Precautions against fire and explosion
Avoid causing fires due to sparks and hot waste or molten metal.
Ensure that appropriate fire safety devices are available near the welding and
cutting area.
Remove all flammable and combustible materials from the welding, cutting and
surrounding areas.
Do not weld or cut fuel and lubricant containers, even if empty. These must be
carefully cleaned before they can be welded or cut.
Always allow the welded or cut material to cool before touching it or placing it in
contact with combustible or flammable material.
Do not work in atmospheres with high concentrations of combustible fumes,
flammable gases and dust.
Always check the work area half an hour after cutting to make sure that no fires
have begun.
Take care to avoid accidental contact of electrode to metal objects. This could
cause arcs, explosion, overheating or fire.
Risks due to hot material ·
The process will create hot metal, sparks and drips of molten metal, so it's very
important to ensure the operator is equipped with full PPE and to always ensure
there are adequate protective screens or barriers to protect others from flash,
glare and sparks from the working area. Hot surfaces will create fires and will
burn any exposed skin.
Always protect your eyes and body. Use the correct welding screen and filter
lens and wear full PPE protective clothing.
Do not touch any hot surfaces or parts bare handed.
Always allow hot surfaces and parts to cool down first before touching or
moving.
If you are required to move hot parts, ensure you use proper tools and insulated
welding gloves (PPE) to prevent burns to your hands and arms.

Noise——Excessive noise may be harmful to hearing
·Protect your ears by ear shields or other hearing protectors.
·Give warning to nearby personnel that noise may be potentially
hazardous to hearing.
Risks due to magnetic fields
The magnetic fields created by high currents may affect the operation of
pacemakers or electronically controlled medical equipment.
Wearers of vital electronic equipment should consult their physician before
beginning any arc welding, cutting, gouging or spot welding operations.
Do not go near welding equipment with any sensitive electronic equipment as
the magnetic fields may cause damage.
Keep the torch cable and work return cable as close to each other as possible
throughout their length, this can help minimize your exposure to harmful
magnetic fields.
Do not wrap the cables around the body.
