V1.1
2. Avoid positions that allow welding fumes to reach your face. Always attempt to weld 'upwind'
of the workpiece with the airflow across the face of the welder. Airflow from behind may create
a low-pressure area in front of the welder and draw the fumes to the person.
3. Ventilate the work area to remove welding fumes and gases. The fumes and gases should
be drawn away from the user.
3.1 Ventilation should be enough to disperse fumes, but not enough to disturb the
shielding gas or flame during welding.
3.2 Ventilation exhaust shall be directed to a non-work area to avoid exposing other people
to potential toxic or dangerous fumes.
3.3 Air removed from the work area by the ventilation system must be replenished with fresh
air to avoid oxygen starvation or a build-up of fumes or gases. Only use air to provide
ventilation. Any other combination of gases may be explosive or toxic to people in the
work area.
3.4 Ventilation methods that remove gas and fumes from the welding point before they
reach the welder's face should be given preference.
4. Avoid welding in a work area that has vapours from cleaning, degreasing or any spraying
operations. The heat and light from welding can react with the vapour and form irritating or
potentially toxic gases. Wait for the vapours to disperse.
5. Consult the manufacturer's Safety Data Sheets (SDS) for instructions and precautions
about metals, consumables, coatings, cleaners and degreasers.
5.1 Do not weld on coated metals such as galvanized, lead or cadmium plated steel, unless
the coating is removed from the weld area. The coatings and any metals containing
these elements can give off toxic fumes during the welding process.
5.2 Do not weld, cut or heat lead, zinc, cadmium, mercury, beryllium or similar metals without
seeking professional advice and inspection of the welding area's ventilation. These metals
produce extreme toxic fumes, which can cause discomfort, illness and death.
5.3 Do not weld or cut near chlorinated solvents or in areas that chlorinates solvents can
enter. The heat or ultraviolet light of the arc can separate chlorinated hydrocarbons into
a toxic gas (phosgene) that can poison or suffocate the user or bystanders.
6. Check the Safety Data Sheet for the proper handling and safety precautions for
consumable welding rods as the coating can have multiple chemicals.
COMPRESSED GAS CYLINDER PRECAUTIONS
WARNING! Improper handling or maintenance of compressed gas cylinders and regulators
can result in serious injury or death. Do not use a cylinder or its contents for anything other
than its intended use.
1. Only use inert or nonflammable gas with the welding unit, such as Carbon Dioxide, Argon or
Helium with the welding unit.
1.1 Never use flammable gases, as they will ignite and may result in an explosion or fire that can
cause death or injury.
2. Do not attempt to mix gases or refill a gas cylinder. Exchange a cylinder or have it refilled by a
professional service.
3. Do not deface or alter the name, number or other markings on a cylinder. Do not rely on a
cylinder's colour to identify the contents. Do not connect a regulator to a cylinder that contains
a gas that the regulator was not designed to handle.
4. Do not expose a cylinder to excessive heat, sparks, slag, flame or any other heat source.
4.1 A cylinder exposed to temperatures above 130 °F will require water spray cooling. This
method may not be compatible with electric welding units due to the hazard of
electrocution.
