YASKAWA YWE-EH500-6N0 Instruction Manual page 6

Be sure to observe the following warnings and use protectors to protect
yourself or other people from the fumes or gases generated at welding and
short of the oxygen.
• In order to prevent gas poisoning or suffocation, be
sure to ventilate sufficiently or use an inhaler, etc.
when welding at a place specified by regulations such
as labor safety and sanitary regulations or hypoxia
preventive regulations.
• In order to prevent dust trouble or gas poisoning due to the fumes or
gases, use a local air exhaust facility specified by regulations such as
labor safety and sanitary regulations or dust trouble preventive regula-
tions or use effective protectors for breathing.
Fumes or gases generated at welding may harm your health.
• When welding within such areas as a tank, a boiler, or a ship's hold, be
sure to ventilate sufficiently or use an inhaler, etc. in order to prevent or
offset any actual or potential oxygen shortage.
Gas heavier than air such as carbon dioxide gas or argon gas stays at the bottom.
• When welding in a small space, be sure to ventilate the site sufficiently
or use an inhaler. At the same time, operations must be done under
trained supervisor.
Welding operations at a small space may result in short of the air, causing a person to be
suffocated.
• Do not perform welding near degreasing, cleaning, or spraying opera-
tions.
Failure to observe this warning may generate extremely noxious gases.
• Before welding coated steel plates, be sure to ventilate sufficiently or
use protectors for breathing.
Welding such coated steel plates generates noxious fumes or gases.
