WARNING
HYDROGEN GAS CAN CAUSE AN EXPLOSION OR FIRE
Hydrogen is a flammable gas that can cause an explosion or fire if it is not
removed.
Keep flames away from cylinders and hoses that contain hydrogen. Keep flames
and sparks away from the torch when using hydrogen as a plasma gas.
Consult your local safety, fire, and building code requirements for the storage and
use of hydrogen.
Hypertherm recommends that you install an exhaust ventilation system to remove
the hydrogen-enriched atmosphere that can collect when hydrogen is used as the
plasma gas for cutting.
Flashback arrestors are REQUIRED to stop the spread of fire to the supply gases
(unless a flashback arrestor is not available for a specific gas or pressure).
As an installer or user, you must supply the exhaust ventilation and flashback
arrestors for your cutting system. You can get them from your cutting machine
supplier.
WARNING
OXYGEN GAS CAN CAUSE A FIRE HAZARD
If you use oxygen as the plasma gas for cutting, it can cause a potential fire hazard
due to the oxygen-enriched atmosphere that collects. A fire can occur if oxygen is
not removed.
Hypertherm recommends that you install an exhaust ventilation system to remove
the oxygen-enriched atmosphere that can collect when oxygen is used as the
plasma gas for cutting.
Flashback arrestors are REQUIRED to stop the spread of fire to the supply gases
(unless a flashback arrestor is not available for a specific gas or pressure).
As an installer or user, you must supply the exhaust ventilation and flashback
arrestors for your cutting system. You can get them from your cutting machine
supplier.
