WELDING PREPERATION
9.1 Preparing the Protective Equipment
To protect you from gas generated from welding, fume, and lack of oxygen,
wear protective equipment.
To avoid gas poisoning and danger of suffocation, wear a gas mask or adequately ventilate
when the welding machine is used in the place regulated by a local law.
To prevent disorder or poisoning caused by fume, wear a gas mask or weld at a partial
exhaust facility approved by the local regulation.
Adequately ventilate or wear a gas mask when using the welding machine in a tank, a boiler,
a hold of a ship, because heavier gas such as carbon dioxide or argon gases are drifting
When using the welding machine at a narrow space, comply with a trained supervisor’s
directions. And be sure to wear a gas mask.
Do not operate the welding machine near the places where degreasing, cleansing, and
spraying are performed. Otherwise, poisonous gas may be generated.
Be sure to wear a gas mask or adequately ventilate when welding a coating steel plate.
(Poisonous gas and fume may be generated.)
NOTE:
Install a windshield to protect arc from wind when using an electric fan for
ventilation or when welding outdoors. Failure to observe the demand may result in poor
welding.
CAUTION
Use the protective equipment to protect you and other workers from arc rays,
spattering dross, and noise from welding operation.
When performing or monitoring welding operation, wear an eye protector with a good light
blocking effect or face shield.
Wear protective glasses to protect your eyes from the spattering dross.
Wear protective equipment such as protective gloves, long-sleeve clothes, leg covers, and
leather apron.
Install protective screens or barriers to protect the eyes of others in the work area from arc
ray.
Wear an ear protector when noise level is high.
