Welding is the most common method of joining metals in industry today. When welded, two pieces of similar metals are fused (melted) together. Once completed,
the welded joint is as strong or stronger than the pieces from which the joint is formed.
WHAT IS WELDING?
General hazards of welding include impact, penetration, harmful dust, smoke, fumes, heat and
light radiation, whether it be arc or gas welding. The dangers are real and you will need to take
appropriate action to keep yourself and other safe.
Welding is considered a high risk activity, especially when conducted in an operating plant. There are however several lines of defense to reduce the risks
significantly. These would include…

LINES OF DEFENSE
Training and competencies.
Including Company and
Client Inductions
/HIRA/Medical Fitness/
Task Specific Risk
Assessment - and
communication of risks to employees
Physical Barriers –
Barricading/Spark
Containment/Warning
signs/Welding screens etc.
Permit to Work System – Ensure compliance to
permit requirements
through continuous monitoring.
Communication and interfacing -
with people affected by your
activities.
Continuous risk assessment. –
Daily Task Instructions/PTO’

s
PPE – Welding helmets, Aprons, Spats, welding
gloves etc.
Supervision – Competent,
trained supervision on
site.
Emergency Preparedness –
Know the emergency
procedures.

PPE REQUIRED
A welding helmet will protect your eyes and face
from the harmful effects of welding
Burns to the cornea of the eyes. Also known
as “arc eyes”
Second degree burns to the neck and face.

Welding gloves are thick, heat
resistant gloves with long cuffs to
protect your hands and lower arms.
This person decided to weld without welding gloves.
Burns to his hand due to prolonged exposure
to the UV rays produced by welding.
A welding apron is made of leather and protects you
body from any hot metal that might
fall onto you
This person decided to weld without a welding apron.

Leg covers, also known as spats prevent any hot metal to fall onto
or into your shoes.
A piece of hot metal fell into his safety shoe and
he sustained a 3rd degree burn.
This person decided not to wear leg covers while welding
Remember that PPE is only useful when YOU make the decision to use it properly. The

OTHER CONSIDERATIONS
Spark containment and protecting other people from the affects of welding is very
important. Use welding screens or fire blankets to ensure the safety of yourself
and those around you..

Sewers are identified as places where explosive gases or materials could be present. Make sure that if you need to conduct hot work close to sewer systems that you cover them with a fire blanket. Also make sure that gas readings are
taken and NEVER dispose of any chemicals into any sewer.
