Protection Against Fumes And Gases; Fire/Explosion Prevention; Prevention When Using Gas Cylinders; Protection From Electrical Shock - Inteco HARRIER 280 Instrucciones De Uso

Ensure the cooling unit is switched off before dis-
connecting the pipes of the cooling liquid. The hot
liquid coming out of the pipes might cause burning
or scorching.
Keep a first aid kit ready for use.
Do not underestimate any burning or injury.
Before leaving work, make the area safe, in order
to avoid accidental damage to people or property.

1.3 Protection against fumes and gases

• Fumes, gases and powders produced during the welding
process can be noxious for your health.
Under certain circumstances, the fumes caused by welding
can cause cancer or harm the foetus of pregnant women.
• Keep your head far from any welding gas and fumes.
• Provide for proper ventilation, either natural or forced, in the
work area.
• In case of poor ventilation, use masks and breathing apparatus.
• In case of welding in extremely small places the work should
be supervised by a colleague standing nearby outside.
• Do not use oxygen for ventilation.
• Verify the fumes extractor is working by checking regularly the
quantity of harmful exhaust gases versus the values stated in
the safety regulations.
• The quantity and the danger level of the fumes depends on
the base material used, the filler material and on any sub-
stances used to clean and degrease the pieces to be welded.
Follow the manufacturer's instructions together with the
instructions given in the technical sheets.
• Do not perform welding operations near degreasing or paint-
ing stations.
Position gas cylinders outdoors or in places with good ventila-
tion.

1.4 Fire/explosion prevention

• The welding process may cause fires and/or explosions.
• Clear the work area and the surrounding area from any flam-
mable or combustible materials or objects.
Flammable materials must be at least 11 metres (35 feet) from
the welding area or they must be suitably protected.
Sparks and incandescent particles might easily be sprayed
quite far and reach the surrounding areas even through
minute openings. Pay particular attention to keep people and
property safe.
• Do not perform welding operations on or near containers
under pressure.
• Do not perform welding operations on closed containers or
pipes.
Pay particular attention during welding operations on tubes
or containers even if these are open, empty and have been
cleaned thoroughly. Any residue of gas, fuel, oil or similar
materials might cause an explosion.
