Recommended Safety Precautions
2.1
Health Hazard Information
The actual process of welding is one that
can cause a variety of hazards. All appropriate safety
equipment should be worn at all times, i.e. headwear,
respiratory, hand and body protection. Electrical equipment
should be used in accordance with the manufacturer's
recommendations.
Eyes
The process produces ultra violet rays that can injure and cause
permanent damage. Fumes can cause irritation.
Skin
Arc rays are dangerous to uncovered skin.
Inhalation
Welding fumes and gases are dangerous to the health of the
operator and to those in close proximity. The aggravation
of pre-existing respiratory or allergic conditions may occur
in some workers. Excessive exposure may cause conditions
such as nausea, dizziness, dryness and irritation of eyes, nose
and throat.
2.2 Personal Protection
Respiratory
Confined space welding should be carried out with the aid of
a fume respirator or air supplied respirator as per AS/NZS 1715
and AS/NZS 1716 Standards.
You must always have enough ventilation in confined spaces. Be
•
alert to this at all times.
Keep your head out of the fumes rising from the arc.
•
Fumes from the welding of some metals could have an adverse
•
effect on your health. Don't breathe them in. If you are welding
on material such as stainless steel, nickel, nickel alloys or
galvanised steel, further precautions are necessary.
Wear a respirator when natural or forced ventilation is not good
•
enough.
Eye protection
A welding helmet with the appropriate welding filter lens
for the operation must be worn at all times in the work
environment. The welding arc and the reflecting arc flash gives
out ultraviolet and infrared rays. Protective welding screen
BOC RAPTOR 200C & 250R MIG Operating manual
and goggles should be provided for others working in the
same area.
Recommended filter shades for arc welding
Less than 150 amps
150 to 250 amps
250 to 300 amps
300 to 350 amps
Over 350 amps
*Use one shade darker for aluminium
Clothing
Suitable clothing must be worn to prevent excessive exposure
to UV radiation and sparks. An adjustable helmet, flameproof
loose fitting cotton clothing buttoned to the neck, protective
leather gloves, spats, apron and steel capped safety boots are
highly recommended.
