protect against explosion:
• Never operate the system in the presence of explosive gases or other explosive
materials.
• Never cut pressurized cylinders or any closed container.
• When using a water table and cutting aluminum under water or with water touching
the underside of the aluminum plate, hydrogen gas is produced. This hydrogen gas
may collect under the plate and explode during the cutting process. Make sure the
water table is properly aerated to help prevent the accumulation of hydrogen gas.
• Handle all gas cylinders in accordance with safety standards published by the U.S.
Compressed Gas Association (CGA), American Welding Society (AWS), Canadian
Standards Association (CSA), or other local or national codes.
